Why We Chose Electric Combi Boilers

Why We Chose An Electric Combi Boiler Heating System

We chose to fit an electric combination boiler system to the Flower Barns At Yew Tree because:

  • The system is the most environmentally friendly system available
  • It can use completely green electricity and emits no carbon dioxide
  • It requires no tanks, flues or external vents
  • Running costs are competitive

It is great to know that the barns are ahead of the government’s requirements to phase out the use of gas. The government currently have announced that no new gas boilers will be allowed in new properties by 2025. So using electric combi boilers is quite simply “doing the right thing”.

What Is An Electric Combi Boiler System?

An electric combi boiler system uses electricity to heat water, which is then available for washing and also for heating the home. Water is fed into a tank within the boiler unit where it is heated and then supplied to pipes that run under the floor downstairs and upstairs to radiators. This gives you water based underfloor heating, downstairs which is intrinsically thermally efficient. The system is pressurised and so gives good flows of water, allowing excellent showers to operate.

The whole systems has an array of controls to control, the temperatures, operating conditions and time of operation.

Costs of Running

The cost of running depends heavily on the usage of the system.
There are multiple tariffs available which can be used in conjunction with the system including:

      • Standard Tariff
      • Economy seven
      • Economy 10
      • Electric Car Owners Tariff


Significant savings can be made by choosing the tariff to fit your lifestyle.
We will be happy to work with you to choose the best tariff.

For a rough comparison we found these figures on the web:

  • Small flat – gas heating £450 per year – electric boiler £470 a year
  • Detached house – gas heating £1150 per year – electric boiler £1000 a year
