Gas condensing boilers

TGB-2

The WOLF TGB-2 gas condensing heating system is the quietest on the market. It will also heat your home particularly economically as the appliance continuously adjusts its output to meet your current demands.

A gas condensing boiler for any installation site

Flexible flue gas connections and simple installation make the TGB-2 the ideal gas condensing boiler for replacing existing boilers.

The TGB-2 is available in two different ratings: the TGB-2-20 with 20 kW output and the TGB-2-30 with an output of 30 kW. The TS-160 stratification cylinder or TR-160 indirect hot water cylinder are both ideal additions. Combining these with a mechanical ventilation unit forms a complete building services centre.

The gas condensing technology is equally suited to new homes and heating modernisation projects.
