Fit An Energy Efficient Combi Boiler Today

Combi boilers keep the home warm and cozy

An old boiler gradually loses its efficiency, and this can equate to over 10% of wasted energy in only a couple of short years.

In addition, if you don’t take care of your boiler or upgrade it to a modern system, any unexpected breakdowns could mean an emergency callout that will cost way more than a simple annual service.

That’s why all Dublin residents should get the latest, fuel efficient combi gas boiler fitted and keep it regularly maintained by a qualified heating professional. Your modern, well serviced combi boiler will create less harmful emissions too, so you’ll not only save money but protect the environment as well.

Grants For Heating Control Improvements

If you live in Dublin and still have an outdated central heating system, with an old mechanical time switch that means you have to heat up the radiators when you only need hot water - then it’s definitely time to upgrade.

If you haven’t upgraded yet then you’re leaving money on the table. You can make huge savings by only burning your gas or oil when and where you really need it. A central heating upgrade means you have independent control over your hot water and heating - so you can enjoy just the right temperature in each room of the house at different times of the day.

At Duffy Heating, we help Dublin residents get money-saving grants for their new boiler and heating controls upgrades, meaning it’s a complete no-brainer to get started today.

With grants available from SAIE’s Better Energy Homes scheme, you can save up to 30% of your annual heating bill with a heating controls upgrade - making you feel more comfortable in your own home at much less expense.

So with nothing to lose and so much to gain, contact Duffy Heating today and our experts will be happy to help you.
