instantaneous water heaters

1. Purpose and characteristics

PERFECT 3.5 – 5.5 MIX instantaneous water heaters are designed to supply hot water to such
sanitary devices as sinks and washbasins in households, washrooms, bathrooms, workshops and
catering outlets. Thanks to the electronic system controlling the performance of the heater, all most
unreliable mechanical parts such as a membrane and switch contacts, which are used in this type
of heaters, have been eliminated. This way, the reliability and durability of the devices have been

cantly improved. The water heater can only be connected to the cold water pipe.
