There are several different ways to heat a home. My house has a forced air furnace and the warm air blows out of vents in each room. The furnace uses natural gas to warn the air. I have a thermostat on the wall to set what temperature I would like to maintain in the house, and the furnace turns off when it reaches that temperature.

I can imagine what you're describing because sometimes I see all of that in movies.

Since we don't need heaters in our country, it is an interesting piece of information for me to know. Thank you for your explanation.🤗
