    today is the important day of the year where i bleed the radiators. like a medieval physician employed at the court of the boiler. i have a wadded rag of fabric and this special brass implement which i twist. i have to ensure the 4 humors of the central heating system are in balance: clear water, rusty water, methane, and some kind of fluming effluvium. i think the rusty water represents blood, but don't take my word for it, i'm not an expert. speak to a bearer of the crest of the hound of wales

    @jk well yes, but also the trick is to put the external thing somewhere like on the roof ¯\_(ツ)_/¯

    @jk @thomasfuchs I’m about to have one installed so I hope so. Word on the street is things have improved a lot over the last couple of years.

    On a side note, why would a heat pump remove the need to bleed your radiators? Most are still air-to-water as far as I know.

    @cablespaghetti @jk The only thing that makes sense to switch to in most places is using air to heat and cool. Heat waves and extreme humidity will get more frequent, so heating alone won’t be cutting it in most places.

    @cablespaghetti @jk “central air” as it’s called in the US has as an added benefit almost no maintenance except for swapping air filters and a quick once-a-year checkup on heat pump (that you also need for water-based heating with a heat pump)

    @jk my least favourite thing about bleeding radiators is that there's a knack to doing it without soaking the floor or your sleeve, and every year I've forgotten it, and every year, the point at which I get the hang of the technique again is just when I've run out of radiators that need bleeding.
