Remember, last August, we replaced our old oil-fired boiler by a beautiful quite new gas boiler.
The tank with fuel oil was in a premises inside the house, and it was thus emptied. Claire and Momo decided to use this small room to put the reserves and a freezer : so far, they had managed with the tiny freezer department over the refrigerator, but it was a little bit small. We need a complete floor for us, and our humans had only one floor for them.
Momo thus took his tools, and he isolated walls and ground of the place. He made two openings in the door to put aeration railings because there are no windows, laid a stone floor, then repaints the door, the walls and the heating pipe.
