Gas Boiler Replacement

Old gas boilers waste energy and are costly to run, as a large portion of the heat is lost up the flue/chimney. The latest condensing boilers use fuel more efficiently, potentially saving you up to 20%** on your home heating bill.

If you have an old boiler its operational efficiency could be as low as 60%** efficiency. You can increase it to up to 90%* *by installing a new high efficiency condensing boiler. You may even find that you can comfortably install a smaller boiler, further reducing your fuel bills. There is a potential SEAI grant to help with the cost works.
