Jenni Energietechnik AG: Specialists in Solar Thermal Energy and Large-Scale Heat Storage
Jenni Energietechnik AG is a highly specialized Swiss company operating in the field of renewable energy and sustainable heating systems. Based in Oberburg bei Burgdorf, Switzerland, the company has established itself as a pioneer, particularly in solar thermal energy and the development and manufacturing of thermal energy storage (TES) solutions. With a history spanning over 45 years, Jenni Energietechnik AG focuses on providing integrated systems that enable a largely autonomous and fossil-fuel-free heat supply for both private and business customers.
The company's core philosophy centers on utilizing simple but crucial physical principles, mainly thermal stratification within large storage tanks, to maximize the efficiency and effectiveness of solar and wood-based heating systems. This approach allows for seasonal or long-term storage of heat, which is essential for ensuring reliable heating even during periods of low solar gain.
Core Business and Key Product Offerings
Jenni Energietechnik operates primarily as a system and component supplier and a project partner for complete energy solutions. The business is divided between private customers (single-family homes) and business customers (industrial plants, district heating networks, and multi-family houses).
1. Energy Storage Tanks: The Swiss Solartank
The flagship product and the heart of every Jenni heating solution is the Swiss Solartank. These are high-capacity heat and cold storage tanks designed to store energy cost-effectively in the form of hot water.
Product Scope: The Swiss Solartank is available in a vast range of sizes, from small-scale units of 300 liters for individual homes up to massive, large-volume tanks of 320,000 liters for major commercial and municipal projects, such as district heating systems.
Technology: These tanks are engineered to maintain thermal stratification, meaning layers of water at different temperatures are kept separate. This maximizes efficiency by ensuring the immediate availability of the hottest water for heating or domestic use, while maintaining a cooler section for collecting energy.
Applications: They serve as the central distributor and buffer in the entire energy system, integrating inputs from various sources (solar thermal, wood heating, heat recovery) and supplying outputs to heating circuits and hot water supply.
2. Solar Thermal Systems
Jenni Energietechnik is a renowned specialist in thermal solar systems, which are used to convert sunlight directly into heat for hot water and space heating.
Solutions: They offer complete solar thermal installations, ranging from systems suitable for single-family homes to large-scale collector fields used in heating networks.
Component Supply: The company supplies the necessary components, including high-performance solar collectors.
The Energy Roof: A specialized offering involves delivering the complete energy roof system directly to the project site by crane, streamlining the installation process for maximum efficiency.
3. Wood Heating Systems
The company strongly promotes the use of wood as a renewable, regional, and ecological heating source, supplying various wood-fired systems.
Log Wood, Wood Chip, and Pellet Boilers: Jenni is a distributor and integrator of heating systems from manufacturers like KWB, offering boilers designed for different forms of wood fuel, including pellet, log, and wood-chip heating systems. These units are suitable for varying project sizes, from family homes to large commercial buildings.
Water-Bearing Fireplaces: For residential applications, they offer water-bearing fireplaces that contribute to the central heating system while providing the ambiance of a traditional stove.
4. Control Systems and Energy Management
To ensure the optimal interaction of the various components?solar thermal collectors, wood boilers, and the Solartank?Jenni develops and supplies the necessary control systems.
Complexity: The offerings range from simple solar controls for basic installations to complex, networked control systems essential for managing large, intricate energy ecosystems.
Infrastructure: They also produce and install the required switch cabinets for both local and extensive district heating networks.
Services and Expertise
Beyond manufacturing and component supply, Jenni Energietechnik AG acts as a comprehensive consultancy and project management partner for its clients.
Project Development and Installation
The company guides projects through a structured, four-step process, often working closely with local partner installers:
Preliminary Quote: Initial assessment and costing.
Consultation: In-depth, on-site consultation to develop a concept specifically tailored to the customer's needs and structure, followed by a detailed quote.
Installation: Execution of the installation by a network of local partner installers.
Instruction and Quality Control: Final commissioning of the system by Jenni experts, including detailed operational instruction to the client to ensure long-term, high-quality performance.
System Integration and Consulting
Jenni Energietechnik?s long experience translates into significant expertise in system integration, particularly concerning renewable thermal energy projects. Their services extend to:
Renewable Energy Consulting: Advising clients on the best mix of renewable technologies for their specific energy profile.
Energy Management Consulting: Optimizing energy use and flow within industrial or large residential systems.
Solar Energy Consulting: Specialized advice on maximizing solar gain and system size.
Waste Heat Recovery Consulting: Integrating systems to capture and store waste heat from industrial processes into the Solartanks.
Engineering Services: Providing electrical engineering and electronic consulting related to their advanced control and monitoring systems.
Noteworthy Achievements
The company is historically significant for its successful execution of ambitious, fully renewable heating concepts. This includes the development and construction of solar houses, such as the building of the first entirely solar-heated multi-family house in Switzerland in 2005, which demonstrated the feasibility of achieving high levels of heat autonomy (often over 50%, with some achieving 100% solar coverage) using their integrated systems. This focus on deep solar coverage and self-sufficiency underscores Jenni Energietechnik AG's commitment to pushing the boundaries of sustainable and independent energy solutions.
