Viessmann vitoden 111-w Combi serve?

[clemda1]

Hi guys,

I'm quoting for the installation of a Viessmann vitoden 111-w. For a 2 bathroom flat. Both with bath showers.
It's my understanding that this unit comes with a 46l storage vessel. However once the vessel depletes I've heard that's there's a valve that can be fitted to the hot water outlet to restrict the flow while it replenishes? Is this correct; if so can anyone advise on correct name of the valve, manufactures, and where I can pick one up? any handy tips on their installation would be appreciated as well.

Many thanks

I know the guy that came up with this. Cleaver bugger but now sadly unemployed.

Any chance you know where I can pick one up? Your link only seems to provide info.
thanks.

I thought it may come with the same or similar device.

I first came across the valve on the Alpha with the 50L storage.
