Hello,
a quick question about washing machines that use warm or hot water.
We are debating whether to use the soft water from the rainwater cistern (I am very familiar with this topic professionally and know from numerous laboratory tests how high-quality, pure, and better rainwater is for washing—before any skeptics or critics comment on this *g*) which saves water, reduces repair and electricity costs due to scale-free water, is gentler on laundry and cleans better, or to draw warm water for the washing machine from the heating system’s warm water (geothermal heat pump).
Considering the costs and economics of consumption, does anyone have experience with which option is more worthwhile or if it is generally reasonable to put that load on the hot water system? I think, if so, washing should only be done during the day when warm water use for the household members is low.
It would be great if anyone has insights on this. The rainwater system itself is not in question, as it will be installed anyway and at least used for toilets and the garden, so only the additional pipe to the washing machine would have to be considered.

Ahnungslos16 May 2013 19:34I’d like to join this discussion as well. We have also decided to install a cistern but are still unsure whether to connect it to the house (only for toilet flushing – I also have some doubts about using it for the washing machine).
We have received a quote for the garden water connection and toilet flushing with a large pump (without the cistern – that is already included) for about 3000 EUR. Is this price reasonable, or financially sensible? Ecologically, it definitely makes sense.
What experiences have you had with this?
