GEOTHERM ® WGB (P) series boilers are designed to produce hot water. Boilers are focused on heat supply of industrial and domestic facilities.

GEOTHERM ® WGB (P) series boilers are manufactured with three temperature schedules 70-95 °C; 70-110 °C; 70-150 °C.

Boilers of the GEOTHERM ® VWS (P) series are produced with a capacity from 0.63 to 58.2 MW.

The fundamental difference between the boilers of the GEOTHERM ® WB (P) series from the boilers of the GEOTHERM WEB(3P); GEOTHERM WEB; GEOTHERM WEB(V) series is that the exhaust gases after burning the torch of the burner immediately pass through the convective surface.

Main components of GEOTHERM ® WGB (P) series boilers:

  • Collector frame - serves for the distribution of water flows depending on the hydraulic circuit of the boiler and the connection of the boiler to the external strapping.

  • The convective section is the main part of the boiler pipe system.

  • The support frame serves as the base for the installation of the boiler pipe system.

  • Stiffness belt - serves as a frame to ensure the rigidity of the boiler.

  • The flue duct with an explosive valve - serves as a channel for the discharge of exhaust gases. 
The GEOTHERM WGB (P) 15 hot water boiler is not difficult to repair; if the convection panel fails, there is no need to change the entire convection unit.

Advantages of the boiler geotherm series:

High efficiency

Gas-tight tube
