Eco house - old building uses a washing machine with  separate warm  and cold water hook-ups. The warm water hook-up is directly connected to the solar warm-water supply. Thus the solar facility ensures free warm water with the help of the solar collectors, saving electricity used by the washing machine.

In the annual average, the solar facility has a solar covering degree with warm water of 90%.

Before the remediation, drinking water  used 97 m³ per year and after the remediation only 36 m ³ , which means a saving of 67%. In addition washing powder consumption is reduced by 50%. Water softener is no longer needed  because  rain water is a completely soft water in itself. In the toilets the urine-stone formation is substantially reduced. The life span of the washing machines is considerably increased because there is no more calcification. Electricity consumption is lowered. The solar facility and utilization of rain water complement each other marvellously and offer many advantages, including large monetary savings.
