5. Element installation (retrofit)
If you need to exchange the element on an existing geyser, please follow the instructions provided by the element supplier.
There are two main types of geyser heating elements: screw-in and flange type. There are three main types of thermostats: VKF-11, TSE and Thermowatt
(the TSE and Thermowatt thermostats are quite similar). The below table provides a guide to Elon® compatibility with the different elements and thermostats.

Compatible thermostat type
Comments
Screw-in element:
VKF-11 thermostat:
Element & thermostat have separate electrical
connections, so each can be connected (wired)
separately to the Elon®. Thus, this element-
thermostat combination is directly compatible
with the Elon®. (No need to use the bridging
wire or element adapter supplied with the
Elon® unit.)
The thermostat pocket in the element is the
right size for the VKF-11 thermostat.
