HIGH ELECTRICITY BILLS
With the installation of your new solar hot water system, maximum energy
savings can be achieved with careful planning of hot water usage. Should you
at any time, feel your electricity account is too high, we suggest you check the
following points:
• Is the relief valve running excessively? (Refer to “Temperature Pressure
Relief Valve Running”
on page 18).
• Is one outlet (especially the shower)
using more hot water than you think?
(Refer to
“Not Enough Hot Water” on
page
16).
• Is there a leaking hot water pipe,
dripping hot water tap, etc? Even a
small leak will waste a surprising
quantity of hot water and energy.
Replace faulty tap washers, and have
your plumber rectify any leaking pipe
work.
• Are you using the booster heating unit
properly? (Refer to
“Manual On/Off
Switch”
on page 10, or “One Shot
Control Switch”
on page 11 or “Timer
Control Switch”
on page 12).
• Consider recent changes to your hot water usage pattern and check if there
has been any increase in tariffs since your previous account.
ELECTRICITY TARIFFS
The electricity tariff to which your solar water heater is connected will play an
important role in the overall effectiveness of the system. It is important you are
aware of this tariff to enable you to take full advantage of the boosting period,
i.e. Extended Off-Peak (overnight and day) or extended time controlled,
Domestic / Continuous or Time of Use. For types of tariffs, refer to
“Manual
On/Off Switch”
on page 10.
