Is anyone able to help with a problem I have with my two geysers. I have a large one supplying the main bathroom, kitchen and outside bathroom. The second smaller one supplies the ensuite. I want to tun off the small geyser and operate with only the large geyser. I have two ripple meters and two trip switches, one for each geyser. I have tried turning off the trip switch for the smaller geyser and it results in all the hot water in the house becoming cold. I have put the trip switch back on and turned off the large geyser trip switch and all the water in the house becomes cold. I have had two electricians and a plumber trying solve the problem. The geysers are not in series. I would really appreciate any help. Thanks. Glynischeryl.
