By moving the warmer air from upstairs back down. There are systems available that can be installed to do this for you, or you can make your own.
If the wood stove is in the basement it will heat up the rest of the house but if it is not in the basement you have to find some way to vent it down there.
Because heat rises and obviously upstairs is higher than downstairs so the heat will rise to upstairs.
Usually not.
A basement of a house is the room or space that is below ground level. A basement appliance that can heat your house is a furnace.
Heat rises.
Do you have problems with frozen pipes? Does someone live in the basement? You won't lose much heat through the basement because heat rises.
If the basement has ventilation to outside, the answer is yes. Heat loss from the pipes will escape outside the house. If the basement is closed to the outside then no, the pipes need not be insulated. Any heat lost from the pipes will provide some heating to the basement that will rise into the house.
No. Products of combustion are: carbon dioxide, water, carbon monoxide, and light Carbon monoxide this is why it is vented outside. CO is odorless and can KILL YOU.
I own an Eden Pure heater. My youngest daughter sleeps in my basement. The heating system we had downstairs was horrible so we bought one of these heaters. It kicks out so much heat that we have not turned on the heat upstairs. I have not seen a difference in my electric bill but I am very happy with the way it works.
Turn off the heat to the basement, first and second floors?
if you want to, go ahead, no reason not to
The basement is underground so the sun's heat does not reach it, but probably its just that above ground is warmer rather than below ground is cooler.
