currently I have a Hayward propane fired heater for a pool with a spa where the spa waterfalls over into the pool in normal heat and/or filtering. There is no waterfall when only in spa mode. I have a Jandy Aqualinks control and salt water chlorinator.
I saw Raypak makes a heat pump for low humidity applications (6300 Ti LH). It has two coils and decides to run on one or two coils dependant on the outside temperature/humidity conditions.
I would like to stay with Jandy since I have mostly Jandy equipment now.
The things I am trying to figure out now are:
1.) Since the Jandy has a higher BTU (137 vs 115) and Jandy states they already have a large "specially finned" coil, will the Jandy perform as well as the low humidity Raypak in cooler low humidity locations? I don't care if one costs a bit more to operate than the other as I am trying to ge the most heat output given the environmental challenge.
2.) since we will use the spa a few times where the outside temperature is 45-55 degrees on winter nights, should I also get a heat option to be sure the coils don't freeze and the unit continues to operate at the lower temperature? In these cool winter temperatures the humidity is usually about 45%, in the warm months where we may need to kick up the pool heat a bit and heat the spa, the humidity averages 20%.
The installation will be in La Quinta California near Palm Springs (desert environment)
At any rate I am certain the cost of propane being near $4 a gallon and electricity at .114 KWH I will save a bundle switching over to a heat pump.
Any insight on my two questions above will certainly help me and others in desert areas as me
