If you are planning on using your pool for over four months a year depending on the climatic conditions of your residence, then you will need a pool heater. The type of heater to be installed will be determined by several factors one of them being a pool heater cost.

What Is A Pool Heater?

A pool heater is basically a gadget that is specifically designed to allow you to heat your pool so you can enjoy it any time of the day. This can be at night where the temperatures are not favorable. However, with a pool heater, you can swim at 3 am with very little discomfort as the temperature in your pool will be favorable.

Why Should Heat Your Pool

If you like swimming and spending most of the time floating on water, then a pool heater is not a luxury item but a basic good you must have.  Children are particularly disappointed when they cannot spend quality time in the water because it is not favorable for them. A pool heater bought at the right pool heater cost ensures the fun does not stop for at least 6 months.

Different Pool Heaters And Pool Heater Costs

There are four main types of pool heaters that come in different pool heater costs. They are:

  • Electric resistance heaters
  • Gas heaters
  • Solar heaters
  • Heat pump heaters

Electric Resistance Heaters

Just as the name suggests, this heater heats your pool by using electric currents on your resistor. When the resistor is subjected to electric currents, it heats. As it heats, water flows over the resistor cooling it and warming the water.  Electric resistance heaters require large amounts of electricity to heat your pool. This makes it unsuitable for large swimming pools as the electricity bills will be too much.

How Much Does This Pool Heater Cost?

To purchase an electric resistance heater for your spa and therapy pool, you should be prepared to part with around $2,000.

Advantages Of This Heater

  • Unlike other heaters that depend on external factors such as air to heat, this heater does not depend on air temperature to function optimally. It works well during winter.
  • This heater is environmentally friendly; it is not emitting any air pollution.

Disadvantages Of This Heater

The main disadvantage of this heater is the operating cost. You will pay an arm and a leg to install it. This is because it requires large-amperage circuit breakers and heavy-duty wiring. Too much energy is used for heating the pool, this makes this pool heater energy inefficient

Gas Heaters

Gas heaters use natural gas or propane to heat your pool. Unlike other heaters, it does not depend on external climatic conditions to work. This is because the gas pool heater uses a combustion chamber to heat the fuel required to heat your pool.  Once the fuel is heat, the water in your pool will then flow through copper coils and in the process cooling the coil at the same time warming the water.

Gas has always been used to heat pools. However, its popularity is fading because of the ever-increasing gas prices.

How Much Does A Gas Heater Cost

At the moment, propane costs around $3 per gallon. This means that to maintain a pool in Central Florida at a constant temperature of 80?F per year, it will cost you around $4,000. Keep in mind that this pool measure 14 by 28. Compared to the Electrical resistance heater, the pool heater cost is around $1500.

Advantages Of Gas Heaters

  • This is cheaper compared to the electric resistance heater
  • It does not depend on external weather factors such as external air temperatures to operate
  • It quickly heats the pool

Disadvantages Of A Gas Heater

  • It is not energy efficient as it has a COP of 0.80 to 0.85
  • Since you part with around $300 - $500 in monthly operating costs, it is expensive to maintain this heater.
  • The biggest disadvantage if this heater is that it emits air pollution and hence not environmentally friendly.A lifespan of 5 years is not ideal

Solar Heaters

Solar heaters use the sun's heat to heat your pool especially if you are in the northern climate regions. The pool pump circulates the water in your pool through solar panels are mainly on top of your roof. Since solar heaters depend on the sun to heat your pool, you might have to rely on auxiliary heaters during cloudy days.

Cost Of Purchasing A Solar Heater

Contrary to popular belief, a solar heater is not cheap. This is because the pool heater cost for this item is around $4000 - $7000. This is too high compared to other heaters in the market. This is however worth it as you will use solar power; which is plentiful throughout the year in most states. It is also free and inexhaustible.



  • The main advantage of Using solar is that you have no unforeseen operating costs. This is because it has a long lifespan and the sun is free
  • Solar heaters come with a lifespan of between 15-20 years, hence sustainable and economically viable
  • Unlike other heaters, it is environmentally friendly as it produces no air pollution
  • If you are in a state where the sun is always shining, then you will have warm water throughout the year

Disadvantages Of Using A Solar Heater

  • This is an expensive gadget to purchase as you part with around $4000 - $7000 to have it installed.
  • Operates inefficiently in cloudy weather
  • Only suitable if you are in a state with abundant sunshine
  • Solar heaters make your roof unattractive because of the installation
  • The heating process is slow
  • You will incur pumping costs to pump the water to the roof so it can be warmed by the solar heater

Heat Pumps

There are two types of heat pumps;

  • Air-source heat pumps
  • Water-source heat pumps

An air source heat pump transfers heat from the environment into your swimming pool while a water-source heat pump {also known as geothermal heat pump} transfers heat from a water source into your swimming pool.

Costs Of Purchasing A Heat Pump

Purchasing a heat pump whether a geothermal heat pump or an air heat pump is not cheap. Be prepared to part with around $2,000 - $4000.


Advantages Of Heat Pumps

  • Heat pumps are very economical to operate as they have an operating expense of around $50-150.
  • They boast a lifespan of about 10-20 years depending on maintenance
  • They have a COP of between 5 and 6 hence energy efficient
  • Since they emit no air pollution, they are environmentally friendly
  • Water source air pumps do not depend on the air temperature

Disadvantages Of Heat Pumps

  • They are expensive since you pay around $2,000 - $4000 to own one
  • Though efficient, they heat the pool slowly
  • Air-source heat pumps depend on the air temperature for them to work efficiently

How To Choose The Right Heater

For many pool owners, this may be a difficult and challenging thing to do. Many factors such as the location you are in, the pool heater cost, usage, and maintenance budget all determine which is best for you. 

The Location

The Cost


Maintenance and Budget
