If you have a swimming pool at home then cooling off in summer is no problem for you. In the springtime, however, when you do jump into the water it will be so cold it will take your breath away. Even on the hottest days a pool can still be very cold. This makes your pool only usable during the hottest summer months. At Pool Supply Unlimited we have a comprehensive selection of the best pool and spa heaters on the market to allow you to make the most of this great investment.

We have gas pool heaters that you can install with pumps that circulate the pool water to warm it up before it is returned to the pool. In some states, it is compulsory to only use low emission pool heaters and we are pleased to supply this range as well, all in top, well-known, reliable name brands. When you install pool heaters they will warm your pool to a comfortable temperature. We have compact pool heaters for residential swimming pools, up to commercial heaters and boilers for large school swimming pools and gym pools.

Gas pool heaters offer you a cheap source of supplying energy for heating your pool and they are completely safe to use, and cost-effective as well. If you would prefer to have electric pool heaters we have top quality models to choose from in different sized models, equally effective to add for in-line pool heaters. Enjoy using your pool well into the fall if you have smart swimming pool heaters installed.

Pool Supply Unlimited is a licensed and registered dealer for many of the top brand names of pool heating and equipment. Get expert advice on the best equipment for your residential and commercial swimming pools from a company that has been in the pool business for over two decades.

It is recommended to have equipment of this nature installed by the professionals, and we will be able to recommend reputable contractors in your area if you need help with this option.
