Combi boiler hot water shut off to tap

[ADurr]

Hi guys

got a aquaplus valliant combi boiler and need to stick some isolating valves on both hot and cold tap feeds in kitchen (boiler is on middle floor).

which valve can I isolate the boiler with so that there is minimal hot water loss from the system whilst I do the isolating valves?

Isolate the main stopcock, not the boiler (this would only isolate the hot), the stopcock will do both. No hot water loss anyway as it’s a combi boiler.

Nice use of pushfit connectors right near the boiler

The boiler is a storage combi. Tank might empty when stopcock is turned off... Try it.

If you're worried about losing hot water (which is a bit tight really) then turn cold feed off and use whatever hot water comes out for washing up or something, then do the work you propose.
