A Guide to Choosing a Heater for Your Pool

Keeping your pool heated might not seem like the best idea for the summer, but with a heater you can keep it nice and warm even as the weather cools down.

Keeping your pool heated might not seem like the best idea for the summer, but with a heater you can keep it nice and warm even as the weather cools down.  Now, you might be wondering, which type of pool heater is right for you? We’ve put together this helpful guide to help you select the heater you would like best for your swimming pool.

Electric Heaters

As the name implies, electric heaters use electricity to generate heat.  Currents are run through the resistor, a critical component inside the heater unit itself. The water flows over the resistor, which heats the water up while cooling the resistor down. However, these heaters demand a large, steady supply of electricity in order to function properly. So they’re mainly used for heating small spas and for therapy pools.

Pros of Electric Heaters:

  • Affordable
  • Do not depend on temperature of surrounding air

Cons of Electric Heaters:

  • Installation can be expensive
  • Not energy efficient

Gas Heaters

Gas heaters need natural gas or propane as fuel. The gas burns inside what is known as a combustion chamber. The combustion chamber contains copper coils, which are the essential component of these heaters. While the gas is burning, water flows through the coils and heats up. Gas heaters have long been the most popular model of swimming pool heaters. But given the high price of gas and advances in technology, such as the heat pump, the once-soaring popularity of gas heaters is declining.

Pros of Gas Heaters:

  • Affordable
  • Rapidly heats the water

Cons of Gas Heaters:

  • Expected lifespan around five years
  • Can create air pollution

Heat Pumps

Like electric heaters, heat pumps also use electricity. However, there are two main types of heat pumps. Air-source heat pumps draw heat from the surrounding air, while water-source heat pumps draw heat from nearby water. Due their tremendous energy-efficiency, heat pumps have become extremely popular as of late.

Pros of Heat Pumps:

  • Relatively low operating costs
  • Greatly energy-efficient
  • The water-source heat pumps do not depend on the air temperature
  • Can last anywhere from 10-20 years
  • Eco-friendly

Cons of Heat Pumps:

  • Very expensive to buy
  • Air-source heat pumps do depend on the air temperature
  • Heats the water slowly

Solar-Powered Heaters

Solar-powered heaters work in tandem with solar panels to heat up your swimming pool. Sunlight powers the solar panels, which then heat up the water as it is pumped through the panels.  Since solar-powered heaters need sunlight to operate, most users will have backup heaters to use at night or when it is cloudy outside.

Pros of Solar-Powered Heaters:

  • Low operating costs
  • Highly energy-efficient
  • Will last anywhere from 15-20 years
  • Eco-friendly

Cons of Solar-Powered Heaters:

  • Astronomically expensive
  • Reliant on the sun; can’t operate during the night, and runs less efficiently in cloudy weather
  • Heats water slowly
  • Installations on roof or lawn can be unsightly
