Proper Hot Tub Filter Cleaning & Maintenance

Proper Hot Tub Filter Cleaning & Maintenance

You won’t see Hot Tub Filter Cleaning and Maintenance on anyone’s bucket list, but it’s one of the most important “must-do’s” for hot tub owners.

This task isn’t nearly as bad as most people would have you believe, but it can be if you don’t clean and maintain your filter in a regular basis.

You can’t have a healthy, safe and enjoyable hot tub experience without a filter, so it’s in your best interest to find out the most cost effective, least time consuming and easiest way to keep your filter clean.

Why Do Hot Tubs Need Filters?

• Filters protect your hot tub equipment from harsh or damaging particles in the water that can clog your system or damage your system’s components. Well maintained filters catch nasty particles before they do clog or damage your system.

• Filters also collect bacteria that goes unseen to the human eye. This creates a safer, cleaner and healthier environment for you, your friends and your family to soak in. Why worry about the dangers of pathogens in your hot tub water if you don’t have to.

• You’ll spend a lot less time picking debris, leaves and unwanted additions out of your hot tub if you maintain your filter on a regular basis.

• Not maintaining your hot tub filter may actually void the hot tub manufacturer’s warranty. That alone makes checking and cleaning your hot tub filter at least once or twice a month and replacing your filter every 6 months or once a year at the very least.

Quick Cleaning Vs. Deep Cleaning

Quick Filter Cleanings are easy, entail little or no chemicals and should be done regularly. The easiest method is to simply remove the filter, rinse it down well with a hose, let it dry and then put it back in the hot tub.

For a better, longer lasting clean, use an instant cartridge cleaner or a Water Wand Filter Cleaner.  You can spray most cartridge cleaners right on the filter, let it soak for a short period of time and then rinse it off with a hose.

The Water Wand Filter Cleaner, pictured on the right, is the worlds first hand-held cartridge filter cleaner. It is highly effective at cleaning all hot tub pleated filter cartridges in significantly less time and uses less water than traditional filter cleaning methods.

Deep Cleaning takes several hours, can be done overnight and should be done about every 6 months. Unlike Quick Cleaning, deep cleaning requires the use of a filter cleaning chemicals. The most common deep cleaning method is soaking your filter in a diluted solution of water and filter cleaning chemicals overnight in a bucket.

The bucket must be large enough so that your filter will be entirely submerged in the solution. For the best results, follow the manufacturer’s instructions and let your filter soak overnight. Remove the filter in the morning, rinse if off thoroughly with a garden hose and let it dry off completely before putting it back in your hot tub.

Basic Filter Maintenance Schedule:

• Quick Cleaning Once Every Two Weeks
• Deep Filter Cleaning Once Every 2-3 Months
• Filter Replacement Every 12 Months

Why Hot Tub Temperatures Max Out at 104 Degrees

Many people question why their spa will only heat to 104 ºF. Throughout history public bathing was done at higher temperatures. Even today, in Japan, many public bath houses have water up to 115 ºF.

Hot tubs & spas in the United States, Canada and most parts of the world have been regulated to obtain a maximum temperature of 104 ºF since 1980. On Dec 31, 1979, the Consumer Products Safety Commission, CSPC, released advisory #79-071.

The advisory warned that heat strokes could be caused by water temperatures of 106 °F or higher. The CSPC recommended a maximum temperature of 104°F for both public and private hot tubs and spas.

The advisory was adopted by Underwriters Laboratory (UL) and lists it in their controlling document (#UL 1563) for home spas, equipment assemblies and associated equipment. The relevant portion of this document as it pertains to max temp regulations for home tubs and spas is section 32; Temperature Regulating Controls…

32.1 – A unit shall be provided with a water temperature regulating control that has a maximum set point of 40 °C (104 °F) in the tub.

32.2 – The temperature regulating control shall be adjustable and shall have marked settings, but it shall not have any settings marked hotter than 40 °C (104 °F).

32.3 – A digital temperature regulating control that displays the selected temperature, but no higher than 40 °C (104 °F), may additionally display the actual temperature of the water.

UL has strongly advised that any hot tub or spa manufacturer that produces a control, or modifies a standard control, to exceed 104 °F is in violation of their UL listing and can have their listing pulled by UL.

The actual 1980 CSPC cover letter that accompanied advisory #79-071 is listed below:

U.S. Consumer Product Safety Commission Warns of Hot Tub Temperatures
Release # 79-071
December 31, 1979

WASHINGTON, D.C. (December 31, 1979) — Safety officials frequently warn the public about the dangers of drinking and driving. Now the U.S. Consumer Product Safety Commission is cautioning that drinking and hot tubing do not mix well either.

According to CPSC staffers, the use of hot tubs at water temperatures above the normal body temperatures can cause drowsiness which may lead to unconsciousness and subsequently result in drowning.

The risk of drowning is significantly heightened if individuals consume alcoholic beverages while, or prior to, soaking in hot water, CPSC staff warns. The Commission has been informed of 10 deaths recorded so far in 1979, three of which involved alcohol-related drowning in hot tubs heated to approximately 110 degrees Fahrenheit.

Even if no alcohol is consumed, extremely hot water during hot tub use can threaten life, CPSC reports. Soaking in a hot tub with water heated to 106 degrees Fahrenheit, for example, can raise human body temperature to the point of heat stroke (or impairment of the body’s ability to regulate its internal temperature). These conditions can be fatal even to fully healthy adults.

Hot tub sales in the U.S. have increased about 125 percent in the past two years, from approximately 40,000 tubs sold in 1977 to approximately 90,000 sold this year. Based on industry projections, CPSC estimates that sales could climb as high as 135,000 tubs next year, a 50 per cent increase over 1979 sales.

As hot tubs have gained in popularity throughout the nation, so have concerns at CPSC that consumers learn how to use these products safely. Accordingly, CPSC staff strongly urges consumers to observe the following safety rules for hot tub use.

Safety Rules For Hot Tubs

  • Hot tub water temperatures should never exceed 104 degrees Fahrenheit. A temperature of 100 degrees is considered safe for a healthy adult. Special caution is suggested for young children.
  • Excessive drinking during hot tub use can cause drowsiness which could lead to unconsciousness and subsequently result in drowning.
  • Pregnant women beware! Soaking in water above 102 degrees Fahrenheit can cause fetal damage during the first three months of pregnancy (resulting in the birth of a brain damaged or deformed child). Pregnant women should stick to the 100-degree maximum rule.
  • Before entering the hot tub, users should check the water temperature with an accurate thermometer; hot tub thermostats may err in in regulating water temperatures by as much as four degrees.
  • Persons with medical history of heart disease, circulatory problems, and diabetes or blood pressure problems should obtain their physician’s advice before using hot tubs.
  • Persons taking medications which induce drowsiness, such as tranquilizers, anti-histamines or anti-coagulants, should not use hot tubs.

CPSC staff currently is working with staff from the Spa and Tub Association ( a division of the National Swimming Pool Institute) and the International Spa and Tub Institute (both of Santa Ana, California) as they develop voluntary safety standards for the manufacture, installation, and use of hot tubs. These standards, which are expected to reflect many of the above safety warnings, may take effect as soon as spring, 1980.



Filter Cartridge Cleaning Process

Cleaning Instructions for Unicel Spa Filter Cartridges

Filter Cartridge Cleaning Process

1.    Remove the cartridge from the filter housing following the manufacturer’s instructions.

2.    Use a garden hose with a straight flow nozzle to wash down the filter element. Work from the bottom down, holding the nozzle at a 45-degree angle, and wash all the pleats with emphasis between pleats.

3.    Rinse until all dirt and debris is gone.

4.    For all spa cartridges and elements used in swimming pools where perspiration, suntan lotions, and other oils are present, soak the element for at least one hour (over night is most effective) in (1) a filter cleaner; or (2) one cup tri-sodium phosphate (tsp.) to five gallons of water.

5.    Rinse the cartridge again to remove oils and cleaning solution.

6.    If the filter has a coating of algae, calcium carbonate (residue from the calcium hypochlorite), iron or other minerals, soak the cartridge in a solution of one part muriatic acid to twenty parts water until all bubbling stops.

*WARNING: failure to remove all oils and cleaning solution before acid soaking will result in a permanent restriction of water flow and cause premature cartridge failure.

7.    Rinse the cartridge clean and reassemble housing.

Please Note: Unicel does not recommend the use of diatomaceous earth (DE) with cartridge filters. DE particles can become trapped in the body of the media and shorten cartridge life. If desired, a cellulose fiber (synthetic DE) can be used in moderation.

Baquacil as a Sanitizer

If you use baquacil as a sanitizer, the filter element must be cleaned with Baqua Clean before any cleaner is used.

Unlike chlorine, which oxidizes the bacteria in the water, the active ingredient in Baquacil, polyhexamethylene biqunaide or PHMB, destroys the bacterial cells. PHMB locates and binds to the bacterial surfaces, and then attacks the outer bacterial wall.

Once this wall has been compromised, the inner cell membrane, or cytoplasm membrane, is destroyed. This destruction allows the cell contents to disperse into their surroundings where they are further broken down into their elemental parts by Baqua Shock, a non-chlorine oxidizer.

In addition, Baquacil is a mild coagulant, which combines bacterial cells and other small particles in the environment into particles large enough to be trapped by the filter.

The resulting deposit is a gray sticky film on the media, which can only be removed with Baqua Clean. If trisodium phosphate (TSP) or any TSP type cleaner is used prior to stripping the film, the cleaner and the gray film will combine to form a gum-like substance.

Once this occurs, the substance cannot be removed from the media and the filter cartridge must be replaced.

WARNING: Follow all manufacturers’ instructions, warnings and precautions when using Baquacil, Baqua Shocks and/or Baqua Clean.

Proper Care, Storage & Shelf Life of Reagents

Reagents that are stored properly maintain have a much longer shelf life and maintain their maximum effectiveness than those that are improperly stored. This includes all reagents including liquids, powders, crystals, tablets and test-strips.

Reagents should not be stored in moist or damp areas and should be kept dry and moisture free at all times. Powders, crystals and acids are very stable and have an excellent shelf life if kept dry and aren’t exposed to sunlight.

The date of manufacture is not the controlling factor when it comes to reagent shelf life; the storage conditions are much more important. As with all perishables, reagents are sensitive to environmental influences and will last longer under controlled conditions.

Taylor Technologies Recommends the Following Care for Reagents

Storing reagents at a consistent temperature in the range of 36°–85°F (2°–29°C). Dramatic temperature fluctuations, such as being stored near a refrigerator or in the trunk of a hot car, causes reagents to rapidly deteriorate.

Avoid exposing reagents to prolonged direct sunlight. Most manufacturers use brown plastic bottles to help protect light sensitive reagents for this very reason, but prolonged overexposure to direct sunlight will quickly deteriorate any reagents effectiveness.

Keep reagents separate from other non-reagent water treatment chemicals.

Replacing reagent caps immediately after use and tighten them carefully to limit their exposure to air and humidity.

Don’t switch reagent bottle caps. Placing bottle caps on soiled surfaces, re-pouring reagents into possibly contaminated containers and touching test strip pads can easily contaminate reagents.

The experts at Taylor formulate their reagents to remain fully effective for a minimum of one year, with very few exceptions.

As a general precaution and rule of thumb, you should replace any reagents that are more than one year old or at the beginning of each new testing season.

Hot Tub Ionizers

Hot Tub Ionizers

Nobody enjoys soaking in a dirty or unhealthy hot tub and owners go to great lengths to ensure an enjoyable and relaxing soaking experience in water that’s as clean, safe and healthy as possible.

How do we get our tub and spa water as clean and safe as possible? Simple, by adding chemical sanitizers, pH balancers, oxidizers, clarifiers, calcium boosters, metal removers, water softeners, enzymes and algaecides etc…

If you’re tired of trying to relax in a tub full of chemicals and want to drastically reduce your use of costly chemicals by 80% – 90%, then the Hot Tub Ionizer is the system for you.

In all cases, Ionization is safer and more forgiving than typical chemical treatments.  Ionizers provide softer, gentler water and a more comfortable environment.

It’s much less expensive than chemical treatments and it will increase the life expectancy of everything around the hot tub. That includes bathing suits, pumps, filters, heaters and the rest of your spa equipment.

The Hot Tub Ionizer will save you time and money every year as well as provide you with the following benefits:


• Low Initial Cost
• Superior Water Quality
• Reduces Chemical Use by 80-90 %.
• Lifetime Warranty
• Adds Years of Life to Spa Covers & Equipment
• Reduced Maintenance
• No More Algae Problems
• No More Red Itchy Eyes
• No More Dried Out Skin
• Simple to Install & Operate
• Weatherproofed for Outdoor Installation

How Do Ionizers Work?

Ionizers use a natural water purification process called electrolysis. It starts with an ultra-low voltage charge running through a sacrificial mineral electrode installed in the return line.

This direct current causes the release of copper and zinc ions into the flow of water which aids in the destruction of algae, bacteria, viruses and mold.

To maintain clean, clear, safe and healthy water all you need to do is add a small amount of chlorine or non chlorine shock to your hot tub after each use to kill any organic material in your hot tub.

Why try to relax in a tub full of harsh expensive chemicals when a soothing hot spring-like hot tub experience is just an Ionizer away!

What’s So Different About Our Hot Tub Ionizer?

Our electrodes are custom made from a copper and zinc alloy specifically designed for water treatment. They are four times larger than most spa ionizers, so our electrodes last longer and the replacement electrodes are a better value.

What About Passive Cartridge Ionizers like Nature 2?

You should not use cartridge ionizers. Not only are they very expensive and need to be replaced every few months, you also have little or no control as to the amount of ionization being produced.

Cartridge Ionizers are sold without test kits so you never know what the ion level is or if it’s safe to reduce the sanitizer level. Hands down, the best and most cost effective method of ionizing a hot tub is with an electronic ionizer.

Please note that all hot tub ionizers are created equally. Beware of copper only ionizers with electrodes and a control box that may look like our Hot Tub Ionizer, but are nothing more than cheap knock-offs made from outdated electronics.

Features of our Hot Tub Ionizer include:

• Treats up to 1,200 Gallons
• Adjustable Output for Precise Metering of Ion Production.
• IP66 Rated Weatherproof Controller Protects Electronics from Moisture, Corrosion, and Harsh Environments.
• High Efficiency UL, CSA, and CE listed Auto Ranging (120 or 240 volt) Switching Power Supply which provides 5 volts DC to the controller (must be wired to the pump timer so it has power only when the pump is running.)
• Solid State Electronic Circuitry with Automatic Sequential Polarity Switching to keep Electrodes Clean and Even Wearing.
• Light Emitting Diodes Display Power, Cell Power, and Polarity.
• Has Threaded Electrode Cell with a 2″ Tee Fitting, Sealed Electrical Connections so there are No Corrosion Problems, and 1-1/2″ Reducing Bushings if Needed.
• Lifetime Warranty.


• INPUT VOLTAGE: 120 or 240 Volts AC.
• INPUT FREQUENCY: 50 to 60 Hertz
• CONTROLLER: Plastic Weather Proof
• FLOW RATE: 10 To 120 GPM
• CELL: 2″ Tee with Extention and 2″Threaded Fitting
• CELL REPLACEMENT: 2″ Threaded Male Fitting
• ELECTRODE SIZE AND TYPE: 1-1/2″ Half Round x 2-1/2″ LONG – COPPER & ZINC
• CAPACITY: UP TO 1,200 Gallons

Hot Tub Ionizer Operation

1. Turn on the Hot Tub pump.
2. Test the Hot Tub water and make sure the water is properly balanced and sanitized. Test the water with the copper test kit to see if there is copper already present. If copper is already present it may be from a copper based algaecide or from a previous pH problem.
3. Turn the controller output to MAX. The power light and the cell power light should come on. The cell power light will change color from red to green every few minutes to indicate the cleaning circuit is operating properly. Turning the control down towards MIN decreases the voltage and current to the cell. The Cell Power light will dim slightly as the control is turned down.
4. Now you can stop using heavy sanitizer levels! All you need to do is maintain a constant chlorine level as low as 0.2 pp. It has been proven that maintaining 0.2 ppm chlorine and 0.2 ppm copper is more effective sanitation than using just chlorine at 2.0 ppm.
5. Test the copper level at least once a week until you have found the proper setting for your spa. Now you should only need to test the copper level once or twice a month because the copper level does not dissipate like sanitizers.
6. Do not over ionize your spa. When the level reaches 0.3 ppm turn the control down and adjust as necessary to maintain 0.3 ppm. If the copper level reaches 0.5 ppm turn the ionizer to MIN until the level drops to 0.3 ppm. Maintain the pH at 7.2 to 7.6. Failure to maintain your pH could result in staining if the pH is allowed to drift above 8.0.

Hot Tub Ionizer Installation

1. Before installing the Ionizer the Hot Tub should be clean, pH balanced, sanitized and the filter cleaned.
2. Turn off the power to the spa equipment.
3. Install the cell after the hot tub heater if possible. The electrode cell must be at the bottom or side so that no air will be trapped in the cell. Cut a section of pipe out where the electrode cell will be installed. Glue the TEE in place using PVC glue making sure it is oriented so no air will be trapped in the cell.
4. Mount the Controller on a vertical surface at least 5 ft from the Hot Tub. Fasten with the 4 #6 x 3/4′ screws provided, so that the cord to the cell and the power cord will reach. It is best to install the controller where it is protected from the sun and weather.
5. Wire the ionizer controller into the same circuit as the low speed of the pump (some spa controllers have a circuit designated for “ozone”, which can also be used).  If connected to 120 volts the brown wire is the hot wire, the blue wire is the neutral wire, and the green wire is the ground. If connected to 240 volts the brown and blue are the hot wires and the green is the ground. The ionizer controller automatically adjusts to the incoming voltage.

Hot Water Hydrotherapy and Its Health Benefits

Hot Water Hydrotherapy is the medicinal use of water for positive health benefits.

These health benefits come from the mechanical and thermal effects of water interacting with the body.

It includes the use of physical water properties, specifically temperature and pressure, to manipulate the body’s flow of blood, the endocrine system and associated neural systems in order to treat the symptoms of certain diseases.

The Physical Effects Of Hot Water Hydrotherapy On the Body

Hydrotherapy uses water to deliver temperature and pressure changes to the body. These changes are sensed by the body via nerve endings in the skin and muscle, and result in neural “reflex effects” that are controlled by the brain and spinal cord.

The most important of these reflex effects are vasodilatation and vasoconstriction, which are the terms used to describe the relaxation and tensing of the blood vessels in the body.

These physical changes in the blood vessels cause changes in the rate of blood flow and in the metabolic functions that are linked to the rate of blood flow.

Hot Water Hydrotherapy

In a reflexive response to external heat, your body initiates changes that help keep the body cool, including dilating blood vessels to increase the blood flow through them, diverting blood flow to the extremities and to the skin’s surface, opening the pores of the skin, activating sweat glands and relaxing muscles.

Over short durations, a hot bath will cause organs of the endocrine system to become less active, particularly the adrenal gland, and can decrease blood pressure. This results in a relaxed, less stressful state and helps calm the nervous system.

Inhaling the steam or vapor from hot water hydrotherapy can be beneficial effect for your lungs as well.

Moist, hot air causes the small airways and air sacs in the lungs to dilate and increases the lung’s ability to move phlegm and mucus out. It can also help people breathe in more easily, since the volume of space in the lungs slightly increases.

The Physical Nature of Hot Water in Hydrotherapy

In addition to temperature, the physical nature and pressure of water used in soaking, full body immersion or Hot Tub Hydrotherapy plays an important role in hot waters effect on the body.

Weightlessness – In water, you weigh 10% of your actual body weight, so your body is relieved of the normal pressures exerted by gravity. This “weightlessness” alleviates pressure on joints and muscles (muscles don’t have to work as hard to keep body in position) helping to ease pain.

Water pressure & Underwater Exercise– Because water is denser than air, water pushes on your body more than air, helping to support body joints and muscles and making it more difficult for fluids to accumulate under the skin or in extremities.

The pressure water exerts on your skin and muscles as you move your body through water can also help move blood through the veins and back towards the heart.

Water produces a soothing, massage-like sensation on the skin that results in specific responses from the brain that help calm and soothe the body.

That effect is further heightened by the addition of water jets or air bubbles to the water, which enhance the sensations on the skin and in the muscles.

Water Jets – A light massage from water jets activates nerves in the skin and muscles that increase blood circulation to the massage area resulting in better tissue oxygenation, toxin evacuation, and muscle relaxation.

Air Bubbles – The gentle, tingling sensation people experience on the skin from the presence of many tiny air bubbles in water causes certain neural reflexes to activate, resulting in beneficial chemical reactions that promote muscle relaxation and a mental state of contentment.

Health Benefits of Hot Water Hydrotherapy

Hydrotherapy regiments can be designed to treat any number of maladies by creating different combinations of water temperature, water pressure and delivery methods. The most common ailments Hydrotherapy is used to treat include arthritis pain, back pain, headaches and muscle pain.


These ailments respond well to changes in the body that are brought about by temperature and pressure differentials and by increased or decreased blood flow. Hydrotherapy is also useful for relieving the discomfort and pain caused by a variety of symptoms associated with different diseases and injuries.

Hot Water Hydrotherapy is the most popular home Hydrotherapy remedy, not only because it is the most comfortable and enjoyable form of Hydrotherapy, but also because it stimulates nerve reflexes that result in the calming of the lungs, heart, stomach and endocrine system.

It is often used to relax patients, promote blood flow, aid in the healing process, tone the body, stimulate the immune system and alleviate the pain or discomfort associated with deep muscle, joint or connective tissue ailments, injuries or abnormalities.

Increased blood flow has important positive effects on our bodies. More efficient oxygenation of tissues helps injuries heal faster and more efficient removal of toxins from tissue helps prevent injuries and increases tissue resiliency.

Hot Water Hydrotherapy is used to achieve a wide variety of positive health benefits including:

• Fights Infection & Injury – By increasing the rate of blood flow in the body, hot water Hydrotherapy increases circulation of the immune system’s white blood cells, enabling the immune system to work faster and more efficiently.

A hot soak increases the production of endorphins in the body as well. Endorphins are the body’s “pain killers” and are associated with feelings of elation or happiness. Endorphins also stimulate the immune system, alleviate pain, and help tissues heal faster.

• Helps Clear Respiratory Infections – The inhalation of steam, particularly those medicated with compounds like menthol, alleviates the constriction of swollen lung canals and air sacs, allowing fluids and mucus to move out of the lungs more readily, and oxygen into the lungs more efficiently.

When your body fights lung infections, they move the ‘remains’ of organisms it has killed (and your spent white blood cells) out of your body via mucus, so clearing mucus and fluid out of your lungs is important in helping your body clear an infection as quickly as possible.

• Reduces Pain & Inflammation from Arthritis and Rheumatisms – The increase in blood flow brought about by hot water helps muscles relax, which lessens stress and pressure on joints, thereby alleviating pain from arthritis and rheumatism.

Inflammation in surrounding muscles and connective tissue is caused by a combination of cellular reactions to injury and a buildup of fluids, and when blood flow is increased, the body is able to reabsorb fluids faster and heal injury faster, helping reduce inflammation over time.

• Helps Improve Sleep & Relieve Stress – The calming effects hot water has on the nervous and endocrine systems help put our bodies in a “lower gear”, thereby relaxing us mentally.

This state of heightened relaxation makes it easier for us to fall asleep and helps alleviate daily stress and anxiety.

• Prevents Headaches – When blood vessels dilate, the physical space our blood has to fill in our bodies increases, and therefore overall systemic blood pressure decreases. Headaches are often brought about by high pressure in the arteries of the skull, so lower blood pressure helps prevent this from happening.

In addition, stress is often a culprit of constricted blood flow to the brain, which can also lead to headaches. Since hot water Hydrotherapy treatments help alleviate stress, they can also limit the onset of stress-induced headaches as well.

• Helps Control Blood Sugar in Diabetics – Recent studies published in the New England Journal of Medicine have shown that people with Type 2 Diabetes had an easier time controlling their plasma sugar levels and weight when they soaked in hot water for 30 minutes a day, 6 days a week.

In some instances, people needed less insulin each day as well. The increased blood flow, which mimics exercise and decreases activity of the endocrine system while increasing blood circulation to and from tissues, plays a role in the body’s ability to maintain glucose levels. Hydrotherapy is especially helpful in alleviating painful symptoms in people who have a harder time exercising than those who do not.

• Reduces Symptoms in Patients with Nerve, Muscle or Connective Tissue Diseases – Because hot water Hydrotherapy has a calming effect on the nervous system and helps increase blood flow to soft tissue, it helps alleviate symptoms associated with neural and muscular diseases by decreasing demands on neurons, decreasing stress in the muscles, and increasing the flow of oxygen to soft tissues, which aids in healing.

• Relaxes Muscles, Heals Muscle Injuries & Relieves Muscle Disease Symptoms – Hot water Hydrotherapy is especially helpful in bringing increased blood flow to the soft tissues of the body, particularly the muscles. In cases where people suffer from muscle injury or disease, hot water Hydrotherapy can provide great relief from many muscle discomforts including cramps, swelling, pain and spasms.

• Treats Circulatory Problems – When blood vessels dilate, as they do during hot water Hydrotherapy treatment, circulation and blood flow is increased, particularly to soft tissue like muscles. This is especially helpful in people who suffer from circulation problems, especially to the limbs and extremities.

People who suffer from cold hands and feet will find that many times hot Hydrotherapy doesn’t only provide an immediate relief, but that it continues to help even hours after the initial soaking period.

Hot Water Hydrotherapy Precautions

While Hydrotherapy has many potentially beneficial health effects, too much heat can affect health adversely.

In addition, people with certain types of diseases and health problems should avoid Hydrotherapy or only use Hydrotherapy under the direct supervision of a physician.

In all cases, it is important to discuss your Hydrotherapy plans with your doctor before starting Hydrotherapy and follow his or her advice and direction.

Once you have embarked upon your Hot Water Hydrotherapy regiment, be sure to monitor your progress and report any issues or side effects that arise to your doctor so they can make adjustments as needed.

Hot Tub & Spa Energy Saving & Water Conservation Tips

The list below contains energy saving and water conservation tips for Hot Tub and Spa owners from various Government Agencies and Municipalities.

1. Reset Thermostat – Some hot tubs and spas come preset @ 104 degrees. You can save energy and reduce your monthly utility bill by setting your hot tub heater thermostat to maintain 102 degrees Fahrenheit without noticing a drop off in water temperature.

2. Shift Hot Tub Water Heating to Off-Peak Times – If your hot tub or spa has a timer, you can reduce peak loads and pressure on utility rates by programming the timer to “off” during peak hours (6 a.m. to 10 a.m. and 5 p.m. to 9 p.m.) A well-insulated, energy efficient hot tub will maintain temperature for several hours after the heater is turned off.

3. Turn Down the Thermostat When You’re on Vacation – The majority of hot tub and spa owners don’t turn down or turn off their tub heating thermostats when they go on vacation or are away from home for an extended period of time.

If you won’t be using your hot tub for 5 or more consecutive days, you can save money and energy by turning your tub heating thermostat off or down to a point that it should not come on while you are away from home.

4. Reduce Pumping Cycles – Normally filtration cycles for many single and two speed pumps are set for four hours. You may be able to reduce the filtration cycles to three hours – during off-peak hours.

This adjustment should be based on your usage pattern, so you can maintain clear, clean and safe water. If your spa has a low wattage circulation pump – leave it alone, it’s designed to run continuously.

5. Use a Highly Rated Insulating Foam Hot Tub or Spa Cover – Standard covers have an insulating value of approximately R-12 to R-14 (though we offer spa covers as high as R-22). Keeping a cover in good condition is essential because most heat loss will be through the spa cover. Replace the cover if the interior foam is broken or water-saturated.

A water-logged cover will increase energy consumption from heat loss. Make sure the cover and tub lip fit snugly, straps are tied and the cover is latched when the hot tub is not in use.

This will reduce heat leakage. To handle the cover more easily and extend its life, consider using a lifting system.

6. Add a Floating Thermal Blanket – An energy-efficient floating thermal blanket will help retain heat and reduces the amount of moisture build-up on the inside of your cover. Adding just a 1/4″ closed-cell foam floating blanket under your hard cover can increase your total R-value by 4.

7. Avoid Wasting Water – Repair any leaks and adjust jets or use booster pads to adjust your height so you’re not sending streams of water on the deck.

8. Drain Your Hot Tub Only When Necessary – Hot tubs that are heavily used should be drained every 3 – 4 months. To conserve our water resources, use your old tub water to irrigate your landscaping or water your lawn.

Make sure that most or all of the chemicals in your tub water have evaporated or been filtered out before using for irrigation purposes. Waiting a minimum of 48-72 hours from the time any chemicals were last used is more than sufficient.

9. Create Windbreaks Around Your Hot Tub or Spa
– Cutting wind exposure can greatly reduce heat lose which saves energy and money. Fencing, landscaping and privacy panels, like the image on the right, can all be very effective windbreaks.

Pregnancy – Hot Tub, Spa & Sauna Use

Raising your core body temperature (hyperthermia) can harm your fetus, particularly during the early weeks of organ development. While experts don’t forbid hot tub or sauna use, they do advise caution.

Hyperthermia during the first weeks of fetal development has been linked to neural tube defects. So pregnant women are advised to treat a high fever with acetaminophen and to avoid other causes of hyperthermia.

There is no firmly established temperature or length of exposure that is considered safe during pregnancy. If you use a hot tub or sauna during pregnancy, be conservative. Avoid uncomfortably high temperatures, and limit your exposure.

The American Academy of Pediatrics and the American College of Obstetricians and Gynecologists suggest sauna use of no more than 15 minutes and hot tub use of no more than 10 minutes. To help keep your body temperature down in a hot tub, sit with your arms and upper torso above the water.

Type 2 Diabetes Hot Tub Therapy

Under the direction of their physicians, many type 2 diabetes patients use their hot tubs for therapy, but is it safe. If you’re a diabetic, chances are high that you’ve heard, read or seen signs posted warning diabetics about hot tub use.

Type 1 diabetes sufferers should absolutely not use hot tubs or hot tub therapy, but what about Type 2 diabetic patients?

A study by the New England Journal of Medicine conducted a study that showed a decrease in glucose level, and an increased overall sense of well-being for Type 2 diabetics that used hot tubs on a regular basis.

Dr. Philip Hooper of Colorado University originally conducted the study to test if hot tub immersion would stimulate exercise in diabetes patients. The test subjects, all with type 2 diabetes, sat in the hot tub for 30 minutes, 6 days a week, for 3 weeks.

At the end of the study, the all patients experienced weight loss and lowered blood sugar levels, and another patient was able to reduce his insulin intake by 18%.

The original intent of the study, to see if increased blood flow would stimulate exercise, also proved promising. Patients previously unable to exercise showing increased mobility. Aside from the medical benefits that the study revealed, Dr. Hooper noticed other benefits to hot tub use for diabetes sufferers – the patients were reporting better sleep and increased sense of well-being.

Dr. Hooper notes that hot tub use for diabetics is a lifestyle change, a positive one for diabetics if it can decrease stress and improve sleep – all factors that are important for type 2 diabetes sufferers.

8 Tips for Type 2 Diabetic Hot Tub Use

1. Talk to your doctor about warm water or hot tub therapy first and foremost

2. Use the hot tub at the end of the day, after the most strenuous activities of the day have been completed.

3. Never hot tub alone!

4. Check your glucose levels before getting into the hot tub. If your levels are spiking or dropping, wait until they become normal.

5. Make sure the water temperature does not exceed 104 degrees. Damaged nerve endings in the feet could cause accidentally burning with higher temperatures.

6. Only use a clean and well balanced spa to prevent risk of bacterial infections.

7. Using a hot tub may cause a drop in blood pressure, so exit the tub very slowly and with assistance. You will not feel the dizziness until you stand up.

8. Use hot tub therapy along with other therapies such as diet and exercise.
