and make sure the boiler has an overheat protection kit

you need to buy a suitable conversion kit comprising of a pressure vessel and gauge, plus bear in mind is your system up to the added pressure , as and very old radiators may burst also any old radiator valves may start leaking.then install the pressure vessel somewhere suitable and a filling loop from cold mains into the heating system and cut out the old drop cold feed and expansion pipes and the old header tank .
