If you're beginning the search for pool heater repair near you, you should be sure to consider a few key factors during the process. One of these may even involve purchasing a new heater and finding pool heater installation services nearby. Selecting the ideal heater is a tricky decision. Rather than choosing the pool heater that sounds best right away, consider some of the advice below to help you with pricing and product selection.

Heating your pool is a convenient way to keep it available to you and your family to enjoy through the seasons a bit longer. Swimming pool heaters are the most complicated piece of pool equipment in your pool system. They are complex devices consisting of several moving parts using either gas or electricity to supply heat.

To ensure your pool heater is ready to use, you should treat it the same as you would a home heating system: with regular maintenance and checkups. Below are some factors that could affect the cost of repairing your pool heater.

Why is My Pool Heater Not Working?

A myriad of factors could keep your pool heater from functioning properly. It's a good idea to try to determine what problem you may be up against on your own, but you should always get in touch with a pro to ensure that you take the best steps for your system.

Lack of Maintenance

If you haven't taken care of your heater with regular maintenance and upkeep, it could be more expensive to fix. Most people realize that their heater is broken when it stops working or their energy bill suddenly increases. By this time, a simple repair may have become a complicated one. This costs you more money.

Watch for these common issues with your pool heater:

  • More expensive bills due to decreased system efficiency
  • Problems with controls or system power, which could point to inadequate connections
  • Excessive noise due to equipment that has broken or fallen into disrepair

The general rule of thumb is to seek annual pool heater maintenance. This helps you find issues as early as possible. Annual pool heater maintenance service will run you between $100 and $200.

Your Heater May Be the Wrong Size

Not only will the type of your heater dictate the price of repair, so will the size of your heater. Larger heaters will require more work, and it may be more difficult to get to the problem.

Your Heater is Not Protected from the Corrosive Saltwater in Your Pool

Saltwater is highly corrosive, and a heater must be equipped with a special heat exchanger and other features to handle it.

The heat exchanger allows a pool to be heated via hot water from an outside source. When hot water is brought in via a boiler or solar-heated water circuit, it's easy to avoid saltwater corrosion.

Because these heaters are so specialized, they are more expensive to fix.

Environmental and Other Issues

The problem could be electrical, a matter of broken parts, or an animal that has taken up residence in the unit. There are also other factors to consider such as leaks, soot, rust and control failure.

Check the Warranty

Your pool heater's warranty determines how, when, and why you can call a pro for maintenance. Solar heaters' warranty costs usually cover a sizable chunk of repair expenses. Electric heaters require more frequent service than their solar counterparts. Their warranties may range from one to ten years depending on labor. 

Gas heaters' warranties are often the shortest and most restrictive. Maintenance should be frequent and the cost of repairs must be considered. Warranties generally last a maximum of five years and only include parts.

Some of today's most popular pool heaters offer a good springboard for further research:

How fast does a pool heater heat a pool?

The answer to this question depends on your unique heater and pool. Nobody likes to play the waiting game while they hang around hoping for a dip. A rough estimate for adequately-sized heaters can be determined through this formula:

(# of gallons of water in pool) X (8.34) = ____ lbs. of water

Once you've determined pounds of water present, divide that number by the heater's BTU size. The resulting number is how many hours it will take to raise the water temperature by one degree.
