Tankless + Geo/AC + Solar WH?
Anyone try combining water heating methods? We've had tankless (LP) for several years and just had geothermal heat pumps installed. We want to use the heat from cooling w/the geo pump when we can, at least to pre-heat the water before it goes to the tankless heater. We're also thinking about solar to do the same for the winter (and power the house). Can all three be effectively joined together? All hints/suggestions welcome.
