How Does a Pool Heater Work? 

Swimming Pool heaters can run either on solar power, gas, or electricity. The pool heat pump circulates water from the pool into the heat exchanger.

First, the water goes through a filter and then into a heating chamber. Heat is extracted from the heat source and then transferred to the water as it passes through the chamber. and if you are looking for the cheapest and most cost efficient way to heat a swimming pool we have wrote an awesome article for you.

The water is then sent back to the Pool already heated.

Types of Heaters 

There are four main types to consider. Here’s what you need to know about them all.

  • check
    Electric Resistance: An electric resistance unit is the best for small therapy pool and portable pool even during cold months because it doesn’t depend on air temperature. It, however, consumes a great deal of electricity. It is the most compact heater with some models occupying less than 12 feet.An electric water heater is more affordable than other types. However, they are expensive to install and not a very energy efficient machine.
  • check
    Gas Heaters: Propane gas heaters were popular a couple of decades ago. But because of unpredictable gas prices, more and more people are choosing more efficient heating options. Propane unitss are incredibly affordable and can be used for warming up the pool quickly. But they come with high operating costs and aren’t eco-friendly as they provide high levels of gas emissions.
  • check
    Heat Pump: Like an electric unit, heat pumps use electricity to operate. They can either be air-source or water-source pumps. They’re desired for their energy efficiency. Their monthly operating costs are quite low, costing as little as $50 a month. These heaters are also dependable, lasting as much as 20 years. Heat pumps don’t produce harmful gasses and use renewable energy, making them great for the environment.

Conclusion and Final Recommendation
