Your post might indicate a miscpnception. A radiant heating system
requires a boiler, not a water heater. Call a heating supply and get a
price on a new boiler and a new furnace. Last time I checked furnaces
were half the cost.



Depends on what he's thinking.

Some of the applinances we think of as boilers are actually water heaters.
Boilers have to be ASME rated, WH's don't in most cases.

Besides, IMO, water based heat is more comfortable.
