Don't waste money on a new boiler
If you already have a condensing gas boiler, the chances are you don't need to change it. Boilers should last 20 years. Your biggest household saving this winter is keeping your boiler and making it more efficient.
Is it cheaper to heat one room?
It's a really common question. We compare the cost of heating a single room with an electric heater verses heating the home with a gas or oil boiler. We also explore the costs of running a wood burner and using an electric blanket
HOW DOES IT WORK?
Most boilers are left at their factory settings which are set to maximum and not efficient
This means boilers are only C-E rated in the home, equivalent to just 75-85% efficiency
With a little bit of know-how, you can increase your boiler's efficiency yourself
