Heat water in the oven - save energy
Energy saving tip: heat water in the oven.
It is often even recommended, e.g. when baking bread: put a bowl of water in the oven. And even cake, roast or pizza take the moisture not at all bad! You can make use of this and basically put water in a heat-insensitive bowl with the dough.
So you have the same warm water, to directly rinse some used things quickly, without straining the water heater, etc.!
