How Much Does a Pool Heater Cost to Install? [2026 Data]

In 2026, the national average pool heater installation cost is $3,094, based on data from 1,019 verified projects by Angi Pros. Most homeowners pay between $1,864 and $4,348, with the spread driven by heater type, pool size, and the complexity of gas or electrical hookups. If you're eyeing a large solar system or need new utility lines run, costs can climb toward the higher end of the range.

Pool Heater Cost Factors: What Determines the Price?

Pool heater installation costs vary based on several factors, with pool size and available utilities being the most significant drivers. Even when utilities are already on your property, most homeowners still need to run new lines to connect the heater. Understanding these variables upfront will help you build a realistic budget for your project.

Pool Heater Type

The type of pool heater you choose will largely determine your total project cost, with installed prices ranging from $1,000 to $9,500. Different heaters run on different energy sources, so the type you select affects both your upfront installation cost and your ongoing monthly utility bill. A less expensive heater to install can sometimes cost significantly more to operate over time. The table below covers each pool heater type and its impact on overall project cost:

Gas or Propane Pool Heater

This is the most common type of heater design for both in-ground and aboveground pools. Expect to pay between $1,000 and $4,500 for the heater itself and $500 to $1,500 for labor.

Gas heaters typically connect to a preexisting gas line, while propane heaters require a standalone tank. The monthly energy cost when using one of these heaters will be high, though they’re considered inexpensive to source and install.

Installing a heater during pool construction could save you some money. Talk to your contractor as you calculate the cost of building an aboveground pool.

Electric Resistance Pool Heater

Electric resistance pool heaters are relatively inexpensive to install but require a large amount of electricity for use. Expect to pay $500 to $5,000 for the heater and $500 to $1,000 for labor. These heaters use resistance coils to heat the water and work best in small pools and in climates above 55 degrees Fahrenheit.

Solar Pool Heater

Solar pool heaters cost $2,000 to $7,500 for the unit itself and an additional $500 to $2,000 for labor. Though they have a higher upfront cost than gas heaters, your energy bill will be virtually nonexistent, especially when you pair them with a solar pool cover.

This is the most cost-effective solution to heating a pool, but you can only use a solar pool heater in areas that receive consistent direct sunlight. If you live in warmer states like Florida or Arizona, this could be a good choice, though the same cannot be said about colder states like Minnesota and Colorado.

Pool Heat Pump

This type of pool heater draws hot air from the atmosphere to warm the water. The heat pump itself will cost $2,000 to $6,500, with labor costing $500 to $1,000.  The upfront costs are higher than those of some other types of pool heaters, as heat pumps require a dedicated electrical circuit to operate.

These heaters are relatively energy-efficient, which is great for your utility bill, but they heat more slowly than gas models.

Pool Type

Installing an above-ground or hot tub pool heater costs less than an in-ground system because all components sit at surface level. In-ground pool heaters incur higher labor and material costs due to the extensive trenching required to run and bury the plumbing and electrical lines.

Pool Size

Choosing the right size pool heater is one of the most important decisions you’ll make during this project. A heater that’s too small will work harder than necessary to keep up with your pool's volume, leading to premature wear and eventual repair or replacement costs. Speak with a pool heater installer near you to determine the correct size before you buy. The table below shows estimated BTU requirements and pool heater installation costs by pool volume:

Location

Where you live affects your pool heater cost in two key ways: utility availability and climate. In rural areas without accessible gas or electrical lines, propane may be your only viable fuel option. Homeowners in warm, sunny climates can opt for less powerful or solar-based heaters, which reduce both installation and operating costs. Climate also determines how hard your heater has to work, which directly impacts long-term energy expenses.

Hookup Installation

Most homeowners will need to install utility lines to operate their new pool heater, and the type of heater you choose determines which lines are required. Gas, water, or electrical circuits may all be necessary depending on your setup. If you’re unsure what your installation will require, talk to your local pool technician before purchasing a heater. The table below shows pool heater hookup costs by utility type:

Labor

Labor costs for pool heater installation depend on the amount of work required and the type of contractor performing the installation. Most qualified electricians cost $50 to $100 per hour, while the cost of a plumber ranges from $45 to $200 per hour. Projects that require both electrical and plumbing work will naturally carry higher total labor costs.

Removing the Old Heater

Replacing an existing pool heater adds a small removal fee of $25 to $50 to your total project cost. Most pros roll this charge into the overall installation estimate rather than billing it separately. Some contractors will waive the removal fee entirely when you purchase and install a brand-new unit through them.

Permits

Permits for pool heater installation are not always required, but they’re mandatory for roof-mounted solar heaters and any project that involves running a new gas line, with costs ranging from $100 to $500 depending on your region. Your pool heater installer will confirm whether a permit is needed during the initial consultation. Requirements and fees vary by location, so it is worth asking about this early in the planning process.

Pool Heater Ongoing Costs: What to Budget For

A pool heater adds to the cost of running a pool, particularly if you choose a propane or electric resistance model, which carries the highest monthly energy costs. Beyond energy, pool heaters also require regular upkeep, maintenance, and winterization in colder climates. Factoring in these ongoing expenses from the start will help you choose the heater type that best fits your long-term budget.

Energy Costs

Monthly energy costs are among the most significant ongoing expenses for pool heater owners, and the type of heater you choose determines how large that bill will be. Gas and propane models tend to cost the most to operate ($200 to $850 per month), while solar heaters have the lowest monthly energy impact at $0 to $10 per month. The table below shows estimated monthly heating costs by pool heater type:

How to Prolong the Life of Your Pool Heater

There are a few ways you can prolong the lifespan of your pool heater and keep monthly costs down.

Maintenance and Repairs

Regular maintenance and timely repairs are essential to keeping your pool heater running efficiently and extending its lifespan. Basic upkeep includes clearing debris around the unit, checking for rodent activity, and maintaining proper water pH. Properly winterizing the heater each season is equally important, especially in colder climates. A pool installation company can handle routine maintenance checks and complete any necessary repairs on your behalf.

Winterization

While properly winterizing your pool heater can add to your heated pool cost, it will also keep it in good condition longer and make it easier to operate each summer. Proper winterization includes:

• Following the manufacturer's instructions for winterization

• Removing water from the pool heater, pipes, pump, and filter to prevent it from freezing and damaging these elements

• Closing gas valves for a gas pool heater

• Opening winterization ports or drain cocks

• Turning off electricity to the pool and heat pump

• Removing drain plugs

• Checking heat pump throughout the winter to remove any debris and check for damage from rodents

You can also consult a pool maintenance professional to ensure the pool heater is winterized correctly.

Pool Heating Alternatives

Pool heating alternatives let you run your heater less often, reducing both energy costs and wear on the unit. The right option depends on your climate, budget, and how much heat retention you need:

• Pool cover: A simple pool cover costs between $650 and $2,200 to buy and install. It will help retain heat and should reduce energy costs by 50% to 90%. 

• Solar blanket: Installing a solar blanket will cost between $50 and $500. These coverings tend to feature a multitude of air bubbles on the exterior that trap heat released via direct sunlight. The blanket transfers this heat to the pool's water. If you live in a sun-drenched area, a solar blanket can help reduce monthly energy costs by up to 75%.

• Pool enclosure: You can expect to save oodles on your monthly energy bill with a pool enclosure, but installation costs $5,000 to $14,000. Building a pool enclosure can be a fantastic choice for colder climates, as it essentially turns the pool's location into another room in the house. 

Pool Heater Pro Costs: What Homeowners Pay

Installing a pool heater often requires running new electrical, water, or gas lines, and is a job best left to a local pool heater pro. Some pool heaters also have installation requirements that necessitate hiring an electrician or plumber (or both). Labor rates depend on the type of professional, but you can rest assured knowing your pool heater was installed properly.

Here’s why it’s ideal to hire a pool heater installation pro

A pro will do the following to ensure the pool heater is installed the right way:

• Pool techs can recommend the right size for your pool heater based on the size of your pool.

• They’ll assess the utility lines you currently have to determine pool heater options.

• Electricians can safely run electrical lines and hook them up to the pool heater.

• Plumbers can run water lines and gas lines to ensure a proper connection.

• Pool heater installers understand permitting requirements and help obtain any necessary permits.

If you want to DIY pool heater installation

Relying on a qualified professional is the best way to make sure the pool heater is installed properly, but there are a few things you can do to make the process more efficient and cost-effective:

• Ensure the existing heater or the location for the new heater is easily accessible by removing patio furniture, toys, or decorations.

• Clear the area of shrubs or trees. 

• Have the utility company mark the location of existing utility lines. 

How to Save on Pool Heater Installation Costs 

Many factors of pool heater installation costs are fixed, meaning there’s not much you can do to reduce expenses. In addition to the cost of the heater itself, you likely cannot skip out on the cost of professional labor. That said, there are ways to shave money off the final price tag. It just takes some strategic planning.

1. Wait Until Autumn to Buy Your Heater

Autumn is the best time to buy a pool heater if you want a deal. Most homeowners work on their pool in the spring, so it is ready when the weather gets warm enough to swim. By the time autumn rolls around, pool companies are wrapping up their busy season and may offer sales and discounts to drum up additional work. 

2. Choose a High Efficiency Heater for Long-Term Savings

High-efficiency heaters cost more upfront, but if you use your pool heater often, you could actually end up saving money in the long run. For example, heat pumps can save you anywhere from $950 to $4,800 per year in energy costs compared to gas or electric resistance pool heaters. Solar heaters save even more since they cost less than $120 per year to run. 

3. Choose a Heater That Works With Existing Utility Lines

Most homeowners need to install some utility lines when they put in a heater, but you can save thousands by working with what you already have. If there is a readily available gas line, go with a gas heater. If you already have an outdoor electrical circuit, go with an electric resistance heater or heat pump.

Keep in mind that propane heaters are sometimes an exception. Depending on the situation, it could cost up to $850 per month to run this type of heater. In this case, you may actually save money by installing a utility hookup, so run the numbers before you buy.

4. Add a Heater Onto a Larger Job

If you are building a new pool, do not wait to install a heater. You can save money if you do both jobs at the same time. Often, grouping together smaller contracting jobs saves cash compared to doing each job individually.
