A wall-hung gas boiler with maximum efficiency for heating and hot water generation. Available in two versions with DHW heating in the flow principle or in combination with a hygienic thermal store for maximum drinking water hygiene and hot water comfort.
Space-saving and quiet
Most comfortable technology in the smallest space.
For the health of your family
Hygienic water heater principle or combination with a ROTEX heat storage with fresh water technology.
Simple, convenient, individual
For variable use there are 3 performance classes.
With the room control, you control intuitively all functions of the ROTEX GW.
State of the art condensing technology converts fuel into available heat with virtually no losses. Flue gases are cooled until the water vapour they contain has been condensed. The energy generated is used as heating energy. This makes gas condensing boilers up to 20 % more efficient than standard boilers.
The ROTEX GW gas condensing combination boiler offers the most convenient technology in the smallest space with maximum efficiency for hot water and heating. The hygienic generation of hot water is carried out on the instantaneous heater principle (version C). Thanks to energy-saving condensing technology, the ROTEX GW achieves an effectivity of up to 109 %. Simplest operation and installation as well as quiet running characterise the ROTEX GW.
The ROTEX GW offers two output ratings and versatile flue gas technology installation variants for variable applications. It can operate using both natural gas and bottled liquid gas. The ROTEX GW is characterised by its many convenience functions.
All the information about the operating status and temperatures can be called up very easily – using the remote control on the ROTEX GW and even by remote request. Weather-controlled electronic regulation can be included upon request. In addition, it has a weekly timer programme (up to 4 heating phases per day, individually selectable), a motion sensor and holiday function, many ecofunctions and automatic summer/winter changeover.
For DHW heating, you can opt for the hygienic instantaneous water heater principle (version C) or use the boiler in conjunction with the ROTEX Sanicube high performance thermal store for maximum DHW hygiene and convenience (version H).
1. The combi boiler (version C): In the instantaneous water heater principle, the device ensures the heating of water for heating and for DHW..
2. Combined with a thermal store (version H): For a higher DHW demand, we recommend using the boiler in conjunction with a thermal store. The ROTEX Sanicube represents a combination of domestic hot water tank and instantaneous water heater. The water to be heated is routed through and heated by a separate high performance stainless steel heat exchanger. The Sanicube therefore offers outstanding benefits in terms of water hygiene.
The ROTEX GW is characterised by high hot water output and high level of consumption water convenience. The modulation ratio of 1 : 5 (100 % : 20 %) ensures optimum adaption to the individual performance requirements. The unit exhibits the NOX class 5 and is operated for maximum efficiency in a room-air independent manner. An integrated safety group is also included in the scope of delivery, as is a flue gas test adapter.
All ROTEX products are tested and meet the criteria of the Ecodesign Directive. For both individual products and packaged solutions, energy labels are a reliable indicator of the precise efficiency class. Perfectly matched in terms of their individual components, our complete systems provide both maximum convenience and the highest safety standards. .
