You say you were talking to marketing men of boiler manufacturers, which manufacturers were these
A number all were eager. At least they will look at it.
and what the F**k do marketing men know about boilers, as their name implies they are merely in marketing, they know nothing about the technical side of boilers.
They know about boilers and what the market wants - that is their job. If they decide the market needs a boiler that can be externally mounted, R&D get to work on one.
They liked the idea of no fluing problems - and all the rest.
They know nothing about boilers, they are salesmen, there would be a cost implication to a company to start changing their boiler design, most companies will not go for this expense, as there is no demand, having boilers outside, most people would not want this or like the idea, that is why nobody makes them, it would be great if when building new homes they made a plant room especially with all the new technology availiable, but they will not, again it has a cost implication,
Having a jig that can be piped and the boiler fitted later is nothing new.
You still have not answered the question, why have you advised people on this forum to fit the Vitodens 333 and the Alpha CD50 both of which have an unvented cylinder, after all your claims of how dangerous they are.
