Boiler Types

Choosing the right boiler is important for your home

The most widely used boiler types in the UK are combi boilers, system boilers and conventional boilers. Each boiler type differs in the method of providing heating and hot water, and each type has its own advantages.


Combi boilers are the UK’s most popular choice as they allow households the luxury of a small energy efficient system without the need for cylinders or tanks that use valuable storage space.

We would recommend a combi conversion if you live in a property that is 2 bathrooms or less and currently has an old ‘conventional’ system.

However, if you have a busy household with 3+ bathrooms and need large quantities of hot water, we would suggest replacing your boiler with a more efficient but similar heat only option.

Combi boilers

A combi boiler heats water instantly when you turn on a hot tap. It does not need a cold water expansion tank or a hot water cylinder, which can free up precious storage space.
The water it heats comes straight from the mains, so the flow rate at the tap is usually very good. A new combi boiler can be 90% efficient so replacing an old ‘conventional’ boiler can provide substantial savings.
Combi boilers are suitable for small to medium sized homes with between 1-3 bathrooms all requiring hot water from your boiler.

Benefits

  • Highly Energy Efficient And Cost Effective
  • Compact Size
  • No Need For Space-Consuming Water Tanks And Cylinders
  • No Risk Of Loft Pipework Freezing
  • Unlimited Hot Water On Demand

System boilers

System boilers are suitable for larger, family households with a greater need for heating and hot water. We would typically fit system boilers in homes with 3-5 bathrooms.
System boilers require a cylinder for storing hot water, however the main heating components necessary for this are housed within the boiler itself, which allows for a quick and easy installation.

Benefits

  • Highly Economical When Used In Accordance With Your Household Needs
  • Reliable Water Pressure To All Taps And Showers
  • No Cold Water Tank Required
  • Built-In Components Making Installation Quicker
  • Compatible With Solar Water Heating Systems

Conventional boilers

Conventional boilers are often found in older homes that haven’t updated their system. They use an expansion tank in the loft to store cold water and a hot water storage cylinder & pump to move hot water around the system.
If you are updating your system and live in a 1 or 2 bathroom house, you should consider the benefits of converting to a combination boiler. However, if you live in a larger house with 3 or more bathrooms, we would suggest staying with a heat only option.

Benefits

  • Hot Water Can Be Sent To Multiple Points At The Saame Time
  • Good Option For Low Water Pressure Areas
  • Quiet, Unobtrusive Noise Output
  • An Added Electrical Immersion Heater Will Provide A Backup In An Emergency
  • ‘Like-For-Like’ Swaps Are Relatively Straightforward
