Hydronic Heat Pump Piping with Boiler
I saw the new Climate Master Tranquility THW water to water heat pump at the Iowa Heat Pump's annual conference. It's an interesting machine that they claim will produce 145 degree LWT. It's only available right now in a 32,600 btu size. It also does not produce chilled water.
It has some other neat features but without chilled water it won't work for me.
