Alpizar Castillo, J.J. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)The urge to reduce the dependence on natural gas for heating at the residential level has led to the deployment of different fossil fuel-free alternatives. In the Netherlands, two technologies are leading the transition: heat pumps, due to their high COP, and photovoltaic–thermal systems, due to their dual electric-thermal output. However,...journal article 2024
