Boiler Use and Advantages
The boiler HERCULES U 32 meets the requirements for heating of houses, shops, etc.
The boiler is manufactured as hot water boiler with natural and forced circulation of hot water and working overpressure up to 400 kPa (4 bar).
Before dispatch it is checked for tightness with the test pressure of 800 kPa (8 bar).
The boiler is designed for heating in both closed and open heating systems.
The Boiler Advantages:
1. High service life of cast iron exchanger and all other parts due to the quality of the materials used.
2. Long-term proven design.
3. Sophisticated manufacturing technology on the automatic forming lines with consistent and approved quality of the production process (ISO
9001, ISO 14 001).
4. Combustion efficiency 86,5 - 90 %.
5. Low fuel consumption.
6. Simple operation and maintenance.
