How to Insulate an Oil-Fired Boiler

Many people know that it’s economical to insulate their hot water cylinder. If your hot water tank doesn't have an insulation jacket, it will cost you more to keep your water warm. The same is true, to a slightly lesser degree, of oil-fired boilers. If you have an oil-fired boiler in a particularly cold part of your house or outside, it's going to use more energy to fire up than if it were warm. Insulating your boiler will make it more efficient and save you money.
