Installing an Energy-Efficient Boiler
Myths About Condensing Boilers
Dispelling myths about condensing boilers is crucial before deciding to install one. Know that condensing boilers remain efficient even without being fully condensing, offering around 92 to 95% efficiency compared to 85% in non-condensing versions. While they were once expensive, costs have dropped thanks to advancements in condensing technology.
Misconceptions surrounding the need for oversized radiators, lower equipment reliability and difficult installation have been debunked. And although some homeowners are bothered by the mist from the flue terminal, this indicates efficient operation. Also, rest assured that slightly acidic condensate is harmless with proper drainage.
Maintaining a condensing boiler is straightforward, and they are now widely available. Transitioning to a condensing boiler is simple, with no need for an existing system overhaul in most cases. Finally, hot water reset is built-in, and variable-flow-primary systems are often less complex than primary-secondary systems found in non-condensing boilers.
Combi Boilers vs. Condensing Boilers
Combi boilers and condensing boilers are often one and the same, as post-2005 UK legislation mandates that all new gas fired boiler installations use condensing technology, including regular boilers, system boilers and combi boilers. Known for their heat recycling ability, condensing boilers capture excess heat from exhaust gases, improving efficiency.
Condensing combi boilers are compact units ideal for smaller homes with modest heating needs, providing instant hot water directly from the mains without needing a cold water tank or external cylinder. Although popular for their efficiency, compactness and ease of installation, combi boilers may not suit larger homes or those with low mains pressure or old pipework. If your boiler is 10 to 15 years old, consider replacing it with a more efficient condensing model. And when selecting a new boiler, choose one with a heating output that meets your household’s heating and hot water demands.
What Is a Condensing Boiler and How Does It Work?
All boilers generate heat with gas or oil, which passes through a primary heat exchanger to boost its temperature before being distributed to radiators. However, only condensing boilers have a secondary heat exchanger to extract additional heat from warm exhaust fumes. This allows modern boilers to achieve over 90% efficiency.
Since 2005, all new gas boilers in the UK have been condensing boilers due to government regulations aimed at combating climate change. Oil boilers followed suit in 2007. Condensing boilers can last 10 years or more with proper servicing. And recognizing whether you have a condensing boiler is easy—simply consider the installation date, look for a plastic flue and check whether a condensate drainpipe is present.
Modern condensing boilers are reliable and safe and come in different sizes to meet various household heating demands. Government-led schemes, such as the Energy Company Obligation (ECO) scheme, are crucial for making condensing boilers accessible to everyone.
