I have an indirect hot water tank that is linked to an electric hot water tank. The indirect tank gets heat from my Noritz propane boiler that heats a zoned water radiators. The price of propane is now very expensive.

I am considering an air to water heat pump that I would link into the indirect tank and the heat exchanger would pick up heat for the circulation system for the radiators. I also have a large wood burning space heating stove on the first level. I can capture heated air and blow it down to the basement to improve the COP of the AWHP. The heat pump would eliminate the need to dehumidify the basement.

In summary I would use the AWHP in the summer and shoulder season when the propane boiler is not in use. There is company in Maine nyle.com that sells the AWHP at a reasonable price.

Has anyone designed a similar system?

Thanks
