Combi gas boilers

Combi Boiler Installation In Dublin

Replacement Combi Boilers With Duffy Heating

Trust us – a gas combi boiler is a real game-changer when it comes to heating your home and hot water. And with SEAI approved central heating grants available, fitting a modern new boiler with Duffy Heating will be great for both the environment and your bank balance.

What Is A Combi Boiler?

A combi boiler (short for combination) is a compact unit that takes care of both your heating and hot water.

It draws water directly from the mains and passes it through a heat exchanger, giving you instant, mains-pressure hot water.

At Duffy Heating, we install and service gas combi boilers in Dublin and the surrounding area – and we’ve always been really impressed with their reliability and performance.

What Are The Benefits Of A Combi Boiler?

There are many benefits in switching to a combi boiler. Here’s a quick look at how replacing your old boiler with a new combi boiler can help you, your household – and the environment:

  • A new combi boiler will save you money. Typically, a new boiler is 30-40% more efficient than an old-style non-condensing boiler. Based on the average Irish household gas bill of €727, you could save over €400 a year.

  • A combi boiler is better for the environment. An older boiler is only 60-70% efficient, which means it’s wasting an awful lot of energy. A new combi boiler is 90%+ efficient giving it an A rating.

  • Heating and hot water are controlled separately. You’ll no longer need to fire up the whole system just to run a quick bath. That’s a real money-saving benefit.

  • You can set up separate heating zones. Different rooms need to be at different temperatures at different times. Some rooms (like a spare bedroom) rarely need heating at all. A new digital control system will let you set up the heating to suit your home and lifestyle.

  • There’s instant hot water. No more running out of warm water in the shower, or heating up unneeded water. And because the water is mains-fed and heated on demand, there’s no need for a water cylinder or tank.

  • There’s an app-controlled option. Some combi boilers are compatible with a heating app. This means you can control your heating and hot water remotely, via your smartphone, tablet or computer.
