Central heating and TRVs

I would agree with matelodave. Most boilers, even very old ones can have a thermostat added.

I would however suggest a slightly better, but still cheap, wireless thermostat.

Plumbcentre do a re-branded Honeywell wireless thermostat for around £50. Which is apparently a much much better thermostat than the Salus brand. The Honeywells (which have a tiny bit more functionality go for £100+).

The best thing about a programmable stat is that if you want to increase or decrease the temperature temporarily it will revert back to it's original programme so there's no danger of leaving the heating on all night.

Some of the best ones have a holiday mode, which puts the heating to sleep whilst you are on holiday but turns it back on when you are due home so you don't come into a cold house after being away for a week or more.

I dont have a thermostat and I am concerned my boiler is running flat out for the entirety it is switched 'on'

My previous boiler, a Baxi new about 25 years ago, didn't have a room or wall thermostat but had a temperature control on it which measured the radiator water temperature as it was pumped through. Because of this the boiler wouldn't be heating the water constantly. I suspect yours is the same. The pump will be running but it will not be burning gas.
