    We are in a lodge at CP in Cumbria.

    the boiler is a Worcester Bosch combi

    the heating is only getting up to a medium temp and the hot water is Luke warm.

    I have just checked the boiler and it has no pressure in it but it is still working.

    the engineer is coming later

    anyone know if these boilers reduce output if pressure is low?

    I just hope the temp increases after he’s been.

    the temp dials were both near maximum. 8.5/10 zone if using that type measurement

    Do Worcester Bosch combis reduce heat output when pressure is zero

    our boiler at centre parcs is running the heating and hot water Luke warm

    the temp dials are nearly at max but the output is not that good

    any ideas?

    an engineer is coming this morning

    If system pressure is zero I'm surprised its working at all. Other issue this time of year, if the incoming cold water is colder than usual, then the boiler may struggle to heat it adequately. Try turning the tap right down to slow the flow and see if it improves. If heating is also cold though, that may be another issue. It needs to be looked at to confirm.

    Ok thanks

    not sure why the post is x 3

    any way the engineer came this AM and the pressure took about 40 seconds to fill up. Normally you just need 10 seconds but this system was pretty empty.

    so these boilers still work on zero pressure.

    the hot kitchen tap seemed much better.

    tonight at bath time will be the test
