Thanks for doing the math. 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. :/

This study
http://www.focusonenergy.com/files/D...udy_report.pdf
seems to say that, for 9 yr old houses in Wisconsin,
"the overall stock of Wisconsin single-family homes,
. . .has an average heating intensity of 4.4 BTU/ft2-HDD"
If you assume 75% efficiency for gas and oil burning appliances your house comes in at closer to 0.75(11) =~ 8.

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.

Then its a very inefficient heater.

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.
