20 terrace houses have been built in Sweden without traditional heating systems. Instead, the occupants rely on a heat exchanger and extremely effective insulation. The main sources of heat come from solar collectors on the roof, large south facing windows, exhaust air from the heat exchanger, heat radiating from electrical appliances and heat from the occupants themselves.
Construction costs are thought to be virtually unchanged as the extra costs of insulating the houses are offset by the lack of traditional heating system costs and reduced energy use.
