That's exactly the point I though I was making.

This also depends on the particular tariff of the electricity
supplier. Lots of utilities price their second and third... tier
winter residential electrical tariff very cheaply--resulting
in electricity being competitive with other fuels for heating--
simply so they can sell their baseload capacity.
When propane prices shot up a couple years, heating with
electricity was cheaper in many places.

So you think 60-65% would be a reasonable efficiency number for
estimations in wood stove planning?

After years of measurement and analysis I barely understand the energy
flow in my own house. I found leaks and improved the insulation until
the midwinter humidity rose to a tolerable level, and learned how to
manage the fire, but I still don't know how to plan for a different
house except to compare to a similar one.

I asked the question in the context of comparing different fuels for
estimating costs of space and water heating; it seems to me that heat
flow for any particular home would be about constant for any heater
regardless of the fuel. I've been planning for solar heating, but as
with anything AE, a back-up seems necessary and since reading some of
your posts, I've been taking a harder look at wood as a back-up.

Thus the 60-65% for estimations in wood stove planning question.
