I have recently purchased a home with a Thermostatic shower and when at the coldest setting the water was hot. I did some researched and changed the temperature cartridge and now the water is warm. if I turn off the hot-water then I get 100% cold water (so I know the water is flowing and it connected to the right place).

My question - when I turn to coldest setting I was expecting 100% cold water (like on every other shower I ever had), but the guy at the store is telling me that with a thermostatic shower you cannot have a "cold shower", only warm ...

Does this make any sense? Thanks,

  • Any chance that the cold and hot inputs have been reversed? – BMitch Dec 30 '14 at 20:45

    Ours runs warm until the combi-boiler gets going, then cold when the hot is hot enough to effect the thermostat in the shower. What happens if you run it hot then turn it down? – Pete Kirkham Dec 30 '14 at 21:44
  • @BMitch Nope (hot left, cold right), and I can open/close the valves and they react correctly – Jonathan Dec 30 '14 at 22:19
  • @PeteKirkham mine goes from warm to hot - I am looking for 100% cold (no hot water - freezing cold shower). Is that even possible with this unit? – Jonathan Dec 30 '14 at 22:20

    Do you know the make/model? – Steven Dec 31 '14 at 4:16
