How Hot is too hot?
 
How hot is too hot? Well I had this and a few other questions answered last night/this morning:

After about 8hrs of oven use yesturday, (18 pizzas ,2 calzones and a few other treats) and it goes with out saying lots fo beer. We decided to burn off
all of our vine and rose cuttings.

The resuling fire was warm to say the least (for non-UK residents wiki: British understatement) The flames were not just going up the chimney, but coming out the top too (currently about 4-5 foot high):

After it had all died down, we closed off the oven chamber with a piece of plate steel and went inside.

This morning (12hrs later), the hearth was ~50C around the front opening, ~100C in the centre and the air temp inside was ~50C.

So I think a proper door will definately help with the heat retention. Though did notice something slightly amiss with the roof (again refer you to British understatement):

After taking a few loose tiles off, something seemed to be missing:

In hmmmm think putting that rafter against the chimney wasn't such a good idea!! Oh well, at least I know the rockwool can stand the heat!

Well rebuilding the roof will keep me out of misschief!

If i have the oven fired for around 5-6hours (which keeps a consistent temp of around 400 degrees celcius on the floor) about 15-20 hours later (if the door is left on the contain the heat) i have a floor temp of around 80-100 degrees.

I think once I have a proper door (ie one that fits and doen't conduct heat) I might be looking at something similar. (well at least 80C hopefully).

Differences in local air temps might play a part too ;)
