    Screeching Grundfos ERP 2015 pump in Vaillant Ecotec Pro 24

    Drain the boiler, undo the 4 allen bolts and pull the pump, check the vanes for debris.

    HEAT EXCHANGER IS STEEL MUCH BETTER boiler advice needed

    Heating problems. Timer says everything is on but radiators not!

    Have you hot a 3 port valve in the airing cupboard? If so it sounds like the motor has failed.

    HEAT EXCHANGER IS STEEL MUCH BETTER boiler advice needed

    I've counted the moving parts in my vaillant and count 4. Pump,fan,gas valve and pressure guage.

    Booster pump installed successfully, but now boiler goes to overheat!

    When you loosened the red gate valve you essentially drained most of the water from the boiler circuit, go to your boiler and check the pressure guage, what does it show? If it's showing empty then use the filling loop to top it up to 1.0 - 1.5 bar. Then try again.
