Locating oven with pool nearby

Re: Locating oven with pool nearby

My oven also has the pool nearby and on occasion the smoke from the chimney will waft over the pool but because of minimal smoke coming out it is rarely a problem. The oven entrance faces away from the pool and is about 50 inches lower than the pool deck.

I did add an extra piece of 30 inch flue to get the smoke higher as the floor of the oven is almost exactly the same as the water level of the pool.

Gary, I think your prep table opposite the oven will work out great.

Re: Locating oven with pool nearby

I built my oven at the head of the pool. I set it back about 8 feet, and extended out the pool patio up to the oven. It looks great and I have no problems. I will be posting my finish photos soon on my thread "One small step for pizza" in the getting started thread. You can check out how it looks since there are some pool photos included.

I have measured the underside of the slab, but I don't recall the exact temp. My vague recollection is that it was something over a hundred degrees farenheit, but not a lot over...maybe 110 or 120. The sides and top of the oven are only 85-90 degrees F after a big, long cook when the ambient temp is in the 70's.

My floor insulation is three inches of Insblock19 ceramic fiber board. The sides have three inches of Insblock plus an inch of ceramic blanket. The top is a mix of ceramic blanket and insblock19 layers totalling about three inches thick...with about four inches of perlite sitting on top of that to fill out the enclosure.

My "what would I do differently" file concerns the wood storage area. No big huge one one in front. I'd much prefer smaller ones on either side with a solid front wall to the stand.

Let's just say "point taken" on the mineral wool. I was planning to avoid it in the new build anyways, since it was kind of a pain in the butt to handle.

I have a grinder too so I know now I'll probably want that nearby when I'm cutting bricks and all. It's probably about time I started a build thread or something since all of this is coming up.

Re: Locating oven with pool nearby

I used a big old MK 2000 wet saw for the vast majority...but I occasionally felt the need to "touch up" a few things here and there. I really didn't do that much (went through only one blade)...but when I did the dust was flying. Can't imagine having done the entire oven with an angle grinder.

Bill

i think everyone has had touch up issues that were dealt with in a similar manner.

Your heat retention is great. Have you ever measured the temp under the supporting slab. I find my wood bin ceiling has reached 145 after long hot pizza sessions.

I have 2.5 inches of 7/1 vermicrete and 2 inches of FB ceramic board under the floor of the oven, and still am loosing heat into the supporting slab. For the what would you do differently file.... more floor insulation.

Re: Locating oven with pool nearby

What was certainly noticeable was when I was grinding brick with a 4.5 inche angle grinder I would get tiny little drifts of firebrick dust accumulating at various points on the bottom of the pool until the random pattern of the vaccum eventually got there.

I'm reading comments about that quite a bit. I should be more worried about the construction than the usage. How did an angle grinder work out for cutting brick? That sounds like a lot of work.

Re: Locating oven with pool nearby

It has been 5 day to the hour since I cleaned the ashes out of my oven to bake bread, the oven is now 160F, thats 5 days. I think the problem is the mineral wool which is not suited for the oven's prolonged high temperature.

Re: Locating oven with pool nearby

I don't recall for sure but it was at least 8:1 on the perlite to cement. I think I started at a ratio > 10:1 and worked it down as I went outwards. My current oven is clay with chunks of brick on it in the inside. The smell comes right from the front where the flame leaps outside. Generally my dome and door height are nonstandard. The door is 13.5 inches and the dome height I think is somewhere around 24 inches, over a 36" diameter floor. I don't use a door on it. But if I may say so, it's becoming a long derail.

Re: Locating oven with pool nearby

I beg to differ your 240f degrees after 12 hours, that is significant heat loss. Do you have a well insulated door? I am still above 240f after day 5 or longer.

Chip

Agreed. That is very significant heat loss IMO. I'm at over 350 twelve hours later if I completely leave the door off. If I close it up when it's still at pizza temps (approx 775), I am well over 600 degrees F twelve hours later. I'm at around 200 degrees at 96 hours after closing it up.

Not being braggy...just pointing out what these ovens are capable of if well insulated. If yours is well insulated, maybe the insulation is getting wet???

Re: Locating oven with pool nearby

I'd say say. At least four inches of perlcrete and then an inch of mineral wool sheets, overlapped. Over 12 hours later it'll still be at 240F. It's well-insulated.

Most of the bad burning is happening in the front when the fire first gets moving. It will come out the front and cause some trouble. It's making a nice moustache on the top front of the oven.

But yeah, oven and pool . . .

Re: Locating oven with pool nearby

My pool is nearly downwind of my oven. In the photo below the camera is facing southwest. The prevailing winds here come off the ocean at various points from southwest to northwest. I have had no problems with ashes/embers to speak of that I can recall, but even if some fell in, I don't see it as a big issue. Like everyone with a pool, we get leaves in our pool, bugs, and even a mouse once in a while. The skimmer, vaccum, and filter take care of that stuff.

Re: Locating oven with pool nearby

Hi Rocko,

Could that be your mineral wool sheets, she smell? Its limit is 432F and if you clear your dome, the temperature can double that, in addition the insulating value of the perlcrete is dependent upon its ratio of concrete, how fine its mixed and other factors? Just wondering?

Re: Locating oven with pool nearby

Didnt you insulate enough?

Re: Locating oven with pool nearby

she smells an odd burning plastic smell and it looks to be from charring the acrylic stucco on the outside of my current pizza oven.
