Combi Boiler?

  Combi Boiler?

 A boiler is basically a water heater, which can provide heating and hot water to your home. They burn gas or to heat your water, and are the conventional method of providing residential and commercial premises with heating and hot water in the UK. Combi boilers are one of three main types of boiler widely used by homes and businesses.


Combination boilers,or ‘combi boilers’, no matter which combi boiler you choose, it will always deliver hot water on demand, by taking cold water from the mains and heating it as needed. This way, hot water is available ‘on tap’, 24 hours a day.

What is a combi boiler good for?

Combi boilersare ideal water heater systems for small houses or flats. They are economical to run and don’t take up much space, as they don’t require an external hot water tank. They are also one of the most straightforward boilers for a Gas Safe engineer to install.

What is a combi boiler not so good for?

You won’t be able to use hot water from many sources at the same time, and this choice is not ideal if your property has low water pressure.

Other types of boiler includesystem-condensing boilers, which are better suited as water heater systems for larger homes with a need for more hot water. They have a sealed hot water storage cylinder, which can be installed, in a space such as an airing cupboard, loft orgarage.Heat only boilers, or ‘open vent condensing boilers’, require two tanks in the loft and a hot water tank in an airing cupboard or loft . These are best for those who need to replace a heat only boiler cheaply, and people who want to be able to run hot water from more than one tap simultaneously.

Older boilers

If your home has a very old central heating system then you may be wise to invest in a newer model, as this could save you up to 35% on your average yearly heating bill.

Small homes benefit from combi boilers for the reasons mentioned above, so it’s no surprise that they are the best-selling boiler types for gas central heating, accounting for around 69% of new boiler purchases. However, if this is your choice then you will also need to decide which combi boiler to install.
