Advertisement Okay it's gotten slightly colder here and my room has already dropped to 17c at night... Bought a cheap electric space heater last year but turned out to be so expensive to run. Any recommendations for one that's cheap to run and has an accurate thermostat setting? Looking to spend up to £100, maybe a bit more if necessary. Room is a small bedroom and just want to take the edge off at night, keeping it no lower than 18c. Cheers!
