Description: This old storage combi boiler was old and not working properly. We also found that it had been piped up wrong internally! We modified the pipe work before hooking up the new system and while I worked on the Worcester 440 High Flow boiler my colleague changed all of the valves throughout the large house. We had everything completed in one day and the new boiler is producing heat and hot water more economically than the old one.
