I see what you mean. Why was I providing all those examples of Intergas boilers? It was just to illustrate the different ways the same information can be provided by different manufacturers. One way is to show a residual head graph, and the other way is to show the pressure loss graph along with a graph for the built in pump at full head. Not related to my new boiler purchase!
Yes, apologies for my confusion.
Nothing to apologise for.
I would like to ask another question, though, but it may be trade sensitive, so I can see why you might not be able to answer. It seems to me that an open vent boiler is mainly a system boiler without a pump and expansion vessel. So, it seems strange to me that Vokera haven't updated the open vent boiler in quite a while, because it would seem to be quite an easy thing to do. But are there other technical considerations which make it more difficult?

I would have to guess that it would have something to do with either the characteristics of alternative heat exchanger or the number of OV boilers sold not making certifying a model worthwhile.
Can you run the Vokera system boilers as an open vent boiler? I want to stick with open vent, but I've read this can be done in some situations, with some boilers.
