OK bathroom radiator removed, only temporarily and as it's removed there's no complete circuit in the system.
If I run the boiler/heating like this for a couple of nights how detrimental is this on the boiler? (Will it wear the pump sending back water rather than circulating?
(Yes it gets cold in my house circa 8pm! I am a full member Yorkshireman however I've softened abit living towards Lancs way.
You'll be reyt. It'll work fine.
Assuming the radiators aren't all in series, shouldn't have any effect - in my perfectly amateur opinion!
So settle back and relax in your fluffy dressing gown and slippers and RELAX!
It'll be fine. Isolate & then I always unscrew the thermostatic valve as a precaution...
It'l be fine
I presume you mean all the other rads have thermostatic valves?
Just remove one of the thermostat caps from one of those other radiator valves - then that rad is open all the time and makes a circuit.
There is a crossover valve at the boiler in case all the thermostat valves are closed. You should be fine. The pump is not sentient and won't even notice.

Might do if it's a smart pump, it'll ramp down and save energy, if it's not it'll still be fine, centrifugal pumps work fine with a closed valve, displacement pumps however blow up. Yours will be the former, the latter are used to provide pressure in hydraulic systems that hold the roofs of coal mines up.
Sentient? Please explain not totally savvy with plumbing speak.
Is it an old single pipe system or do you have separate flow and return?

He means that the pump is not aware of its own existence. And so is incabable of worrying about hora's bathroom radiator 🙂
Commercial pumps can be, ours have clever software that detects demand based on power consumption and speed up and down dependant on how many valves are open. Even our small circulator have this capability.
Single pipe, double pipe system.... the pump will care less. With either pipe set up the flow is not dependant upon the rad being in place to circulate the water.
Radiators are connected to a two pipe system by teeing into the flow and return for each pipe. (not by interrupting them. For a single pipe system the rad is teed into the single pipe and again does not interrupt the pipe work. So, by removing a rad you simply cause the water to bypass that location.
No problem.
Simply turn off the valves to the rad, drain it and remove. If there is a TRV on it, you will need a "Decorators" cap for that valve just to be sure it doesn't open should the valve fail. These come with all valves when new. If you don't have one, a 3/4" or 1/2" female cap will seal off the valve opening depending what valve it is just to be safe.
