Head of Marketing Chris Harvey said:

 “There is a clear need for larger size radiators to cope with the lower circulating system temperatures generated by renewable heating systems and we are making sure our installer and specifier customers have access to the full range of options they will need in the months ahead.

“The arrival of the new upgrade to Building Regulations with effect from 15th June in England and from November this year in Wales brings with it a realisation that the key figure to bear in mind is 55°C – the maximum flow temperature for all new wet heating systems from this date. The regulations also say that heating appliances and radiators should not be oversized. TRVs need to be fitted to every radiator except where there is a room thermostat fitted. The differential between the flow and return should be 10°C – giving a 45°C return, and a mean water temperature of 50°C. This will have an impact on radiators but simply means that sizing of radiators is more important than ever and all the advice you could need is available through relevant websites to point installers and specifiers in the right direction with regard to using the right radiators in the right applications. 

“The transition from fossil fuelled, boiler driven systems to heat pump driven renewable systems is well underway and we’re making sure that installers and specifiers realise fully that radiators are ‘fit for the future’ and more than capable of providing the necessary heat around the home – radiators need to be sized properly as always to provide sufficient heating capacity and insulation needs to be evaluated to ensure it is adequate to ensure the heat in the home does not escape into the atmosphere.”
