Description

The firing output ranges are 44–200 kW for WTC-GB-210-A, 48–239 kW for WTC-GB-250-A and 53–276 kW for WTC-GB-300-A, and all run on natural gas of groups E/H and LL. The maximum standard seasonal utilization factor reaches 110.3 % based on the lower and 99.4 % based on the higher heating value, and the heating energy efficiency class is A. The width of the boilers is 680 mm, the height 1205 mm, and the weight is 212, 225 and 242 kg respectively. Up to four WTC-GB 300 boilers are combined in a cascade of up to 1200 kW, and hydraulic separation of the systems is provided for single boilers and cascades. The electronic monitoring system uses sensors in the flue gas, supply and return lines and a low water switch, and flue gas and air pressure switches are built in as standard. A built-in intake silencer reduces noise (210 kW model). Control is possible from the remote station WCM-FS with a backlit four-line display, and additional interfaces connect the boiler to building automation.

How to choose

The model is chosen by the firing output and the number of boilers. For 44–200 kW WTC-GB-210-A is suitable, for 48–239 kW 250-A, for 53–276 kW 300-A. If more is needed, up to four 300 boilers are assembled in a cascade of 1200 kW. For outputs above 276 kW per boiler look at WTC-GB 470 / 620, and for small buildings WTC-GW / WTC-GB 45–150.
