Thermostatic(?) valve problem
I have Horus fixtures in my shower stall. The shower diverter is labelled up to a maximum temperature of 50C (ie 122F). However, even set at the maximum temperature, the shower never feels hot enough to me (no matter how long I run it). FWIW, before we changed the fixtures in this bathroom, the water was very very hot (and the water pressure was also much better.)
Today I took a candy thermometer and measured the temperature of the water, with the diverter set at the maximum, ie 122F. I put the candy thermometer in a prewarmed container and held the nozzle right over it so that the aeration would not cool down the water.
The reading I got was 100F, not anywhere near 122F. Eight feet away, I tested the hot water temperature in my bathtub tap and my sink tap. Both reached a maximum temperature of 55C or about 131F.
I also checked my husband's bathroom, on the other side of the bedroom, which has a diverter from a different mfr labelled up to 125F. I was able to get water that tested at 120F from his shower.
What can I conclude from this experiment? I am tempted to say the diverter in my shower is defective. Is that a reasonable assumption? Can I conclude it is the product, or could installation have impacted this result? This is a very expensive fixture ... WWYD
Thanks in advance.
