A new gas boiler will cost between €2,000 and €4,000 depending on the make and model. Gas boilers work by heating water that is then used as part of your central heating system or as a source of hot water for baths, showers and radiators. It's recommended that you have your gas boiler serviced once a year to keep it working efficiently. Always use an RGII registered gas installer when having any work done on your gas boiler.
A new gas boiler in Ireland will typically cost between €2,000 and €4,000. The gas boiler price depends on the following variables:
The size of your home will dictate the size of boiler you need and thereby its cost. Below, you'll find a comparison of the estimated price of a gas boiler based on its size:
| Size of Home | Boiler Size | Estimated Price |
|---|---|---|
| One to Two Bedrooms | 15–18 kW | €2,500 |
| Two to Three Bedrooms | 18–24 kW | €2,800 |
| Four to Five Bedrooms | 30 kW | €3,000 |

As we can see from the table above, for smaller homes and apartments, a 18kw gas boiler would be sufficient while for larger homes, it would be better to invest in a larger boiler bigger than 20kw.
Are There Gas Boiler Grants in Ireland?
No. There are no longer boiler grants available in Ireland. The government is also planning on phasing out gas and oil boilers by 2025. However, there are grants available from the SEAI for heat pumps and solar water heaters.
Given that the individual expectations, and budget, of someone purchasing a new gas boiler will be different, it's difficult to give a definitive recommendation as to which is the best boiler available on the market.
What we can advise is the factors to take into consideration before buying a new boiler. By having an idea of this, you will be better placed to compare what is available on the market.
Factors to consider include:
Below you will find an overview table of some popular gas boiler brands and their estimated price range:
| Brand | Estimated Price Range (EUR) |
|---|---|
| Worchester Bosch | €2,500 - €3,500 |
| Vaillant | €2,500 - €3,500 |
| Viessmann | €3,000 - €4,000 |
| Ideal | €2,000 - €3,000 |
| Baxi | €2,000 - €3,000 |
Gas boilers are similar in cost to oil but given that electricity is always more expensive than either of the other two, it will always be the most expensive means of heating a home.
Having said that, there are several factors that impact on the total cost of heating a home regardless of which type of boiler you have, including:
The following table gives a basic breakdown of the difference in price between the three types of boilers and which will be phased out completely in the future.
| Boiler | Price | Cost per day | Will Be Phased Out? |
|---|---|---|---|
| Electric | €600 - €1200 | €12 to €20 | ❌ |
| Gas | €1500 - €3500 | €10 to €16 | ✅ |
| Oil | €3000 - €3500 | €13 to €22 | ✅ |

The price for a full gas boiler service can range from €80 to €120 excluding labour costs.
There are several factors that can influence the cost of your boiler service, including:
It is recommended to shop around for two or three quotes before choosing a service, as many operators will offer different rates.
A gas boiler service must be carried out by a Registered Gas Installer (RGI) to ensure that the work is carried out to a high standard of safety.
To find a Registered Gas Installer in your area, you can use the RGII offical website to search for an RGI in your county.
Often issues with your boiler can be fixed at home without the need for a full service such as bleeding your boiler.
Carbon Monoxide Alarms
As gas boilers burn a carbon emitting fuel, there is a risk of carbon monoxide leaking out if the boiler is not properly serviced. Install a carbon monoxide alarm and make sure to keep an eye out for any discolouring on your boiler.
A gas boiler works by burning gas in order to heat water, which is then pumped around your house as part of your home heating system, or for use as hot water in baths, showers, taps etc.
To use a gas boiler, you must be connected to the gas network and be in contract with a gas supplier.
Gas boilers are popular forms of heating homes, in particular urban areas, as gas is normally cheaper than both oil and electricity.
There are three main types of gas boilers available in Ireland:
What is a Condensing Gas Boiler?
A condensing boiler works by condensing water vapour in exhaust gases to recover latent heat that would be otherwise lost, making them highly efficient. All gas boilers are, by law, condensing boilers.
For those with access to the gas network, gas boilers offer an affordable and convenient means of heating their homes when compared to oil, electric or biomass boilers.
Despite this, the fluctuating price of gas can make them more expensive and without regular servicing, their efficiency can diminish over time.
