HIGHER THAN EXPECTED GAS 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 energy bill is higher than expected, we suggest
you check the following points:

Is the relief valve running excessively?
"Temperature Pressure Relief Valve Running"
Refer to

Is one outlet (especially the shower) using more hot water than you
think?
"Not Enough Hot Water"
Refer to

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 a plumber rectify any
leaking pipe work.

Is the in-series water heater operating too frequently?
"In-Series Water Heater Operating Too Frequently"
Refer to

Has there been an increase in hot water usage?
An increase in hot water usage may result in an increase in booster operation.

Has your water heating tariff rate been increased by your energy retailer since your previous bill?
