I presume that "d" stands for "Failed Miserably in Energy Conservation." We are meeting with an energy assessor on Thursday. Will see what he has to say. :/ Last edited by akimbo; 05-26-2009 at 07:33 PM.

Thanks for the reference. I glanced through it and I see that I'm going to have to wrap my head around the heating intensity units. Currently I don't get it. I spoke to the Econo Heat people again today and they said that their 400 Wall unit yields 1000 BTU. Last edited by akimbo; 05-27-2009 at 02:00 AM.

Since a regular baseboard heater using 400watts, would give you 1,365 BTUs. 1000/1365=.732 So its only 73.2% efficient.

It's also not possible. If 400w goes in then 1365 BTU/hr must come out as something; heat, light, radio waves, noise, mechanical motion, something.
