Aventa is participating in a new EU project – solar collectors in combination with district heating

A new Horizon 2020 project, RELaTED, that is focusing on heat delivery from solar collectors into district heating systems has been launched. The innovative aspect of the project is that the solar collectors are decentralized. Heat is produced where it is to be used and not in solar parks which require large land areas.

District heating (DH) systems are one of the most energy efficient heating systems in urban environments, with proven reliability within many decades already. DH systems are also  identified as a key to achieve the de-carbonization of heating energy in European Cities. Renewable and waste heat sources are foreseen at the same time as de-carbonized heat sources and the way to guarantee competitive energy costs with limited influence of fossil fuel supply price volatility. 

Traditionally, district heating plants are hierarchically organized with central energy production facilities delivering heat to a variety of distributed consumption locations. RELaTED will introduce an new concept in which a network of low-temperature energy sources / technologies (solar collectors, heat pumps) can be incorporated into a low-temperature district heating system. The goal is to reduce operating costs associated with heat loss and to make the systems greener without major investment costs.

The RELaTED concept will be demonstrated in five different district heating networks, both new and existing, in Denmark, Estonia, Serbia and Spain. The strategy is in many ways the same as for electrical smart grids, where end customers are both consumers and manufacturers (plus customers).

9 different nations are engaged in RELaTED and the project will last until 2021.

Aventa approved as a supplier to UNHCR

Aventa has received approval as a supplier to the UN High Commissioner for Refugees, UNHCR. First delivery contract has already been signed and 80 stand-alone solar collectors will be sent to a refugee camp in Uganda during Q1 2018. The solar collectors will supply hot water for hygiene purposes.

Aventa offers a self-circulating heating system (thermosyphon) for tap water based on polymer collectors. The system operates automatically without the need for electricity, pumps and control equipment, and it has a favorable price. The fact that the solar panels are made in polymeric materials means that there is no danger of corrosion and the low weight makes them easy to handle.

Representatives from UNHCR visited Aventa and our production facility in early October, and there has been a thorough review of both the product and the manufacturing process. Approval of Aventa as supplier and Thermosyphon collectors as a suitable product came during November. UNHCR has now established a collaboration between Aventa and EDILSIDER S.p.A Modular Housing. EDILSIDER is a contracted supplier to UNHCR on small prefabricated modular houses for refugee camps.
