Guidelines on installing temperature sensor on a geyser (TAKEN FROM DIY ENTHUSIASTS DO AT OWN RISK)

There are 4 ways for probe positioning to monitor geysers temps:

1. Stick WTS01 Sensor onto flange at thermostat or drill small hole in plastic end cover of geyser, use screwdriver to push through insulation till feel geyser shell, continue along shell for 100mm or so, remove screwdriver and insert probe along channel created – nestling under insulation against shell is as good as inside.
2. Replace existing thermostat with WTS01 Sensor – not recommended when going to do switching since no equipment is ‘safe to fail’ but if only for monitoring like in solar water or for heat pumps then 100%
3. Attach WTS01 Sensor to hot water out pipe on top of geyser and cover with insulation
4. Install dedicated probe pocket – can buy from solar water providers – bit more difficult and skills required then add the WTS01 Sensor to the probe pocket
