Gas Boilers for 3 Bedroom Homes.
One of the most common home types in Ireland, your typical 3 Bedroom home will have between 7-9 radiators and require a gas boiler with an output of around 18kW. This will of course depend on your homes existing radiator outputs.
The radiators will usually consist of single panel lower output radiators in the 3 bedrooms and upstairs bathroom, with double panel higher output radiators in the downstairs hall, kitchen, dining room and living room.
This home type may be terraced, semi-detached, bungalow type or duplex type property, if your property is fully detached or larger than 120m2 you may require a higher output gas boiler.

Gas Boilers for 4-5 Bedroom Homes.
Large homes up to 2,200 will require large boilers, this is true except for homes that have exceptional levels of heat retention.
A new energy efficient boiler with an output of 30kW will most likely be required for a large 4-5 bedroom home with no more than 16 Radiators
Another consideration to be given is hot water! Large homes will normally have more bath and shower rooms resulting in higher demands for hot water. It is for this reason a standard combi boiler would not be recommended for a property of this size.

Gas Boilers for Very Large Homes. (35kW - 50kW)
Which boiler is best for those very large homes? Homes that exceed 2,200 sq ft may well require a boiler with an output of at least 35kW, and possibly even higher depending on size.
At 35kW, this is the cut off point for system boilers, if you require a higher output than 35kW your boiler will be a regular type boiler.
It is best to talk to heating engineer for property’s exceeding 2,200 as it is quite common for boilers to be under or oversized.

Combi Gas Boilers
Combi Gas boilers are an excellent choice for smaller properties with low hot water demands. They provide instant hot water on demand improving your home lifestyle and increasing your homes efficiency.
Although quite capable of providing hot water to small homes for showering etc. If you have multiple bath or shower rooms a combi boiler may not be suitable option, as it is limited in the amount of hot water it can produce instantly.

Hydrogen Ready Gas Boilers
The Boilers listed are all Hydrogen Ready making them excellent choices for meeting your homes future heating requirement.
A hydrogen boiler is a type of boiler that burns hydrogen instead of natural gas (methane). It functions similarly to natural gas boilers by utilizing combustion to generate hot flue gases, which are then used to heat water. The hot water can be stored and circulated through radiators to provide warmth to your home.
While hydrogen boilers operate similarly to conventional boilers, certain components, such as the flame detector and burner, may differ slightly due to hydrogen being a thinner gas than methane. However, the overall functionality remains the same as your current boiler.
It's important to note that hydrogen boilers should not be confused with boilers that utilize hydrogen fuel cells or hydrogen-ready boilers, as these are distinct systems.
In contrast to hydrogen boilers and boilers with hydrogen fuel cells, a hydrogen-ready boiler (20% blend) is designed to burn both natural gas and hydrogen. This means that when the gas network transitions from methane to hydrogen, there will be no need to replace the existing gas boiler. The viability of this approach is still under research and development but is expected to support overall decarbonization efforts. Solutions are being explored to enable heating engineers to convert products with this capability.
When hydrogen is eventually introduced into the gas network, it is likely to be phased in gradually rather than an immediate switch from natural gas to hydrogen. The HyDeploy program, currently being conducted at Keele University, is testing the effects of using a blend of hydrogen and natural gas. With a 20% hydrogen and 80% natural gas blend, most boilers would require no modifications, allowing for a swift transition. The aim is to achieve this by 2025.
How do hydrogen-ready boilers work and when will they be available?
Currently, fully functional 100% hydrogen boilers are not available as the technology is still being developed. However, some major boiler manufacturers have created prototypes.
Here's a breakdown of how hydrogen-ready boilers operate:
- Oxygen and hydrogen enter the boiler: Oxygen and hydrogen are supplied to the main boiler unit. Hydrogen is sourced from the gas supply (when available), while oxygen is obtained from the air. A gas inlet valve controls the gas mixture, which is crucial as it determines the flame's size.
- Mixing and combustion: The hydrogen and oxygen gases are mixed and ignited in a catalytic burner. Hydrogen has higher flammability than natural gas, so the burners are specially designed to limit the flames in case of excessive gas flow. Detection components are necessary in hydrogen-only boilers as hydrogen flames are invisible.
- Heat exchange: The hot flue gases produced by combustion enter the heat exchanger, consisting of pipes through which cold water flows. As the hot gas passes through the pipes, it heats the surrounding water, which can then be used for heating systems or supplied to hot taps.
- Byproduct release: The only byproduct of burning hydrogen and oxygen is water, requiring a condensate system for its removal. The hot flue gases, along with some NOx emissions resulting from hydrogen combustion, exit the system through the flue.
The hydrogen boiler continues to draw in hydrogen and oxygen, allowing the process to repeat.
Will gas boilers be replaced by hydrogen?
With the government's ban on gas boilers in new build properties starting in 2025, heat pumps and hydrogen boilers are potential alternatives. However, currently,
