“This is the exact replacement for my boiler tankless coil. It has a wider range temperature 70F-145F setting. my old one lasted only about 5yrs due to hard water and scale buildup internally. only drawback is the adjusting dial without number scale. Other than that it's a high quality valve.”
“Love the check valves to stop Thermosiphoning. Didn't even know the valves were included. Nice. The temperature gauge stops me from running upstairs to check the water temperature. I still did but this eliminated many trips.”
