Pool Heaters

PoolCenter offers natural gas and propane pool heaters for sale, and electric pool heat pumps to warm your pool water. Polar bears may like it cold, but for the rest of us, 82-86° is just about the right temperature. Swimming pool heaters are installed next to the pool filter, and pool water is pumped through the heat exchanger. Pool heaters can add 10°, 20° or 30° F to the pool water, keeping it comfortable through 3 seasons or even all year around.

Swimming pools are the ultimate in entertainment and relaxation, but it takes a backstage when the water is cold and uninviting. Swimming pool heaters are a perfect addition to your pool equipment and allow you to maintain a comfortable water temperature for morning, evening or late season swims. 

TYPES OF POOL HEATERS: Gas swimming pool heaters are available in many makes and models, with the basic difference being the type of energy the heater uses, e.g. natural gas or liquid propane, and their ignition style, e.g. millivolt or electronic start. Millivolt pool heaters utilize a standing pilot that must stay lit constantly to initiate the pool heating process, while an electronic start pool heater eliminates the need to keep a constant pilot burning. Ultra-efficient natural gas pool heaters and low-maintenance propane pool heaters utilize the latest in technology to ensure your pool water stays at the temperature you like. 

Electric pool heat pumps operate like a reverse air conditioner. They pull warmth from the outside air to warm a refrigerant, which is compressed to generate more heat. Heat pumps are connected to a 30-60 amp breaker, and operate at less than half the cost of using gas to heat the pool. They are limited however, operating only with outside temps of 50° or higher, and they also heat slowly, adding only 3-5° per day, but can maintain the heat very efficiently. 

WHAT SIZE POOL HEATER? Calculate the surface area of your swimming pool before you purchase a pool heater in order to determine how many BTUs it will take to warm your pool water to the comfortable level. Larger pool heaters will help warm your water faster and will save on heater running cost. If you are heating a pool and an attached spa, the models over 400K BTU are normally used. For pools without a spa, you can go down in size (250K or 325K), especially if a pool cover is used to retain pool heat, or if you plan to use the heater rarely, or want to add only 10-15° to the pool water. Above ground pool gas heaters are often in the 100K BTU range. For heat pumps, above ground pool use a 50-75K BTU heater, while inground pools will look for one in the 100-150K BTU range. Larger pool heaters will heat up the pool faster, and operate less, resulting in some degree of energy savings. 

HOW MUCH DO POOL HEATERS COST? PoolCenter brings you the best in gas pool heaters from top brands like Jandy, Raypak, and Hayward – and well-known pool heat pumps by AquaCal, Hayward and Pentair. For inground pools, gas pool heaters generally cost about $2000, plus the cost to run a gas line from the meter to the heater, and some light plumbing. Pool heat pumps generally cost about $3000, plus the cost to run a power line from the main breaker box to the heater, and some light plumbing. Depending on the location of your gas meter (or LPG tank), or the location of your main breaker box, gas or electric heater installation may be easier to accomplish. On average, gas pool heaters cost about $3000 installed, and pool heat pumps cost more, over $4000 for a complete installation. For above ground pools, the cost to install a heater is less, about half of the prices of inground pool heaters. 

HOW MUCH DO POOL HEATERS COST TO RUN? Another good question, and the answer is – it depends. The cost to heat a pool depends on the temperature difference between the pool water and the outside air, and whether or not you use a pool cover (solar blanket or auto cover), to retain the heat. On average, gas pool heaters cost around $250 per month – more in cold weather, less in hot weather. For pool heat pumps that are properly sized, you can heat the pool for about $150 per month, again with higher costs in colder weather and less during warm periods.
