    Can any combis in the valliant range do a bath and a kitchen tap at the same time or a bath and a shower at the same time. Is this possible?

    Cheers

    You have about 9-15 litres per minute of hot water to play with.

    You can use it however you like.

    But a big shower alone can use over 15 li/min.

    Simply no combi can well supply two outlets at the same time!

    Possible, yes.

    Provided you don't mind waiting an hour for the bath to fill, and the shower to be the most feeble thing since bathrooms were invented.

    Combination boilers are single outlet solutions.
    If you want more than one outlet, some other system is required.

    Also before fitting any combi the mains water dynamic flow rate needs checking too.

    With a blending valve its good.. but not for long...and thats the problem...


    at the end of the day you need a decen store, such as the viessmann 111, gloworm ultrapower of vitodenss 222... they all have decent size stores...

    Is a system store boiler like the gloworm ultra power the way to go in this instance? Two shower and or shower and kitchen taps being used at the same time?

    Personal Opinion here, but the cost difference installing a stored combi to an unvented setup may only be £2-300 with an unvented set probably offering better long term reliability and cheaper maintenance costs.
