Optimal Water Temperature for Dishwasher: Cold vs Hot in Different Living Situations

Hello

If the dishwasher, apart from connecting to cold water, has the option of connecting to the hot water, it is worth using it when you live in a block of flats and normally pay for hot water?
Does it only make sense in the case of houses where hot water is obtained, for example, from solar panels?

greetings

Is this dishwasher adapted to hot water, if not, it can damage the water jacket, many other things that are made of plastic, not resistant to high temperature

Since I am writing about a dishwasher, which I quote "... apart from connecting to cold water, it has the option of connecting to hot water ..." it means that it is adapted.
But it is not a specific model

If we only have access to hot water, which is cheaper than electric heating, then for economic and sometimes ecological reasons, connecting a dishwasher or washing machine to hot water is even advisable (at current energy prices).
It is known that hot water in the installation can have different temperatures, so install a thermostatic mixing valve, connect the valve to cold and hot water and the outlet to the washing machine, dishwasher, set the valve e.g. 40 ° and we can wash at 40 ° without fear of destroying delicate laundry, also the electronic programmer in modern devices of this type should not freeze and show a temperature error, and the washing or washing process will be shortened by the heating time.
For me, it looks like this in the summer I have hot water from the solar collector, and in the winter from the heat exchanger at the outlet of the fireplace exhaust, so it would be a sin not to use the ecologically obtained excess heat, in the bathroom I have a 15-year-old MATURA washing machine connected by a thermostatic mixing valve and A trained wife, if she washes, for example: 30 °, 40 °, 60 ° or 90 °, then the valve sets this temperature (of course, the washing machine never warms up 90 ° in the installation) and immediately after drawing hot water, she switches the valve to cold water for rinsing.
It sometimes happens that he forgets to switch to the cold one and after two washes there is no warm one, but the laundry was washed super clean.
Therefore, in the future, I think to replace the washing machine with hot water intake, let it mix itself, because my wife sometimes forgets about the valves.
I do not have a dishwasher yet, in the future, if I would also purchase a hot water connection, it is a pity that the offer of these devices with the possibility of connecting to hot water is poor in such a large supermarket as MEDIA & MARKT, I was not offered any washing machines with this system, even in online stores are rare .

In the case of a dishwasher, as long as the water is not more than 60 degrees, no mixing valves are needed, you can immediately connect under the warm one. It is worth having well-insulated pipes, because with the amount of water consumed by the dishwasher at once (3-5 L), hot water will not "reach" and we will pay for it.
