Upgrade your Boiler

If your oil boiler is more than six years old, replace it with a modern condensing model. This will significantly improve your energy efficiency and save you a lot of money! We calculate that it could save you over £200 a year and it will also dramatically reduce carbon emissions, which is good for the environment. Condensing boilers recover waste heat that normally passes out of the flue into the air in a conventional boiler. Oil condensing boilers have efficiencies of up to 97% while older boilers are typically 60 - 70% efficient. We recommend that you talk through the options with your local OFTEC heating technician and discuss what would work best for you.

Oil condensing boilers are one of the options included in the government’s Energy Company Obligation (ECO) scheme, which provides a way to fund energy efficiency improvements at minimal upfront cost.
