thing to remember is these heaters come in various sizes.. typically the water heaters can be bought up to about 45-50k BTU, which can heat a ton of space esp if you are insulated..
a 5KW air heater is typically about 17000-19000 BTU.. remember this is INPUT BTU. the efficiency determines the actual amount of heat going into the conditioned-space.
I know my 16kw water heater sends a lot of its heat outside but some of that could easily be recovered with a secondary heat exchanger. I ay endeavor into that next year... although ive found the thing heats my bus amazingly well so I may not break what isnt broken!
