Highlights
Electric heaters are more expensive to repair than natural gas, but they often last 5 years longer.
Solar heaters are cost-effective to repair and have a lifespan of up to 25 years, but they take longer to heat up your pool.
If the repair is 50% or more of the cost of a new heater, swap it out for the best ROI.
The best way to avoid costly repairs is to perform monthly maintenance, which costs a few hundred dollars per year—depending on the type and size of the pool.
Taking a dive with the Polar Bear Club was never your idea of a good time—that’s why you’ve relied on your trusty pool heater to keep the water nice and toasty.

You may be able to diagnose pool heater issues by troubleshooting or checking error codes where applicable. Unfortunately, though, some problems aren’t fixable and will require you to invest in the cost of a replacement heater. If you’re stumped or just not comfortable working on things yourself, it’s wise to bring in a pro. Here’s a breakdown of what you might pay.
Type of Pool Heater
The type of pool heater greatly affects the costs of repair. Electric pool heater costs are typically the highest, though costs vary. In general, you can expect to pay the most for electric pool heater repairs and the least for solar, with natural gas heaters falling somewhere in between.
| Pool Heater Type | Repair Cost Range | Description |
|---|---|---|
| Electric | $200–$1,200 | Great for consistent heating, slow to come to temp |
| Natural gas | $150–$750 | Faster heating, less costly repair |
| Solar | $50–$400 | Easiest maintenance and repair, slower heating |
Saltwater vs. Chlorine Pools
Maintaining and repairing saltwater pool heaters can cost up to 50 percent more than chlorine pool heaters. A saltwater pool requires a saltwater-specific heater with corrosion-resistant parts. A non-saltwater heater installed in a saltwater pool will break down more often and may require replacement fairly quickly because of accumulated damage.
| Pool Type | Repair Costs |
|---|---|
| Saltwater | $500–$1,500 |
| Chlorine | $165–$790 |
Labor
Hiring a professional to handle pool heater repairs can cost an average of $80 to $120 per hour. Diagnosing issues on your own can be tricky, so it’s often worthwhile to seek out the knowledge of a pro.
Materials
Replacement parts can cost anywhere from $20 to $600. The necessary parts (and prices) will vary based on the type of pool heater, as well as its make and model.
Warranties
Read through the heater’s warranty because the services and labor covered can vary.
| Heater Type | Average Warranty in Years |
|---|---|
| Electric | 1–10 |
| Solar | 5–12 |
| Gas | 2–5 |
Pool Heater Repair vs. Replacement
On average, it costs $2,800 to replace a pool heater. However, the heater type, pool size, and climate all impact the final price. Installation expenses are lower for electric and gas heaters versus heat pumps and solar panels, which can cost several thousand dollars. You may also need to factor in the pool heater’s predicted life span:
Gas heaters: 5 years
Electric heaters: 5–10 years
Solar heaters: 20–25 years
Consider replacing the heater when yearly maintenance and repairs reach 50% of the cost of installing a new unit.
Cost to Repair an Electric Heat Pump
Your electric heat pump will often display error codes to tell you what’s failing. You can also troubleshoot certain problems with your electric heat pump yourself. Here’s what to do first:
Ensure all valves are open and the water flow is sufficient
Make sure the filter is clean
Check electrical connections and see if the breaker got tripped
Look around the heat pump for blockages around the coil, such as dirt, leaves, and debris
For other issues, replacement parts may be necessary. Keep in mind that these prices are for parts alone—hiring a professional to install them will cost around $80 to $120 per hour.
Replacement Capacitor
If your heat pump won’t turn on, you may need to replace the capacitor for around $20 to $75. This could also be a tripped circuit breaker, so be sure to check this before purchasing a new capacitor.
Water Pressure Switch
A replacement water pressure switch could run you $20 to $50. This part is often to blame if you get a “low water flow” error code when you know the pump receives enough water.
Refrigerant Issues
Your pool’s heat pump refrigeration components are one thing that you shouldn’t attempt to DIY. If you encounter an error code suggesting refrigerant issues, call a local pool heater repair technician.
Cost to Repair a Natural Gas Pool Heater
If you’re having issues with your natural gas pool heater, start with some basic troubleshooting:
Ensure the unit’s power switch is on
Check that the thermostat is set to the proper temperature
Make sure the gas valves aren’t shut off
Clean out the skimmer baskets and pump pot if needed
If everything checks out, below are the costs to replace the most common faulty parts. Having a professional diagnose the problem and install the part will add an extra $80 to $120 per hour.
Flame Sensor
Replacing your gas pool heater’s flame sensor will cost an average of $20 to $200. If your pool heater turns on and shuts back off in a few seconds, this usually points to a bad flame sensor.
Gas Valve
Replacing a faulty gas valve could cost $175 to $600 or more. If your heater doesn’t shut off once it reaches the target temperature, it could mean there’s an issue with the gas valve. This can result in dangerously high water temperatures, so it’s important to address it ASAP.
Pilot Generator/Thermopile
Getting a new pilot generator costs $60 to $140 on average. When this part fails, the whole circuit (including the pilot light) will go dark.
Pressure Switch
A new pressure switch for your gas pool heater could cost around $40 to $60. If you know there’s proper water flow in the system, but the heater still isn’t working, this may point to an issue with the pressure switch.
Cost to Repair a Solar Pool Heater
One of the most important things you can do for your solar pool heater is to perform routine inspections. Debris and dirt tend to build up over time, which will inevitably cause problems with the heater. Aside from that, here’s what to look for if you’re experiencing issues:
Leaking panels or plumbing
Dirty or blocked solar collectors
Dirty filters
Worn seals or collector glazing
Unplugged wires or tripped breakers
Panel valves that aren’t fully opened
Be sure to clean your collectors out regularly with warm, soapy water. For other issues, you may need these parts.
Pump Replacement
A new pump for your solar heater could cost anywhere from $200 to $500. If you spot small bubbles in the pool when your solar heater isn’t working, there might be an issue with the pump.
Check Valve
A new check valve typically costs $20 to $30. You may need to replace the check valve if you can hear water going through the system when it’s shut off.
Solar Pool Heater Repair Kit
For most structural issues with solar panels, you can purchase a repair kit for around $50 to $60. These contain a variety of plugs that can repair leaking riser tubes for a variety of models.
Why You Should Hire a Pool Heater Repair Pro
If you hire a pool heater repair pro near you, you’ll spend between $80 and $120 per hour on labor and between $20 and $600 on materials. While labor rates may seem like a major investment, incorrectly repairing your pool heater can lead to extra costs and can also be dangerous.
Here’s why it’s ideal to hire a pool heater repair pro
Pool heater repairs can be complex, depending on the type of repair, so here’s why you should hire a pro:
Some issues require expert-level troubleshooting to identify and repair.
A pro can determine if you need to repair or replace the pool heater.
It can take several days to repair complex pool heater problems.
Pool heaters require electricity, which can be dangerous to work with if you’re not an experienced electrician.
Other pool heaters use gas connections, which should also be left in the hands of a skilled gas plumber.
Your pro can ensure a long-lasting repair that doesn’t void any warranties.
DIY mistakes can cause your pool heater to break beyond repair, leading to costly replacement parts.
If you want to DIY a pool heater repair
If you want to help with the repair process, focus on easier tasks, like:
Removing pool furniture and other obstructions
Clearing debris and overgrown landscaping from the work area
Checking the compatibility of any replacement parts
Replacing the cartridge filter
Cleaning the pump
Cost of Common Pool Heater Repair Add-Ons
The pool heater might not be the only issue with the pool. Other pool repair costs you might undertake at the same time could include repairing or replacing filters, adjusting water chemistry, or replacing pool tiles.
Pool inspection: $125–$250
Pool testing kits: $15–$20, plus the cost of chemicals to correct the water balance
Replacement filter: $150–$1,000
Drain pool: $180–$230
Drain repair: $400–$700
Refill pool: $55 per 5,000 gallons
Leak fix: $10–$3,500
Skimmer repair: $50–$300
Pool light replacement: $160–$730
Tile replacement: $20–$30 per tile
Some issues, like a clogged strainer basket, require little more than cleaning the basket with a hose, which costs you nothing except some time and energy.
Extra Repairs
Other pool repairs can include everything from detecting leaks and refilling the pool to beam repair and tile replacement. The price range is wide, so contacting a local pool repair service can be helpful if you’re unsure where the problem lies.
Pool Cleaning or Maintenance
One of the best ways to avoid costly repairs is to keep up with monthly pool cleaning and maintenance. The average pool costs $230 per year to maintain, with $110 to $350 being within the normal range. Costs rise during high-use months in the spring and summer and go down when not using the pool. You may also need to factor in occasional pool inspection costs to identify problems lurking where inexperienced eyes may not see them.
However, how often you get the pool cleaned and the level of service you get can increase the price of yearly maintenance. Larger pools with more expensive heaters can also increase the yearly maintenance price. Of course, if you take a DIY approach, you may only need a professional cleaning or maintenance visit once a year.
Next Steps: Finalize Your Project With a Pro
Be ready to explain the issues you’re having with your pool heater to help your pro troubleshoot the problem.
Let your pro know which type of pool heater you have so that they can give you an accurate quote.

Consider conducting a pool inspection, investing in a pool testing kit, and replacing other parts of your pool for a more comprehensive maintenance routine.
