Ladia, my hubby just turned off the heat strips (they were on a separate breaker). We shall see.
MarkECIN, Some weeks ago I thought you might have a setting problem but as I read back through the thread I noticed on 1/17 you posted "This last week it's bee minuses and low one digit and even though we have the thermostat at 72; it shows 63 and we do believe the heat strips are kicking in a lot".
I think you need to get your contractor out and go over their calculations. Does the system perfom as per design intent and if not, why not. For example, the entering water temp had to be known in order to size the unit. Does it meet the design specifications, if not, why not? Ladia made some good points about the loop and they may be spot on, but I think you really need to have your contractor take ownership of this issue. They shoud know at approxamatly what outside air temp the heat strips kick in if they did an appropriate load calc. If the numbers don't match there is a reason.
