Historically, gas warmers were used for many years and with the aid of many people. Moreover, today, thanks to the ever-progressing technology, we’ve clever gas pool heaters. Such a lot of these natural fuel heaters are pilotless with digital ignition, fan-assisted combustion, and low-Nox emissions.

Gas heaters burn either natural gasoline or propane to create heat. The mechanism is simple — fuel burns within a combustion chamber with a lot of copper coils. Because it burns, water passes by way of the coils and heats.

These heaters save you meaningful energy and money.


  • Inexpensive.
  • Heats the pool water quickly.
  • Works independently of air temperature.
  • Great for any size or any design of swimming pool.
  • Emits low emissions.


  • Expensive to operate.
  • Uses gas or propane — both high-priced alternatives.
  • Not an green option.
  • Causes air pollution.
  • Not very power efficient (COP 0.80 and 0.85)
  • Has a short lifespan of approximately 5 years.

2. Pool warmth pumps

While air-source heat pumps move heat from the air, water-source aka geothermal warmness pumps transfer warmness from the water. Due to their energy-efficiency, these heat exchangers are rapidly growing in popularity.


  • Eco-friendly: uses a renewable power source.
  • Is power efficient with COP of 5-6
  • There are no emissions, reasons no pollution.
  • Cheap to run.
  • Has a lifespan of 10-20 years.


  • Expensive to buy.
  • Heats pool water slowly.
  • Requires continuous electricity provide with 220V outlet.
  • Doesn’t paintings good in colder temperatures.

3. Photo voltaic swimming pool heaters

Cost: A photo voltaic pool heating method usually fees among $3,000 and $4,000 to purchase and install.

Here’s a heater that uses the sun’s power to deliver a excessive output photo voltaic heating system. The science is straightforward — the photo voltaic panels collect warmness from the sun. Then, the swimming pool pump pushes water by way of the solar panels. As the water passes by means of the photo voltaic panels, it heats.

For cloudy and wet days, numerous people use auxiliary heaters anyway the solar pool heater.


  • Eco-friendly alternative for heating a pool.

  • Heats water very slowly.
  • The photo voltaic panels make your backyard look messy.

4. Electrical resistance heaters

Cost: So much electric resistance warmers areavailable for only $2,000

These resistance warmers use electric currents to create heat. A current is applied to the resistor positioned within the unit. As a result, the resistor heats. Water then washes over the resistor and heats — inflicting the resistor to cool.

As they require huge quantities of electricity, such warmers aren’t splendid for large-sized pools. They’re usually used to heat small, portable spas and therapy pools.


  • Inexpensive to buy
  • Doesn’t count much on air temperature.
  • Environment-friendly.
  • Doesn’t cause air pollution.
  • Perfect as spa heaters.
