Title: Permanent magnetism in heating system pumps
The Brötje company (Germany) developed a new technology that saves energy and money in electrical heating systems and so made a positive contribution to the environment. The key to the new technology is permanent magnetism of the circulation pumps of the gas-caloric devices. Energy consumption was reduced by 50%, which means that up to 260 kWh per furnace per year can be saved. This puts the pumps in energy efficiency class A. Furthermore, the long lifetime of the new circulation pumps means that they will outlive the furnace.
