These PTC elements are generally very reliable and long lasting. PTC elements such as the ones sold by GEYSERWISE present some real benefits compared to traditional resistive heating elements:
- Saves you up to 15% electricity
- Safer operation thanks to the self-limiting temperature characteristics of PTC technology used in the element
- Dry burn tolerant: can operate in dry air without overheating
This PTC element can be fitted on the following geysers:
Tecron, Duratherm, City Heat, Franke, GAP, Heat Tech, Kwikot and Xstream.
Each type of geyser may require a different flange and sensor tube. You can find more details for each geyser brand retrofit on the EcoDepot website.
How to replace your geyser heating element by a Geyserwise PTC element
What you will need:
- PTC element
- Flange and sensor tube
- Portable screwdriver
- Size 10 allen key
Switch off the power supply by the isolator switch (this should be within 1 meter of your geyser) and switch off the geyser switch at the distribution board (db).
Turn off the stop cock, this will turn off the water supply inlet feeding your geyser. If you don't have one close to your geyser, switch off the mains.
Drain the geyser. There is a drain cock to drain your geyser, but if you can't find/access it, you can drain it using a standard pipe.
Remove the lid and loosen the screws to disconnect the existing element and thermostat, by removing the wires (phase, neutral, earth).
Remove the flange plate and flange rubber gasket, and replace it with the new flange and rubber gasket. Then, tighten the nuts.
Use a geyser element spanner to screw the element and the fiber joint, tighten it fully to prevent any leakages. Then insert the sensor tube.
Insert the sleeve of the thermostat and tighten with an allen key (size 10). When it is fully tightened, connect the thermostat and the element.
Connect the phase (red wire) from the insulator switch to the left side of the thermostat. Also connect the phase of the element (red wire) to the right side of the thermostat.
Connect the black wire of the element (neutral wire) by the connector block to the neutral wire coming from your isolator switch.
Connect the green and yellow wires (earth) to the new flange.
Screw the lid back on (ensure the isolator switch is turned off).
Turn the hot water tap on.
Turn on the water supply of the geyser to fill it up. Air will come out of your tap. When the water comes out, turn it off. Check for any leaks around your geyser.
Switch on isolator switch and geyser switch at the db.
