Radiant off steam boiler

Steve GarsonSteve Garson Member Posts: 615
OK, I know this is not best practices, but...

The Combi-core water heater that heats my addition with radiant heat (15,000BTU heat loss) needs replacement. This will be my third and I want to do something that will last.  The heat load is rather small, so a dedicated boiler seems a bit expensive and unnecessary.  My WM-SGO-3 steam boiler has an Everhot heat exhanger tank to heat a small hydonic loop (10,000BTU heat loss.

I was thinking that it might be more cost effective to have another Everhot, or use the same one, to heat the radiant loop.  Any thoughts?
