Standard steel panel products, which are installed in toilets or any
areas of high humidity (including bathrooms, kitchens and shower
rooms, etc.) are limited to a twelve month parts and labour warranty.
APPLICATIONS
Stelrad radiators are suitable for two pipe installations. For single pipe
applications, it is advisable to use diversion tees in the pipework, as
this will assist in obtaining design performance from the radiators.
Although our radiators are suitable for Microbore pipework, the back

radiator goes through a final curing stage. It is then allowed to cool,
prior to packaging.
