Question 1

Why does the iStore not heat as soon as I use any water?

Bill Allison · Accepted Answer

The Federal Government Clean Energy Regulator specifies the thermostat range of all iStore style compressor hot water systems, the thermostat range is 12 degrees, this means that the bottom of the tank must fall 12 degrees below the target temperature before the heating cycle begins. The hot water delivered to the house is from the top of the tank as natural convection causes the hot water to rise to the top of the tank all of the hot water is available for use.
