Supplementary heat sources
If a supplementary heat source is connected to the storage tank, the maximum energy input
cannot be more than 10 kW, including the electrical element. Where greater input is
required, a pressure and temperature relief valve with a higher kW rating is to be fitted to the
storage tank.
Where stove coils are used for supplementary heating the water must be connected in an
open vented manner. Refer to Australian Standard AS3500 for more details on acceptable
connection solutions.
