    Our CH boiler does have an internal expansion vsl for the heating circuit including the boiler side of the heat exchanger. The one we needed was for the cold feed.

    It was an easy job to fit one once it came into a local plumbers merchant. But it was special order, since none of the merchants stocked them! This was only circa 2008, so not as if a combi boiler was a new idea. The last one I fitted I bought off eBay.
