An electric pool heater is an excellent way to create warm and luxuriously comfortable water for your salt water pool with very little energy resulting in lower heating costs. Also known as a heat pump pool heater because it relies on heat from the environment to be converted into heat energy for your pool.
Since an electric or heat pump pool heater is able to convert even small
amounts of heat from the surrounding air they are a great option in cooler climates. Although it requires more electrical energy to convert heat to your pool in
lower temperatures, electric heaters are still more economical compared to a
gas heater in most climates.
The result of using any pool heater is nice and inviting water for your pool. If you want to extend your swimming season into weather as cool as 50F (10c) you should consider an electric pool heater. The main downside is that it does take considerably longer to heat your pool compared to a gas heater, especially in cooler weather. However, they are ideal for prolonged usage because of the very low energy consumption.
An electric swimming pool heater is a great way to heat your pool for extended periods of time. They do rely on heat from the air and are much more effective and efficient in warmer climates. If you rely on them for heat in cooler temperatures it can take some time to heat your pool. They are most effective in temperatures higher than 50F (10c).
They use small amounts of electricity to operate and utilize the heat energy from the air around the heater to produce heat for your pool, this is the reason why they are so efficient.
The air is drawn into the heater through the process of refrigeration and it creates a heated gas. This gas heats the condenser, which heats the pool water that is circulating through the heater. This process is very energy efficient, environmentally friendly and results in pool heating for a fraction of the cost of a gas heater.
An electric pool heater is intended for prolonged use because it does take longer to heat your pool compared to a gas pool heater. It still remains a more affordable option when operating more often because of its efficiency.
The efficiency is rated on a scale called Coefficient of Performance (COP). Most heaters range between 4 - 7 COP, the higher the better. A heater with a COP of 5.0 would convert every $1 of electricity into $5 of energy.
Heat pump pool heaters are also rated by British Thermal Units (BTUs). It’s different than the rating system for gas heaters. A rough guideline to determine the amount of BTUs needed to heat your pool adequately is:
An example would be a pool with dimensions 30ft x 15ft =
450ft surface area. A pool with a surface area of 450 sq ft would require a heater
with approximately 68,000 BTUs.
It’s important to remember that you should always consider a pool heater with about 10% higher BTU rating just to be sure you have adequate heating. If you get a larger heater you will heat your pool faster, use it less often and potentially increase the life of your heater. Heat pump pool heaters are an environmentally friendly choice for heating your pool since there are no emissions and they require a lot less energy than gas heaters.
An electric pool heater is a smart choice when considering pool heating. If you live in a climate where you want to extend your pool usage a couple months they will get the job done for a very reasonable cost.
