The government has banned all non-condensing boilers and has advised replacing them with new condensing boilers. 

Check Your Eligibility In 60 seconds

All new boilers installed in UK households must now be condensing units with high efficiency ratings. The Eco4 Grant is a government initiative designed to help homeowners and landlords improve the energy efficiency of their properties. These criteria were updated, requiring all new boilers in the UK to have a minimum energy efficiency rating of 92 percent. 

A boiler’s average lifespan is 10 to 15 years. So, if your boiler was installed before 2005, you probably still have a non-condensing boiler.

Differences in Installation

Since the exhaust gas from non-condensing boilers is so hot. They need to be vented through a suitable chimney or flue. Condensing boilers may be vented using a larger choice of materials. Such as PVC and polypropylene, and have cooler exhaust gas since the heat is recycled. Because condensing boilers need a drain pipe for their acidic condensate liquid, installation locations may be restricted. A drain is not necessary for non-condensing boilers as the exhaust gas does not condense within the appliance. The size of the house and boiler, the number of zones, and the amount of gas piping and venting that has to be done may all affect the installation process, regardless of the type of residential gas boiler you select.

Maintenance and Durability

Boilers, whether condensing or non-condensing, can last for 15 to 20 years. The installation quality of the boiler, the local environment. The way you use it, and how well you maintain it all affect how long your heating boiler lasts.

Our Free Boiler Scheme professional should examine and service all home boilers. The heat exchanger on both condensing and non-condensing boilers has to be cleansed once a year, or more frequently depending on combustion efficiency.
