Gas Boilers

Boilers

All Vokèra boilers are condensing, or high efficiency, boilers as it is also known which maximise the heat the boiler generates by recovering some of the lost energy, which would normally be lost through the flue.

A condensing boiler can on average save you 30% of your energy usage. Legislation that came into force in 2005 now requires that any new domestic gas appliance is a condensing boiler.

In 2015, a piece of mandatory legislation was introduced that requires the presence of energy labels on heating products and systems.

There are three main types of condensing boilers:

Combi Boilers

A combi boiler, also known as a combination boiler provides heat for central heating and domestic hot water upon demand. With a combi boiler heating system you do not require feed and expansion tanks in your loft space or a storage cylinder, therefore saving space. Read more here >>

System Boilers

A system boiler is a boiler that is installed on a sealed central heating system, as the word suggests it is not open to atmospheric pressure. In this type of heating system, a system boiler connects to a storage cylinder that provides the domestic hot water and central heating. Read more here >>

Open Vent Boilers

An open vent boiler is a boiler that is installed on an open vent central heating system, the term open vent, relates to the heating system being open to atmospheric pressure, as major components to an open vent system includes feed and expansion tanks in the loft space. Read more here >>

Combi Boiler

Combi Boilers

A combi boiler, also known as a combination boiler, provides heat for central heating and domestic hot water upon demand. With a combi boiler heating system you do not require feed and expansion tanks in your loft space or a hot water storage cylinder, therefore saving space.

Domestic hot water is fed from the mains supply which maintains high water pressure and is heated instantly. However if you live in a low water pressure area, or have multiple bathrooms, a combi boiler may not be suitable. We always advise that you seek advice from your Gas Safe Registered engineer.

  •  Utilise your loft space/airing cupboard for another purpose and want to remove the tanks and hot water storage cylinder
  •  Have instant hot water on demand
  •  Save space
