Common hot water
If you live in a strata block of units and your hot water is supplied from a gas or electric hot water system located in a common area of the building that also supplies other units, this is known as a 'common hot water system'.
If you have a common hot water system, your retailer will calculate your bill by reconciling the amount of cold water supplied to the hot water system, the amount of energy used to heat the water, the number of units drawing from the system and the amount of hot water drawn by each unit, as measured by each unit’s hot water meter.
If some of the units in your strata block are unoccupied for a long period of time, the cost per unit for the common hot water system will be higher than when the block is fully occupied.
Can EWON investigate complaints about common hot water systems?
We can investigate billing disputes about hot water consumption charges where a gas or electricity common hot water system is installed.
We cannot investigate a complaint about:
- the efficiency, age or condition of the hot water system
- the occupancy rate of the dwelling
- action or inaction of a strata corporation, property manager or landlord (eg refusal to engage a licenced plumber to inspect the hot water system).
If your complaint involves strata corporations or tenant/landlord issues, you can contact NSW Fair Trading.
