The are 3 types of Boilers

  • Combi
  • System
  • Regular

Combi Boilers

A combination or ‘combi’ boiler is both a high efficiency water heater and a central heating boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won’t need a hot water storage cylinder or a cold water storage tank in the roof space.

They are also very cost-effective and energy-efficient as water is heated instantly rather than being heated and then stored in a cylinder. An added benefit is that hot water is delivered at mains pressure, which means that you could get a powerful shower without the need for a separate pump.

  • Compact sizes make combi boilers perfect for smaller properties
  • Ideal where there is little or no loft space
  • No need for a hot water cylinder allows increased living space
  • No cold water storage tank frees up a loft for conversion
  • No risk of loft pipework freezing
  • Less pipework in the home makes installation typically cheaper

Worcester Greenstar CDi Classic Combi Gas Boiler

Top-of-the-range combi boiler with a market leading output of up to 42kW. Suitable for all homes with one or two bathrooms it has hot water flow rates of 17.2 litres/min and is renowned for its ease of installation, advanced features and future-proof technology. Advanced features include the ability to range-rate the CH output to perfectly match the home's requirement.

 

System Boilers

System boilers require a cylinder for storing hot water, however the major heating and hot water system components are built into the boiler itself, making it quicker and easier to install. In addition, there is no need for a tank in the loft, so it can be an option in a home with little or no loft space or where the space is earmarked for a conversion.

These boilers are also compatible with solar water heating systems, which deliver environmental benefits as well as lower energy bills.

  • Ideal for homes with more than one bathroom
  • Constant supply of hot water to any number of taps at the same time
  • No need for a loft tank, freeing up space and eliminating worries about leaks or frost damage
  • Economical to run
  • Built-in components makes installation quicker and neater

Regular Boilers

Regular boilers (sometimes known as traditional, conventional or heat only boilers) are ideally suited to homes that already have a traditional heating and hot water system which is linked to a separate hot water cylinder. These boilers also need a cold water storage tank in the loft to feed the hot water cylinder as well as a tank that maintains the water level of the central heating system.

A regular boiler may be the best option for replacing an existing boiler if the property has an older radiator system, as it might not be able to cope with the higher water pressure that is delivered by system or combi boilers.

  • Perfect for homes where a lot of hot water is used at the same time
  • Ideal where there are two or more bathrooms
  • A good option in areas where water pressure is low
  • Compatible with solar water heating systems for a lower carbon footprint and lower energy costs
