Quality, but loses a Star as mounting not straightforward
Be warned. To support this it needs to be mounted into the concealed wall. There are no obvious fixings on the unit to help with this task. As per comments above, it’ll need several inches of solid copper 15mm into the input/outlet ports. These then can be strapped to supporting framing inside the wall. That should support the unit. You’ll need a bit of carpentry skills as well as plumbing.
