The standard series of wall-mounted THERM EL electric boilers includes 6 models with various heating outputs. Due to the nominal heating output from 7.5 kW to 45.0 kW for individual models, they are often used as heat sources in recreational areas, family houses and industrial buildings. The construction and technology used enables to include electric boilers into the common system, the cascade boiler rooms and to cover large heating losses of the building. An intelligent cascade boiler room may include up to 32 boiler units (with various outputs).
Similarly as with the other electric boiler models, this series provides significantly simple boiler operation and fluent regulation of the output in slow steps of 2.5 kW (5 kW for boilers with a heating output over 30 kW). There are also the options to heat utility water in an external storage tank after fitting with a three-way valve, remote administration through SMS messages and regulation according to space or outdoor temperature (equithermal regulation), etc.
