Collectors shaded
Ensure the glass on your solar collectors is free of dust, salt spray or any other matter, which may reduce the
effectiveness of the solar collectors. Hose or wash the collector glass with water and a soft brush when the
solar collectors are cool. Trim any trees which may shade the solar collectors.
If trees or other objects shade the solar collectors or if the glass is dirty, the effectiveness of
the solar collectors will be greatly reduced. Clean the collector glass (Clean the panels with
water and a soft brush), trim trees or relocate the solar collectors if the obstruction is
permanent.
Are you using more hot water than you think?
Is one outlet (especially the shower) using more hot water than you think? Carefully review
the family‟s hot water usage. It is a good idea to restrict the amount of hot water used by
simply fitting an inexpensive water saver shower rose. Conventional shower roses can require
up to 20L/min of flow to spray properly, but a large amount of this water is wasted. We
recommend showers roses that pass 8-9L/min of shower flow.
Thermostat setting
Ensure the thermostat setting is appropriate. You may choose to have your electrician adjust
the thermostat upwards to gain additional hot water capacity when boosting.
Tempering Valve Malfunctions
Have your plumber check to make sure your tempering valve is calibrated and is functioning
correctly – this can cause the water from your taps to be cool, even though there is plenty of
heat available in the water heater.
WATER FLOWING FROM THE OVERFLOW OUTLET
Normal Operation
It is normal that the PTR pipe will leak water when the unit is in operation. This is caused by
the expansion of the tank water, and should stop after the heater has reached maximum
