MB1 prevents corrosion on a problem installation.
I have a difficult issue at a Park Home that was piped up in plastic pipe with no oxygen barrier. It suffered corrosion to radiators and after installation of a modern condensing boiler the heat exchanger was blocking. Using system cleaner and then MB1 inhibitor together with an inline filter has kept the system working for 5 years after a local installer recommended £2500 on a new boiler.
