As it has already been shown in previous projects, the coupling of a solar thermal installation with abiomass boiler on a district heating network allows to reduce the wood consumption significantly. Theaim of the proposed project is to establish sizing rules as well as hydraulic and control schemes allowingto realize the solar/wood coupling without any negative impact on the operation of the wood-firedinstallation (increase of pollutant emissions, decrease of efficiency, etc.), and without any negativeimpact on the profitability of the district heating network. These sizing rules will help planners to optimallysize their installations. Finally, a comparative study will be conducted to compare a solar thermalsolution with a photovoltaic solution combined with a heat pump.
