Springtime is here, and with it comes the anticipation of the upcoming summer swimming season. Along with all of the excitement of getting in the pool, it also means routine checks to ensure that your pool is functioning properly.

One of the important maintenance tasks is to check your swimming pool heater to be sure it is functioning properly and efficiently. When you have a heater that is powered by natural gas, liquid propane, or oil, there’s always a threat of combustion. Our certified technicians know how to safely work with the complexities of pool equipment, and safety is our top priority.Swimming Pool

Here are a few common issues with your swimming pool heater, and why we recommend a service call.

The heater is leaking water: The pool heat heat exchanger may be leaking because of chemical or sanitizer damage. The damage may be from winter freeze – usually leaking upon spring start-up, and usually on the return manifold. There could be a gasket leaking, or a loose connection to the pressure switch. Finally, a drain plug could be loose, or missing an o-ring.

The heater pilot doesn’t light: This could be due to low gas pressure, inadequate air supply, or improper venting. Make sure gas is turned on; with propane, make sure the tank has fuel. Also check for water run-off from roof or sprinklers that may be flooding the heater. Check to make sure the heater pilot tubing is intact and not clogged.

Heater won’t reach the desired temperature: The thermostat may be set too low. If the heat loss is greater than the heater input, the heater may be too small, outside air temperature is too low, or your heater may have an inadequate gas supply. You may want to install a solar pool cover to slow heat loss from your pool. All pool heaters have high limit switches to prevent overheating. A faulty high limit switch could shut off the heater, or the problem could be that the heater is truly overheating, perhaps from improper exhaust out of the top of the heater.

The heater makes a whistling noise: Low gas pressure can cause whistling in the burners. It can also be attributed to partially clogged burner orifices.

These are just a few of the reasons your swimming pool heater isn’t working properly. That is why we recommend having one of our service technicians inspect your oil or gas pool heater.
