Boiler Types We Install
Understanding the different boiler types helps you make the right choice for your home. Our company, Heat Knights, we install all major boiler types across London properties from compact flats to large family homes.
Combi Boilers
The most popular choice for London homes, combi boilers provide both central heating and instant hot water from a single compact unit. There’s no need for a separate hot water cylinder or cold water tank, making them ideal for flats and smaller properties where space is at a premium.
Modern combi boilers are highly efficient, with many achieving over 90% energy efficiency ratings.
System Boilers
System boilers work with a separate hot water storage cylinder, making them a great option for homes with higher hot water demand; such as larger households with multiple bathrooms.
They’re neater than traditional boilers because most components are built into the unit itself, and they can supply hot water to multiple taps all at once.
Conventional Boilers
Also known as regular or traditional boilers, these are best suited to older properties with existing pipework designed for this setup. They require both a hot water cylinder and a cold water storage tank.
While less common in new installations, Heat Knights can smoothly replace like-for-like in properties where a conventional boiler is the appropriate solution.
Benefits of New Boiler Installation
Replacing an old, inefficient boiler with a modern unit brings a range of immediate and long-term advantages:
- Lower Energy Bills: Older boilers can operate at efficiencies as low as 60–70%, meaning up to 40p in every £1 you spend on heating is wasted. A new A-rated condensing boiler operates at 90%+ efficiency, which can translate to savings of hundreds of pounds per year on your gas bill.
- Improved Home Comfort: Modern boilers respond faster, heat your home more evenly, and provide consistent hot water pressure. No more cold spots, no more waiting for the hot water to arrive, and no more unreliable heating on the coldest days.
- Reduced Carbon Footprint: A more efficient boiler means burning less gas to achieve the same level of warmth. This directly reduces your household’s CO₂ emissions — a meaningful step toward greener living.
- Enhanced Safety: Older boilers are more prone to faults, including carbon monoxide leaks — a silent, potentially fatal risk. A new installation comes with modern safety controls and is fully compliant with current UK Gas Safe regulations.
- Increased Property Value: A new boiler is a selling point. Estate agents and buyers alike recognise that a recently installed, efficient boiler reduces the risk of unexpected repair costs and signals a well-maintained home.
- Manufacturer Warranty: New boilers typically come with manufacturer warranties of 5 to 10 years, giving you peace of mind and protection against unexpected repair bills.
