Conservatory temperature piece of mind please.

Thanks for the opinions everyone. Are definitely going to have something between them now, a new double glazed window and a door, probably still an internal though. With that and the under floor heating which should cost about 10p/hour to run hopefully that will be able to keep the temperature consistent without changing the temp in the kitchen too much.

My wife is currently on maternity leave, but she runs her own baking business from home, so the kitchen is normally stinking hot!! So may even balance out the temperature.

Would be interested to know if the people who have commented have all glass or some brick, and if they have it open to the house or something between the two.

Thanks again.

I have followed the thread having done something similar with my kitchen.

My intuition is 10 pence per hour will not pay for the heating, and you will need an insulated external door between the kitchen and conservatory. (This being the Building Regulations issue)

My work was a brick extension with extensive glass and a tiled roof with extensive Velux roof windows. This is very heavily insulated but it faces south. It still gets hot in summer (to compensate I introduced thermal mass into the design) and has a noticeable heat loss in winter

I would not entertain the conservatory idea if south facing. Equally if north facing or over shadowed north facing there will be issues of cold, damp, algae etc. Further do not overlook the wind chill factor on conservatories and on double glazing - I do not recall ever seeing any research or guidance to advise people on this.

Maybe more than 10p, but to be honest I don't think it's going to be over the top on cost.

The door issue, your saying that purely for building regs, or the fact an external door is more insulated?? Building regs I can get, so that isn't an issue. I'll try and post some pics of the plans up for people to see. It's not a massive space, and we're having a fair amount of brick, so I think all that combined with keeping the window and an internal door I'm happy. The sun rises at the rear and sets at the front, so I think it will be ok from that point of view too.

i really don't understand the insistence on not having external grade doors and windows between the two rooms and meeting the requirements for exemption - getting building regs approval will cost more than the difference between external and internal doors/windows and you will get a much better end product with decent door/window - you've put this thread up to ask for advice and almost everyone that has posted has advised doing it the right way but you are not heeding the advice, which makes me wonder what the point in the thread really is

The point of the thread was to talk about the temperature, it's not me that has been fixated on building control and I never ever have had a problem with that or cost!

But you are quite right, I have all the info I need from the thread and peoples views have changed by mind on things. The window WILL be external grade, the door may or may not be, I don't know yet.

Feel free to close the thread.

and what do you think the purpose of have external grade doors and windows creating a thermal barrier between a conservatory and house are there to do?
The whole thing is related to the heat/cold and the heating requirements - and that's the reason building standards are there, and why they have specific requirements for conservatories (and specific definitions of what makes a "conservatory")
