I guess this is the correct forum considering I will be doing the installation. So here goes: I am going to be installing a new water heater and it looks like I will be buying a Rinnai tankless water heater with a pump for recirculating hot water. I will be purchasing from Rinnai a thermostatic valve that is to be installed at the point farthest from the heater. But now my wife throws a wrench into the works. She wants toilets with bidets installed. That's all well and good but our water comes from a well and it is cold. Below 50 degrees F. Great for drinking but not so much for washing those nether regions. Apart from the discomfort cold water just doesn't work as well as warm water. So I am wondering about installing a thermostatic valve at each toilet. Does anybody know if this will work? I just don't know and I think that with all the experience here somebody surely has experience with this problem.
Thanks,
Eric

It's not like taking a whole body shower.

They make small water heaters that would fit behind a toilet. That would be much easier than the proposed idea.

Cold water is better for the pores.

Most Bidets produce electrically heated water. They only connect to the cold water line; just a T off the line that supplies the toilet.

My bidet has a remote control and built in continuous water heater, some have a small tank.

The tank type is more likely to give you a quick squirt of cold water and possibly run out of hot water.

They require a 120VAC outlet near the toilet.

I don’t know how they could not have a tank. Any tankless water heater has some warm up period and a 110v source is pretty limited in how much water it could heat on demand. The whole house tankless heaters ( which I don’t really like) are like 200,000 btus or more.
