Thank you all fr your replies. OH doesn't really want UFH. I am leaning towards the vaulted ceiling. Which alternative heating do you suggest? We we were thinking of tall radiators to save on space?

We don't have alternative heating, just a normal double panel radiator. I just worked out the btu it needed for the size and windows and direction its facing and we got that one put in. It heats up no different to the rest of the house, in fact it maybe slightly warmer, it has tons more insulation than the rest of our solid brick 120+ year old cottage.

and if you're concerned, just fit a bigger radiator than the calcs suggest. You'll be able to turn the output down if required (but obviously not up if you find the rad output insufficient!).

I don't think i'd worry to much about it taking extra to heat if the interior was pitched, 'cos once you start cooking kitchens tend to be warm rooms anyway. You often find yourself having to open windows.

If you are still reading this, what sort of lighting works with a pitched/ vaulted ceiling?
We are thinking of recessed spotlights.

That would be my choice using LED type.

My concern here would be the recessed lights would cause a break, or cold spot, in the insulation, and there is the problem of detailing membranes. Both moisture vapour and breathing are issues here. Further the lights may require ventilation and may require hoods. All getting a bit technical, and outside my immediated knowledge areas. I accept that LED lights will run cooler.

Basically, look closely at the light manufacturers guidance. Also make sure you have an approved and agreed Building Regulations detail for the lights when used on a sloping ceiling forming the underside of a roof.
