Park Oven Progress

Re: Park Oven Progress

Another possibility might be to pull up the floor bricks, put down 2" of insulating board, then reinstall the floor.

Since the entry and dome are not yet complete, the design could be modified to accommodate the elevated floor.

It wouldn't be a perfect solution, but should be better than putting insulation under the hearth slab.

That, I think might be the easiest fix, leaving only the bottoms of the dome wall uninsulated. But I think heat loss around that entire perimeter could still be significant.

Re: Park Oven Progress

I personally would tear down the partially built dome and install proper insulation between the slab and the oven floor. There's no telling how the oven might perform simply by insulating under the slab. Heat will still bleed off the edges of the slab and into the cinder blocks on all sides. The oven floor must be completely isolated from the concrete slab for optimal performance.
I'm sorry to see this happen on an otherwise fine looking build.

Re: Park Oven Progress

You always have the open area underneath to fill with insulation..

Re: Park Oven Progress

Thanks all for the feedback .... and i have had a look at your ovens .... unreal!
am now thinking that i may have to do some insulating underneath ... by what you are all telling me.
will concentrate on the dome etc for now and later on will modify the underneath of the slab with insulation.
this will give me thinking time of how to go about it as i may have to take a different approach to do it.

Re: Park Oven Progress

Warren,

We are concerned that your oven doesn't have any insulation UNDER the cooking floor. From the pictures it appears you placed your floor bricks right on the surface of the concrete hearth.

Re: Park Oven Progress

errrr ahhumm ... no insulation on the hearth

Youll be pushing to get the oven to retain any heat without hearth insulation, all the heat will just flow out of of the floor..

Re: Park Oven Progress

gooday ken524....
i will be insulating the dome at a later stage during construction.
have not had a chance to work on it because of the weather and other commitments. fully intend to get into it again very soon and will post further pics.will have it fired up before xmas but not fully finished.

Ouch.

LOVE your stand design and your work looks great. How far along are you on the dome? You might want to take a break and think about that insulation.

Re: Park Oven Progress

Very nice setting for your oven! Nice looking build as well. How is the hearth insulated?

Re: Park Oven Progress

Yes Neill.... point very well taken .... but was toooo far into it before i realized the footing was lacking.
Have added extra steel into "top slab"
Inside diameter approx 37"
Location Port Macquarie N.S.W. Australia

Re: Park Oven Progress

Hi Warren and welcome aboard.
Where abouts in this wonderful country do you call home?
What oven and size are you planning on building?
Good to see you well under way BUT mate, well I would have dug a deeper perimeter beam footing and located a dew extra 12mm reinforcing bars into them. Remembering that the total mass of your oven will be resting on this perimeter area of your foundation and will need to be strong enough to support over a tonne in weight.
Anyway, keep the pics coming.

Cheers.

Neill
