Bad idea 10mm would be the minimum
Discuss Thinking about a 10mm hot tap feed in the Plumbing Jobs | The Job-board area at PlumbersForums.net
Last Plumber: "I would find out why it takes so long first though."
I would guess something like three litres of water have to be shifted and then there's the normal boiler heat-up time.
From a cold start probably about 90 seconds before the water is usefully hot.
This boiler has a 'Comfort' setting that claims to keep DHW hot and ready. I haven't used this setting yet but will give it a try. Do you know if 'Comfort' setting is going to be expensive to run?
Mind you, I'd still have the problem of shifting a load of cold water before the hot came through to the tap.

The hot tap has a healthy flow. I don't have a guage to measure water pressure but it seems very good.Comfort normally preheats primary water in some way. Depends on boiler. What is the flow rate on the hot water tap and on water main?
What is the pressure on the main?
