But incandescent light bulbs are a terrible heat source from an efficiency perspective. You're losing an incredible amount from the power plant, to the transmission, and pretty much everything else. Once it arrives, yes, the energy gets converted nearly 100% to heat eventually, mostly in your proximity. But a heat pump or even gas heating is far more efficient if the goal is to get heat.

If you have electric heating anyway, it makes no difference. You’re right that a heat pump would be better, but for many people it isn’t an option.

If you read the article, the author is focusing on the scenario heating a person while sitting at their desk, not the entire room.
In those cases you could argue the methods he prescribes are more efficient, though not practical for times where you want to heat up a whole room or home.

Interesting, reminds me of several articles on this site.

Yeah, love that article. I'm slowly building a large foldaway 'kotatsu' coffee table using a mixture of ikea (ovraryd) and amazon/ebay parts (foldaway hairpin legs, centerpost, kotatsu heater).

yup. like my low flow toilet that i need to flush twice...
Not anymore, technology has improved a lot! Get this one (or variant on it): https://smile.amazon.com/gp/product/B001KAFKRM
I've owned it for 5 years and it's clogged only once (it happened in the first week of ownership) then never again.
And one time (in 5 years) I needed to flush it twice.

That one is bragging about a 3" valve. There are other toilets available now that have 4" valves.
Permies put out an article arguing for incandescent if your goal is light AND warmth: From https://richsoil.com/electric-heat.jsp - "This last one was the most important. A standard incandescent light bulb heats something to the point that it glows white hot. So I used this to heat myself and it doubled as a light source. And, I should point out that in a few months this light bulb will be banned by the US government. It is already banned in many countries. The comedy is that it is being banned to save energy. And yet, I think people can save far more energy by keeping it."
