Rainwater tank ground-source heat-pump synergy
I’d like to look into the feasibility of using a open-loop ground source direct-exchange heat pump system in conjunction with a below grade rainwater catchment storage tank.
My company installs onsite water conservation measures. We are designing a rainwater to irrigation system for a school but they are interested in retrofitting existing structures with a ground-source heat pumps. Heating and cooling load are about evenly split in this region (climate zone 8-9).
Have you seen this done before? Any considerations as we look at this design?
