Apparently less than 10 degrees can be dangerous to older people, especially if they are recovering from something, and as someone who has lived with an open fire in the NE of Scotland I can tell you only heating bits of the house is unfortunately a false economy. We now have the fire on trickle much of the winter(it doesn't burn more fuel). It took 3 days to get the rest of the house back to an ok temp after that 26 hr powercut last November.
I'd check supplies of fuel before you even think about going for an open fire. Not sure where you live but coal in the UK doubled in price at the start of September and apparently won't be sold as of next April, only the smokeless shite which ime won't burn on an open fire til the fecking thing is roaring. We've had to go over to peat, that's £9 a bag and we're mixing peat, coal(already bought) and wood and just hoping something 'good' will happen on the coal price front
Yes...I meant 5 degrees outside.
The octogenarians wont be cold. The house is actually massively insulated. My dad put in triple insulation after the bitter winters in 2010 and 2011. The windows are double glazed too so once some heat builds up the place does hold heat well. But we wont be running the heat to reach 23 degrees like other winters.
The fire would be timber only...ig we go down that route. I am hoping some really good electric heaters will be a better option. My brother picked up 2 wall electric heaters to check them out. He has no central heating. But has triple glazing and the entire house is massively insulated. He didnt have to run more than one heater last winter. So I will try out one of those. If we dont attach it to the wall we can move it around.
We won't be cold....we just wont have the heating on all the time.
I've worn my thermal leggings for the past 2 days under a dress. They're really cozy. I'm pretty sure we will manage. Once we keep the rooms the octogenarians are in warm it'll be alright.
