HIGHER THAN EXPECTED ELECTRICITY BILLS
With the installation of your new air sourced heat pump water heater, electrical energy savings can be
achieved. Should you at any time, feel your electricity bill is higher than expected, we suggest you check the
following points:
•
Is the water heater operating for extended periods with the electric heating unit?
Prolonged periods of use where the ambient air temperature is outside of the heat pump’s operating range
when heating is required will increase the amount of heating required by the electric heating unit to ensure
a supply of hot water, increasing running costs.
•
Is the relief valve running excessively?
Refer to
“Temperature Pressure Relief Valve or Expansion Control Valve
on page 34.
•
Is one outlet (especially the shower) using more hot water than you think?
on page 33.
•
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.
•
Has there been an increase in hot water usage?
An increase in hot water usage will result in an increase in heat pump operation.
•
Has your water heating tariff rate been increased by your electricity retailer since your previous bill?
•
Is the heat pump water heater on the same tariff as the water heater replaced?
The impact on an electricity account will depend upon the tariff arrangement of the water heater replaced
and where you live. Contact your energy provider for more information on tariff arrangements and cost
comparisons.
