Gas Boilers for 3 bedroom homes in Ireland

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.

large 4-5 bedroom homes in ireland

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.

Is Upgrading to a New Gas Boiler Worth It?

With the future of gas boilers facing uncertainty, many homeowners wonder if it's worthwhile to invest in a new system.

Here's what you need to know:

  1. Impact of Gas Boiler Ban: Unless you're building a new home, the proposed gas boiler ban in 2025 shouldn't affect your current heating setup. However, there may come a time when you need to replace your boiler due to age or inefficiency.
  2. Consider Your Options: When it's time for a replacement, weigh your options carefully. Compare boiler costs and consider alternatives suited to your property. Keep in mind that not all homes are suitable for heat pumps, especially those lacking proper insulation or with smaller heating systems.
  3. Grants and Incentives: As the shift towards low carbon heating systems gains momentum, expect to see more SEAI grants and incentives aimed at encouraging greener technologies. These initiatives could make low carbon options more appealing over time.

Ultimately, deciding whether to upgrade to a new gas boiler depends on your specific circumstances and long-term heating needs. For personalized advice and assistance in navigating the transition to low carbon heating, reach out to GasWorks.ie. We're here to help you make informed decisions that prioritize efficiency, comfort, and environmental sustainability.

Large House in Ireland

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.

Gas Boiler Ban For Ireland in 2025 Not Likely

In the ongoing discussion about Ireland's proposed ban on gas boilers in new homes by 2025, there are important considerations to keep in mind.

While the aim is to reduce carbon emissions and promote sustainability, there are concerns and challenges associated with completely phasing out gas boilers.

Gas Boilers Offer Cost Effective Heating Solutions.

Gas boilers have been a reliable and efficient heating solution for Irish homes, offering warmth and hot water in a cost-effective manner. They're easy to install, widely available, and have a proven track record of performance. For many homeowners, gas boilers have been essential for comfort and convenience.

However, the transition away from gas boilers raises questions about the availability and suitability of alternative options.

Boiler Reliability tried and tested.

While heat pumps and solar thermal systems are often seen as greener alternatives, they may not be suitable for every home due to factors like upfront costs and technical limitations. Additionally, the reliability and performance of alternatives may not yet match that of gas boilers.

The transition could also impose financial burdens on homeowners, especially those with existing gas boiler systems. Retrofitting homes with alternative heating technologies may require significant investments, potentially straining household budgets.

Rather than an outright ban, a balanced approach that encourages innovation and incentivizes the adoption of cleaner technologies would be preferable.

More than natural gas.

Research into cleaner-burning natural gas technologies, such as hydrogen boilers, could offer a smoother transition path.

In conclusion, while the goal of reducing carbon emissions is important, it's crucial to consider the practical challenges and implications of phasing out gas boilers. Any transition should be carefully planned to ensure minimal disruption and maximum benefit for homeowners and society as a whole.

Hot water from combi used for bath

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.

 

Combi boilers, short for combination boilers, are gaining popularity in the Ireland for their ability to deliver hot water on demand without the need for a hot water tank. They are named "combi" because they can provide both heating and hot water as needed. Let's take a closer look at the pros and cons of combi boilers to help you decide if they're the right choice for your home.

 

The Benefits of Combi Boilers:

1. Very Efficient: Approximately 55% of your annual energy costs are attributed to heating your home. Condensing Combi boilers are highly energy-efficient, boasting efficiency ratings of 90-94%. This means you'll enjoy a warmer home while using less energy, resulting in lower bills.

2. Compact: Combi boilers are more compact compared to traditional systems that require a hot water cylinder. Their smaller size makes them suitable for installation in lofts, utility rooms, or even kitchen cupboards. Some high ourput Combi's can incorporate a tank to provide very high hot water flow rates for homes with greater hot water demands.

3. Instant Hot Water: With a combi boiler, you'll have hot water available instantly whenever you need it. Unlike conventional systems that store hot water in an insulated tank, combi boilers heat water on the spot, ensuring you never run out of hot water.

4. Easy Installation: For new build properties Combi boilers systems are easier and quicker to install compared to conventional boilers because they have fewer external components. The absence of a water tank not only speeds up the installation process but can also reduce installation costs.

 

Drawbacks of Combi Boilers:

1. Relies on Good Mains Pressure: Combi boilers depend on good mains water pressure. If your mains supply has poor pressure, your taps and showers may not function optimally. Consider checking your mains pressure or discussing booster pump options with your installer.

2. No Immersion Heater: Unlike conventional boiler systems, combi boilers do not have an immersion heater. If your combi boiler breaks down, you won't have a backup heating or hot water system until it's repaired.

3. Incompatibility with Power Showers: Power showers, which use separate pumps for strong water pressure, are not compatible with combi boilers. The mains water pressure of combi boilers doesn't support power showers.

4. Limited Hot Water Supply: Combi boilers can supply only a certain amount of hot water at a time. In larger homes with multiple bathrooms, running more than one hot tap simultaneously can result in reduced pressure or cold water. Some combi boiler systems offer solutions, such as internal tanks, to address this issue.

In summary, combi boilers offer energy efficiency, compactness, and instant hot water. However, they rely on good mains pressure, lack an immersion heater, may not support power showers, and have limitations in providing hot water simultaneously in larger homes. Carefully consider your home's size, water demands, and plumbing setup when deciding whether to switch to a combi boiler. Some combi systems, like the Bosch high flow Combi, provide options to address specific needs.

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:

  1. 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.
  2. 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.
  3. 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.
  4. 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,
