I am equipped with a gas boiler in my kitchen, but in my bathroom, to have hot water, I lose between 5 to 6 liters of water with each use. How to cure it? I live in an old building on the 10th floor and 10 meters separates my boiler from my bathroom.

There is not much more than moving your water heater to get as close to your point of consumption as possible. Thus the length of the pipes necessary for the space to be traveled will be reduced and the hot water will arrive faster. You can also change your water heater for a micro-storage gas model providing a few liters of storage in an independent mini-balloon that ensures very fast hot water availability at the tap outlet.
