Supermarket boiler upgrade

CH Systems recently assisted in a boiler upgrade for a national supermarket chain.

The works included disconnecting and stripping out three Chaffoteaux Flexiflame 420s that were no longer functional and beyond repair. The team installed three Ideal Evomax boilers in a Cascade; all the pipework was installed in Geberit Mapress low carbon steel, and the flue system was of a “flue dilution” type as this greatly increases options in terms of siting the replacement boilers.

Within the scope of the project, we also replaced a number of seized Crane gate valves, re-sited the Primary Grundfos pump, converted the heating system from open vent to a sealed system; incorporating a new Pressurisation unit and installation of an expansion vessel.
