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.
- Equipped with original components of gas burner units and SIT gas valve, as well as POLIDORO injection microflame burner.
- 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.
