Heat pump to hot water

stay_comfortable

Mitsubishi makes two sizes of heat pump to water converters 36,000 and 72,000 BTU. Both look very interesting. I have 3,000 square feet of existing in floor water feed radiate heat. Works great except for the propane bills! I am adding a 10KW solar system so a heat pump feeding the existing radiant heating system makes total sense. The 36,000 and 72,000 units are basically stacked plate heat exchangers that convert the heat in the compressed refrigerant to hot water that I can feed to my floor system. What I need is the mating outdoor compressor. Mitsubishi is not very helpful because they refer me to installers who have never heard about some of this stuff. What I have found so far seems like overkill municipal commercial building units that need three phase power. SO I seem to be looking in the wrong place. So what will pair up with a PWFY-P36NMU-E-AU and or a PWFY-P72NMU-E-AU?

Are you trying to determine the tonage condenser you need?
Their websight has a chart to build equipment, lets you plug in line lenghts and stuff to create a system before you purchase.
Play around with it, see if it helps.
