Hi John;
In a quick calculation (done twice with the same results)
I come up with only about 5000BTU/hr. (4900 including
perimeter and infiltration losses for a two car garage, but
not any windows. So, a little plug in heater might maintain
the temperature but would not be able to warm up a cold
room in an acceptable length of time during the heart of
Winter. And, being able to allow the room to set cooler
most of the time is likely to be an effective energy saving
strategy, especially when coupled with something like a
simple low-cost Solar air heater on the South wall.

That very well may be true. Expanding the living space even
without electric heat may be pushing the capacity of the house's
existing electric service to a point where it should be increased.
A small mini-split heat pump such as the 9000BTU Fujitsu
could supply both heating and cooling at a very high efficiency.

Hello (name?)
I will suggest the TimberWolf 2100 which you can buy
online delivered in the $600 range (stand may be extra). It
is very efficient at about 86%. Get it before the end of the
year so that you will qualify for the 10% federal tax credit.
