Before diving into sizing, it’s essential to understand the main types of boilers available on the market:
1. Combi Boilers (Combination Boilers)

No need for a separate hot water cylinder or cold-water storage tank.
Downside: May struggle in homes with multiple bathrooms running hot water simultaneously.
2. System Boilers
Best for: Medium to large homes with higher hot water demand.
-
Requires a hot water cylinder but no cold-water storage tank.
-
Can provide hot water to multiple taps at once.

More energy-efficient than traditional systems.

3. Conventional Boilers (Regular or Heat-Only Boilers)

Boiler Sizing: Matching Your Boiler to Your Home Size
One of the most common mistakes homeowners make is choosing the wrong boiler size. Boiler size doesn’t refer to the physical dimensions but the output in kilowatts (kW) – essentially how much heat it can generate.
Here’s a quick breakdown of boiler sizing based on home size:
1. Small Homes or Apartments (1–2 bedrooms)
-
Recommended: Combi boiler (24–27 kW).
-
Ideal for one bathroom and low-to-moderate hot water usage.
2. Medium Homes (3–4 bedrooms)
-
Recommended: System or combi boiler (28–35 kW).
-
Suitable for families with moderate hot water needs and possibly two bathrooms.
3. Large Homes (4+ bedrooms, multiple bathrooms)
-
Recommended: System or conventional boiler (35–42 kW).
-
Designed to handle high demand for heating and hot water simultaneously.
4. Very Large Properties or Commercial Use
-
Recommended: Conventional or multiple boilers installed together.
-
Ensures reliable heating for extensive space and heavy water usage.
Key Factors to Consider When Choosing the Best Boiler
When deciding which boiler is right for your home, keep the following factors in mind:
1. Heating and Hot Water Needs
Consider how many people live in your home and how often hot water is used. A couple in a small apartment may be fine with a combi boiler, while a large family with three bathrooms will need a more powerful system.
2. Energy Efficiency
Look for boilers with an A-rated efficiency score. Modern condensing boilers are up to 90–95% efficient, meaning more heat is generated from the same amount of fuel.
3. Available Space
If space is limited, a combi boiler is your best option since it eliminates the need for tanks. If space is not an issue, a system or conventional boiler may be more suitable.
4. Fuel Type
-
Gas boilers are the most common and cost-effective.
-
Electric boilers are great for homes without gas access.
-
Oil boilers are often used in rural areas.
-
Renewable energy options like biomass boilers or hybrid systems may also be considered.
5. Budget and Installation Costs
While it’s tempting to go for the cheapest option, think long-term. A slightly higher upfront investment in an efficient boiler can save you thousands in energy bills.
