I "Googled" USB-loggers. They're a bit limited, and the really useful ones are far too expensive (±$500 )windgat wrote:USB logger - I imagine there are devices out there which record various inputs (like amps, volts etc) which you can later connect to a USB port and download all the data for analysis on a PC.
Agree. I've decided to buy a new kWhr-meter and install it at the geyser permanently.windgat wrote:Probe sounds a hassle - and it needs to be deep in the water to get the core temp. As you say, maybe its less important than the power.
Correct. Perhaps we can also ask the manufacturers for info.windgat wrote: We could test a thermostat to find the hysteresis, and then we would know the on and off temperature points, so the current would tell us the temperature at the thermostat on and off points. That would be enough to get the model perfectly tuned.
