My mother is exactly like this with the heating too. It's forced and fake fuel poverty because I cover a lot of the fuel costs. The house is often freezing. Not only that her only idea of home maintaince is window ventilation and leaving the windows open all day. It's so so hard in the winter time. She sparing on the fuel costs. She won't even turn on the heating for an hour in the evenings.
Regarding other energy use, she has no comprehension. She has some idea and she wants to monitor my energy use but never never never never never hers. When a bill comes that she doesn't like, she will think it's me. She's not able to understand that first of all it's a shared house and two look at what she's is doing herself. She had the dryer on this morning to put her clothes that she's wearing for the day in there to warm for half an hour. This wasn't the first time she has done this. When 5 or 10 minutes would be more than enough. I considered getting her a towel warmer but she likely won't use it because it will be a new appliance and she will recognise heat from it and view it as a heater.
It's so so so hard. Yes, she's claiming most of the benefits that she can. I gave her a form a few months ago to applying for a home scheme to insulate the house but she won't fill it in.
I think with the form it's executive functioning. I now really think with the dryer, this is memory loss. I think she's putting in clothes and just forgetting. I always grew up with my mother having low use of the tumble dryer with a fear of the bill and now she is completely the opposite.
The next bill is going to be so much higher because of this new war and more rising costs and that will add so much but she she won't be able to understand that and she won't be able to adapt.
There is at least two laundry loads every week where she is washing at 60degrees when there is no need. Like her daily clothes and towel wash. A 40 wash would be more than enough.
Sometimes I would try and take a load of her but that's usually the household stuff like towels but that's always not possible. I have to plan around my work and around her sleep and get everything to align so that there is a load, I am there to do it and the time is appropriate.
I even bought the Dettol laundry cleanser but she refuses to use that.
Her comprehension is very very very bad.
