So they bought the château, tore down walls and floors, installed some floor heating but not in all rooms. First winter in they realised heating is too weak but they didn't ask the company to redo it as long they still had some warranty? And all 16 winters later they never had the idea to at least to use their wood and heat with burners?So the chimneys were not inspected before the burners were purchased? Well, of course not, that's silly. What do you bet that the chimneys are not fit to be used? Full of soot and what not, cracked stones and bricks, missing stones and bricks, etc. So stupid, it's unbelievable! Now there will be a pile of log burners joining the pile of toilets, sinks and bidets.
