Bosch Thermotechnik invests in climate protection

Development cooperation to achieve breakthrough for combined heat and power generation in the domestic sector

Development cooperation to achieve breakthrough for combined heat and power generation in the domestic sector
Agreement signed with Enatec, MTS and Rinnai

Bosch Thermotechnik, Enatec micro-cogen (Netherlands), Merloni TermoSanitari-MTS (Italy) and Rinnai (Japan) plan to develop an electricity-generating heater based on Stirling technology. The four companies have signed a cooperation agreement to make this form of combined heat and power generation (CHP) marketable.

Enatec micro-cogen, Rinnai and Infinia have already developed a Stirling module - based on the Infinia free piston Stirling design - that has been specifically adapted for use in small CHP-systems. This first-generation module will be produced by Rinnai.

Under the cooperation agreement Bosch Thermotechnik and MTS plan to install and test over 1,000 gas-fired first-generation devices in the context of a Europe-wide field test between 2008 and 2010. This would be the world's largest Stirling technology field test conducted to date.

Building on the results of the field test, the four cooperation partners plan to develop a second generation gas-fired Stirling heater. Rinnai aims to launch a system specifically adapted to the Japanese market, while Bosch Thermotechnik and MTS will focus on adapting the overall system to the requirements of the European market. The second-generation Stirling heater is expected to be mass produced by Rinnai from 2011. The system would be marketed separately by Bosch Thermotechnik, MTS and Rinnai.

Stirling heaters generate electric energy and heat exactly where they are needed, so that no energy is lost during transport. Thanks to the decentralised and highly efficient parallel generation of electricity and heat, Stirling heaters can achieve a high overall efficiency of over 90 percent.

Consisting of a Stirling engine, a burner, a fan, a heat cell and a gas valve, the electricity-generating Stirling heating system is very environmentally friendly as the heat released in the electricity generating process is almost entirely used for space and hot water heating.

The basic principle underlying the Stirling engine was first patented by the Reverend Robert Stirling in Scotland in 1816. The engine makes use of the property of gases to expand strongly when heated and conversely to contract as they cool. Two pistons run in a hermetically sealed cylinder filled with an operating gas. One end of the cylinder is heated by a gas burner while the other is cooled by water from the heating circuit in the building. One of the two pistons – known as the displacer piston – alternately displaces the operating gas from the cold side to the hot side and vice versa. This alternation between heating and cooling produces a pressure difference which moves the second piston - the power piston. The power piston forms part of a generator which converts the piston movement into electricity.
