Is it cheaper to use a plug-in oil radiator to heat an individual room, or run the central heater to heat an individual room and living room?
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.
i recommend you avoid polluting the air in an enclosed space. So no oil burning inside the room. The central heating would be a much better option in my opinion
Alternatively, weak (1 to 5 kwh) electric heaters with good placement can heat rather large rooms without wasting nearly as much power
I think by "plugin" op means electric rafiator filled with some special oil that dissipates heat. So it's still electric just the heating element will heat and circulate oil.
It adds some efficiency because once you have a radiator full of hot oil in the radiator it tends to release the heat for a long while after the electric is shut-off.
Most electric space heaters send a plume of hot air arcing upwards.
You end up with a nice heat storage device to radiate warmth at the level you want to use it for longer than a normal resistive space heater using the same energy.
I agree that burning oil would be a terrible idea. In this case, the oil would be in an enclosed radiator that is designed to function as an indoor heater. Thanks for looking out tho!
That is actually pretty cool! In that case, the slowness shouldn't be a big issue. As soon as you've got a comfortable temperature you only need to maintain it
