Electric heat pump

An electric heat pump sucks in the environmental air from outside and warms it up. The warmer the environment is, the warmer the water will become. The inhabitants of warmer countries tend to prefer an electric heat pump more than the others.

If the temperature in your area is no less than 40-50 Degree Celsius, it is a good choice for you. On the other hand, areas with temperatures below 40-50 degrees Celsius are not competent for this pump. The pump is inefficient for those areas. 

Gas heaters

On the contrary, Gas heaters work using natural gas or propane for keeping the water ambiance warm. If you’re searching for something that can turn the pool water warm in no time, a gas heater would be a perfect choice. 

The most vital point about gas heaters is their controlling power. You can control the temperature of your pool according to your desire with a gas pump. The desired temperature will provide spa-like comfort l level all over the year.

Pool Heat Pump vs. Gas Heater: Basic Differences


The expense of an electric heat pump varies depending on whether it’s in-ground or above-ground. The in-ground electric heat pumps cost nearly $2,500-$5,000, which is much more expensive than gas heaters. Contrarily, the above-ground electric heat pumps cost $1,700-$2,500.

The operating expense of Electric heat pumps is significantly less than gas heaters. The annual cost on average is $8,00-$1,000. And you can cut down a generous amount of expense if you cover the pool while not in use.

On the other hand, the cost of pool gas heaters is quite affordable. Most of the households in the USA choose gas pool heaters because of their low cost. Besides, the maintenance and availability are comparatively reasonable. 

The gas heater operating cost will be around $14.02 to 1 million Btu in the USA. The exact costing will vary according to your maintenance and use. If you take good care of the gas pump, the efficiency and reliability will increase. 

The maintenance cost is lower than the electric heat pump. The annual savings by a heater is around $420. 


Electric heat pumps work well, only if you’re able to choose the right size. The experts categorize electric heat pumps based on horsepower (HP) and British Thermal Unit (Btu) output.

If you ask me about their standard size, the answer is 3.5 HP/75,000 Btu, five HP/100,000 Btu, and six HP/125,000 Btu. I suggest you hire a professional if you’re confused about which size is the right one. 

When it comes to gas heaters, pool sizing is quite important to control the temperature. The gas swimming pool heaters are comparatively bulkier. Heater pumps carry the extra gas pumps and extra equipment.

If you ask about the recommended size, it will depend on the pool size. If your pool size is around 16” x 32”, the heater size will be 250,000 Btu, 18” x 36” of pool size will require 325,000 Btu, and 20” x 40” size swimming pool will require around 400,000 BTU gas heat pump. 


No matter how well-built the heat pump is, all will go in vain if the machine isn’t efficient enough. Even though measuring efficiency is complex, the experts can do it well.

The coefficient of performance (COP), ranging from 3-7, is the key to measuring efficiency. The higher the COP, the better the efficiency will stand.

Never forget to research the efficiency of the heat pump you’re about to purchase. You can also check out the reviews of the product for assurance. Even if the efficiency has good ratings, this feature alone isn’t enough.

On the contrary, Gas heaters’ performance level extends from 75,000 Btu to 450,000 Btu. Before, people considered gas pumps to be lower in serving efficient performance.

However, now gas pool heaters are showing great success and efficiency with their performance. On today’s date, you’ll get gas pumps serving around 95% performance efficiency.

If you compare the run time, gas heaters seem to serve better and reasonable run time with the fuel tank.
