We want to replace a standard tank water heater and our plumber recommended an indirect water heater. Does anyone have experience with what makes this a good/bad choice? We live in NJ, so our furnace is typically on during the winter months only.

Indirect tanks are great , another option is to use an electric tank and a plate heat exchanger and by using one side 120 volts of the tanks power through a 20 amp. 3 way switch to operate a cube relay the TT of boiler and the pumps can circulate water from bottom of electric tank to top of tank through heat exchanger, and boiler water through heat exchanger to heat the DHW . The elements switches are used to energize 120v coil of relay and thus control water tank temperature. The 3 way switch is used to direct power to cube relay for boiler DHW heating or using electric tank in normal mode of operation.
