Can my 'Grundfos' central heating pump be left ON - for any long period of time? And if so, for how long??

Any help would be greatly appreciated!
 
It would probably be happy to run 24hrs every day but it's lifetime would likely be reduced and worst of all it would be a waste of energy.
 
If your system is working ok then it can safely left on 24/7.rather srang question.Is system ok?
 
Apologies, let me explain...

I live in an old building (1 of 9 flats); where we share a communal heating / water system with a single boiler & tank.

The heating is permanently switched on, and I merely have to turn the thermostat on each radiator when I want them to heat up. With dated radiators, it's never been great; but recently they stopped working altogether!

For some reason, my flat is one of only 2 that have their own pumps - which is strange (I didn't even realise I had one). Anyway, a local plumber recommended a new one to circulate the water better and fitted a 'Grundfos Multihead G'. The old one mustn't have been working.

I don't have a thermostat on on the wall, so each time I want the pump to work (more often than not), I have to flick the mains switch.

Hence why I'm slightly concerned about how long I should have it switched on??
 
Have you considered a programmable thermostat to control your pump?
 
Yes, I've considered a thermostat; but my property is rented, and typically the Landlord is reluctant to spend any more money!
 
As a tenant, I don't think you should need to worry about how long a pump lasts (could run for decades). If it breaks, as part of the central heating, it should be down to the building's managing agents to fix. They usually charge a fortune for the heating anyway. It's common to see flats with communal heating where tenants just open windows if they are too warm in the winter! If you are the only one to turn a radiator down, guess where the sludge ends up...
