Heat Radius - Forno Bravo Forum: The Wood-Fired Oven Community



New Forno Bravo Forum Feature

Forno Bravo Forum Community,

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

    Hello Everyone!

    I've been thinking about building my very own wood-fired oven and have several questions

    1. How hot is the area around the woodfired oven if the oven is igloo shaped with only the entry point as an opening. If I were to build it under a pergola with a plastic roof would the heat coming out of the oven melt the plastic over time?

    2. If I were to build it outside how does a wood-fire oven cope under rainy conditions? Would placing a tarp over it be sufficient or is there more involved?

    1. The chimney is the problem, not any heat coming out the entry. Your chimney needs to be two feet above anything within ten feet. Having a short chimney under a plastic pergola isn't going to work.

    2. In wet conditions you may want to choose the house style enclosure rather than the igloo style. An igloo can be made completely watertight with pond liner or roofing membrane, but the standard stucco (render in australia) is pretty porous. Or you could put roofing on the part of the pergola that covers the oven and just worry about flashing the chimney.

      Hi andypants and welcome aboard.
      You will need to slip a section od colorbond steel sheet into your pergola above the oven chimney and cut a hole through it for the flue/chimney to pass. My chimney was sleeved with another round section and the gap between them filled with some superwool insulation blanket. The largest rubber sealing plate from the plumbing wholesalers was then placed over the pair and siliconed to the metal roofing sheet. It seems to be working well and stands up to the heat that is transmitted through the gap and insulation.

      Prevention is better than cure, - do it right the first time!

        Hi Andy and welcome to the club,

        I have an Igloo oven outside for over a year and have no visible signs of weathering. Though I often want to throw a tarp over it, It is constantly in use.... Have you started yet ??? and remember we love pictures...
