I've ordered a top-up of heating oil (Kerosene) which should be here in good time. Unfortunately many rural properties don't have mains gas, so we rely on oil or LPG. The oil boiler has a high pressure pump that blows a fine spray of oil and air into a combustion chamber and this heats water that supplies the radiators. The boiler therefore uses both oil and a small amount of electricity. Gas boilers usually have fan assisted combustion and circulating pumps which also use a small amount of electricity.
We've also splashed out and ordered a new lounge suite - two sofas and an armchair. We changed our minds on the one we had seen earlier and chose a slightly more compact one. We won't get it until late April because they are built, or at least upholstered, to order.
