    Pool Heater Cost Question

    How much does it cost to run a pool heater? Any calculators out there?

    Want to know what it costs for me to heat up the pool say by 10 degrees...

    We have a 266,000 BTU heater.

    Cost for NG in Toronto is:

    16'x34' Inground Vinyl Pool. 65,500L. Hayward S244T2 24 Sand Filter. Hayward 1hp Super Pump. Raypak PR266 EN 266,000 btu,. AquaRite SWCG. Aqualamp LED 2 w/ remote

    Re: Pool Heater Cost Question

    I have no idea how our rates compare to yours - it costs me $100 per month to heat my pool in the winter. My guess is I am not heating it quite 10 degrees (we live in Houston) - maybe 7-8. I have a 30,000 gal pool. Hope that helps.

    Re: Pool Heater Cost Question

    Are you talking about a single time heating it up or maintaining the pool at 10 degrees higher than normal? The first is easy and there are several calculators to do that including one in my signature (Pump and Pool Spreadsheets). The second is a bit more difficult because it depends on how much heat is lost overnight and if you plan on using a pool cover. I have some approximations for this in the spreadsheets but they are only approximations.

    But for a single 10 degree rise, 80% efficiency, that would be about 1.44 M BTU and cost close to $8.

    Re: Pool Heater Cost Question

    Thanks for the help.

    The weather in Toronto is not favorable at all

    Highs of 65-70 and overnight lows of 55

    Every time we want to use the pool it's at 74 and we need to get it to about 84 to feel comfortable...

    Would covering it (with what?) help?

    Re: Pool Heater Cost Question

    Solar covers (bubble) can have up to a 15 degree gain so you might not need a heater at all but it depends on your weather. This is the type of cover I am talking about:

    Re: Pool Heater Cost Question

    Totally agree with mas985. If you want to retain the heat from your heater, you MUST HAVE a solar blanket. Get at least a 12 Mil, and it'll help heat your pool, and retain that heat on those cooler nights.

    Re: Pool Heater Cost Question

    Thanks!! 15 degree gain!? That would be awesome.

    When do you put the cover on? All the time when not using the pool or just at night?

    Also, how are they held in place? Our pool is irregular in shape.

    Re: Pool Heater Cost Question

    You buy an oversized cover and cut it out to the shape of your pool. It is best to unroll it and let it stay out in the sun for a couple of days before you cut it as it will expand some. Cut it out with bubble side down and it easily will cut with scissors.

    You want the cover on at night as this will keep the water from evaporating. Evaporation is what lowers the pool water temperature. If it is windy, having the cover on will help also.

    I have a free form shape and here is what I did for the cover and roller. Note the roller is attached to the cover.

    DIY Solar Roller

    With the cover I usually don't need any solar run time and currently, our average 24 hr air temperature is 73 degrees and the pool reaches 86-88 by the end of the day.

    Thanks. Is there a recommended brand for a cover?

    Re: Pool Heater Cost Question

    You can search this site, http://www.solarcovers.com/ and get some ideas. Most people report that the covers last about 2-3 seasons before the cover breaks down regardless of thickness.

    Re: Pool Heater Cost Question

    Our PB just gave us a cover today.

    Its 18x36 (our pool is 16x34). We have teh cover and a roller.

    He said that it just sits on the coping and is bigger for overlap...

    I though that it was supposed to be cut to fit and float on the water?

    Am I confused?

    Re: Pool Heater Cost Question

    Normally it is cut to fit because if goes over the coping, the wind can blow it around easier. Plus it looks nicer. Your PB is probably just being lazy.

    Re: Pool Heater Cost Question

    Looks like I'll have to do it my self.. We have the poles and roller as well.

    Are there any tutorials on where best to place the roller based on my pool pic above and how I should set it up? Should the blanket be hooked to the roller in the middle or at the end?

    Need help please...

    Re: Pool Heater Cost Question

    In April I had a 266k gas heater installed for my 17,500 gallon pool. Water was at 60. Raised it to 84 the first day and I keep the solar cover on most of the day and all night. I run the pump/heater about six hours a day. My first bill for 28 days was $176. At 90 cents per therm. Weather temps in Boise were similar to what you describe.
