Product catalog summary

Introduction
Buderus, part of Bosch Thermotechnology Ltd., has been a leader in the European heating industry for over 275 years. The company offers solar thermal systems for large-scale commercial installations, providing sustainable water and space heating solutions. Their solar products are compatible with commercial boilers and control systems, ensuring efficient energy solutions for various applications such as industrial projects, office blocks, schools, sports centers, hotels, and hospitals.

Solar Technology Explained
Solar thermal systems capture solar energy for hot water and space heating. Buderus offers flat panel and evacuated tube collectors. Evacuated tube collectors are more efficient in colder conditions due to better insulation, while flat plate collectors are suitable for limited space installations. Solar energy can meet nearly 100% of domestic hot water heating demands from April to September, with conventional systems supplementing during other months.

System Integration and Benefits
Buderus systems can integrate into existing heating systems and are eligible for tax relief under the Carbon Trust's ECA scheme. Solar installations reduce reliance on fossil fuels, lower carbon footprints, and demonstrate environmental responsibility. A collector area of 6m² can prevent the release of up to 1000kg of CO2 annually.

Product Overview
Buderus offers SKR6 and SKR12 evacuated tube collectors, efficient even in low sunlight. These collectors use a vacuum flask principle for insulation and are easy to install. The SKS 4.0 flat plate collectors feature high-performance technology with a dual meander copper absorber and are resistant to weather and corrosion.

Installation and Siting
Solar panels should ideally be south-facing with a pitch of 20-60 degrees. Buderus provides site visits for installation planning. Collectors can be installed on roofs, in-roof, or mounted on frames for flat roofs or walls. The system size depends on whether it provides hot water, space heating support, or swimming pool heating.

Conclusion
Buderus' solar thermal systems offer reliable, efficient, and environmentally friendly solutions for commercial heating needs. With over 30 years of experience, Buderus provides comprehensive support and high-quality products for long-term performance and energy savings.

Specifications

SKS 4.0 Collectors: Available in portrait and landscape orientations, with a collector area of 2.37 m² and an aperture area of 2.1 m². They feature a high absorption level of 95±2% and low emissions of 5±2%. Efficiency is noted at 85.1%, with a stagnation temperature of 204°C and a maximum operating pressure of 10 bar.
SKN (Lifestyle) Collectors: Available in portrait and landscape, with a slightly larger aperture area of 2.25 m². They offer a favorable price-performance ratio, with an efficiency of 77% and a stagnation temperature of 188°C.

Features

Both models offer easy installation options on flat roofs, within roofs, or on top of roof tiles.
SKS 4.0 collectors utilize dual meander technology for optimal heat transfer and are hermetically sealed with inert noble gas to prevent thermal losses.
SKN collectors are noted for their robust fiberglass framework and energy-saving manufacturing processes.

Integration and Controls

Solar technology explained Why solar? Why now? Solar is one of the fastest growing ‘renewable’ technologies, and when you compare the amount of solar energy available during the year, with the remaining fossil fuel reserves that the earth has to offer, it is easy to see why the uptake of solar thermal systems has been so rapid. Following the initial investment solar is effectively a continuous source of free energy that can be put to use to provide hot water and space heating. With the right controls your boiler would only come into use when there is not enough solar energy available to meet...
