Gas Boiler Replacement In Dublin

Replace Your Boiler & Stop Wasting Gas

If you’re a Dublin resident suffering with an old or faulty boiler, then a gas boiler replacement can make your heating up to 30% more efficient.

As boiler installation experts with years of experience, we can install your new model with the minimum of disruption and hassle - and we promise to have your central heating up and running again quickly and efficiently.

All new boilers must operate with a minimum 90% fuel efficiency, meaning they convert up to 30% more gas or oil into heat. This means you can save money while also doing your bit for the environment - because your new boiler will emit a third less CO2.
The top quality boilers we install also come with a manufacturer’s warranty of at least 5 years, so provided your boiler is serviced every year you won't have to spend a penny on repairs. So fitting a new boiler with the specialists at Duffy Heating is a good choice on many levels.

Gas Boiler Replacement Costs

According to Bord Gais an average household's yearly gas consumption is €727, meaning you can save up to €400 worth of gas a year on just your boiler replacement alone.

Combining your boiler replacement with heating control upgrades means savings can be much higher - and we’ll help you cover part of these costs by securing a SEAI Better Energy Homes Grant for your new heating controls installation. Duffy heating is fully registered with SEAI, meaning you can obtain a grant for all eligible work carried out by us.
