Would this shower mixer tap be ok to use with a combi boiler?

    Hi, would really appreciate some advice please. My daughter has just moved to a new house with a Vailant combi boiler and a shower mixer tap on the bath. The mixer is a big old fashioned type tap but is very hard to turn on and off so we need a replacement. We have looked on screwfix web site and found two Bristan models.

    and

    Would these be suitable to use with the combi boiler please. Is it ok just to replace the old tap with this or do we need other things like valves to stop water flowing back or anything. Thank you very much indeed for your help

    it will do, combi boilers are suitable for most of mixers as pressure for cold and hot comes from mains so more less equal

    MDiy.If you want a stand under type of shower,the 2 listed above are not really suitable for a combination gas boiler.

    The Bristan Assure Thermostatic TMV2 Bath Shower Mixer Tap (tap only-chose your own shower kit) is a good deck mixer or as a budget this one https://www.showerdoc.com/inta-vue-thermostatic-bath-shower-mixer-c-w-deck-mounted-legs-vu30020cp

    The hot & cold supplies will need correct orientation,double check valves will be required and some safety and temperature checking on completion :)

    happy plumbing :D

    Thank you for the replies. They have just discovered that the previous owner had already purchased a replacement but had not had time to get it replaced before moving out.

    It is a cheaper one from Argos and they said it is the same one that a neighbour is using. Would this be OK to use with the combi arrangement. Just looking for a quick and cheap replacement to keep them going prior to a full bathroom refit. Thanks

    That will do as a basic shower until you refurbish. But the type Teach suggested above is a better idea.
    The basic type rely on you manually setting the hot and cold taps to attain a suitable temperature ,and there is nothing to keep that temperature stable ,so temp can change when another tap in the premises is used whilst you are showering. A thermostatic valve will react automatically to stabilise the temp in that scenario.

    MDiy,the 3 showers mentioned connected to a gas combination boiler are really just intended for hair rinse or assisted showering. For stand under showering they may work ok in your property but they lack safety & comfort controls.

    This item has a product data sheet which includes some extra information for the installer https://www.idealspec.co.uk/uploads...sandringham21bsm2holewithshowerset_3746_1.pdf

    The 3 mentioned showers come with a single shower handset holder,which is just that. They usually dont aim the shower head in the correct direction for a stand under shower & often the hoses are to short. The advert images will show the shower head holder at a very low height.

    Asthe bathroom is going to be renovated,fitting the inta-vue shower to the bath now has the advantage it can be reused as a wall mounted mixer (discard the bath deck legs) in the future or keep it as a deck bath shower mixer. options.

    Anyway you have options ;)
