Abstract [sv]

The houses we build today are very energy efficient and we have minimized the demand of energy for heating. But tap water can still consume 50% of the total energy cost. Mandatory laws and regulations of today forces us to look over our usage of energy.

In this report I compare my own prototype with some of the existing systems for recycling energy in wastewater. All existing systems for recycling energy in wastewater only let the new tap water meet the wastewater in a simple heat-exchanger. This way most of the energy leaves the building with a low grade of recycling.

My experiment diverse significantly from the existing systems. In my prototype I allow the wastewater to stay for some time in the building while I recycle the energy in it. A number of tests was made in an existing building with eight flats. Using a heat pump the tank with wastewater was forced to as low temperature as possible without reaching the freezing point.
