Jeff,
My system operates most of the time at 110F and ramps up to a max water temp of 130F on the coldest days. I don't know what the hot side temperature is for the mini split I'm considering but I do know that I have a GE heat pump hot water tank that can be set to 140 so I guess I've been assuming that the mini split will deliver a high enough temperature to fill most of my needs and then, if necessary, the primary electric boiler will pick up the rest. (see attached)
It would be nice to know what the output temperature is from the compressor. Then I could better size the HX but I have not found that data yet. I am actually concerned that it may be too hot for my normal operation and that I might have to temper the output.
