Thanks. We're in Vermont with an unobstructed true southern exposure. Looking at a PV pumped system.

I'm looking at SHW. I've got an existing 3 year old oil-fired boiler that provides radiant heat and domestic hot water. The domestic hot water is stored in a 40gal tank. (We use very little water each day - typically 50-100gal/day total - hot & cold for the 3 of us).

What I'm wondering about is the configuration of a SHW system. I'd like to have our cold water line run into the SHW tank, then have the outflowing hot water go into the existing 40 gal tank, then out to the supply lines to faucets, etc. I am not interested in electric backup on the SHW tank. In this reasonable? Thanks.
