There are now two main types of modern boilers using gas, LPG (Liquefied Petroleum Gas) or oil:
- Condensing boiler: A condensing boiler typically converts 88% of fuel into heat. In a conventional boiler much of the heat produced is either lost to the surrounding air or disappears up the flue. Condensing boilers extract the heat from the products of combustion using a second heat exchanger
- Condensing Combi boiler: High Efficiency boiler that will heat your home and provide instantaneous hot water, without needing a hot water tank
When you plan to install a new boiler or replace an existing one, you will now (in almost all circumstances) need to install a condensing boiler to meet the higher standards for energy efficiency required under Building Regulations.
If your boiler is 15 years old or more, replacing it with a new condensing boiler, with appropriate heat output for your property size, will save you around a third on your heating bills.
Further information about grants and discounts to help with the installation of boilers is available here.
