Okay, a three port valve sends water in one leg of the valve and can allow water left or right or left and right out of the other two legs.
Is there such a thing as this...
Imagine the T shape of the valve. Water enters from the top left. Water enters from the top right. The valve can choose which flow to allow down the vertical.
Why?
Well I am looking at the various ways of adding a wood burning stove to a system that already has a combi (feeding rads) but not a modulating combi that can accept preheated water. One way is to direct water from a cylinder (preheated by wood burner) to the valve and to direct the combi to the valve as well. The valve can then be switched between one or the other depending on requirements.
The valve can be manually operated maybe (I can use combi as back up for HW) or maybe even directed by a stat on the cylinder to "switch to combi" if cylinder drops to a given temp.
Apologies if I have made any daft assumptions or points at this stage as this is early research.
