Met Office data suggesting an impending drop in temperature had led industry body to play up best practice to prevent possible boiler failure due to frozen external piping
The Heating and Hotwater Industry Council (HHIC) has said it is aware of a “significant proportion” of boiler installations not fitted in line with updated standards or manufacturer instructions. These standards are intended to ensure appliances are protected against adverse cold weather.
Updated guidance produced by the HHIC has now been re-issued to ensure external condensate discharge pipes are installed effectively to prevent freezing amidst Met Office warnings of an increased likelihood of cold weather that could lead to snow and frost across the UK.
A brief period of intense cold weather across the UK during 2018 - nicknamed the ‘Beast from the East’ - saw a significant number of boilers from a range of manufacturers failing as a result of frozen external condensate pipes.
HHIC said it was now responding to concerns about the impact of cold weather by reissuing key information for both end users and engineers that details remedial action available to protect external condensate pipes.
Stewart Clements, director of the organisation, said the guidance was designed to ensure pipework that could not be connected to an internal point can still function correctly if temperatures fall drastically.
He said, “HHIC have updated current industry guidance which assists engineers with both installation and assessment of current condensate discharge pipes, which they can and should review during any visit to the appliance such as a service, repair or replacing a heating system.”
“In addition to this guidance all other technical requirements for condensate discharge installation given in the first instance the appliance manufacturers’ installation instructions or if referred to by the appliance manufacturers; British Standard BS 6798:2014, should still be followed.”
Mr Clements said he would urge engineers to familiarise themselves with the organisation’s guidance documents in response to the Met Office warnings.
HHIC added that it was vital that manufacturer instructions took precedence when performing work to ensure an appliance functioned correctly and retained a valid warranty.
