What is a Combi Boiler
A Combination boiler, also known as a combi boiler is a popular boiler choice for small to medium sized homes throughout Ireland. The main advantage of a combi boiler is the capability to heat the domestic hot water on demand. While at the same time meeting the property's heating requirements.
It does all this without the need for bulky hot water storage cylinders and tanks, Gas Combi boilers are available for both LPG and Natural Gas, with models also available for oil fired and electrical heating systems.
Why Choose a Combi Boiler?
Although combination boilers are not the popular boiler choice in Ireland. There are several reasons why choosing a combi boiler makes perfect sense.
Ideal for apartments and smaller homes, they offer space saving benefits when compared to traditional heating boiler systems. With no bulky hot water cylinder required.
They produce hot water on demand, meaning there's waiting around for the water to heat. Removing the need to worry about timers or immersion heaters. This will also reduce energy wastage as you only heat what you use.
Like pressure?. In Ireland poor water pressure is a common occurrence. Combination boilers operate at a higher pressure than traditional gravity feed hot water systems. Resulting in more flow at the tap.
As much as you may like the idea of instant hot water, combi boilers are not an ideal fit for every home.
If your home is quite large with several bathrooms, en-suites etc a combination boiler may not be the right choice. One of the most common combi problems we encounter is the lack of hot water when more than one hot water outlet is in use. Because combi's heat the water instantly, the amount of hot water produced may not be able to keep up with demand. For example, if you have more than 1 shower operating at the same time. Because of this combi boilers are not recommended for homes with more than one bathroom.
Mains Water Pressure.
The incoming water mains is not sufficient or erratic. Because combi boilers require a min flow rate to operate, if your mains water is to weak a booster pump and break tank will be required. This will increase installation and maintenance costs

Combi Boilers Vs Regular Boilers
Pros & Cons of a Combi Boiler
For the average small sized homes with 1 bathroom, a combi boiler offers several advantages:
- Efficient: Combi boilers provide hot water on demand, eliminating the need to heat and store a cylinder of water constantly. This makes them highly efficient.
- Energy-saving: Heating water only when needed reduces energy consumption, making combi boilers more eco-friendly and cost-effective.
- Space-saving: Combi boilers are compact and consist of just one unit, fitting well in most kitchens and can even be concealed behind cupboards.
- Cost-effective: The on-demand heating method saves energy, leading to lower heating costs over time.
- Easier Repairs: Spare parts for modern combi boilers are often readily available, simplifying and speeding up the repair process.
- Not Suitable for Larger Homes: Combi boilers may struggle to meet the high demand for hot water in larger homes.
- Dependent on Mains Water Pressure: Homes with weak mains water pressure may not be suitable for combi boilers.
Pros & Cons of a System/Regular Boiler
For larger homes with more than 1 bathroom a system/regular boiler offers its advantages and disadvantages:
- Meets High Demand: Conventional boilers can supply multiple areas of the home with hot water simultaneously, keeping up with high demand.
- Well-suited to Larger Homes: Larger homes with existing conventional boiler systems may find it more cost-effective to maintain rather than replace them.
- Requires Space: Conventional boilers require ample storage and installation space, including insulation to prevent heat loss.
- Delayed Hot Water: Users may experience delays in accessing hot water if the cylinder runs out and needs reheating.
- Complex Maintenance: Conventional boilers have more components and controls, requiring regular maintenance and posing potential risks of leaks and damage.
Costs of Converting to a Combi Boiler from a System/Regular Boiler
Converting from a conventional to a combi boiler can cost between €3,500 and €4,800, including the installation of a reputable brand like Worcester Bosch. While the initial cost may be high, the long-term benefits include improved efficiency and lower energy bills.

What Size Combi do you need?
Choosing the Right Boiler Size for Your Home
When it comes to selecting the right boiler size for your home, there are several factors to consider, including your hot water needs, the size of your home, and the number of radiators. Here's a breakdown to help you find the perfect fit:
2 Bedroom Homes/Apartments
- Ideal for individuals or small families living in homes or apartments with one to two bedrooms, one bathroom, and up to ten radiators.
- Choose a combi boiler with an output between 24-30kW to meet your heating and hot water needs efficiently.
3 Bedroom Homes:
- Suitable for medium-sized semi-detached houses with three to four bedrooms, one to two bathrooms, and up to 14 radiators.
- Consider a boiler with an output between 30-35kW to ensure ample heating and hot water supply for your household.
Large 4-Bedroom Homes:
- Perfect for large families with high hot water demand residing in spacious semi-detached or detached houses with over four bedrooms, over two bathrooms, and up to twenty radiators.
- Choose a Combination boiler with an output of 35-40kW to meet your homes heating and hot water needs effectively.
Count Your Radiators:
- Counting the number of radiators in your home can help determine the appropriate boiler size. Generally, more radiators require a larger boiler to provide sufficient heating power.
- For example:
- Up to 10 radiators: 24–27 kW
- 10 to 15 radiators: 28–34 kW
- 15 to 20 radiators: 32–40 kW
Oversizing your boiler can lead to wasted energy and higher fuel bills. Choose a boiler size that meets your needs without excess capacity.
5 Important Factors
What are five most important factors in your decision-making process?
Price, Efficiency, Warranty, Reliability, Quality Installer are probably the most influential factors to decide from.
The single most important decision is the cost. Prices can vary hugely, depending on the installation difficulty and choice of boiler. It is for this reason it is important to get at least 3 estimates.
With so many different boilers brand available on the market today it may be difficult to decide which is best. Although a certain brand may be very popular in Ireland, this does not guarantee quality. Think Celtic Tiger Houses, the most important factor for many builders was maximum profits. Nobody ever questions the central heating boiler when buying a brand-new house. But you Should!
The longer the warranty the better the deal and usually the better the boiler. It is important to ensure that any warranty given is backed up by the boiler manufacturer. Ensure you receive a copy of the warranty documentation including all relevant terms and conditions.
The better the reliability the better the boiler. Worcester Bosch are the market leaders when it comes to reliability. But don’t believe us check it out for yourself here
Although manufacturer accredited installers are always the best choice. It is important to research online reviews to ensure they are both genuine and positive. Don’t be afraid to ask for references if your still unsure. RGI Registered is not only a must its illegal for anyone other than an RGI.
The level of insulation in your home impacts its heating efficiency. Poor insulation may necessitate a higher output boiler.
The amount of hot water your home uses will have a direct impact on the required boiler size. Likewise, the heating demands for your home will also have a bearing on the boiler size.
The bigger the hot water output, the higher the flow rate. It is important to remember the incoming cold mains water pressure, will also need to be capable of matching the flow rate output of the boiler.
With so many different factors affecting the boiler size, it is best to seek expert advice.

Deciding on Boiler Brand
Types of Combi Boilers in Ireland
Although we’ve listed the best gas Combi boilers here as they’re the most commonly installed, Combi boilers are also available in oil, LPG or electric in a range of sizes.
Gas Combi Boilers
Natural Gas Combi Boilers are the most popular combi boiler sold in Ireland. Natural Gas is a cheaper fuel when compared with electricity, oil or LPG. This of course means lower running costs.
For Nat Gas Boiler Installations always consult an RGI Registered Installer
Oil Combi Boilers
Much like their natural gas counterparts oil combi boilers never really took off in Ireland. Although scarce, they do exist. When compared to gas, with oil combis you can expect to pay as much as 40% more in installations costs. Not to mention the running costs will be typically more expensive too. Not forgetting if you are unfortunate to run out of oil, you will be without hot water. Although an inline immersion can be fitted as a backup. This will not provide the equivalent in hot water.
For Oil Boiler Installation always consult an OFTEC Registered Installer
LPG Combi Boilers
Very much the same as natural gas combi boilers, with running costs the main difference. Although costlier per unit than Nat Gas, for homes not on the national gas network LPG may be a wise choice. Liquid Petroleum Gas is available in both bulk storage and bottled supply.
For LPG Gas Boiler Installations always consult an RGI Registered Installer
Electric Combi Boilers
An electric Combi boiler uses an electrical element to heat the water. They are a popular choice for homes where Nat Gas, LPG or Oil is either unavailable or inpractical.
The most obvious downside to electrical boilers is of course the usage costs, which are considerably more than alternative fuels. Electrical boilers are not suited to homes with moderate hot water needs.
Choosing an Installer
Installation of a combi boiler is a complex specialist task that requires competent engineers/plumbers and in some cases electricians. In Ireland there is plenty of boiler installation companies to choose from. But How do you choose between them?
