thank you for the answer :)

I forgot that dishwashers rinse with hot water, no need for double entry.

At home it is much further from the solar balloon, I've already thought about the washing machine in summer, but my washing machine has only one entrance ...

All washing cycles are done with hot water on a dishwasher?

Sorry I do not know how this type of device works ... I've never had one in my life ... So it's a real technological leap for me who is preparing ...

That would mean that the dishwasher could only be connected to the ECS?

No, it means that it also heats the rinse water.

Donc ...

Can any dishwashers be connected to ecs only (solar in this case) without affecting its operation and performance?

Most dishwashers are connected to cold water. So you do what you want.

NB: for the LL (washing machine), the water volumes are much larger, but the rinsing is done with cold water (generally 2 or 3 rinses). If no special "box" (alfamix - at 200 euros, depreciation period: 1 century) or no dual entry machines, abstain or .... risk of a cold shower because the LL will have almost exhausted the CESI reserve! And of course, wasting hot water when rinsing if it is not free (normally cold rinsing water is replaced by hot water). So an increase in the bill and the financial / carbon footprint ... I tinkered with a system with a mixer and by-pass, but you have to stay on the side! We must also change habits: one machine on sunny days and not a "laundry day" - with 3 or 4 machines = empty CESI = cold shower! It's not insurmountable, but hey, you have to know.


On your remark regarding the use of a device to supply a washing machine with hot water but also with rainwater. no it does not take a century to amortize it. I am a self-employed person and I have developed an Obiwash.fr device. The savings can be 32 € / year for hot water and 39 € / year, i.e. a total of 71 € / year at 250 cycles / year 40, average French consumption. The device is automatic even when using a delayed start. At your disposal for more info. For info the Alfamix is ​​worth 300 € € with the delayed departure ...

The problem is solved !

On the occasion of a replacement, I opted for an LL with double entry (Bosch did, not significantly more expensive than the other models of the brand).

250 washes per year is still not bad. We are less than 100 ...

I haven't read all 15 pages...but I'm giving my feedback over more than 10 years

I can tell you that since 2012 my solar hot water has been supplying my dishwasher and my washing machine at 40 degrees (thanks to a mixer).
Simply plugged into the water supply of the appliance.
The only problem is I can no longer wash cold....but given the energy savings over the year I do without the 2 annual cold machines.

I just changed the LV during this same period but it was 15 years old so 4 with solar hot water, the electronics failed.

Same for my LV...it still works on solar DHW...RAS since 2011...

On the other hand, I have never taken the LL on it (laziness, forgetfulness...)... I note to do this during the winter!

Especially since I completed my solar ECS supplement in thermodynamics 2 years ago: water-pumping-filtration / transforming-a-solar-DHW-tank-into-thermodynamic-water-heater-with-a-small-swimming-pool-t17035.html

(Hey, this should interest you as a project)
