How Much Does it Cost to Run My Pool Heater?

How Much Does it Cost to Run a Pool Heater

Pool heating is a great addition to your pool, but figuring out heater operating costs leads to a headache. The process of calculating pool heater and heat pumps is simplified in Patrick’s article.

The formula essentially breaks down to fuel (whether propane, natural gas, or electricity) and runtime. Fuel costs vary depending on your region, so refer to your local gas or utility company for average prices. Runtime is controlled by the size of your pool and the size of the heater. If you undersize a heater, the need to run it to maintain temperature increases. This in turn increases gas usage and cost of running your pool pump. We always suggest oversizing your pool heater to get the quickest and most efficient pool heating.

Do I Need a High Elevation Heater?

High Elevation Pool Heaters

This article is for pools out West in states with “thin air” like Colorado, Arizona, California, etc. Pool heaters are like any combustion engine. They need air to breathe and maintain their flame, because without air they die.

A sizeable portion of heaters is self-adjusting (to a point.) The Pentair MasterTemp is able to adjust to elevations up to 9 000 feet without modifications. Hayward’s Universal Low NOx maintains its flame up to 10 000 feet. But for older heaters or the industry standard Raypak RP2100 Series, the lack of internal air blowers means thin air can lead to sooty, incomplete combustion.

  1. Matthew, while my heater is from Hayward, I realize many of the fault codes will assist in determining problems. It seems many of the problems I see can be traced back to electrical connections to the various sensors or circuit boards. Is there a method to protect these connections so they maintain proper operation?

  2. I have a Hayward H-150 pool heater. I am having problems with it coming back on after getting to the desired water temperature. If I jiggle the wires it will come back on – but not by itself. What do I look for? I had a guy look at it – but he didn’t know anymore about it than I do.

    1. I am a little confused. If the heater is at the desired water temp, it should shut off automatically. Also, if the problem is fixed by jiggling wires, I would try tightening the wires as they may be loose. If that doesn’t fix the issue, replace the temperature module/sensor.

      Try giving Hayward a call; maybe they can send a certified tech to take a look. 908-355-7995
