Here’s What Boiler Installation Should Cost You
Understanding boiler installation costs is essential when planning to replace your heating system. Whether you're upgrading an outdated unit or switching to a more efficient system, knowing what to expect financially helps you make informed decisions. This guide breaks down the various factors that influence boiler installation costs in Ireland, from the type of boiler you choose to additional installation requirements that might affect the final price.
Factors Affecting Boiler Installation Cost
The cost of installing a new boiler depends on several key factors. The type of boiler (combi, system, or conventional) significantly impacts the price, with combi boilers typically being the most popular choice for Irish homes due to their efficiency and space-saving design. The boiler’s size and output rating, measured in kilowatts (kW), must match your home’s heating and hot water demands. Additionally, the brand you select affects costs, with premium manufacturers like Worcester Bosch or Vaillant generally commanding higher prices than budget options. The complexity of your installation also plays a role – a straightforward replacement typically costs less than relocating a boiler to a new position in your home.
Average New Boiler Cost Including Installation
In Ireland, the cost of a new boiler including installation typically ranges from €2,000 to €5,000. Combi boilers, which provide both heating and hot water on demand without a separate tank, usually cost between €2,000 and €3,500 installed. System boilers, which work with a hot water cylinder but don’t require a cold water tank, generally range from €2,500 to €4,000 installed. Conventional boilers (also called regular or heat-only boilers), which work with both a hot water cylinder and cold water tank, typically cost between €2,300 and €3,700 installed. These prices reflect standard installations and can increase if additional work is required, such as moving the boiler location or updating pipework.
Cost Comparison: Gas vs. Oil vs. Electric Boilers
The fuel type of your boiler significantly impacts both installation costs and long-term running expenses. Gas boilers are the most common in Ireland and typically cost between €2,000 and €3,500 installed. They offer relatively low running costs but require connection to the gas network. Oil boilers generally cost between €2,500 and €4,500 installed and need space for an external oil storage tank, adding to the installation footprint. Electric boilers are the easiest to install, costing between €1,800 and €2,800, but have higher running costs than gas or oil options. When choosing a fuel type, consider both the upfront installation costs and the ongoing operational expenses based on current energy prices in Ireland.
Replace Boiler with Tankless Water Heater: Cost Analysis
Switching from a traditional boiler to a tankless water heater (also known as an instantaneous or on-demand water heater) is becoming increasingly popular in Ireland. These systems heat water directly without using a storage tank, providing hot water only as needed. The cost to replace a conventional boiler with a tankless system typically ranges from €1,500 to €3,000 for electric models and €2,500 to €4,500 for gas-powered units. While the installation cost may be comparable to traditional boilers, tankless systems offer space savings and potential energy efficiency benefits. However, they may require electrical upgrades or gas line modifications, which can add to the overall installation cost.
Additional Costs to Consider When Installing a New Boiler
Beyond the basic installation, several factors can add to your total expenditure. System flushing and cleaning (€300-€500) is often necessary to remove debris and sludge from existing pipework. Adding a magnetic filter (€100-€200) helps protect your new boiler from damage caused by circulating debris. Smart thermostats and controls (€150-€350) improve efficiency but add to upfront costs. If your installation requires relocating the boiler, expect to pay €300-€700 extra for extended pipework and labor. Additionally, removing an old boiler costs around €100-€200, while updating to current building regulations could add €200-€500 for items like condensate drainage improvements.
Boiler Installation Cost Comparison by Type and Brand

Long-Term Savings and Investment Considerations
While the initial cost of boiler installation may seem substantial, it’s important to consider the long-term savings a new, efficient system can provide. Modern A-rated boilers can be up to 90% efficient, potentially saving you hundreds of euros annually on heating bills compared to older models operating at 70% efficiency or less. Most new boilers come with warranties ranging from 2 to 10 years, providing peace of mind regarding repair costs. When evaluating your investment, consider the annual fuel savings against the installation cost. Higher-efficiency models and those with longer warranties may cost more upfront but often deliver better value over the boiler’s lifespan, which typically ranges from 10 to 15 years with proper maintenance.
