For a long time I have had this thought in mind. Why can’t washing machines have 2 water inlets, separate for Hot and Cold since so many users now have Solar Heaters at home.
How it would help:
- Reduction in energy costs when heated wash is used.
- Most washing soaps are designed to work in room temperature, and this would allow the machine to manipulate and chose a water temperature.
- Definitely green.
For the sake of redundancy, the heater part should remain. After all, we do not really get the sun shining all the time.
