Abstract

Low grade heat from roofs and walls can be upgraded to useful temperatures by heat pumps. Even latent heat can be used. This report gives a survey of the possibilities to use these forms of heat in houses. Several types of heat pumps are described; working of heat absorbers is explained and cost aspects are discussed. Absorbers are less sensitive for shadows than solar collectors, which is a remarkable advantage in urban areas where high-rise building is employed. Application of solar absorbers is closely connected to heat pumps. Both absorber systems and heat pumps are so expensive that the costs are now prohibitive when gas is available, but this is due to small production series. Construction and materials make cheaper production possible when demand increases. (A.V.)
