Hi, Hoping for some advice. I'd like to install the 'finrad' type of radiator in a particular place in my house, and they seem to vary hugely in price. Aluminium ones like this seem to be quite cheap - ALDE FINRAD CONVECTOR ALUMINIUM 400MM - Midland Chandlers - Canal and Narrow Boat Equipment I know they're sold for narrowboats and the like, but is there any reason why I couldn't hook one of those up in place of a normal domestic radiator? Is there any problem with using aluminium pipes? I currently use the Corgi corrosion inhibitor that Toolstation sell. And mine is a pressurised system running off a combi boiler. Thanks in advance!
