I was asking about roof mounted ASHPs some time ago. Again the UK authorities lag way behind Europe. These units are now regularly put into pitched roofed terraced homes in the Netherlands, Bosch and HydrotopWorks BV supplying the heat pumps. They are inserted in the same manner as Velux windows. In the UK they are not permitted it seems because the said authorities envisage them to be the same as ground based units.

An ASHP wouldn't be feasible as it would technically intrude into private space and through the wall pumps I have no knowledge of. I referenced a roof mounted unit which would be internally accessible and inserted much like a Velux because there is cuurent experience of them in the Netherlands. But I don't have any idea of the British development control attitude. Many thanks for comments. Helen Carpenter

Hello, I am a new member, a retired historic buildings carpenter and earlier a timber framer. Though based in Czechia my original contact was with reference to a property I have in the UK, a small terrace cottage with no outside space only foot access at the rear. Having read about air source heat exchangers being fitted in the Netherlands on just such terrace roofs I wanted to ask what the posibilities were in UK.
