Can water heater elements be used in a radiant heating application?

I have a project that requires some radiant heating but was wondering if water heaters function properly if they are not immersed in water.

The system COULD be designed to work, but it’s going to be incredibly inefficient. The coil will need a TON of air flow to carry away enough heat to prevent overheating.

Alternative solution: Buy replacement heat elements for space heaters. They’re designed for air transfer. Just be sure that you size your air handling system (fan) properly to prevent over heating. Also, do not forget to wire in thermal relays to cut power to the coils if it should over heat. Size the element cluster and air handler appropriately for your heating demands so you A) meet your needs and also B) don’t have excessive power cycling. If the system runs almost full time, it will be better in the long run than switching on and off every 5 sec.

Be sure that your thermal relays only cut power to the coil, not to the fan. You’ll want the air flowing still to help cool the coils down and to maintain air circulation through your entire system.
