iStore Basics

The iStore utilises an ingenious technology to efficiently transfer thermal energy directly from the surrounding air and into water, without dependence of the sun or fossil fuels to provide an energy source.

iStore Air to Energy Solar Hot Water System

Characteristics

Smart and efficient unit
The operational costs can be up to 75% less than that of an electric water heater, and can be installed in locations which are unsuitable for solar hot water heating.

Safe and environmentally friendly
Produces no harmful gases along with no open flame, making the unit safe to work with when installing.

Easy to operate
Featuring an easy to use timer for both start and stop operations, with a controller to set the desired water temperature.

How Does The iStore Work?

iStore Air to Energy Solar Hot Water System - How Does The iStore
Work

  1. A fan draws in air, containing heat energy, across the evaporator
  2. The evaporator turns the liquid refrigerant into a gas
  3. The compressor pressurizes the refrigerant into a hot gas
  4. The hot gas inside the condenser coil heats the water inside the coil-wrapped tank
  5. The refrigerant reverts back to a liquid after heating the water and continues to the evaporator for the process to start again
  6. The cycle continues until the set target temperature is achieved

As water is used in the home, the cycle will restart once the temperature in the lower section of the tank has dropped 11 degrees below the target temperature.

HOT WATER CAN CAUSE SERIOUS INJURY

WARNING – Hot water is dangerous!
As a safety precaution, young children should always be supervised around hot water fixtures

THIS WATER HEATER IS ONLY INTENDED TO BE OPERATED BY PERSONS WHO HAVE THE EXPERIENCE OR THE KNOWLEDGE AND THE CAPABILITIES TO DO SO. THIS WATER HEATER IS NOT INTENDED TO BE OPERATED BY PERSONS WITH REDUCED PHYSICAL, SENSORY OR MENTAL CAPABILITIES I.E. THE INFIRM AND CHILDREN.

As solar water heaters can generate water temperature in excess of 50o C, regulations require that an approved solar rated tempering valve shall be installed in accordance with the valve manufacturer’s instructions. This is required to prevent water temperatures supplied to the house exceeding a preset safe maximum. The tempering valve is connected to the hot water outlet lines. The valve must be fitted by an authorised plumber at the time of installation or in retrofitting to existing systems.

CHECK THE WATER TEMPERATURE BEFORE USE, SUCH AS WHEN ENTERING A SHOWER OR FILLING A BATH OR BASIN, TO ENSURE IT SUITABLE FOR THE APPLICATION AND WILL NOT CAUSE SCALD INJURY.

Hot water systems can store water at temperatures that can cause scalding. Water temperatures over 50oC can scald and care needs to be taken to ensure that injuries do not occur through incorrect use of your water heater.

If the water heater is left unused for two weeks or more, a small quantity of hydrogen gas (which is HIGHLY flammable) may accumulate in the top water cylinder. To dissipate this gas safely it is recommended that a sink or bath hot tap be turned on to dispel a couple of litres of water. During this procedure there should be no smoking, open flames or any electrical appliances such as washing machines or dish washers operating nearby. If Hydrogen is discharged through the tap, it will make a sound like air escaping.

GENERAL SAFETY INSTRUCTIONS

The installation of the iStore solar hot water systems requires the expertise of a licensed professional. The installation process must adhere to the guidelines set forth in the National Plumbing code (AS/NZS 3500.4), Australian Electrical Wiring Rules (AS/NZS 3000), as well as all applicable local plumbing and electrical regulations.

The electrically operated components of this water heater operate on 240v AC power.

The removal or attempted alteration of any electrical component must be conducted by a qualified electrical service person.

Care should be taken to avoid coming into contact with any pipe work or fixtures associated with the water heater.

For continued safety of this appliance, it must be installed, operated and maintained in accordance with the manufacturers instructions.

NOTE: IF YOU ONLY REQUIRE 1 TIMER THEN YOU MAY LET THE TIMER FUNCTION TIMEOUT AND THE SECOND TIMER WILL REMAIN BLANK WITH “–:–” VALUES.

If you require a second timer then tap the clock button again and step through setting the ON 2 and Off 2 times in the same manner as described above.

Important Information

For units manufactured from January 2023 ignores timers with the same start and end time, that is 00:00 on through 00:00 off will not activate as 12:00 on thru 12:00 off will also not activate.

On and off times should have differing minutes also to ensure the desired period is achieved.

For example for a full daytime timer a start of 10:00 on thru 16:00 should have the minute increased to 16:01 to confirm the timer window operation.

For units manufactured prior to January 2023 do not set the second timer to 00:00 ON and 00:00 OFF as the unit will commence heating at midnight every second night.

Home Owner Maintenance

Temperature and Pressure Relief valve PTV/PTR (all tanks)
The iStore hot water system is fitted with an 850kPa PTR Valve, which is located on the side of the cylinder and is essential for its safe operation. It is important that you operate the easing knob or lift the lever on the PTR valve once every 6 months. It is important you rotate the knob or lever gently so seat is not damaged.

Expansion Control Valve (ECV) (if applicable)
In some states and local councils, the installation of an Expansion Control Valve (commonly referred to a cold-water expansion valve) is required to be installed. If this valve is fitted, follow the same procedure for PTR valve as explained above.

Condensation line
Regularly inspect the condensation line to ensure water is dripping freely for the line. If the condensate drain is blocked at the discharge end, clear any debris that may have collected in the line. During normal operation, condensation occurs from the transfer of air across the evaporator coil. This process is drawing humidity from the air and creates condensation/ water droplets on the coils, which in turn is captured in the fully moulded condensate tray and discharged through the condensate drain line. In locations with humidity greater than 80%, up to 5 litres per day can be expected under normal operating conditions.

Obstructions
Regularly check the no obstructions are interfering with the air in-take or air discharge. If unit is installed near shrubs or trees, keep them trimmed so they do not interfere with air flow.

Insulation
Your installation by a licensed plumber should’ve included UV stable insulation. Periodically inspect the insulation to ensure that no deterioration or damage by external influence has occurred.

Note: Up to 60% heat loss can occur if the insulation is non-existent or substandard. Therefore, please pay particular attention to making sure the system is properly insulated and any external insulation is UV Protected.

iStore hot water tank ­ 5 year service ­ Authorised/licensed plumber

The five-yearly service should be carried out by a licensed tradesperson. It is recommended that this service be carried out by your local iStore agent. The service should include the following:

  1. Replace the pressure & temperature relief valve.
  2. Replace the anode (anodes should be replaced more frequently if subjected to hard water conditions, refer table in the warranty exclusions, iStore must be consulted regarding the replacement anode if not a genuine iStore anode). If the TDS is greater than 600PPM, the anode shall be inspected every year and replaced at intervals not greater than every 2 yrs.
  3. Flush the water heater.
  4. Clean air filters thoroughly.
  5. Replace tempering valve if specified by valve manufacturer.
