ROTEX - Model GCU -Compact Gas Condensing Boiler
Made-to-measure for your home. A compact combination, flexible in application, and with outstanding efficiency. The ROTEX GCU compact combines modern gas condensing technology with a thermal store and solar storage tank in the smallest possible space.
Highest efficiency
- Energy-saving gas condensing technology with an effectivity up to 110%
Innovative technology
- Integration of boiler and thermal store
- Lambda-Gx gas-adaptive combustion system with fully electronic gas-air combination
- Intuitive electronic regulation
Domestic water hygiene
- Highest level of hygiene by separation of store and potable water
- No deposits, no legionella production
As if made just for you
- For heating and hot water
- Compact dimensions, simple installation in the smallest space
- Flexible use, direct combination with solar system or existing fireplace with water pocket is possible
ROTEX GCU compact - A perfect union of combined strengths.
Condensing boiler and thermal store with a footprint of just 0.36 m².
The GCU compact can be used as an efficient thermal store for additional heat sources. For example, in addition to a solar system, a fireplace with water pocket can be used to provide support during heating and hot water generation. If you are not installing a solar system directly, it can retrofitted quickly and easily at any time.
Dream dimensions for your heating.
It doesn’t matter whether solar energy is used or not, the ROTEX GCU compact is an optimum combination of highly efficient condensing boiler and hygienic thermal store. Through the uncompromising grouping of these functions, the GCU compact sets completely new standards with regard to extra space and energy exploitation. An area of only 0.36 m2(GSU compact 315/324) or 0.64 m2 (GSU compact 515/524/533) is sufficient to accommodate the complete heating, hot water generation and solar stratified storage tank.
ROTEX GCU compact
Save money? Definitely! Compromise? Never!ROTEX gas condensing systems let you save energy without compromise.
The storage tank is a twin layer structure made entirely from plastic. The space between the inside and outside container has excellent foam heat insulation. This extreme heat insulation ensures low overall heat losses for the ROTEX GCU compact
Energy saving: The improved storage tank and cover insulation made from PU rigid foam reduces the heat losses to an absolute minimum. This protects the environment and your wallet.
Low scaling: On commissioning, the storage tank is filled with tap water which is not exchanged during operation. Thus, only the lime contained in this water can be deposited; all the heat exchanger pipes remain free of limescale, as does the electric immersion heater, which is available as an option. On the inner surface of the heat exchanger pipes, the high flow speed when the water is removed releases smaller scale deposits.
Long-life and safe: The materials used (plastic and stainless steel) ensure the ROTEX thermal store has a particularly long life and will provide you with hygienic hot water for decades.
It‘s better to trust experience.
ROTEX has been making thermal storage tanks for optimum water hygiene for 25 years. The design of the storage tanks has been continuously optimized to ensure that the heated domestic water only stays in the storage tank. This means that neither deposits nor bacteria can arise.
