Thanks for being kind, my logic was still bullshit ;-)
I was somehow wondering, if we lose that energy there anyway, without appliances failing, we could use that as heat source - which isn't too bad of an idea, but just fixing it and using an electric heater would be the actual solution.
I'm still fighting with a fever and headaches since my last business trip and I'm just not that bright at the moment.
And heavy painkillers lowers my inhibitions to just vomit out my thoughts without further reflection ;-)
