We live in a semi isolated rural location at 1000ft elevation, private gravity fed water supply so no issue with water supply. House is heated with a wood burner with supplementary electric heaters & electric cooker.
Weather was of course windy then snow & freezing temps.
We didn't notice too much difference in keeping warm, a bit more in the bedrooms would've been nice but not a biggy. Water as mentioned wasn't an issue. Cooking was done on two trangias & a gas camping stove, worked well.
Light was provided by combination of UCO candle lanterns & torches.
There was no mobile signal for first couple of days. We had an analogue phone but it got dropped on day one and stopped working.
4G mobile signal was restored after a couple of days.
Things I've learnt -
The trangias were brilliant but the simple camping gas stove was really handy, particularly for that first brew in the morning.
I used an old car battery to recharge USB torches/phones/tablets but my solar panel couldn't recharge it sufficiently on the short overcast winter days. After three days we were using the cars to recharge USB devices.
We had two head torches but a head torch each would've been nice.
You can never have enough chocolate
Think that's it really, overall it was actually a pretty enjoyable few days. No internet & lots of boards games/charades/who am I?/wine & chocolate. Only thing missing was the zombie hordes
