View common questions about the post installation of iStore products
Why does water drip from the iStore valves?
All storage hot water systems need to control the pressure in the tank as the water expands during the heat cycle, it is normal for the pressure control valve(s) to drip during a heat cycle and this will cease once the heat cycle is completed. Australian Water authorities are aware of this loss and allow approximately 2% water loss during a heat cycle.
Why does water flow from the condensate drain?
Compressor technology water heaters like the iStore are constantly filling with condensation that forms on the very cold evaporator, this is identical to the operation of a fridge or an air conditioner. The condensate amount will vary depending on the humidity of the day and will cease once the heat cycle is completed.
Why is my hot water pressure reduced?
Whether it be a new installation or your iStore has been installed for some time there are a number of factors to consider.
NEW INSTALLATION:-
All appliances and fittings within an Australian home are now produced to accept a maximum pressure of 500kpa, in fact new housing developments have limiting valves just after the water meter to restrict the whole of home. This means that your dishwasher, fridge, washing machine, flexible undersink hoses etc are all protected from over pressure. The iStore is specified to have a pressure reduction valve in place to meet the design of criteria of 500kpa.
EXISTING INSTALLATION:-
Plumbing valves are susceptible to clogging if a significant volume of sediment passes thru the the pipework. Clogging of the valves may reduce the pressure delivery from the iStore but may also influence the operation also the anti-scald valve, it a significant amount of sediment blocks the protective screens at the valve the temperature of the water delivered to the house can be reduced.
There is nothing inside the iStore unit that can restrict the flow, it the pressure or delivery temperature is being effected then please call your installation plumber and discuss your concerns and possible service needs.
Does the iStore have dust filters that need cleaned?
No, there are no dust filters in an iStore to be cleaned, the evaporator inside the unit is very similar to a radiator in a car but due to the hydrophilic coating employed in an istore generally the dust does not collect on the evaporator. If you look thru the grills and it appears clear similar to the car radiator, then there is no cleaning required.
For further advice on this topic please call 1300 515 636.
Does the istore have a replaceable sacrificial anode?
Yes the iStore has two sacrificial anodes, one for whole of life and the other is the service anode. The service anode standard change schedule is 5 years for typical Australian capital city town water. Regional Australia can have harsh water and as such more frequent checks and possible replacements can be recommended by local service agents. If the Total Dissolved Solids is greater than 600PPM, the anode shall be inspected every year and replaced at intervals not greater than every 2 yrs.
