Heating residential buildings with thermal heat pumps


New gas adsorption heating device for single- and multi-family homes

For a long time, thermal heat pumps were generally considered too large to cover the relatively low heating requirements of single- and multi-family homes efficiently. Newly developed gas adsorption heating devices can now change that.

They have been developed specifically for this application. The BINE-Projektinfo brochure “Heating with gas adsorption heat pumps“ (03/2015) presents one of the new devices. This combines condensing boiler technology with a zeolite/water-based thermal heat pump module.

The device consists of two modules: the thermal heat pump module covers the base load for the building heating. The necessary drive heat is provided by a gas condensing module. This also covers the peak heating requirement on very cold days.

Compared with an electric heat pump, the new concept requires significantly less environmental heat. Borehole heat exchangers, ground collectors and geothermal baskets as well as solar thermal energy can be used as heat sources. An up to 40% greater annual utilisation rate can be achieved relative to pure gas condensing boilers.

The gas-adsorption heating device has been developed by the Viessmann company from Allendorf, Germany. In the subsequent field tests, plant operators and heating installers confirmed their excellent experience with the devices. The operators particularly highlighted the low noise emissions and intuitive operation. The effort required for the installation and commissioning is no greater than for conventional heating systems.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
