Mixing valve

    Anyone know of any way I can reduce hot water temp in taps. The water is coming out at 60 which is too hot for them. Can't use a mixing valve as I've only mains cold and the hot is a storage heater with its own header tank built in and only 7 feet off the ground. All I can think of is to fit a cold storage tank the same height as the storage heater to have equal head pressures going to the mixing valve. Anyone got another idea.
    Ps there's 8 of these hot water storage vessels in the same room so the owner isn't up for changing them!

    Can you not fit a pressure reducing valve on the mains water?

    Fit a blending valve instead of a thermostatic mixing valve , its the only option you have.

    They are all the same, they dont fail, its the pressure differential that drifts.
    They are a poor mans thermostatic mixing valve.

    Will a thermostatic mixing valve work? I've been reading and it says that hot and cold pressures don't matter but I don't see how it wouldn't matter!

    Throw away the book that says that ! They most defonatly do.
    You can not connect mains water to the cold side of a thermostatic mixing valve , so no one wouldnt work, as you said your cold water is from a mains supply.

    Ye I was thinking that alright. I'm not familiar with a blending valve though!
