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.

Ask Me Anything New Forum Feature

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.

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!

  • Using Residual Heat?

    I have a 42" Pompei style oven. It is used twice a week for bread baking. Now that winter is just around the corner, where I am anyway, I am thinking about installing a water coil around the exterior of the oven and using the residual heat to augment our inside wood stove. The existing insulation is 24" of fiber glass batts , so the install would not be too difficult. Just wondering if anyone has attempted the same. any thoughts?

    Re: Using Residual Heat?

    I have heard of others trying this. There are several big issues.

    First is corrosion. Higher temps greatly increase corrosion.

    Second is that there may be a lot less heat in the oven than you think. Most of the wood heat goes up the chimney.

    Third is you don't want to boil water in the coil - at least unless you design for it.

    Fourth you probably only want to use it to capture heat after baking but that can be a problem for if the coil is empty it will be hot (and boil the water). And if you have water in it it may boil.

    This deserves some pretty careful thought and planning. The results can be anywhere from great to mediocre to rather dangerous.
