What it concludes

• A thermostatic mixing valve allows a 50-gallon water heater to produce up to 40 percent more usable shower water.
• Running a water heater at 140 degrees increases hot water output significantly, but requires a mixing valve to prevent scalding.
• Water at 140 degrees causes third-degree burns in just 5 seconds.
• Choosing the right mixing valve requires checking for three things: fitting size, ASSE 1017 rating, and integral check valves.
• Increasing water heater temperature from 120 to 140 degrees increases energy costs by about 20 to 30 dollars a year.
