It takes large thermal storage tanks to heat apartment buildings highly efficiently. To install them, they have to fit through standard door openings in existing buildings. The BINE Projektinfo 3/2017 “Large storage tank developed for small spaces” introduces a model that makes this easy. It consists of multiple modules and has lower heat losses than the cascade storage systems previously used.
The thermal storage tank is not fully assembled until it reaches the boiler room
The individual oval steel modules of the storage tank are mounted close to each other on rails during the installation and are then pushed together. They have a volume of 1350 litres each. The pipe connections between the individual modules are in the vessel.
“UniSto”, as the new storage tank is called, offers the same volume but a smaller and fully insulated surface, which reduces heat loss. It is insulated with hard shells of expanded polystyrene. Vacuum insulation panels (VIP) can be fitted in the cavities within the hard shells if required.
The storage tank has already been trialled in several field tests. For example, a Swiss-German energy supply company installed a prototype in a nursing home in Rheinfelden.
A heat-led, gas-fired combined heat and power plant and a gas condensing boiler for peak loads meet all heating requirements of the 74 residential units and partially cover the electricity demand.
The storage tank is hydraulically integrated in the system so that it stores the waste heat from the combined heat and power system and can make it available both for space heating and heating drinking water.
Research in the “UniSto” project was performed by an industrial consortium involving the Institute for Thermodynamics and Thermal Engineering (University of Stuttgart) and Consolar Solare Energiesysteme GmbH, among others.

About BINE Information Service
Energy research for practical applications
The BINE Information Service reports on energy research topics, such as new materials, systems and components, as well as innovative concepts and methods. The knowledge gained is incorporated into the implementation of new technologies in practice, because first-rate information provides a basis for pioneering decisions, whether in the planning of energy-optimised buildings, increasing the efficiency of industrial processes, or integrating renewable energy sources into existing systems.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
