Heating technology

You will quickly be won over by the inner values of the new CGB-2 series of condensing boilers from Wolf. The efficiency concept has moved on from the previous series, and now offers four notable benefits: 1. The self-calibrating combustion controller that adapts to the prevailing gas quality means that the gas:air mixture needs never to be adjusted again. This also applies to changing gas qualities (e.g. if biogas is mixed in). Furthermore, the system can modulate down to a minimum output of 1.8 kW. This translates into fewer burner starts, extremely clean combustion and the highest level of...

More versatile than ever – better than ever CGB-2 series – state of the art condensing technology The new CGB-2 wall mounted gas condensing boilers are worthy successors to their consumer test winning predecessors. With output levels of 14, 20 or 24 kW, they offer the best possible solution for a wide range of buildings. What makes these appliances so special is the electronic, gas-adaptive combustion controller that adjusts automatically to the prevailing gas quality. Users will also enjoy the low standby losses and high efficiency, while the environment will benefit from the extremely clean...

High-tech successor to the Wolf test winner CGS‑2L – the floorstanding solution with stratification cylinder technology The CGS-2L gas condensing centre is the larger version of the CGB-2 wall mounted gas condensing boiler. Similar benefits are on offer. As was the case with the previous model, the CGS-2L comprises a wall mounted gas condensing boiler with stainless steel DHW heat exchanger and a stratification cylinder. All these parts are assembled into a practical and compact module, which can be split into units of 35 kg and 49 kg. Further benefits to remember: • Booster for DHW heating and...

The perfect solution for direct replacement of wall mounted appliances CGW-2L – there's no faster way to upgrade The CGW‑2L wall mounted gas condensing centre comprises a CGB‑2 gas condensing boiler with stainless steel DHW heat exchanger and a stainless steel stratification cylinder with special thermal insulation. Just like the floorstanding solution, the CGW‑2L offers high levels of DHW convenience in a small space – with the added benefit that it is mounted on the wall. This appliance, which is designed for easy separation into two easyto-handle modules of 35 kg and 19 kg, is fully wired...

The perfect combination of gas and solar The CSZ‑2R gas condensing solar centre was also developed and equipped according to the condensing efficiency concept. As a result, the CSZ‑2R can cover up to 60 % of the DHW heating with solar energy, making it the perfect system solution. This compact, modular and visually appealing solar centre comprises the following: CGB-2 gas condensing boiler, BM-2 programming module, solar cylinder, solar pump assembly with high efficiency pumps and SM-2 solar controller, 25 l solar expansion vessel and collecting vessel for the solar fluid. The solar cylinder...

State of the art oil condensing technology Heating with oil was never more economical than with the TOB The TOB is based on the same general principle as the COB – the German consumer association "Stiftung Warentest" test winner. However, Wolf development engineers have now been able to improve the burner unit even further. The most pertinent new development concerns the use of the modulating combustion principle that employs pressure vaporisation and the patented mixing swirl nozzle. Oil preheating and oil evaporation are not required, which saves on auxiliary power consumption. During combustion,...
