15 Best Oil-Filled Radiators for a Room

With energy bills at an all-time high, the question arises of heating a room with an oil-filled radiator or putting on the central heating.

Oil-filled radiators are economical and offer very good heat output if you need to keep a room in your house or apartment kept warm.

They are not heaters that will heat up your room instantly like fan heaters (which are more costly in terms of bills).

The oil inside them needs a little time to heat up. But once heated they are a marvel for heating up a lounge, office, bedroom, and even a shed.

Oil-filled heaters come in a variety of wattages and settings. Typically, they have 3 settings allowing you to use the lowest wattage at the minimum setting.

Having different settings matters when it comes to buying an oil-filled radiator, as it offers you flexibility in terms of control over costs and usage.

As of October 2022, the average prices for electricity are as follows (according to Ofgem):

• 34.04p per kWh for electricity
• 46.36p per day for electricity standing charge (£169.21 per year)

The key thing to remember is the higher the wattage you use, the higher the cost. So, to get the most out of oil-filled radiators use lower settings to start with.

For more control, an oil-filled radiator with a timer can make life easier for you to control when the heater comes on and goes off. For example, overnight or early morning.

Therefore, always take a close look at settings and timer options when choosing the heater for your room. Don’t buy something too powerful or underpowered for the size of room.

So, which type of oil-filled radiator offers the best kind of heat for your kind of room?
