District heating plant | 4,875 sqm | 3,400 kW_th | 1998–2000

Before the solar heating plant the supply of heat was straw as the main source, supplied by pellets and a little oil in the peak winter load.
The plant was initiated to be able to stop the straw boiler at summer time and to use the heat storage in winter to reduce the demand for oil.

The new in this project is to demonstrate how solar heat and CHP can complement each other based on market prices, so the use of natural gas and thereby the CO₂-emission reduces. The 8000 m² are expected to produce 4,000 MWh annually which is 10 % of the total heat production.

The decision to build the CSTS was taken in the early 90's by the Danish Teachers Organisation who also owns the place today.
The CSTS is only used for producing hot tap water. But the roof could easily include double square meters of panels. By that the CSTS could also substitute the natural gas consumption for space heating in spring and autumn.

The CSTS is used only for domestic hot water heating. In the beginning the laundry machines in local common laundry facility also were connected to the domestic hot water system. But the machine supplier has recommended the association to disconnect that because there were no savings they said. (This is however not proved officially).

The project has been a really innovative project, precenting the following:
· new control mode in the form of variable flows
· test of two new types of heat storages
· being a place where a number of solutions for panel types, storage types etc. are presented

District heating plant | 2,500 sqm | 1,750 kW_th | 2002

Two villages on Samsø established a work group to investigate the possibilities for district heating. They evaluated that the power company NRGi should carry through the project because they already had experience from another project.
The plant is operated on commercial conditions. The solar energy is supported by a biomass boiler. The plant supersedes the usage of oil in the 185 households.

The solar heating plant was established as a R&D project within a Government programme to develop solar heating plants for district heating.
The solar heating plant is groundmounted at a plot of wasteland, situated 300 meters from the district heating plant.
At the time of construction the plant was by far the largest plant in Denmark.

The tenants initiated the installation of the CSTS and the motivator was the board of the association. The CSTS consist of flat plate collector in 2-part orientation (half west, half east). The solar thermal system was made as a demonstration project and consequently the price of the plant reflects this issue.
