Geyserwise Service in Gauteng is tops

My solar geyser stopped heating over the weekend. I contacted Gavin at the Gauteng office at 8 am Monday for assistance. He identified the problem and talked m through tracing the fault to a corroded connection between the solar panel sensor and the geyserwise control unit. Cut off the connectors, soldered wires together and by 11,30 am my problem was solved, at no cost! Brilliant service. Thanks from Stan.
