I need to turn mains water off for a bit, will it affect ASHP?

Hi
I want to fix a dripping tap, so Ill need to turn the mains off. Will this affect the ASHP plumbing? All my heating (radiators etc) is controlled by the ASHP.
I think its safe to turn off the water, but thought Id check first. 
Thanks

No problem; an ASHP draws no water from the mains.  Somewhere there will be a valve that you can turn on to add water to the heating system but as it is a dripping tap and not a dripping radiator then you won't need to use that.

Check to see if there is an isolating valve/tap on the hot water cylinder for DHW draw-off. I used to have a valve with a big red handle on my old hot water tank. It would only shut of water entering the tank, but it was enough to fix a leaking tap.

While you are fixing your tap, have a think about fitting isolation valves to the pipework under the sink (or bath) on both hot and cold feeds.

Thanks FreeBear. Ill have a look and see if there are further isolating valves under the sink.

I do have a big red isolator valve for the ASHP stuff. I have a few actually. Ill need to go down there to see. Thanks
