KDO-E ladder radiators

						
KDO-E ladder radiators are curved – the transverse tubes are curved along their whole length and thus form a symmetrical arch. The heating rod is on the right bottom part of the heating ladder (from the user’s viewpoint).

KDO-E ladder radiators

As far as their structure is concerned, these are steel tubular units which are commonly used in warm-water heating systems. However, when these heating units are intended for use in combination with electric heating they are supplied in a self-contained state – i.e. they are equipped with an electric heating unit (heating rod), filled with an antifreeze mixture and sealed. In order to extend its life span, the output of the heating rod is approximately 30% lower than the real output of the ladder radiator. The heating unit is usually fitted with a coiled power supply cord ending in a standard plug. A ladder radiator can also function as a practical hand and bath towel dryer. As electric ladder radiators are not connected to the domestic hot water system, such systems being commonly equipped with an expansion tank as standard, the expansion of the radiator filling (antifreeze mixture) needs to be considered. For this reason, the internal volume of ladder radiators is not completely filled and approx. 10% of the volume is left free of water. When handling a ladder radiator during transport and installation, the flowing of liquid inside the radiator may be heard; this does not mean that the product is faulty.
Depending on type, the heating bodies in the ladder may (or may not) have a thermostat – either directly next to the heating rod or at the end of the power supply lead. FENIX offers ladder radiators without a thermostat as standard as such radiators are often used as part of a whole system of electric heating where master regulation is installed and a regulator on the ladder radiator would be superfluous. However, if needed, a socket thermostat can be purchased separately which can control the operation of the ladder radiator. The removal of the plug for the connection of the supply lead to a wiring box is not a reason for voidance of warranty. Ladder radiators always have to be installed in a vertical position, with the heating rod in the bottom part.
