In the little fighters for pc meantime turn off the supply and return valves to the unit, and open up the bypass valve to allow water through without going through the softener.
Please read our, legal Disclaimer, plate heat exchangers in combi boilers are secondary heat exchangers.In a dirty system the narrow waterways of the plate heat exchanger act like a filter, trapping the black iron oxide sludge and other debris.If you want to link directly to this page, the hyperlink.In central heating mode, combination boilers heat water in the main heat exchanger and pump it round the heating circuit, through the radiators or the under-floor heating pipework to heat the house.Filters, cyclone type separators and magnetic sludge removers such as MagnaClean and Spirovent Magnabooster and Spirotrap MB3 help to clean the system but should not be used in place of proper power flushing if the system is dirty.(You should also check that any isolating valves in the mains water line are fully open and that any filters are clean).Lime scale is not much of a problem in the heating waterway of the plate heat exchanger.
As it passes through the plate heat exchanger it picks up heat from the metal plates in contact with the hot heating water in the other channel; the mains water goes in cold and comes out hot, passing to the taps.
And the pressure has dropped.2 and i have read the installation booklet, but it doesn't help.
The photo on the right shows a typical plate heat exchanger.
A completely different problem with plate heat exchangers (and other secondary heat exchangers) is leakage between the two waterways within the heat exchanger.

In hot water mode the diverter valve in the boiler diverts the heating water from the radiator pipework, sending rtlwintersports2008 no cd crack it instead through the plate heat exchanger.
