Are your rads like really shit / underspecified? Or does the boiler not have the juice to do it?
At a 60deg flow temp we can get our really shitty drafty / leaky combined back room and extension up to temp (19-20) in a couple of hours with a 30kw boiler and two double panel 2500mm modern rads. We are not end of terrace though.
Suspect it's a combination of under-specced (but nice looking) radiators, high ceilings, massive heat sink of non-insulated end of terrace wall and cheapo, ill fitting double glazing.
Living room has a couple of these. They're about 750mm
How big is the room these rads are in? The rad looks tiny, and won't hold a candle to a bog standard double-panel double-convector type 22 rad of equivalent size.
Worth ditching for suitable rads, for an immediate boost in efficiency.
