Use an Oil Filled Radiator for heating a large room
One of the best things I have bought this year. The Prem-I-Air 2.5kW Oil Filled Radiator heats up the garden office a treat. Gets the place so warm we have it on timer as it can be overbearing, and that’s on the low setting. Makes no noise when it is on which is a major bonus. The timers are even easy to use so you save a bit more money.
