Description

Boilers of the WISE series are made of 4 mm high-quality gray iron manufactured by VIADRUS (Czech Republic). Inhibitor treatment protects the heat exchanger from corrosion. The boiler works in closed systems with the operating pressure of 4 atm maximum.

Wide model range: 16, 25, 35, 40, and 50 kW.

Used in the heating system with forced and natural coolant circulation.

Efficient operation with minimal ratio of the boiler water capacity to the heat exchanger’s weight and area.

Continuous smooth power modulation.

Possible connection of:

Indirect heating tanks;

Thermostats (chronothermostats) to control the boiler’s temperature relating the indoor temperature;

Remote home controlling systems (Android and IOS);

Outdoor temperature sensors;

External fan for forced rejection of exhaust gases;

DHW and heating system pumps.

Systems of protection against overheating, draft interruption and freezing.

Resistant to voltage variations (180 - 245 volt) and gas pressure (6 - 25 mbar).

LPG operation.

Low noise.

2 years warranty.
