A swimming pool makes a great addition to your outdoor space. It looks good and offers a place for exercise, relaxation, and play. Installing a swimming pool heater is one way to make sure you are able to utilize your pool for as long as possible throughout the year. Because there are multiple kinds of heaters, the cost to install a swimming pool heater can vary greatly and depend on the type of heater you choose.

On average, most homeowners spend between $1,530 and $3,740 when installing a swimming pool heater. Running the heater can cost an additional $100 to $600 per month, but again, that depends on many factors. The type of heater you install, the amount of energy it takes to run, and its location will all influence your total cost. Your first step should be to contact a professional who can help you determine what kind of heater will work best for your pool and for your local climate.

Cost Factors

The type of heater you choose can greatly influence your cost, both up front and over time. Average purchase costs may fall within the following ranges:

  • Electric resistance heater: under $2,000
  • Gas heater: $1,500 to $2,500
  • Heat pump: $2,500 to $3,500
  • Solar panels: $1,500 to $2,000

There is also a variety of outside factors that influence the cost of your heater, including:

  • Above-ground or in-ground pool
  • Size of your pool
  • Pre-existing hookups
  • Size of the heater you need

After you purchase your unit, you need to decide whether you want to install it yourself or have it professionally installed. In most cases, it is a good idea to have a professional do this job for you. Expect the following installation costs:

  • Gas heater: $500 to $1,500
  • Heat pump: $500 to $1,000
  • Solar panels: $500 to $1,000

If you are switching out an old or broken unit and already have the necessary hookups for a heater, your installation cost may be less.

Cost to Run a Pool Heater

Because each pool heater works differently, the cost to run per month varies. Expect these costs with the following heaters:

Type of Heater

Cost Per Month

Electric Resistance

$500 to $600

Gas Heater

$200 to $400

Heat Pump

$100 to $200

Solar Heater

$0

These additional factors can also influence your monthly cost:

  • The size of your pool and your heater
  • Current cost of gas or electricity
  • Average daily temperatures in your area
  • Your desired water temperature
  • Extreme weather, like heavy rains or high winds
  • Whether your pool is covered or uncovered

Your choice of pool heater may also depend on your climate. If you live in a cooler climate, investing in a reliable pool heater can be worth it, as it can allow you to get as much use out of your pool as possible. Those in warm, sunny climates may find that solar panels provide the right amount of heat needed without the burden of high monthly costs.

Types of Heaters

Electric Resistance Heaters

An electric resistance heater uses electricity to create heat. As water washes over the resistor unit, it heats the pool. These types of heaters are inefficient for large swimming pools, but are often a good option for smaller spas or therapy pools.

Advantages and Disadvantages of Electric Resistance Heaters

Advantages

Disadvantages

Don't emit air pollution


Inexpensive to purchase


Don't rely on outside air temperature

Require very large amounts of electricity


Expensive to operate


Expensive to install


Not energy efficient

Gas Heaters

The most common type of pool heater, the gas heater uses either natural gas or propane to heat the water. If you have a natural gas line, the heater can hook up to the existing line; if not, you can opt to use a propane tank that is mounted above or below the ground. Installation involves PVC plumbing, electrical wiring, and venting.

Advantages and Disadvantages of Gas Heaters

Advantages

Disadvantages

Low installation cost


Work quickly


A thermostat gives you complete control over temperature

Easy to forget to turn these heaters off


Expensive monthly cost

Heat Pumps

A heat pump extracts heat from the air, which means it uses less energy than an electric or gas heater. It does require a dedicated breaker to supply power to the unit, which may mean a higher upfront cost because this element needs to be professionally installed. Heat pumps may also be able to add a couple weeks to either end of your pool season when temperatures are chillier, and despite the large circuits that run them, they are quite efficient. The cost to install a pool heat pump is comparable to a gas model, so what you end up paying generally depends on which type you prefer.

Advantages and Disadvantages of Heat Pumps

Advantages

Disadvantages

Cheaper to maintain than gas heaters


Clean


Economical


Cost less per month to run

Slower to heat pools than gas models

Solar Heaters

A solar heater is considered the most cost-effective method for heating a swimming pool.

However, it is the least dependable. This heater uses solar panels to warm the water in your pool, and the water then circulates using your existing pool pump. In order for this type of heater to be effective, it is recommended that you have enough solar panels to equal at least half of your pool's square footage. Solar panels are efficient options, but they will only heat your pool when the outside temperature is warmer than the pool water. Many pool owners choose to use them in conjunction with a backup heating system.

Advantages and Disadvantages of Solar Heaters

Advantages

Disadvantages

Little to no cost to run



Last 15 to 20 years


Very low maintenance


Environmentally friendly


Energy efficient

Won't work if they don't get enough sunlight


Not a good choice for pools in shaded areas


Heat the pool water slowly


Panels can be unattractive


Expensive to purchase

Keeping the Pool Warm

When you use a heater, it is important to conserve as much of your pool's warmth as possible to keep heating costs down. A pool cover, or solar blanket, is a low-cost way to ensure that your heater works efficiently. The cover is made of air-filled bubbles that attract sunlight to heat the pool. Keeping the pool covered at night or during days when it isn't in use helps the water stay warm. Using one of these covers requires no operating cost and can increase the pool's temperature by 10 degrees. Using a solar reel is an easy way to take the blanket off and put it back on when desired.
