New energy efficient condensing boilers not only save money but reduce CO2 From April 2005 it became law that all new and replacement gas fired boiler installations are to be high efficiency condensing type. The intention is to reduce climate change as these boilers produce less CO2, the upside is you can reduce your heating bill by up to 40% as a result.
What is a Condensing Boiler?
Simply put, condensing boilers convert more gas into useable heat, this results in higher efficiencies, reduced running costs and lower CO2 emissions (greenhouse gasses). New condensing boilers can be up to 91% efficient compared to 70-80% efficiency for conventional, non-condensing boilers. This is achieved by a highly effective heat exchanger within the flue which captures wasted heat and re-uses it.
Typically condensing boilers are more expensive due to their greater complexity but are capable of reducing central heating bills by up to 40% thus, re-couping the extra expense.
