    When you can no longer buy a machine which takes a hot water feed? Dream on!

      Thinking on though, fibres from washing machine wasted water could play havoc with plumbing and would encourage bacterial growth.

        Our washing machine is ten years old (Bosch) and has never had a hot water feed. The wash process is much more efficient with a cold fill.

          It is doable and worth doing but there are practical challenges [in reusing waste water] that are not immediately obvious.

          Thankfully we have a plentiful supply of water here in Co. Durham thanks to Kielder water.

            Not only that but the dead leg on most hot water supplies probably prevents much water that is actually hot reaching the machine. Also, the machine only heats the water it really needs. What puzzles me though is the "eco" setting takes so much longer than the standard yet they claim it saves energy. My Bosch dishwasher also takes half the time and gets the dishes cleaner if I choose the non-eco setting.

              A longer cycle at lower temperature perhaps?

                Newton's law of cooling applies:

                Can be mitigated to a degree (intentional pun) but the second law of thermodynamics will always conquer.

                  Reference to the user manual for the washing machine reveals that the eco mode does indeed lower the temperature. Presumably that saves more energy than running the motor for twice as long!

                    I think I'll take my double dewar washing machine onto Dragon's Den. Minimal heat loss, but getting the clothes in and out is, as yet, a bit of a struggle. Early days.
