Choosing the Right Boiler When Replacing Your Old Gas Boiler
When it comes to replacing an existing gas boiler, you have several options depending on your home, lifestyle, and budget.
Combination Boilers (Combi)
- Heat your central heating and hot water directly from the boiler.
- No need for a separate hot water cylinder – saving valuable space.
- Best suited for smaller homes or households with one bathroom.
- Highly energy-efficient, with minimal heat loss.
Ideal for: Flats, apartments, and small to medium homes where space is limited.
System Boilers
- Take water directly from the mains and store it in a hot water cylinder.
- Provide a constant supply of hot water to multiple taps at once.
- More suited to medium or larger homes with higher hot water demand.
Ideal for: Families with multiple bathrooms and higher daily hot water use.
Regular Boilers (Conventional)
- Also known as traditional or heat-only boilers.
- Use a separate hot water cylinder and cold water storage tanks (typically in the loft).
- Best for homes with an existing traditional heating setup.
Ideal for: Larger homes already configured for a regular boiler setup or households with very high hot water needs.
Should You Switch Boiler Type When Replacing Your Gas Boiler?
When replacing your boiler, you can either:
- Replace ‘like-for-like’ – e.g., install a new regular boiler to replace an old one.
- Upgrade to a different type – e.g., replace an old conventional boiler with a space-saving combi.
Factors to consider:
- Hot Water Usage – Larger families benefit from a system or regular boiler. Smaller households are often better off with a combi.
- Space Availability – Combi boilers free up valuable space by eliminating hot water tanks.
- Budget – Some conversions (e.g., regular to combi) involve additional work and cost but may deliver long-term savings.
