Best small heater that is cheap to run?

Hi

Now the weather is getting colder we need to purchase a few heaters.

Last year we just got a couple of cheap fan heaters but they weren’t very good.

Can anyone recommend any?

Thank you

There is no such a thing as cheap to run heater...

Electric blanket is a lot cheaper to run if you are not moving around
Electric-based heaters are 100% efficient so will cost same to run per unit of obtained heat, it's just the method / speed of releasing / distributing the heat that changes. If fan heaters didn't float your boat then maybe consider convector heaters, ideally with integral fan.

Spare a thought for the OAPs with no heating.
Most fan heaters are only about 650W, which is probably why they weren't very good.

The amount of heat you'll get out of any heater is proportional to the wattage, and the wattage is proportional to the cost of running it, so there will be no such thing as a good heater that is cheap to run.
I use an oil filled radiator, as it keeps the heat for longer.
"a few heaters" will cost you a fortune to run.

Lets say you bought 3 of then and they were 1kw heaters. That's probably 13p an hour for 1, so 39p an hour for 3. Multiply that by how many hours a day and how many days over the next few months you'll have them on.

Yes that’s what we are thinking we only want to put it on for a few hours to warm up the rooms a bit.
Dull summary as it reaches the time of year when this site will see many similar threads:
Fan heater = instant heat and initially directional to the area requiring heat. No heat emitted immediately after being switched off so no wasted heat.
Convector heater = tends to initially emit heat upwards prior to some radiated heat so may take some time for the area requiring heat to feel some benefit; models with integral fan can speed distribution of the available heat. Holds some heat within its body and gradually releases it after being switched off but not a significant amount.
Panel heater = near-instant radiated heat to initially localised area. Holds some heat within its body and gradually releases it after being switched off but (typically) not a significant amount.
Oil-filled = takes some time to emit a noticeable heating effect, both upwards and via radiation; holds a significant amount of heat within its structure after being switched off so may be potentially wasteful if not turned off prior to end of heating requirement, although can be advantageous if the user prefers a gradual rather than abrupt lowering of warmth effect in a room (e.g. as the user falls asleep in a cozy bed).
(Storage heaters = generally not available as an aftermarket portable solution).
If each heater has the same power rating they will all consume and emit the same amount of heat; just the speed of releasing the heat and the distribution of the heat is different as outlined above.
The cost of running an electric heater is proportional to its power rating. For each 1000watts (kW) of heat rating the heater will consume maximum one unit of electricity per hour of active use (kWh). So any heater rated at say 2kW will consume maximum 2 units of electricity per hour. If you pay 15p per kWh unit them the maximum cost to run the heater per hour will be 2 x 15p.
All recently manufactured / sold portable electric heaters are legally required to have thermostats. If / when the set thermostat temperature is reached the thermostat will temporarily turn off the consumed power and during the "off" period the heater will consume zero or near-zero power.

An oil filled one you might be able to get away with unplugging it and leaving it off and wheeling it into a small room to heat that up without having to actually have it on.

I recall having one a few years back, they are quite heavy.
