Floor-standing, gas-fired WTC-GB condensing boiler

The WTC-GB: a new generation of floor-standing, gas-fired condensing boilers from Weishaupt for ratings from 90 to 300 kW.

The WTC-GB: a new generation of gas-fired condensing boilers from Weishaupt, rated from 90 to 300 kW, or up to 1200 kW in a cascade, that has been developed especially for the heating of larger buildings. The new model considerably increases the range of applications open to Weishaupt gas-fired condensing boilers.

Inside the boiler the highly resiliant surface of the cylindrical pre-mix radiant burner ensures the homogenous air/gas mixture is combusted with minimal emissions. The WTC-GB's heat exchanger benefits from outstanding heat-transfer properties. A special sandcasting process produces the highly efficient heat-transfer contours that result in the optimal conversion of supplied energy into heat. The perfectly tailored combination of heat exchanger and controller facilitates a modulation bandwidth of 1:6. The nominal nett efficiency of 109.4 % (98.6 % gross) is an indication of the boiler's outstanding fuel utilisation.

The boiler's low energy consumption is not its only key feature; its operational reliability and reduced servicing and maintenance requirements are also noteworthy:
- A gas-pressure switch, which allows an automatic restart after an interruption to the gas supply, is included as standard.
- There are separate ducts for high and low-voltage electrical connections in order to avoid interference.
- The Thermo Condens Manager's diagnosis system enables the prompt identification of incorrect settings or of the causes of possible adverse affects on heating operations.
- The heating gas channels are readily accessible, thanks to large inspection openings in the heat exchanger and flue gas manifold, and can be quickly and easily cleaned whenever required.

The floor-standing Thermo Condens gas-fired condensing boiler is supplied ready for immediate connection on site. The boiler can be brought into the boiler room with ease thanks to its compact dimensions, low weight, and welded handling aids. All of the connection points are located on the rear of the boiler. They can be readily accessed and are arranged in installer-friendly positions.

System accessories for trade customers have been added to the product range along with the condensing boiler, including the versatile Weishaupt flue-gas/air system. It is ideally suited to the installation advantages presented by the WTC-GB's low-set flue-gas connections.
