whilst systems this dumb are indeed very common, things are steadily improving as people get
programmable room stats, TRVs, boiler managers, and even fancy linux-controlled home-autoation
systems. As eneergy prices rise the benefits of having a more flexible control system

I agree with your fundamental point that exactly how usefully your computers do or do not
contribute to house heating depends on the control system installed.

I believe central electric heating is rare in the US, because it's cheaper and more useful to put a separate electric heater in every room. In contrast, gas/coal/oil systems are centralized because it isn't practical to put a burner in every room. Or even a thermostat.

I've seen central electric (forced air is worth paying more for for many people), just not very much.

I don't know why that would differ between the UK and the US, though.

Central heating in towns and cities in the UK is pretty universally 
natural gas-based. Outlying regions might use oil-based heating, storage 
heaters, or stranger systems, and places with broken or very old central 
heating or bad insulation might choose to stick electrical heaters in some 
rooms. Pure house-wide electricity-based systems are unheard of (by me at 
least): even heating your water with electricity is an emergency fallback 
for when the gas or boiler goes out. (It's also pretty much a historical 
curiosity: in thirty years I've never seen a built-in electrical immersion 
heater used, but they're still widely fitted).
