upstairs heating in N. E. Gambriel?

Question

I want a heating source for my otherwise unheated upstairs.
I have an oil air furnace for the downstairs. Do not want ducts running thru the inside walls to the upstairs....have propane for hot water....any thoughts on Renai or Monitor heaters...propane vs. ? other sources... I have a chimney that runs upstairs also, but has the furnace and woodstove running off it downstairs. The most economical source is wanted.
Also, it will be only heating at 60 degrees. The lowest it gets in the stark winter is 38, pretty chilly sleeping !

Answer 1

You can get a substitute for the chimney which is a through-the- wall vent. It brings in combustion air and sends out smoke through concentric pipes.

As far as fuel you would need an oil tank on the ground floor so that it could be filled and I doubt that the suction on the oil pump could raise oil to the upstairs so oil heat will not work. That gives you propane as the best choice (electric heat is very expensive to run).
