I think that you have to go for a 1st class modular oven...there's lots out there including Liam's selection (Kilnlinings), to achieve the same heat mass/performance as a self build fire-brick oven, but if you take the Bushmans oven from Dingley dell as an example www.dingley-dell.com/inc/sdetail/2539/2568 ...his 90cm oven costs £1500 but worth every penny in my eyes......but my last 90cm self build Pompeii only used 130 fire-bricks for hearth, dome and entrance arch. Total cost for the bricks, insulation blanket, mortar mix and vermiculite was about £400. The base is an additional cost but you can make this as elaborate or as basic as you want.
Total cost for a self build (using fire-brick and all the correct refractory materials) can be between £600 and £1000.....upwards and take 2 weeks to build.
They can of course be built for next to nothing using re-claimed materials.
The choice is yours, but for me.....and many other members the satisfaction of building your own oven gives it's own rewards.
Yes id love build own. Just 2 year doing house up and 1st year have garden use so like get bbq and oveb ready. Fast. I have supplier, dineens refactory supply the bricks or oven precast kit with same materials as brick. Just if brick better ill go brick built.
Have enough brick free to do small to medium barrel oven. But lot saying its not best shape
I have built two concrete ovens (one in situ and one modular) and a brick oven and the brick oven was without a doubt the quickest and cheapest to build, I used regular clay bricks (cut in half) for the dome and refractory bricks for the hearth (Old storage heater bricks etc would do for the hearth to save money. I actually used regular portland cement and the oven is still standing 4 years later including being at the epicentre of a 7.6 earthquake ( www.ctvnews.ca/world/magnitude-7-6-earthquake-rocks-costa-rica-does-little-damage-1.943326 ) I always recommend the brilliant book by Russel Jeavons "Your Brick Oven: Building it and Baking in it" Good luck
have 4 bags of premixed "furnace cement" in shed for a year or so. mus mix bit up see whats in it and if still fresh to use. i know standard cement be hard buy now but this still looks loose so must read the descrition of whats in it
