Our advice to not run heaters overnight or unattended is the safest policy to adopt. The safest heater is one that is unplugged (just don't step on the plug). However, we understand that if your feeling cold and vulnerable you may be tempted to ignore this advice.
If your bedroom is notorious for getting cold at night, we have bad news as using a halogen heater while you're asleep is strongly advised against. Daniel Dwyer at Village Heating dubs them as unsuitable for cold nights as 'they must be switched off while sleeping.
The safest heater to leave unattended is generally considered to be an oil-filled radiator heater (1). These heaters are designed to retain heat for a longer period of time, reducing the risk of overheating or starting a fire.
As for safety, They are rated as the SAFEST form of portable Heating appliance. They have an overtemperature fusable link, knockover switches, and thermostatic controls. When they fail, they fail Safe.
Halogen heaters tend to be the cheapest radiant heaters as they have a low power rating (but also produce less heat), while oil-filled radiators are often the cheapest convector heater because there is a thermostat to control the temperature.
Costly to run – halogen heaters are usually quite costly to run compared to other forms of heating depending on the type of halogen heater, particularly during the winter months when the heaters have to left switched on for longer periods of time.
Halogen heaters don't release any carbon dioxide or any other harmful gases.
Dr Deborah Lee, of Dr Fox Online Pharmacy, agrees. “Halogen lamps are safer than other types of lamps because they do not produce carbon monoxide like many other heaters, so are safe to use in an indoor space.” They produce instant heat and are best for heating a small space.
Oil heaters
They're often fitted with an automatic shutoff feature which means they'll turn off automatically if you leave the heater unattended. This makes an oil-filled heater relatively safe to leave on at night.
But it also comes with certain risks. For example, halogenic and incandescent bulbs can cause fire if left on for 24 hours or more. Ultimately, this makes them potential fire hazards and is not the best way to keep burglars at bay.
Choose the heater based on your room size
The size of your room is a crucial factor when selecting a room heater. For smaller spaces like cubicles, consider regular halogen heaters. Fan-based room heaters are ideal for slightly larger areas.
That being said, ceramic space heaters are safe to leave on all night because the outside shell does not heat up and thus remains cool, posing no harm to you or your family. Ceramic heaters are among the safest heaters to use throughout the night.
This shows natural gas is the cheapest type of heating to run and heating oil is the most expensive way to heat a home.
Candles are, of course, a burning flame and like all flames they produce heat. So yes, candles do heat up a room.... but only very, very slightly! To get any sort of meaningful heat from candles, so many would be needed that they would become a fire hazard - so no, we do not suggest that you try it!

While halogen heaters are a great option for providing warmth in super-quick time, there are a few downsides to consider: Safety – Halogen heaters become extremely hot to the touch, so can prove dangerous around children and animals. They can also be a fire hazard, if objects are in close proximity to the heater.
As halogen heaters have intense directional power, where they're placed is especially important. Put them too close to a flammable item, or a person, and there's a big risk of incident or injury. Make sure you keep these heaters well away from any potential hazards, whether that be furniture or people.
These heaters not only have the apparent negative effects, such drying out your skin, but they also deplete the air's oxygen supply. Since halogen bulbs are smoke-free and environmentally beneficial, the heaters don't emit any carbon monoxide.
Often you can run them at 400, 800 or 1200 watts, so that would work out at: 400W = 12 pence per hour. 800W = 24 pence per hour. 1,200W = 36 pence per hour.
They operate by using halogen bulbs that emit infrared radiation when powered on. This radiation directly heats objects and people in the room, offering fast, targeted warmth.
