With winter coming up, I have two options for home heating.
Central unit
- I can use the central unit and close/open vents throughout the house to heat up only the individual rooms I want. This would heat up rooms very quickly. However, to make this work, the living room with the thermostat will also need to be heated so that the thermostat reads the proper temperature. The living room is by far the largest space at about 2.5 times the size of the largest room.
Oil-filled radiator
- I can use an oil-filled radiator to heat up an individual room. This would be much slower, but I wouldn’t have to heat up the entire living room. However, the oil-filled heater might not be as efficient as the central unit. I don’t know. I plan to rarely heat up the living, no more than once per month.
Edit: The central heating unit is actually a heating kit made up of a few coils that is added to the central a/c.
Edit 2: Where I live, it might freeze once per year over night for a few hours.
Which would be more efficient on the electrical bill, and would t be considerable or negligible?
The problem is that you increase the humidity in the room with every breath. That humidity is going to condense onto the cold walls of your living room and consequently be a breeding ground for mold.
That’s a good point I wasn’t aware of, so thanks for bringing it to my attention. Another user recommended that I set the heater to run at a low temperature in case it gets too cold, but also to run the fan regularly so that the air moves about and addresses the humidity issue.
