 TOPIC: Keep your water hot and reduce energy consumption.

 CASE STUDY: 56 Jackson Street, St Kilda : Community House Apartments

 AUDIT: Rheem Solar hot water system inspection

 EXISTING System :

 –        Rheem Commercail solar lo-line system 

–        3x Rheem NPT solar collectors

        Rheem 610340 storage tank

        Rheem 631275 duty gas system boost unit.

 FINDING 1 :

        roof inspection: solar array well installed, new pipe insulation required, existing lagging worn causing heat loss

        solar sensor cable: requires plastic conduit to protect from weather

        plant area on ground: requires new pipe insulation on exposed heated water lines.

ACTION: all current insulation on pipes needs to be replaced to protect from the weather and prevent  heat loss.

FACT: For every 1 meter of poor insulated hot water pipe there is a 1 degree Celsius drop in water temperature. Therefore the system at Jackson Street is heating at 680C  but by the time it reached the tap it has lost 120C.

 FINDING 2 :

        Grundfos circulators 20mm: need timers

        hot water heating: circulators are operating 24 hours a day.

 ACTION: Fit a Kambrook dial timer to heat hot water during peak times (10 hours per day)

 FACT: Circulating the hot water around the ring system 24 hours a day causes significant temperature loss and unnecessary energy consumption. By operating the recirculation pumps for only 10 hours every 24 hours, there will be a significant drop in energy consumption.
