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?

      Another good way to do it is to actually hire a HVAC individual on and have them come out and just look at the system. But be wary of that. Some of them are not exactly the most brightest bulbs in the world. And they will tell you, oh you have to have them all open at the same time you can’t close them. Without actually looking at the system. I’ve run into that to myself. In my house, I can close, almost half of my vents without any issue, and yet a number of techs have told me I can’t do that. Until I make them go and look at the furnace and count the number of vents and look at the size the vents then they go oh yeah, I guess you can.

      Like I said some of them are not very bright. So maybe it might pay to hire on a couple of them to really look it over. Make sure they really look at the central system, blower furnace, etc. and then also look at the vents in the size of the vents.

      Yes, it cost some money upfront for them to come out and help you with it, but you can get an idea of to what they’re doing.

      The other option is to go down to the library and check out a bunch of books on the subject and try to learn it yourself.
