Guide to prevent frozen condensate issues

The Heating and Hotwater Industry Council (HHIC) has released an updated best practice installation and maintenance guide to help avoid frozen condensate issues in the cold months, including steps to thaw frozen pipes.

The HHIC is urging heating engineers to prevent frozen condensate issues during cold snaps. They recommend proper installation and upgrades to avoid freezing and have released a guide for assistance

With cold temperatures predicted across Europe, some households could experience issues related to freezing condensate discharge pipes and become blocked with ice. While it is the responsibility of a heating engineer to confirm that the condensate discharge pipe has been fitted and insulated correctly, prolonged sub-zero temperatures may still raise the need to thaw the pipe. 

Maximum protection in the coldest of seasons

The guide features several key instructions for installing a condensate pipe that will provide maximum protection to the boiler and the customer. It also outlines the alternative of condensate pumps and how to overcome the challenges associated with existing installations. Multiple diagrams to assist with external connections are followed by a list of other considerations, like the type of insulation materials, air breaks in condensate discharge pipes and the issue of unheated building areas.

Steve Sutton, technical manager of the HHIC, said: “This winter, we are determined to make frozen condensate a ‘thing of the past’. By following our guide’s main installation requirements, such as sufficient insulation, this will reduce the likelihood of further callouts to homes with no heating due to a frozen condensate pipe. 

“In recent years, however, the UK has seen temperatures drop to minus 12 centigrade and below in many areas, during periods of extreme cold weather, meaning that even with this guidance, a risk of pipes freezing still remains. We highly recommend that homeowners get a professional to assess the installation of their condensate discharge pipe and make improvements where required.” 

As a result, the HHIC’s guide has included an explanation of what homeowners can do to thaw a frozen pipe and to refer to their manufacturer’s instructions to re-set the boiler.  

Steve continued: “We urge engineers to advise homeowners to take care when thawing frozen condensate pipes owing to the risks associated with the weather conditions. This includes a range of considerations, such as it being essential that boiling water is not used when thawing the pipe.”
