Common Problems with Heat pumps

Swimming pool electric heat pumps are an awesome way to save energy.  We sell Pentiar, Raypack, and Aquacal heat pumps.  We also perform service including capacitor replacement.

Heaters are larger gas appliances than the furnace in your home.  They require an enormous amount of gas supply to keep them running properly.  This starts with the gas meter. Many homes have meters that are not large enough to provide sufficient flow of gas to the heater. This causes the heater to form soot and this causes the heater to run inneficiently and cause significant problems with operations.


The second problem is nature.  Heaters outdoors are an invitation to mice, birds, and other animals that enjoy making nests.  As a result, inducer motors, and sensors may not work due to these nests.  Mice also like to use the restroom inside of heaters causing parts to rust and they enjoy the taste of electrical wires.

Missing or improper sediment traps

Natural gas is dirty. A sediment trap does exactly what is sounds like and captures this dirt keeping it away from the gas valve.  Natural gas should feed into a heater from the top down and then tee into the heater with the sediment trap at the lowest point.  Many installers install them in a horizontal plane and this renders them useless. Here are two examples of improper sediment trap installs.
