Electric Pool Heater FAQ

What Is an Electric Pool Heater and How Does It Work?

Electric pool heaters are an excellent way of keeping your swimming pool’s water warm. Electric pool heaters warm up the water inside a heating tank, then pump the warm water out to the pool.

The electric pool heater keeps pumping in cold water, and pumping out warm water, giving you the best warm pool experience during the cold months.

There are two types of electric pool heaters: the water-source heat pumps and the air-source heat pumps. Each one achieves the same goal, but they work differently.

A water-source heat pump uses electricity to turn the water into gas. It then moves that hot gas back into the water. It’s called water-source because it operates by using the water inside the pool.

The air-source heat pump uses electricity to draw heat from the air. Then, it proceeds to use that heat to warm up the pool’s water.

Both air-source and water-source are good options, and in the end, it depends on your type of pool and the amount of energy you are planning to invest. Electric pool heaters can last twice as long as gas heaters. However, if you don’t live in a cold climate, electric heaters are your best choice.

What Size Electric Pool Heater Do I Need?

The heater you need depends on your pool’s size and if it is an indoor or outdoor pool. There are other factors to consider like how hot you like your water to be or whether you’ll be using a solar cover.

Keep in mind that the bigger the pool, the bigger the electric pool heater needs to be. Electric heaters measure their power using British Thermal Units (BTU), so refer to that measurement when buying yours.

How Much Electricity Does an Electric Pool Heater Use?

On average, electric pool heaters use 5 kilowatts per hour, for every 100,000 BTU. You should check your electricity bill to see how much that would cost in your location.

Tip: If you add a solar cover to your pool while you use the heater, you can reduce the time taken to heat the water. That way, you’ll be saving energy and time, making your heating experience a lot more efficient.

Conclusion

Pool heaters can be a lifesaver in cold climates or during the winter. By heating the water, you can enjoy swimming and relaxing all day and night. The power your heater will need will depend entirely on the size of your pool and whether it is indoors or outdoors.

The overall best electric pool heater for inground pools is the Bestway Flowclear Swimming Pool Water Heater. It can effectively warm larger pool areas within a few hours and is compatible with pool filter systems.
