The Different Powers Of Oil Filled Radiators And What Size Rooms They Can Heat

The performance of an oil filled radiator is affected by two things and these include its size, power rating and the size of the room. For this reason, you need to put these factors into careful consideration so as to obtain the best radiator that will give you the value for your money.

It is worth noting that the size of the radiator is not necessarily directly proportional to the size of the room but its power rating is. This implies that the larger your room, the higher the power rating you are going to need to get the job done.

The Calculations

Oil-filled radiators are all about calculations of the wattage and the size of the room. The size of the room has got to match the wattage. Here’s the bottom-line, a standard room is expected to have a ceiling height of about 2.8 meters. For every square meter of the room, 100 watts are consumed. This means that a 10m2 room can be heated perfectly with a 1kW oil-filled radiator.

However, there is a difference in the heating requirements between a living room and a bedroom. A 10 square-foot bedroom can be heated perfectly with a 750 watts heater. In this regard, apart from determining the area of the room you want to heat, it is also important to distinguish between the living room and the bedroom. Also, the shape of the room should also be a pretty important consideration to make. For example, if the room is large and rectangular, it is going to be pretty hard to use one heater. For a square shaped room, though, a single oil filled radiator with the correct wattage will do the work perfectly.

Room Size of an 800W oil filled radiator

Let us see what room size an 800w oil filled radiator can heat. First, supposing the room is a living room, our calculations will are based on 1kw per 10 square feet. If 1kW can heat 10 square feet of a room, then a heater rated at 800w will only heat a up to 8 square meters of a living room. If the room was a bedroom, then the 800w oil filled radiator will be capable of heating up to 10.67m2 of the bedroom.

Room size of a 2500W oil filled radiator

Well, 2500W is a pretty powerful radiator and going by the calculations above, this will be able to heat a room of up to 25 m2 if it is a living room and 33.33 m2 for a bedroom. Most of the oil filled radiators in the market have this rating or something close to this. So, it is likely that you are going to get one with such ratings. If your living room is, say, twice as big as 25 m2, then you will need two of the 2500W oil filled radiators. If you are buying it for your bedroom, make sure the room is approximately 33 m2 to get the desired heating results. Observing these ratings will help in boosting your experience and hence your satisfaction levels as a customer. This is because you will get the optimum performance out of your oil filled radiator.

In conclusion, the choice of the right oil filled radiator is really dependent on the size of your room and if you fail to put this factor into consideration, there are high chances that you will not get the best value of your money. As such, ensure that you buy the heater whose ratings correspond with the heating needs of your room.
