My central heating has individual thermostatically controlled valves on each
radiator.

I was given to understand that it was necessary to have one radiator without
a valve, near to a room thermostat so that the boiler will be turned off
when the room(s) reach the required temperature, to avoid very hot water
being cycled around just the pipework.

But in the (recently refurbished) flat that I have just moved in to, there
are thermostat controls on each rad and no room stat. Is this a correct
installation for the current state of the art?

The boiler is hidden away in a cupboard, so it can't be integrated into the
that as the cupboard will not be at 'room' temperature. I tend to have my
radiators set low as I don't like warm rooms and I wouldn't want to blow up
the boiler (not that it's my problem if it's the numpty landlord who's
responsible for yet another wrong installation [1])

It's a combi bolier if that makes any difference (an Ariston Combi A)
