Should You Change to a Condensing Boiler?
Condensing boilers have in relatively wide spread use from plumbing retailers for nearly three decades but a surprising number of householders are not aware of their benefits.
Who does not want to cut the cost of their heating bills? Condensing boilers offer a great way of doing this because they are designed to work more efficiently than traditional boilers.
Benefits of Condensing Boilers
Condensing boilers offer two significant benefits to householders:
- Reduced production of carbon dioxide emissions, therefore helping to combat global warming.
- Improving efficiency resulting in reduced energy bills.
How Do They Work?
Condensing boilers work on the principle of recovering as much as possible of the waste heat which is normally rejected to the atmosphere from the flue of a conventional (non-condensing) boiler.
This is accomplished by using an extra large heat exchanger or sometimes two heat exchangers within the boiler which maximises heat transfer from the burner as well as recovering useful heat which would normally be lost with the flue gases.When in condensing mode (for condensing boilers do not condense all the time) the flue gases give up their ‘latent heat’ which is then recovered by the heat exchanger in the boiler.
As a result the temperature of the gases exiting the flue of a condensing boiler are typically 50-60°C compared with 120-180°C in a current non-condensing boiler. At the same time an amount of water or ‘condense’ is produced.
A condensing boiler will have a better operating efficiency than a conventional non-condensing one, due to its larger and more efficient heat exchanger.
