The basic rule is to install heating systems based on your use. Indeed, price and performance of the different systems vary widely. These systems are placed at the exit of the filter and often in a separate room.
So if you enjoy your swimming pool a few times a month, then choose the least expensive system which is an electrical system. However, if you want to use your pool every other day for example, then choose a heat pump. It will cost more but quality will be there.
Also, you can consider adding a heat retention pool cover to optimize energy consumption.
Different types of pool heaters
There are three basic types of pool heaters. The best system for your pool is determined by numerous factors including your needs, desires, budget and physical layout of the pool and house :
- Solar Pool Heaters are the most effective, best value and best environmental choice for heating your pool no matter what climate your pool is in
- Heat Pump Heater can efficiently collect heat from the outside air down to the 45 to 50 degree range. For tropic and sub tropic climates, this means that the pool can be maintained at 80 to 90 degrees under almost all conditions all year round. In northern climates, a Heat Pump will greatly extend your swimming season
- Propane and Natural Gas Heater have the highest operating cost, and are the least efficient / cost effective way to heat a pool, but if you require rapid heat up, constant temperature regardless of outside temperature, or you are heating a spa or hot tub, then a gas heater may be right for you
