    Worcester Bosch Highflow 400 - HW de-pressurises CH

    Agile, good thought but I have become very used to re-pressurising the system lately ! Something has failed inorder for the HW and CH to interact. Heat exchanger is my only thought. Local plumber suggests that Combi boilers have a life expectancy of 10years approx. Is that right ?

    Worcester Bosch Highflow 400 - HW de-pressurises CH

    Good advice - thanks !! I have also thought about replacing the whole boiler for a Highflow 440 or 550 but I will ask Worcester to look at the current on 1st.

    Worcester Bosch Highflow 400 - HW de-pressurises CH

    CH off and HW off. Run the HW tap and the pressure in the CH drops. I have a 2nd problem where the CH is drawing in air to the system. I'm guessing their could be a heat exchanger problem & plan to replace heatexchanged & seals. I'm also suspecting the diverter valve. Any thoughts ...
