Heating system with heat pump - has underground water store, solar cell, and heat pump

摘要

The system has an underground container (1) to collect water. The water is fed via a pump (4) and a rising pipe (5) to a solar cell (6), and returned via a down-pipe (7). The heated water is fed to the condenser (9) of the heat pump (10), and the cooled water is returned to the container. The container is located below the frost level, and may be fed with rain water from the house roof (3). Alternately, there may be two connected containers, and the solar cells may consist of hollow elements filling the complete roof.
