Instant Hot water at faucets?

Is there actually a question you’re trying to get answered?

There are several ways to get “instant” hot water.
- local small water heater – obviously, heats water at the tap or very near it (various products can do this)
- recirculating valve — recirculates water between cold and hot water pipes

TOO faucets yes, Insta Hot brand is one. Don’t know what kind house store sell i.e. home depot

Check with your local Lowes, Home Depot or plumbing supply store for what is called a point of use water heater They can be easily installed under the sink and can be plugged into a standard outlet. These will save you money if you have an electric water heater for the whole house because it doesn’t use as much energy to heat up. However because of the size of these heaters it may not keep up with high demands. The tank inside is only a few gallons.

they make a little pump that taps into your hot water line, when it drops below 85 degrees, it turns on and pumps the cool water into the cold water line. this tends to make your cold line extra warm when you first turn it on. no water is wasted because the water ecentialy flows back through the cold line and back into the tank. dont install it yourself unless you are good at plumbing stuff. it doesnt need to be on the tub either, you can put it under the sink instead. the hot water isnt right there imediatly, but it is a lot closser
