Energy Efficiency

Almost half of the UK's carbon dioxide emissions come from energy we use every day be it at home or when we travel. There are many simple things we can do to save energy which will reduce your bills and help prevent climate change.

  • These range from turning your light when leaving a room, to insulating your cavity walls. Cavity wall insulation is the single greatest energy saving measure you can make. It can cost as little as £500.00 and could save the average household £90.00 per year in heating bills and increase the overall value of your home.
  • Loft insulation, which can be slightly more expensive to install can save you approximately £110.00 per year.
  • Replacing an old boiler with a new condensation boiler can cut your annual energy bill by approximately a third. In addition to the new boiler, simply fitting an insulation jacket to your hot water tank will help keep the water hotter for longer, saving the boiler constantly working to keep the temperature up.
  • If your central heating system is not working efficiently, you are not just risking the costs of boiler breakdown repairs but also subjecting yourself to higher fuel costs than you really need to be. 

What is a condensing boiler?

What are they? 

There are three different types of domestic heating and hot water boiler, combination boilers (known as ‘combi's’), system boilers and open vented boilers. Since April 2005 your new boiler must, by law, be a high efficiency boiler or condensing boiler. This is a boiler that recovers heat that would  otherwise be wasted and uses it to improve the boiler’s heating efficiency.


How do they work? 

High efficiency or condensing boilers (they are the same thing) have a heat exchanger that uses heat in the flue gasses to pre-heat the water. (They are called condensing boilers because most of the heat recovered comes from condensing water vapour in the flue gasses.) The condensed water is drained away and much less energy is required to raise the temperature of the preheated  

circulating water to the desired level.


How energy efficient are they? 

An SEDBUK ‘A’ rated boilers operate with an annual average efficiency of over 90%*. Typically, older types of conventional boilers only achieve efficiencies of 56%*. That means your condensing boiler will use 35% less energy to deliver heating and hot water to your home. This is how a condensing boiler can save as much as 35p in every £1* you spend on energy. This can amount to a saving of over £240* on your annual home heating bill.
