Hot water and radiant floor heat source?
I’m getting ready to replace my 75 gal combo hot water heater/ radiant floor heat source. Should I go with the same type of unit or a tankless combi heater? I have a power vent in my current unit. I need to supply hot water to the whole house and radiant heat to a 1000 sq ft lower level. (2 separate water heaters do not meet code.) Thanks for any recommendations.
