Shut that door!!

We had an old friend visit yesterday @ 6PM and we rapidly fell into debate, solving world issues and the like. But after a couple of hours I glanced at the indoor temperature and wondered for a moment why it was low'ish. With 3 adults, rather than the usual 2, we normally do not need any supplementary heating.

After another hour or so I started to wonder why the temperature had not climbed above 19.9°C, despite about 1.2kW of electric heating. I looked in the hall and found both the front door and the porch door were open. Not wide, just 1 and 2 inches respectively, but enough to pretty much bugger up the whole air-tight-Passivhaus principle :)
