Criteria for Choosing Oiled Filled Heaters

Performance

A robust and high-performance oil filled heater is able to quickly and efficiently heat up a room or space of a given size compared to a model lacking in power. It’s for this reason that you should consider both the output of the oil filled heater and the size of your room. It’s going to take more power and time to heat up the living room compared to the bedroom.

For use around an average-sized room, consider going with anything between 1500 and 2500 watts. Anything above this is obviously an overkill and unnecessary waste of money. Small rooms can do with an oil filled heater with at least 600W for there to be any significant changes in temperature during the biting cold of the winter.

Portability

Considering the performance limitations of a central heating system, you’ll have to frequently move the oil filled heater from one room to another to keep warm. This makes portability another equally important consideration. You don’t want something bulky and heavy that multiplies the chances of throwing your back out while lugging it from one sport to another.

To make the endeavour an easy and quick, consider going for a model with wheels and an ergonomically designed handle. Wheels also double up as a buffer and do a great job protecting their delicate floor surfaces and carpets from the heat.

Safety

You don’t want to be continually looking over your shoulder to ensure your oil filled heater isn’t catching fire. You want an oil filled heater with a choke full of safety features for that peace of mind and confidence to keep it running even when you’re fast asleep.

Additional Features

Under this falls the construction quality. You want to invest your hard-earned money in a machine that will provide you with several years of flawless, trouble-free service. The already mentioned wheels and handle substantially help with portability. Also, consider the aesthetics.

You want an oil filled heater that compliments the décor of your house while not attracting too much attention. Lastly, look out for a timer. It facilitates customizability by letting you choose the hours during which the unit will be running. You can set it so you always come home or wake up to a warm house.

Frequently Asked Questions

Q: When should I refill the oil in my heater?

A: These devices don’t require to be refilled with oil as it neither burns nor heats up as the machine runs.

Q: What is the ideal size?
