High Quality

Much higher quality than the flanges that come with the geyser.

Johan Odendaal
Very happy

Great quality product at a good price! Will definitely use this supplier again!

Not ideal for vertically mounted geysers

The tube seems well made and works well enough, but it does not provide a way to secure a thermostat that is inserted into a geyser that is mounted vertically. If your geyser is mounted horizontally this should be perfect. If your geyser is mounted vertically, you have to figure out a way to secure the thermostat to the geyser yourself.

Very good and on time

Good Service

• The parts were delivered quickly.
• Important to have a screw in element box spanner (suggest adding it to the description).
• I also suggest replacing the anode while replacing the element.
• Make sure the thermostat does not have the male prongs on the flange side. My thermostat plugged in directly onto my old element so had to replace my thermostat with one with fly leads.
• The thermostat does sit pretty loose in the sensor tube; I used some insolation tape to keep it pressed in. The one concerning thing for me is the airgap between the thermostat and the water. This might cause the thermostat to perform undesirably, since the heat transfer from the water over the airgap to the thermostat will vary.
• The PTC element did initially leak very slightly from the glass cover even though the element was tightened properly. The flange did not leak at all. I left the leak and turned on the element to get it up to temperature so I could tighten it while it is hot in hope to stop the leak and it seems like it stopped leaking, I do occasionally look if droplets form.
• Lastly it does seem that the 1.5kW PTC element draws up to 1.8kW and it sufficiently heats up my 200L geyser, it did take a few hours to heat it up, but when it is on temperature (55°C in my case) it draws around 5kWh a day on average.

Sensor tube

Thermostat has a very loose fit and falls out of sensor tube
