Setting the water temperature

The desired temperature of the hot water can be adjusted on the front control panel of the heater.

The GWH 2400 ES has an electronically controlled gas valve that modulates the burner input in response to both varying hot water flow rates and/or changes in any incoming and outgoing water temperatures.

Note: The water heater, running at minimum BTU, may still achieve temperatures above the desired set temperature. Low flowing fixtures are the leading cause of this type of temperature overshoot. To combat this symptom, clean fixtures or replace with higher flowing ones.

Saving water resources:

BMake sure you close all the taps after any use. Avoid leaving the taps dripping. Repair any leaking tap.

BDefine the temperature you want, in the appliance or with the remote control. This way you have the precise water flow needed (mixing cold water to regulate temperature will increase the water flow with consequent waste of water).
