Bivalent heating installation with a heat pump and solar collectors for a residential building

Solar energy systems and heat pumps are two promising means of reducing the consumption of fossil energy resources and the cost of delivered energy for residential heating. The integration of these two installations presents a novel combined heating system, so-called bivalent system, operating more economically. The major objective of this paper was to analyze the possibility of construction and benefits of a bivalent system composed of a heat pump and solar collectors for heating and cooling residential buildings.
