Electric heating rods with M48x2 metric thread
These heating rods are designed for use in electric boilers, i.e. to be controlled by a heating system controller. These rods are available in 3x230V/400V version, with no power supply cable. As they are made of bare copper, they are unsuitable for storage water heaters. They are unsuitable also for acumulation tanks as they have a shorter non-heating end.
