I've read here and on other diy boards and sites that after changing a central heating system there will be a need to balance the system to ensure an even amount of heat to all radiators.
I have also read that the easiest way to do this is using radiator thermometers but I have tried a search and can't find them anywhere. Does anybody have any links to places I can either buy or hire them from.
A first for me.......... an item that doesn't exist on the internet.
