How hot should the water be?

Your hot water service has an adjustable thermostat suited to your hot water model. You may select the temperature suitable to you. Remember that if you operate the heater at low temperatures you may run out of hot water. On the other hand high water temperatures use more gas.

Not enough hot water?
Is the  Temperature and Pressure Relief valve running at the side of the unit?
Do you have the correct size heater for your requirements?
Is one outlet {especially the shower} using more hot water than you think?
A careful review of the family’s hot water usage and if necessary check the shower flow rates with a bucket and watch. If it is not possible to adjust water usage pattern an inexpensive flow control valve can    be fitted to the shower outlet.

High gas bills.
Is the Temperature and Pressure Relief valve running excessively.
This valve is at the top of the heater and is essential for efficient operation. Normally it releases a little water through the drain pipe during reheating period after hot water is used.
Is the hot water too hot? Set the temperature dial to midway between HOT and WARM if the control knob is white or to 3 if the control knob is black.
Is there a leaking hot water pipe, dripping hot water tap? Even a small leak will waste a surprising quantity of hot water and gas.
Temperature and Pressure Relief valve running.
It is normal and desirable that this valve allows a small quantity of water to escape during the heating cycle. However, if it discharges more than a bucket of water in 24 hours, there may be another problem.

Heater appears to be leaking.
When the heater is first lit up condensation may form within the burner area. Condensation can also be formed when the heater is filled with cold water after heavy usage of hot water. This is quite normal, especially in winter months, and will dry off as the water is heated.

For High Efficiency models.
The plastic drain near the bottom left hand side of your heater will often lose a dribble of condensate. This condensate flow is caused by the normal, very efficient operation of the heater and does not come from your tap water.
