Thanks for your replies fellas, much appreciated!

how many storage heater bricks did you use?
what mortar did you use?
how did the former work?
any other info you think might be useful would be gratefully received.
many thanks in advance.

As the firebricks are really expensive in the UK, you will find the heater bricks are as good.However they don't take alot of load. Therefore your dome should not exceed 60cm in radius.
The heater bricks are much easier and cheaper to cut to size.
Watch out for the ones made of Asbestos!!! as certain heater bricks ( the ones that Kellerman had used don't have the dreaded asbestos, watch out for the older version of the heater bricks).
You can cut the heater bricks with a wet tile cutter. You will save huge amount of dosh this way.
The thermal storage and efficiency is nearly as good as firebricks. If you want to do the mortar the cheap way and more effective way, I would use Lime:fireclay;cement: sand 1:1:1:3 for the mortar. There is a very informative thread by Crisp on this mixture https://community.fornobravo.com/for...a-hobbit-house
You can buy the lime cheaply from Selco. As for the fireclay, there are couple of suppliers near where you are situated up north.
Speaking of northern England, there should be few cheap suppliers of firebricks manufacturers, especially near Nottingham.
Avoid Travis Perkins for any building materials, as they are expensive.

Several other UK builders have used heater storage bricks in their builds. Kellerman has not posted in several years so it is uncertain he or she is still active.

Hi Kellerman, that’s a fantastic looking oven!

How’s are the storage heater bricks holding up? I’m looking to build something similar as I can often get hold of the bricks but I think that there’s to much work involved for them to not last very long.

id be grateful if you answer a few questions that I’ve got:

how many storage heater bricks did you use?
what mortar did you use?
how did the former work?

any other info you think might be useful would be gratefully received.

many thanks in advance.

regards,

David

thanks Dave, you were right on the door , the heat went through the vermiculite and set the maple door on fire ! so I had a simple metal blast type door made which is working out much better.

G'day
The insulated doors used to retain heat in the oven so when fitted good and snug will kill the fire . Heat will remain so you can bake and cook over a number of days.
A loose fitting door can be used to reflect the heat back into the oven but an insulated one is a bit of a waste . A " blast door" type needs only to be made of steel non insulated to do its job. And its job is with the fire in the oven

Hi - a question - I'm about to start on the door ( maple backed with vermiculite board ) - what kind of gap should I be leaving at the base so the fire gets enough air ? thanks
