Heater Hewalex OKC400NTRR/SOL is designed for heating domestic hot water in 2 circuit systems composed of solar thermal system and a boiler.
Information about the product
Heater OKC400NTRR/SOL is equipped with 2 coil heat exchangers. Bottom coil is connected to the solar thermal system and the upper coil to the traditional heat source, such as water boiler. Additional heat source may be an electric heater - its connection is enabled through a separate pipe stub 6/4”. There is a 150mm diameter inspection hole in the bottom part of the heater, which enables maintenance and installation of additional elements.
The tank is characterized by low heat loss, due to polyurethane foam used as its insulation (50mm thick). Energy efficiency class "C" indicates a very high standard in this category and size of heaters. At the same time it allows keeping optimum relation of energy efficiency to costs of purchase and operation.
The outer jacket is made of hard plastic in grey. It is therefore more resistant to dirt and mechanical damage. Inner surfaces are made of steel and covered with ceramic enamel which protects them from corrosion. Magnezium anode is a standard equipment of the heater and provides additional protection. The heater may be placed directly on the floor and precisely levelled using adjustment tools (feet).
