Affordable Air-to-Water Heat Pump for climate zone 6B, Colorado
I’m looking for an air-to-water heat pump that I could use with a low temperature hydronic distribution system for space heating. I would also like to use the heat pump as the preheat for domestic hot water.
The mini-split air-to-air heat pumps are pretty ideal in many climate zones in the USA. On the western slope of the Rockies in Colorado, air conditioning isn’t usually necessary. So I’d prefer one heat pump to provide space heating and much of DHW.
I’ve seen that some manufacturers provide air-to-water heat pumps for European markets. There are also some rather expensive units available in the USA. Any news on affordable units coming to the USA market?
For the cost of some of the more expensive units currently available, I may be better off going with a larger PV array and an electric boiler. I could use surplus summer production to offset heavier winter electric consumption. (My utility only pays avoided cost for any annual net meter surplus.)
Solar thermal is pretty effective out here, and there are some rebates available, but the heat pump option seems like the lower maintenance route.
