Yes Mike that is correct, just to round up we live in a single storey house it is "low slung" ie: roof pitch = 25 Deg. the internal hieght from floor to underside of the roof apex is barely 12 ft.
One top edge of the main CW tank is right up against the ceiling at the highest practical point. The ceiling is vaulted ie: it's the underside of the roof) this leaves a "shed" as in weaving warping etc, that area is just large enough to get a CH header tank in, the top side of one of its edges is also right up against the ceiling (underneath side of side of roof) The stove is approx. 3 ft high and stands on a 4" hearth, the top of the boiler outlet tappings are at the same hieght less about one half inch. The HW tank is approx 3 ft high so as can be seen the scope for a steep and therefore fast gravity flow at start up is greatly reduced hence the little problem when first firing up with a fast burning fire, I could fire it up more slowly but this gain would be offset by condensation problems in the last few feet if the chimney/flue before that chimney/flue has had time to heat up past any critical dew point.
The trick that Paulas dad used might apply to a different situation that what I am describing, so I will see if Paula can describe in more detail.
