This is normal, but if the pump
is running more than once an
hour, additional insulation on the

Why is the water not hot enough?
Booster is not configured correctly
Electric booster should have the
thermostat temperature set to at
least 60°C. Booster must be left
on off-peak, or controlled by timer.
Household hot water usage too
high
Unit may be incorrectly sized,
contact your plumber. Remember
an efficient shower head uses 9
litres/minute. (10 minute shower =
90ltrs water)
Tempering valve installed
A tempering valve must be
installed on every solar hot water
system. Tempering valves will mix
water down to 50°C
Tempering valve may need
replacing or servicing.
