Boilers with immersion heaters require maintenance every 2 years: anode inspection and/or replacement (warranty condition); inspection of the heater and, if necessary, descaling. Thanks to the 580-ohm resistor connected between the heater and the inner container, the magnesium anode evenly protects both the heater and the thermos and lasts significantly longer.
The ideal solution for downpipes with a small diameter, e.g. in summerhouses and carports.
