100 collectors supply a hotel with hot water Bosch realises large-scale solar thermal system in Bangalore Over 30 tons of carbon saved annually

  • Planning, installation and commissioning of a plant with a total output of approx. 150 kilowatts
  • 208 square metres of collector surface
  • Information events and training for Bosch partners
Bangalore (India)/Wetzlar (Germany) – Bosch Thermotechnoloy has taken a large-scale solar system into operation in Bangalore, India. A total of 100 solar thermal collectors from Bosch now afford maximum hot water comfort in the “Novotel Bengaluru Techpark”, a business hotel in the South Indian city of Bangalore. The project was realised under the Renewable Energy Solutions Programme initiated by the German Energy Agency (Deutsche Energie-Agentur GmbH  dena) and sponsored by the German Federal Ministry for Economic Affairs and Energy (BMWi) under its Renewable Energies Export Initiative.

About one third of the hotel roof is now covered by rack-mounted collectors. The solar heat is stored in a 6,000 litre buffer tank, which supplies the hot water to the 215 hotel rooms, the restaurant kitchens and the in-house laundry as needed. Before the system was taken into operation, water was heated by a diesel generator, which consumed about 17,000 litres of fuel per year. The phasing out of public fuel subsidies and the deregulation of the Indian diesel market made this form of hot water generation especially uneconomical.

The solar thermal system from Bosch was taken into operation in December 2014 and has since covered about half of the hotel’s hot water requirements – also at peak load times. In the first six months of operation, some 4,700 litres of diesel and, consequently, 15 tons of carbon were saved – which adds up to about 30 tons for a full year.

Bosch partners use the system for information and training purposes
The new solar thermal system from Bosch is great benefit not only in environmental and economic terms. It also benefits Bosch’s partners such as engineers, planners, architects and, most importantly, local installers, who may regularly use the system for training purposes and information events. This underlines the importance of the growing Indian market for renewable energy, while at the same time providing the knowledge and expertise required for the installation and operation of solar thermal systems.

Passion for power Bosch Industriekessel is celebrating its 150th company anniversary From a boiler manufacturer to a system supplier

This year Bosch Industriekessel is celebrating its 150th company anniversary. The company started as a small boiler manufacturer under the Loos family name. In the past decades it developed to a the leading global system supplier for industrial boilers. Since its foundation the company time and again revolutionised the heat and process energy technology in the large performance range: New and further developments continuously improved the efficiency and the durability of boiler systems.

The product range today comprises in addition system combinations with integration of combined heat and power units and renewable energies as well as products for waste heat utilisation. Internally developed, intelligent controls and web-based remote functions facilitate a higher energy efficiency and provide for an optimum interaction of different energy generators. Passion for power – this is our guiding principle. "We are building on a solid foundation that we have created in the past decades. For the future it is of high importance to use and to network energy much more efficiently. To achieve this we are developing concepts, we are offering system solutions and we are conducting research and development," explains Markus Brandstetter, managing director of Bosch Industriekessel GmbH.

The history of the company begins in 1865, when Philipp Loos founded the "Dampf-Kessel-Fabrik PH. LOOS" in Neustadt an der Weinstraße (Palatinate). In 1917 today's headquarters in Gunzenhausen (Bavaria) came into being in order to develop a series production of vertical steam and hot water boilers. The boilers from Loos proved to be successful on the market. New production locations were established in Schlungenhof near Gunzenhausen in 1958 and four years later in Bischofshofen, Austria.

Advantage through innovation
In 1952 Loos developed and patented the horizontal three-pass flame tube/smoke tube boiler with internal water-flushed rear flue gas reversing chamber – today market standard worldwide. During the course of its history the boiler manufacturer brought further innovations on the market that today still are setting benchmarks in the industry. In 1977, for example, the company developed a fully automatic water level control for a 72-hour operation without permanent supervision. Further procedures and boiler system modules e.g. for water treatment, heat recovery and PLC-based control technology followed. These components optimised not only boiler operation but also greatly facilitated system planning and installation.

High quality boilers from Germany and Austria
In the past, boiler pressure vessels were laboriously joined with rivets. The introduction of the welding technique at the beginning of the 20th century lead to significant quality improvements and optimised working processes. In 1966 Loos introduced automation into production and as the world's first boiler manufacturer the company used an numerically controlled flame cutting machine for plate cutting. Today state-of-the-art-manufacturing and testing facilities, welding robots, laser cutting machines and X-ray chambers in connection with the expertise of the specially trained employees ensure the highest in quality and perfection. Up to 1 800 customised industrial boilers per year with transportation weights of up to 108 tons leave the production facilities in Germany and Austria.

Globally active
Over 115 000 systems in more than 140 countries: When Bosch Industriekessel talks about its market today, then this is a trip around the world. In the 1980s already first sales subsidiaries were established outside Europe, for example in Asia. Due to the continuous expanison of our sales and service networks at home and abroad the export share currently makes up more than 60 percent.

The 150th anniversary – a joint success
150 years after the foundation of the company Bosch Industriekessel looks back with pride on this eventful history, characterised by technical revolutions and innovations. The partnership and the trustful cooperation with planners and plant construction companies as well as the expertise and the passion of around 700 employees have significantly contributed to this success.

Leading smart heating supplier Bosch Thermotechnology on the growth track Sales revenues climb 7% from January to May

  • Glock: „Excellently positioned for EU energy label thanks to energy-efficient systems technology“
  • Joint venture with Midea for air-conditioning systems
  • New generation of devices is web-enabled and intuitive to operate
Stuttgart – Bosch Thermotechnology has grown strongly between January and May. Sales revenues in the first five months of 2015 were up by 7% on the same period of the previous year. “The past years have seen us make massive investments in the development of innovative technologies and we more than doubled our respective budget over the past ten years. This is now paying off. More than 100,000 networked products sold make us the leading supplier in the smart heating market,” said Uwe Glock, Chairman of the Bosch Thermotechnology Division, on the occasion of a business press meeting in Stuttgart. Bosch Thermotechnology is also making progress in the CPI (Commercial, Public, Industrial) business. The joint venture with Midea for VRF (variable refrigerant flow) air-conditioning systems agreed in March represents a major step forward on the way to becoming an international systems supplier. Cogeneration solutions such as combined heat and power (CHP) units are another field of growth. At total efficiency rating of over 80% means that the carbon-friendly CHP technology is much more energy-efficient than the separate generation of heat and electricity.

“On the way towards thermotechnology of the future, we rely on three business segments, namely heating systems for residential buildings, water heaters as well as commercial and industrial heating and air-conditioning systems. We are making good progress in all three segments and want to outgrow the market,” said Uwe Glock.

State-of-the-art gas condensing technology enables highest energy efficiency
Bosch Thermotechnology is the world market leader in heating systems for residential buildings. “Gas will be the most important source of energy in the coming decades,” said Uwe Glock. Thanks to its high efficiency of up to 99% and its good availability, gas condensing technology has become the standard heating technology in residential buildings. Combined with other energy sources in a hybrid system, it can increase the energy efficiency by up to 50% compared to old devices. Buildings account for 40% of the global energy consumption, with electricity representing only a minor portion. Heat generation holds the greatest energy efficiency potential. Over 70% of the heating systems in Germany use obsolete technology. If all heating systems in Germany were converted to condensing technology, carbon emissions could be reduced by 50 million tons per year. This is the most simple and most effective lever to reach the climate targets.

A milestone in design and technology
At the ISH in March, the world's leading industry event, Bosch's thermotechnology brands Junkers/Bosch and Buderus presented revolutionarily simple and forward looking generations of devices for the top segment. The innovative modular concept and the well-thought-out layout of the components afford excellent access to the individual components inside the device. In addition, the devices can be expanded retroactively. The new design of the devices is particularly striking, featuring bold glass fronts in black or white. Developers and customers have jointly broken new ground in terms of design and haptics. “Our devices not only look good but will also change the market; their installation is up to 30% faster, they can be networked and are easy to operate via the touch screen,” said Uwe Glock. The first devices of this series will be launched in October 2015. The next technological milestones will be gas heat pumps for single and two-family homes in 2016 and the second generation of the fuel cell heating system in 2017.

Products for every customer requirement – also on an international scale
Bosch Thermotechnology relies on customised products also to cater to the different consumer requirements and conditions in the growth markets outside Europe, primarily China, Russia and Turkey. Take for instance the LCK mini heating boiler for the Chinese market, which is so small that it fits into an upper kitchen cabinet. Bosch is the only European manufacturer to produce gas condensing boilers for the Chinese region and is the local market leader in this segment.

The leader in smart heating
100,000 networked products make Bosch Thermotechnology the leading supplier of smart heating solutions for greatly increased comfort, energy efficiency, operational safety and service quality. The new “HomeCom” portal, for instance, provides installation firms with detailed information about the networked heating systems of their customers, including operating problems and their potential causes. The end user gets clearly presented information about their system as well as consumption data and individualised energy efficiency tips.

Excellently positioned for the EU energy label
Starting September 2015, all heating devices and systems must bear an energy label, which shows their efficiency in classes from A++ to G. “Our energy-efficient systems mean we are excellently positioned to benefit from the European energy label for heating systems,” said Uwe Glock. The label for individually composed systems must be calculated by the installer, whereas systems suppliers can supply pre-labelled packages. “The new energy label will open up good opportunities especially for systems suppliers like our company, as we can give the installer especially effective support. We provide them with pre-labelled, ready-to-sell systems. We expect this customer focus to pay off,” said Uwe Glock.

Leading market position in the international hot water market
The international domestic hot water business is characterised by attractive growth rates but also by regional differences between requirements and preferences. Bosch Thermotechnology’s regional positioning in this segment forms the basis for further growth. The company is currently building a new production facility for instantaneous gas water heaters in Tepotzotlan, Mexico, from where Bosch Thermotechnology will serve the Latin American market. Solar thermal collectors for the region are also produced in Brazil. In Europe, Spain and Portugal are the large domestic hot water markets, which are supplied by Bosch Thermotechnology’s production facility in Portugal. Africa has also become an interesting domestic hot water market, where Bosch Thermotechnology benefits from the geographic proximity to the Portuguese production plant. For the Asia/Pacific region, Bosch Thermotechnology produced instantaneous water heaters in Shanghai and solar thermal systems in Bangalore.

Aiming to become a systems supplier for CPI systems
Bosch Thermotechnology delivers industry-specific energy concepts and systems solutions for the heating and air-conditioning of commercial buildings and Industrial facilities. With 150 years of experience and more than 110,000 industrial boilers sold in over 140 countries, Bosch has unique knowledge of the specific requirements of different sectors and operators. The VRF air-conditioning systems for commercial buildings produced in a joint venture with Midea have added another important technology to the systems portfolio. Customers get innovative and customised solutions – from planning to remote access/service. The Master Energy Control System, for instance, combines the steam, hot water and electricity generators from Bosch Industrial into intelligent systems: the direct communication between the system components such as the CHP unit and the steam boiler results in increased system efficiency and extends the life of the system. Complex systems may be remote-controlled down to individual assemblies.

Intersolar Europe 2015 (June 10-12) Smart Bosch solutions for efficient energy systems Intelligent networks for producing and storing electricity and heat

  • Connected energy solutions for industry, commerce, and households
  • Simple to operate and monitor with smartphone and tablet
  • Greater convenience, improved energy efficiency, lower costs
Stuttgart/Munich – At Intersolar Europe 2015 in Munich, Bosch is presenting connected solutions that help industry, commerce, and households produce and store energy in a smart and efficient way. These solutions enhance convenience for users while saving them energy and money. Bosch provides a broad range of technology and service solutions: solar inverters, storage solutions, connected heating systems and heat pumps, smart thermostats, and CHPs.

Connected energy solutions for private households
Bosch is showcasing a way to optimize the use of solar power in the home: an intelligently networked energy system comprising an inverter and heat pump and managed with the e.Control unit. The heat pump, which runs on surplus electricity, takes heat from the ambient air, water, or the ground and converts it into power for heating or hot water. This combination of electric and thermal energy helps alleviate pressure on the power grid. An e.Key data card enables the contactless installation of Bosch’s BPT-S string inverter – already certified for 12 countries –, making it easy to quickly get the solar energy system up and running. With the monitoring tools, users can call up and view the system’s performance online at any time.

Bosch launches the innovative software e.Designer enabling the intelligent connection of PV system with inverters and storage systems: the intuitive program allows users to configure and calculate PV systems with Bosch inverters and battery storage systems as well as thermal storage solutions such as heat pumps in an optimum way. Based on an extensive module and location data base the e.Designer offers the possibility of an exact economics calculation.

At Intersolar, Bosch will also be demonstrating the networking of distributed energy production facilities with electromobility infrastructures. A smart combination of solar energy systems and charging stations for e-vehicles allows users to optimize consumption of the energy generated and to cut costs.

Smart wireless thermostat with intuitive touch control
The Bosch-owned brand Junkers is showcasing the Junkers Control, a black glass thermostat in a modern design with intuitive touch control. It allows users to set their desired room temperature at home easily and conveniently via smartphone. The thermostat is wi-fi-enabled, simple to install, and even factors in weather data sourced from the internet when making adjustments. Its away mode recognizes when occupants have left the house and automatically switches the heating to energy-saving mode. The Junkers Control is compatible with many Junkers gas devices.

Junkers will also be presenting the Supraeco SAO-2, a web-enabled air/water heat pump. The IP gateway necessary for the pump to communicate with the internet is integrated as standard. This means the heat pump will be quick to install and operate easily and conveniently via smartphone or tablet. It can also actively cool rooms down. With its inverter technology, the heat pump not only automatically adjusts to the current heating requirement, it is also 11 percent more efficient than its predecessor. The unit has an output of 8 kilowatts and can, for example, provide up to 4.2 kilowatt hours of heat energy using 1 kilowatt hour of electricity at an outdoor temperature of 2 degrees Celsius. Owing to its reduced electricity consumption, the system produces less CO2, although the exact ratios depend on the energy mix used to operate the pump.

Efficient CHP plants are good for the environment and cut costs
Environmentally friendly power generated by decentralized facilities is the key to improving energy efficiency. Bosch is presenting efficient CHP plants that cut costs and help protect the environment: they perform just as well as separate electricity and heat generation facilities while consuming less gas. This also cuts CO2 emissions. Bosch’s compressed-air CHP plant helps reduce production costs for compressed air. The Master Energy Control (MEC) Remote by Bosch makes it possible to update the software, carry out remote diagnostics, and resolve malfunctions for CHP plants without a technician having to be on site.

Modular storage solutions for “green homes” and industry
Bosch’s modular storage solutions optimize energy consumption for energy-efficient residential properties by combining solar energy systems and CHP plants. The company designs, develops, and builds storage units that are customized to each particular application. The units come in a range of sizes, all the way up to megawatt-hour systems. In commercial sectors, these systems also include applications for providing grid services. Bosch tailors the storage solution’s capacity and electronics precisely to the customer’s requirements; for example, designing a system for the energy network of a housing complex. The smart control of the battery system makes it possible to load and discharge the battery particularly efficiently, thereby extending the life of the battery and making the system more economical to operate.
