Swimming Pool Heater vs. Heat Pump

If you’re looking to extend the pool season, heaters and heat pumps are among the best options. But what makes one different from the other? To ensure an educated decision, we’ll help you understand the main features of a swimming pool heater vs. heat pump.

Pool Heaters

Swimming pool heaters are the most popular option when it comes to heating your pool. Heaters utilize natural gas, propane, or electricity to heat water returning back into your pool. They have a lower upfront cost and raise water temperatures quickly. Although heaters have a lower upfront cost than heat pumps, they do require the ongoing expense of propane or natural gas. This ongoing cost of operation generally exceeds the expense of running a heat pump.

Depending on the type of fuel used (propane or natural gas) and the geographic location of your pool, the cost to heat your pool can range from about $3.00 to $9.00 per hour. Natural gas heaters typically cost a few dollars less per hour vs. propane heaters. Depending on where you live, natural gas can also cost up to 85% less than propane gas. On the flip side, propane might be the most readily available fuel source in your region.

An electric pool heater is another great option if propane or natural gas won't work for your pool. Electric heaters aren't quite as efficient as other styles of heaters, so these are typically reserved for smaller pools, indoor pools, or spas and hot tubs. Electric heaters will increase your monthly electric bill, but they're a dependable way to heat any pool.

PROS:

  • Lower upfront cost.
  • Heats pool water quickly.
  • Works in any temperature.
  • Easily installed into plumbed gas line from your home.

CONS:

  • Higher utility costs.
  • More moving parts compared to heat pumps.

Heat Pumps

Heat pumps are becoming increasingly popular for pool owners. They use the ambient air surrounding the unit to heat your pool. The air passes over an evaporator coil, and the heated refrigerant transfers the heat to the water returning back into your pool. This process does not require natural gas or propane resources, which lowers running utility costs drastically. Heat pumps cost about $0.63 an hour to run on electricity; a fraction of the cost of propane or natural gas.

Although running costs are low, heat pumps do have a slight disadvantage. Since heat pumps use the surrounding (ambient) air around the unit, they only work well when temperatures are higher than 50 degrees Fahrenheit. When temperatures drop below 50 degrees, heat pumps lose the ability to effectively heat your pool water.

Conclusion

Both heaters and heat pumps are a great solution for pool owners looking for effective ways to heat their pool water. The main deciding factors between a pool heater vs. a heat pump will be your location, budget, and heating needs. If you live in a colder climate and want to extend the pool season for as long as possible, you'll probably lean towards a natural gas, propane, or electric pool heater. However, if you want something that will save you money in the long run, and you live in a climate that does not drop below 50 degrees often, a heat pump might be the best option.
