Slow hot water

You probably have and airlock in your hot water pipework, hopefully it may disipate with running the hot water tap or after a drive to site?

Hi , thanks for that, it's been a month now so not sure about airlock but I've improved it slightly by adjusting the pressure regulator.

I am not familiar with the Whale system but have in the past experienced problems with the hot side of the water system which I had always put down to an air lock somewhere in the system. One way I found of clearing this was to switch everything off and then empty the tank again and then refill. For some reason it seemed to work on the second fill. Might be worth a try.

Lime scale build up in hot water pipes if you have been re filling with hard water - same as lime scale in a kettle?
