SPA HOTTUB and SWIM SPA INFORMATION A design which has been around since the 1970’s which not too many people really known about is the “swim spa”. A swim spa which is also known as an endless pool, which can be above ground or in ground, looks like long spa or a small pool. The design of a swim spa allows the user to swim in place, or do other exercises. Some models have under water tread mills, rowing simulation and other aerobic activities. Just like a normal hot tub they are made from acrylic and are usually between 12’-24’ in length and hold from 600-2000 gallons. Since a huge tub would be very expensive to heat, and since you probably wouldn’t want hot water while you are exercising, some designs often have a separate area that acts as a hot tub spa. The swim spa itself usually uses a large fan combined with jets that can displace hundreds of gallons per minute, which is necessary for swimming resistance. Swim spas often a perfect form of exercising. Hydro static pressure or the bouncy of your body in the water takes additional stress off the heart and other muscles, giving you the ability to exercise your body in a slightly different way. Some professional swimmers actually prefer swim spas instead of doing laps in a pool because the current created gives them extra resistance, much like swim against currents and waves in a large body of water and exercising all parts of the body, giving better muscle tone and more of a challenge. You should note that since exercise increases the body’s temperature, it wouldn’t be too wise to exercise in highly heated spa. Should your body overheat and you lose consciousness in the water, you would drown. You can even purchase swim spa kits to create a swimming lane for an existing pool, or a custom addition or add on for a spa. Due to these spas size, they will use considerable more electricity than the average hot tub. An average hot tub by its self is the appliance that will consume the most electricity of any other of your household products. So it will make a huge difference if you do all you can when choosing specific designs while shopping. Below are some things that you can look for to help assist you in your searching. Look for spas that have CA Title 20 or that have been approved otherwise by the CEC (California Energy Commission) for better energy efficiency. Having a smaller pump to take care of heating and cleaning the spa when it is not in direct use will save you considerably compared to a conventional single pump with multiple speeds for the different cycles A Venturi air injects mixes air with the water for a more robust massage without needing electricity like an average air pump Insulation is crucial to maintaining tub temperature if you’re using heat, and making sure energy doesn’t go to waste. Six inches of foam insulation is recommended as well as the highest R rated cover you can find.
