A tankless water heater is a copper-tube boiler with a high pressure drop and no circulator. They are manufactured for domestic water heating; so using thdm for boiler service is a misuse according to the manufacturer. They are not less expensive than a boiler used for radiant floor heating.

The boiler is rated for these purposes and usually has a warrantee for 20 years. If you want a complete heating system, use a complete system designed by a radiant heating manufacturer. Weil McLain and other manufacturers will provide an entire factory-warranteed packeage installed by a qualified representative.
