How Pool Heat Pumps Work

Pool heat pumps run by attracting warm air and converting it to gas using electricity. This means that the mechanism doesn’t generate any of its heat. They have a fan that attracts air that has been warmed by the sun. It goes through coils and then is transformed into gas. It then passes through a compressor and then a condenser. The pool pump will pump the water into the filter and then through the heater. Here the water is heated three to five degrees and then pumped back into the pool.

Sizing The Pool Heat Pump

Choosing the right size for your pool heat pump is important. Pools measure their power in British Thermal Units (BTUs). One BTU is responsible for heating one pound of water by one degree Fahrenheit. The conversion on this is 8.33 pounds of water per gallon. So if you know how many gallons your pool has, you are off to a great start. From here you can do the calculations. Most of the time, you will want to be able to heat a pool by 20 degrees over 24 hours. You will have to refer to the manufacturer’s instructions, but overestimating your BTUs is better because you have to account for outside variables such as heat you will lose through evaporation.

Pros and Cons of Pool Heat Pump

  • Less cost off the bat

  • Good for cooler climates
  • Cheaper to run than a pool heater
  • Not that complicated to install
  • Environmentally friendly
  • Less popular than pool heaters

Pool Heat Pump Winterizing

The main thing that you need to do when winterizing your pool heat pump is to drain it of all water. Additionally, just make sure that rodents don’t make a nest in it and that no needles are clogging it up. You should also invest in a pool heater cover to make sure that you shield the pool heat pump from the elements.

How to Choose a Heat Pump?

When it comes to choosing a heat pump, you will have to consider several factors. For one, you will have to know your budget. Additionally, you will need to determine whether you want a heat pump with or without ducts. Next, you will need to know if you want a dual-fuel pump. If you live in an area that has higher electrical costs, then you should consider dual-fuel. Finally, deciding on the type of thermostat you want will be your final choice.

Can a Pool Heat Pump Be Used For Any Pool?

A pool heat pump is like a reverse air conditioner for your pool. If you live in a colder area, it doesn’t make sense to get a pool heat pump. It’s better to get a pool heat pump if you live in a warm climate as it relies on attracting warm air. Additionally, if your pool is complex and has many areas, then you should opt for a heater. A pool heat pump works well on smaller pools with simple heating needs.

How Do you Determine the Right Size Pool Heat Pump for Your Pool?

When looking for the right size of the pool heat pump for your pool, you will need to look up a chart. There are many charts online and in a manufacturer’s instruction list that state exactly what size you need for your pool. Knowing your measurements for the pool and the amount of gallons that your pool holds is the first step.

What’s Better, a Pool Heat Pump or a Gas Pool Heater?

It’s hard to say offhand which is better, a pool heat pump or a gas pool heater. Those who live in cold climates with a short unpredictable swimming season should get a pool heater. Those who don’t need a lot of heating in their areas, such as someone from California or Florida, will want to consider a pool heat pump. It boils down to your climate as to whether a pool heat pump will work for you.
