Book release: Heating with Renewable Energy

The new book “Heating with Renewable Energy” provides detailed discussions for each type of renewable energy heat source. (Picture: Appropriate Designs)

Heating with Renewable Energy is a new textbook written by John Siegenthaler, and published by Cengage Learning. This 850 page full colour text shows how to design and construct practical systems that supply space heating and domestic hot water using renewable energy heat sources.


Millions for new heat storage

A new research project by the European Union is funding the development of innovative heat storage systems with more than 4.7 million euros. The technologies are intended to help store solar heat generated during the summer inexpensively for use in the winter.


New buildings in Germany have to use renewable energy for heating

On the first of January, strict rules for construction came into effect in Germany. Heating new buildings without using renewable energy is nearly impossible. Oil heaters will probably not be used anymore in new single family houses.


Solar heat pump achieves energy savings of up to 30%

As part of a research project, the Swiss Institute for Solar Technology SPF in Rapperswil has developed a new solar heat pump heating system that achieves energy savings of up to 30%. At the same time, the system ensures that almost no errors can occur during installation.


Residential area uses solar thermal and district heating

A city district in the German town Freiburg will use a solar thermal system for heating and hot water production. During periods with low solar irradiation, the buildings will be supplied with heat from a district heating system.


Scottish Solar Home: Adding value is not about adding subsidy

Both the solar thermal collectors and the PV panels are from the same supplier, Viridian Solar, and are designed to look nearly exactly the same. (Photo: Solar Kingdom Ltd)

A Scottish ultra-low carbon home won a prestigious Solar Award using a very uncommon solar installation. Ignoring some subsidies schemes, both PV and solar thermal panels are arranged in a quite unusual east-west-configuration.


Collectors last a long time

What happens to a collector when it is exposed to the elements day in and day out? Does it lose a significant amount of its performance over the years or might the frame even crumble at some point? Researchers did not find evidence for any of this. Modern, industrially manufactured collectors are resilient. And not just in the moderate climate of central Europe, but also under extreme conditions such as in tropical India.
