Why is the water from my HTP EVG080C2X045H Water Heater too hot or not hot enough?

If the water from your HTP Water Heater is either too hot or not hot enough, the mixing valve setting might be too high or too low. Refer to the mixing valve manufacturer's instructions for setting the mixed temperature. Alternatively, the mixing valve could be out of calibration and needs replacement. The thermostat setting might also be too high or low, so change the setting as required. Other possible causes include a thermostat out of calibration (replace the thermostat), missing thermostat access panel(s) and/or insulation (inspect and replace as needed), a thermostat not resting tightly against the mounting plate (ensure that retaining spring(s) or mounting screws hold the thermostat tightly to mounting plates), or utility control limiting energy usage.
