| Worcester Greenstar 25HE Combi- Condensing Combination Boiler |
| A condensing boiler is more efficient
due to it's ability to extract more heat from the flue gases normally lost
to the environment through the flue system.
As the flue gases pass through the heat exchanger this extra surface area cools the flue gases to around 55 degrees C whereupon the latent heat within is released and applied to the system. Heat that would normally be lost to the atmosphere. It is this ability to extract as much heat as possible from the gas it burns that gives an exceptionally high level of operating efficiency. This higher efficiency is recognised within section L of the Building Regulations, subsequently achieving a higher SAP or NHER rating. |
