dual coil indirect water heater
Looking for a dual coil indirect water heater. want to use a condensing gas boiler and a 50 gallon dual coil indirect water heater. Use the 50 gallons for domestic hot water needs and then use the top coil that would be piped into a duct coil that would be backing up a heat pump. what brand dual coil indirect water heaters are out there? Thanks for the info.

I like the Heat Flo line of tanks. They offer a dual coil as well as a dual coil with electric backup. The coil is smooth wall stainless so there is less accumulation of scale (no fins to load).
