When it comes to choosing a new boiler for your home, the number of options available can feel overwhelming. The three main types – combi, system, and conventional boilers – each have their own advantages and are suited to different household needs. In this guide, we’ll compare these boiler types to help you make an informed decision about which is best for your home.
Combi Boilers – Compact and Efficient
Combination boilers, or combis, are the most popular choice for modern homes. They provide hot water on demand without the need for a separate water tank, making them an excellent option for homes with limited space.
Pros of a Combi Boiler:
✔ Space-saving – No need for a hot water cylinder or cold-water storage tank
✔ Energy-efficient – Only heats water when required, reducing energy waste
✔ Faster hot water – No waiting for a tank to heat up
✔ Lower installation costs – Fewer components mean simpler installation
Cons of a Combi Boiler:
✘ Limited hot water supply – Can struggle with high demand if multiple taps/showers are used at once
✘ Not ideal for large homes – Better suited for smaller households with one or two bathrooms
System Boilers – Great for Larger Homes
System boilers are a middle ground between combi and conventional boilers. They heat water directly from the mains and store it in a hot water cylinder, making them ideal for homes that require hot water in multiple places simultaneously.
Pros of a System Boiler:
✔ Strong water pressure – Great for homes with multiple bathrooms
✔ No cold-water storage tank – Frees up space compared to conventional boilers
✔ Efficient for larger households – Provides hot water to multiple outlets at once
Cons of a System Boiler:
✘ Requires a hot water cylinder – Takes up space in an airing cupboard or similar location
✘ Hot water isn’t instant – The cylinder must be heated in advance
✘ Potential heat loss – Stored water can lose heat over time, increasing energy usage
Conventional Boilers – Traditional and Reliable
Conventional boilers, also known as regular or heat-only boilers, are the most traditional type and are often found in older homes. They require both a hot water cylinder and a cold-water storage tank, typically located in the loft.
Pros of a Conventional Boiler:
✔ Good for high water demand – Can supply multiple bathrooms simultaneously
✔ Compatible with older heating systems – Ideal for homes with existing radiators and pipework
✔ Works well with solar thermal systems – A more eco-friendly option
Cons of a Conventional Boiler:
✘ Takes up space – Requires both a cylinder and a cold-water tank
✘ Slow heating process – Hot water isn’t always available on demand
✘ More complex installation – Typically more expensive to fit than a combi or system boiler
