Investing in a new boiler is an important decision for any homeowner in Ireland. Whether you're upgrading your current system or installing a brand-new boiler, understanding the cost of a new boiler is essential before making a purchase.
Average Cost of a New Boiler in Ireland
The average cost of a new boiler in Ireland ranges from €2,500 to €4,000, which includes both the boiler unit and the installation costs. However, several factors can influence the final price, including the type of boiler, the size of your home, and the number of radiators that need to be connected.
Factors Affecting the Cost of a New Boiler:
Boiler Type: The type of boiler you choose, whether it’s a combi boiler, system boiler, or regular boiler, will impact the price. Combi boilers tend to be more cost-effective, while system boilers and regular boilers might incur additional installation costs.
Home Size: The larger your home, the higher the capacity boiler you’ll need, which may increase the installation costs.
Radiators: If you have more radiators or require additional fittings, the cost will be higher.
Boiler Replacement: If you need to replace an existing boiler, this may involve extra costs, such as disposal fees and plumbing modifications.

The average cost of a new boiler in Ireland ranges between €2,500 and €4,000. This includes both the cost of the boiler and the installation. However, several key factors affect the final price:
Boiler Type: The type of boiler you choose (combi, system, or conventional) plays a big role in the overall cost.
Home Size: Larger homes with more radiators require larger boilers, which increases both the cost of the unit and the installation.
Replacing an Existing Boiler: If you need to replace an existing system, additional costs such as disposal fees may apply.
At Freeman Plumbing Services, our team of RGII Registered engineers can guide you through these considerations, ensuring you select the most cost-effective solution for your home or business.
Boiler Types and Their Impact on Cost
1. Combi Boilers: These are the most popular and cost-efficient option for many Irish homes. They provide both heating and hot water without needing a separate water tank, making them ideal for smaller homes. Combi boilers tend to be more affordable to install due to their compact design.
2. System Boilers: Popular for larger homes or properties with multiple bathrooms, system boilers are a bit more expensive but provide a higher output and more reliable hot water delivery.
3. Conventional Boilers: Though less common today, conventional boilers can be the most expensive to install due to the need for a separate hot water cylinder and additional components. However, they remain a good option for larger homes with high hot water demands.
Factors Affecting the Cost of Your New Boiler Installation
Home Size: Larger homes require higher-capacity boilers, resulting in higher overall costs. Smaller homes may be able to opt for a more compact, cost-effective model.
Radiators and Bathrooms: The number of radiators and bathrooms in your home can affect the size of the boiler you need, influencing both boiler and installation costs.
Existing Boiler Replacement: If you are replacing an old boiler, extra costs for removal and disposal will apply. Replacing an old, inefficient boiler can also save you money in the long run through improved energy efficiency.
Cost of Converting from a Regular Boiler to a Combi Boiler
Upgrading from a regular boiler to a combi boiler is a popular option for many homeowners looking to increase energy efficiency and save on their energy bills. Here’s an overview of what to expect when converting:
Cost of Materials
The cost of a combi boiler can range from €1,500 to €3,500, depending on the brand, model, and features. While combi boilers are generally more expensive upfront, they offer greater efficiency, which results in long-term savings.
Cost of Installation
The installation of a combi boiler requires a more complex setup than a standard boiler, so installation costs can range from €2500 to €5,000. This can vary depending on the complexity of the installation and the state of your existing system.
Total Conversion Cost
Taking into account the materials and installation, the total cost to convert from a regular boiler to a combi boiler in Ireland typically ranges from €4,000 to €7,500.
Upgrading to a combi boiler not only saves space but also offers better energy efficiency. If you’re thinking about converting, our Gas Safe engineers can provide an accurate estimate and guide you through the process.
Factors Affecting the Cost of Boiler Replacement
If your boiler is old, inefficient, or broken, replacing it can improve the comfort of your home and lower your energy bills. Several factors influence the cost of boiler replacement:
Boiler Type: Whether you’re replacing a gas boiler, oil boiler, or electric boiler, the type of system will determine the cost. Gas boilers tend to be the most expensive, while electric boilers are often more affordable but less common.
Boiler Size: Larger homes need more powerful boilers, which means higher initial costs. However, investing in a larger boiler can lead to significant long-term savings in fuel efficiency.
Installation Complexity: Installation costs vary depending on the complexity of the job. If your home requires plumbing or electrical work to accommodate a new system, this can increase costs.
Fuel Costs: The type of fuel your boiler uses will also impact running costs. Gas boilers generally have lower operational costs compared to electric boilers.
Efficiency Ratings
Choosing a highly efficient boiler may increase the upfront cost, but it can result in savings on your energy bills over time. More efficient systems have higher SEER (Seasonal Energy Efficiency Ratios) and SAP (Seasonal Average Efficiency) ratings, helping you save money on gas or electricity consumption.
Age of Your Current Boiler
Older boilers are less efficient and more likely to break down, resulting in higher maintenance costs. Replacing an old boiler with a new A-rated system can significantly reduce fuel usage, saving you money in the long run.
