Energy Savings for Solar Heating Systems in One Family Houses
Abstract
A high number of investigations on the thermal performance of solar heating systems, both under laboratory conditions and in practice, have been carried out. In spite of this, relatively few investigations have focused on energy savings of solar heating systems. This is remarkable, since most solar heating systems are installed with the aim to save energy. The main reason for the few investigations is that it is impossible directly to measure and very difficult to document the energy savings of solar heating systems in practice.
