With the Viessmann Vitodens 050-W Combi Boiler, Viessmann now offers an attractively priced wall mounted gas condensing boiler with proven quality. An extensive range of accessories makes the Vitodens 050-W equally suitable for either new build or modernisation. It is offered with two DHW output ratings (5.9 to 29 and 8 to 35 kW), as a combi boiler with an integral instantaneous water heater. An electronic boiler control unit for thermostatic mode and weather compensated mode is already integrated into the Vitodens 050-W, along with a frost stat. The outside temperature sensor is available as an accessory. The Vitodens 050-W features a particularly low level of operating noise and its components are accessible from the front for ease of service and maintenance. With a height of only 707 mm, the Vitodens 050-W is one of the smallest wall mounted boilers in its class. Its compact dimensions recommend it as a replacement for outdated boilers in multi storey buildings – including up to five boilers on different floors connected to one vertical flue system. Inox-Radial heat exchanger and cylinder burner made from stainless steel The high quality stainless steel Inox-Radial heat exchanger efficiently converts the supplied energy into heat. Its efficiency (to DIN) is 97 percent (Hs) [gross cv] or according to SEDBUK > 89.1 % (2009). The stainless steel cylinder burner therefore consumes relatively little natural gas, with lower CO2 emissions and less impact on the environment as a result.
