Re: Thermostatic shower mixers 17Apr 04, 2009 8:14 pm ok, if you are one of the chosen ones, you get the shower temp right just like that. The rest of us turn hot water on, wait a while then play around until the water feels right to take a shower, some just turn hot water on, undress and then start adjusting the temperature. That's all down the drain. You could set a TMV to a certain temperature to avoid this, then its hidden in the wall. What if you want it colder? Or hotter? Then you would wish for something else, like an thermostat you could adjust, maybe.

No, one doesn't have to be Jewish to get even water temperatures. It sounds to me that your problem is simply unequal water pressures. If you have a storage unit over 125 liters you should have a pressure reduction valve on it. This will drop your hot water pressure down to less than 600kpa. Your cold water pressure will be in most cases substantially more than this. The hot and cold will constantly fight each other with the cold winning, making the adjustment of temp difficult. If you have a relativly modern shower rose on your shower yoll have a water saving restrictor on it. This will compound the problem. The way to remedy this is to install a pressure limiting valve equal to that on the hot on the outlet of your meter and remove the restrictor. For best results, the one on your hot water unit should be removed. Quote: The rest of us turn hot water on, wait a while then play around until the water feels right to take a shower, some just turn hot water on, undress and then start adjusting the temperature. Long waits at the shower are caused by long pipe runs from your hot water unit. A TMV wont change that. The only way to have instant hot water at a point a long way from the shower is to install a circulation pump with a return line to the Hwater unit. You should be aware that TMVs go easily out of calbration and can require expensive maintenance and parts aren't cheap. TMVs are a safety device, not a water saving device. Re: Thermostatic shower mixers 19Apr 05, 2009 4:22 pm guess you got me all wrong. This thing is not a TMV and I don't want a TMV to preset my shower temperature and I suppose if the temperature alternates by a few degrees I would not even feel it. Just go, have a shower, turn on hot full blast, then once hot is there, fiddle around with cold until it feels right, then fiddle again with hot and cold until the flow feels right. Now imagine you would just have to adjust the flow for once and in some stage (once the hot water made its way trough 30m uninsulated pipe) it would come out just right.

What you want can be acheived with an ordinary in wall flickmixer, as long as there is no conflict in water pressures and theres no restrictor in the shower rose. I'll look into different shower heads and ask the plumber about some engineering and see what he says.
