    Water hammer with smart thermostatic valve

    I have gradually fitted smart TRV's to all of the radiators in our house, and in general we are very pleased with them. However, it has become apparent that quite often, when the timing makes the TRV switch off, this sets off water hammer in that radiator. This is easily fixed by running a hot...

    Thermostatic pump overrun temperature?

    A simple question, but so far I've not found a definitive answer:- Some older boilers use a thermostatically controlled pump overrun switch built into the boiler thermostat. They are generally factory set and not adjustable. At what temperature should it switch? I'm specifically referring to...

    Change 4 zone heating system to smart thermostatic radiator valves instead?

    Will a thermostatic shower mixer work with two hot supplies?

    I won't go into the specifics here because it'd be far too long, but in a system I'm building I have two hot supplies - one between 25C and 35C, and one between 45C and 70C. (In short, I have two heat sources that perform differently under different conditions). I want an output temperature of...

    Buzz from thermostatic mixer tap

    Hi, just want to make sure I'm going down the right route with this. I've just installed a thermostatic mixer tap on my bath. When I tried it for the first time it buzzed (a fairly low buzz) After a bit of research I found this could be caused by unequal pressure between HW and CW. I tested the...

    Thermostatic Head Stuck

    Hi, I've got a Drayton Thermostatic Head that is totally stuck on 0, i.e. can't twist it round. I've taken it off the radiator and it still won't twist at all, it's almost like it's locked somehow. Is there an easy way to free it? Thanks in advance.

    Mira Vigour thermostatic shower needs new brushes.

    Hi. Our Mira Vigour thermostatic shower is starting to make a whining noise. It sounds very familiar! Eight years ago I ignored it and ended up having to replace the entire unit. Older and wiser (courtesy of the internet) I realise (now) that it needs new brushes; I've had the cover off and can...
