    Good evening.
    I had a new system fitted a while ago, Vaillant Ecotec 832 combi, hot water is fantastic, plenty of hot water for shower. The heating seem slow at start, burner mode at low level for a while before going up to normal level at 70c. The rad icon is flashing. Is this normal?
    I have a VRT 350f which is rf linked to combi.
    Just want to get it ready for the winter.
    Cheers
    Daniel.

    Yes this is normal. The boilers normaly come set to auto detect the system size and dont always do it so well depending on multiple factors.

    If you look at the manual for the boiler it will tell you how to get to the installer menu and change setting D.00 which is the maximum output to the radiators, if its on auto turn it all the way up or speak to your installer about the issue and they should be able to help or arrange a visit from vaillant to double check its operation.

    Note: the boiler will still fire on low rate every time heating comes on for the first 5 minutes or so before going up to the rate set in D00 on the menu.
