What is an acceptable temperature inside a flat in winter?

Ah yes - much prefer my home-made microwavable barley bag- much softer heat and lovely smell often make them for friends and family, in all sorts of shapes, including shoulder and neck ones. When I waa a kid, we had ticking bags full of cherry stones- which we placed in the 'cavette' the small 'cave' with a brass door, of our big tiled wood-burner ('fed' from kitchen and with part in my brother's bedroom, and the main part in the lounge.

Well, I do stay at home and she knows that...

It would help... but I'm not even a tenant, I'm just a resident with a nasty cold and sore throat that won't go away.

Spoke to the ventilation guy, apart from showing us how to manually adjust the ventilation (something which the Vervaltung forgot to tell us about, among other things), he said there was nothing else that could be done. I keep loads of plants and we take long showers, together with laundry for two adults and a kid it makes for air humidity of 30% at the most.

We have thermostats so we can in theory control the temperature, but for example if I set the heating up in the kid's bedroom, the amount of hot water flowing from the distributing system under the kitchen floor brings up the temperature in that room. Which is pretty stupid since you produce heat when cooking. Hence, we have a couple of rooms where the temperature is too low, a couple where it's just ok and the kitchen where it's always too hot. Nothing to be done there either, plumber confirmed it.

This is a case of luxury apartment with loads of fancy features that don't work very well. Possibly they did 14 years ago but maintenance has been shaky since then.

put your air ex changer on a timer ,four times a day for 5 min. or turn it of altogether and get a humidity fire The whole system sounds like a lousy Engineering job Or better move back to CANADA ;-)

I've got to find myself one of those.

Does the heat with the barley last? I have cherry stone one, but it loses heat far too quickly for my liking.

It's minus 30 C minus , 40 C with wind shield ,its time to set the "T" stat to 19 C and close the door
