I live in Ct and have a tankless hot water system. I have a well and the pressure is set between 45 and 65 PSI. As the water pressure drops the water gets hotter, but when the pump kicks in the pressure jumps up from 45 to 65 and the water gets cool. Is there a way to regulate the pressure coming out of the well tank, and going to to the Tankless Hot Water system so that the pressure stays around 45 PSI? The change in pressure causes about a 15 degree change in temperature. From 110 degrees hot to about 95 degrees cool/warm.

I know this is an old post but this is for anyone else that may have this problem. Install a presure reducing valve on the cold water inlet side of the water heating unit. They come preset at 50 psi and you can adjust it down to 45 psi by turning the adjusting screw on top. They cost about $30 or so at HD or *****. Take the screen out by unscrewwing the bottom nut before installing. If you don't it will clogg up and reduce your flow.
