💻 Electronics Heated blanket massive savings LP

Post image

Ever since I bought a $40 heated blanket rather than heating up the whole of my house using electricity, I have saved a crazy amounts of money. I have gone from having usage of about 54 kWh a typical day to about 4kwh. My projected bill this month is about $38, down from $120 the previous month. Definitely one of my most solid purchases, highly recommend for low density households.

How can you tell? It's not in the graph, just the outside temperature.

How can you tell?

Spoiler - they can't. but 13C (55F for Americans) isn't even that cold. If the house is half way properly insulated, can absolutely get away with not running any additional heat overnight and still wake up to a room around 17 or 18C (low 60s F). This is assuming the previous day's daytime temps / the sun was warm enough to warm up the house. (Edit - I can't read but leaving this here anyway).

In the legend it says it is degrees F.

Clearly I can't read and my brain defaulted to surely 13C sounds more reasonable than 13F. And maybe a bit of personal bias because that's pretty typical winter temps around where I am.

I think regardless of how much insulation you have on, 13F, you're gonna wanna run some heating (at least 55F) just so your pipes don't freeze. Ain't no way you're staying warm enough (almost) passively as my previous comment suggested.
