Brief Beginner’s Guide to Choosing a Home Radiator

The oil-filled radiator can be turned off before bed, and since the oil is hot, it will continue to produce heat. One of the downsides of radiators is the absence of a fan, but if you don’t like noisy space heaters, then this might not be a major problem for you.

When shopping for the best home radiator, DeLonghi makes some of the best products available, and units from this brand are made with thermal tunnels, which allows them to efficiently heat a space.

Fun Fact: Some radiator heaters aren’t filled with oil, and instead, they use flat sheets of mineral mica, which produce heat.

What Are They?

Home radiators are space heaters – but instead of using your HVAC system to heat the whole house you can just use them to heat a single room. They look like a traditional house radiator, but are much shorter in length, and are generally oil filled and portable.

They are made of metal columns, and inside the columns are cavities which contain the oil. There is a heating element at the bottom of the heater, which heats up the oil. The oil stays hot and transfers the heat to the outside of the radiator and then the room by a combination of convection, conduction and radiation.

Oil filled radiators are more expensive to run than gas heaters, but can be used in homes where gas radiators can’t. This is because gas radiators need to have ventilation as they produce too many fumes and reduce the amount of oxygen available.

Fan heaters are another possibility for heating but they are more expensive to run than oil filled radiators. Halogen heaters are cheaper to run, but they don’t output as much heat – so oil filled radiators have a happy medium of being good at heating but not too costly to run.

Who Can Benefit?

The great thing about oil filled radiators is that they keep the room nice and warm as a whole, for an extended period of time. That’s because they work by heating the space around them which then circulates evenly around the room. So if you are looking for a way to heat a room and want to feel nice and warm and comfortable then they are a great choice. They are also silent, so won’t annoy you with their noise like fan heaters do.

If you would just like to heat a room for a  few hours maybe before you even get there then home radiators often will have timers so you can program them. You could program them to turn on half an hour before you get up in the morning so that your bedroom is nice and cosy when you wake up.

They also have thermostats which means they won’t be running at maximum heat all the time, so can be very cost effective as you can set the temperature to what you need.

Do you ever heat your whole house when you are actually only in one room? If you do, then buying one of these radiators will save you money as you can just heat the room you’re in. They have wheels so you can even roll it around to a different room if you need to.

What To Look For?

The best home radiators have thermostats so that you can change the temperature to what you need. Some also have programmable timers, so if you’re planning to get the house warm before you come home from work, or would like it warm when you get up in the morning, then you might want to look for one of these.

Also look for a thermal cut off so that the unit will turn itself off if it gets too hot. This is a good safety feature to have. Another safety feature is rounded edges, which can be more important than you think since it is made of metal and could really hurt someone who runs into it if it’s not rounded.

Look at how many watts the heater gives out – this will give an indication of how powerful the heater is. A higher wattage would be more suitable for a larger room, or for if you are wanting your room to get warm more quickly.

On the other hand you don’t want too high of a wattage, or it may consume a lot of electricity and be expensive to run. 1500W is a good standard wattage to look for.

If you are going to be away from home for a while or are worried about something in your house getting too cold, you can find some radiators that have anti-freeze features. Basically once the temperature gets too low, it will automatically turn on and warm up the room for you.

What To Avoid?

Don’t buy a radiator that is too cheaply made or has been knocked around, as some cheaper models may end up leaking oil. Also avoid getting one that doesn’t have a handle, as they can be quite heavy and difficult to move without somewhere to grip.


Do I have to refill the oil?

No you don’t have to refill the oil because it stays in the radiator and just keeps circulating through it.

Are home radiators safe to use?

Home radiators are much safer than some ways of heating, since they don’t emit fumes… however like all heat sources there are still dangers. With these type of heaters the biggest danger is getting burnt or starting a fire. The best way to avoid getting burnt is to watch how hot you let the heater get with its thermostat, and keep small children away from it if it is very hot.

To avoid a fire it is best to keep all objects at least three feet away from the heater. They do usually have a cut off system to turn them off when they get too hot, but more cautious people might prefer not to leave them on for too long of a time. They can also be a fire hazard if they are turned on their side so they need to be kept upright.

Can they be used in any room in the house?

They can pretty much be used anywhere, apart from some manufacturers give warnings not to use them in damp rooms such as laundry rooms or bathrooms – as the damp might damage parts of the radiator.

Do they smell?

These radiators shouldn’t smell under normal usage – but when they’re first used they might. Most manufacturers recommend that when you first get them you turn them on for a couple of hours in a place that is well ventilated to get rid of any unwanted fumes.

Wrapping Up

The best radiator heater can heat a space in your home, and it doesn’t cost a lot of money to run. These products produce heat by heating up oil, and when you turn the power off, they’ll continue to produce heat for a period of time.

The only downside is that they can take longer to produce heat than some alternative space heaters. However, if you’re looking for an affordable, convenient and safe way to heat a space in your home, a high-quality radiator heater can help.
