I think hot water mixing valves are standard for toilet lines in modern construction. It mixes in enough hot water to prevent condensation from occurring on the tank or the bowl. The water wouldn't be shower warm, but judging by other comments here it's less of an issue than one might think.
I guess you might not have this if you live somewhere like west Texas.
In my old rental, the mixing valve malfunctioned and condensation was causing damage to the floor. In my current house, it mixes in too much hot water. If you flush a few times in a row, you can feel the warmth off the toilet bowl. It needs to be replaced, because it doesn't have an adjustment screw.
- Symbiote 7y agoI've never heard of that. It looks like something from North America (any other Europeans heard of it?), and it sounds appropriately wasteful :-) Searching for the condensation problem in Britain, plumbers suggest using an insulated cistern (tank).
- mordechai9000 7y agoI did not know that. Insulation sounds like a good idea. I did find a site specific to the UK (https://www.diydoctor.org.uk/projects/condensationcisterns.htm https://www.diydoctor.org.uk/projects/condensationcisterns.h...) that calls it an anti-sweat valve and says it's available in the US. :) I've never heard of an insulated toilet tank over here. I wouldn't be surprised if they start showing up, though. My current house was built in the 80s, when the region was flush with oil money. I get the impression that building anything energy efficient was seen as a political statement, aside from the added cost to the builder.
- jacobsenscott 7y agoI've never seen a hot water line to a toilet in the US. If people are doing it they only started doing it very recently - maybe for bidet options or something.
