Boiler Types

Helping You Choose the
Right Boiler for Your Home

Selecting the right boiler is essential for efficiency, comfort, and long-term reliability. Delta Gas Installations Ltd installs all major boiler types, ensuring every customer receives the best system for their property and lifestyle.

Combi Boilers

How they work:

Combi boilers heat water directly from the mains, so there’s no need for a separate water tank or cylinder.

Benefits:

  • Compact and efficient – ideal for smaller homes or flats
  • Provides instant hot water on demand
  • No need for a separate water tank

Things to consider:

Not ideal for homes with multiple bathrooms using hot water at the same time.

System Boilers

How they work:

System boilers use a hot water storage cylinder, but most of the components are built into the boiler itself, making them more efficient and easier to install than traditional regular boilers.

Benefits:

  • Suitable for homes with higher hot water demand
  • Provides strong, consistent water pressure
  • Requires a separate hot water cylinder

Things to consider:

  • Requires space for a hot water cylinder.
  • Not as compact as a combi boiler.

Regular Boilers (Conventional or Heat-Only Boilers)

How they work:

Regular boilers use both a cold water storage tank (usually in the loft) and a hot water cylinder. They’re often found in older homes with traditional radiator systems.

Benefits:

  • Best for larger homes with existing traditional systems
  • Works with a separate hot water tank and cold-water storage
  • Ideal for households using multiple taps or showers simultaneously

Things to consider:

  • Takes up more space (loft tank + cylinder).
  • Longer installation process compared to combi and system boilers.

Which Boiler Should You Choose?
