Switch to energy efficient electric heating and hot water

Heating your home and water with electricity is regarded as highly efficient because more of the energy (units) used by an electric boiler or heater is converted into the heat you need. Nothing is wasted up a chimney or flue.

The increased efficiency of electric heating coupled with our range of tariffs make electric heating highly economical too.

Energy consumption is measured in kilowatt hours (kWh). One kWh equals one unit. The price of units depends when in the day they are used and which tariff you are on.

An electric heater is regarded as 100% efficient because its energy input - the electricity you are billed for - matches its heat output and nothing is lost in-between.

Electrically powered ground or air source heat pumps are regarded as 200-400% efficient because their heat output can be two to four times the amount of energy used to power the pump. You buy 1 kWh (unit) of energy and get 2-4 kWh of heat.

The difference is known as 'useful kilowatt hours' and this efficiency rating is important when comparing running costs of heating systems.

An old gas or oil boiler could be only 65% efficient, meaning you are only getting 65p of heat for every £1 you spend. The rest of your money goes out of the flue or up the chimney.

Heating your water by electric immersion heater in the summer months, when you don't need your central heating boiler running, is also economical on our Economy 7 Tariff. The energy needed to heat your water is delivered directly into the tank and none is lost out the flue or up the chimney

Advantages of electric boilers:

  • Easy replacement for gas or oil boilers
  • No flue or storage tank required
  • Easy to install and competitively priced
  • Economical to run
  • Clean, convenient and highly efficient
  • Low CO² fuel reduces your carbon footprint
  • Space saving and even heat distribution (with underfloor option)
  • Can be integrated with renewable technologies
