Re: Heat pump vs Propane Heater
It depends on how you're going to use your pool. If you do not use your pool much when it gets cool out, or only use the heater to get your spa up to temp (98+ degrees), you'll want a gas heater that can get the temperature up high, when you want to use it.
However, if the pool gets used constantly, the heat pump will allow you to actually be able to afford heating your pool and maintaining your desired water temperature. For most people, this is in the low to mid 80's.
As the air temperature drops, it may take longer for either heater to get to your desired temperature, but again, the heat pump will be more cost effective to get it up to temps.
With 28,000 gallons, did your pool contractor recommend a solar blanket or a liquid blanket? Also, 100K BTUs in a Heat Pump is a little on the low side.
Last advice, depending on how cold it gets in Rancho Murieta, most heat pumps will shut off when the air temps get into the 50's. I suggest looking at Heat Pumps that offer a hot gas defrost or a heat and cold mode that allows them to run down into freezing temps.
If the heat pump is operated properly, they will be very affordable to run and maintain your pool heated to a temperature at (almost) all times.
Gas will get you there quickly. Heat pumps will get you there efficiently.
