I like the way you think. you will want to have some flower, mozzarella cheese, and marinara gravy on hand in case a code enforcement official stops by. You can offer him a slice!Edward Young

It takes a good sized fire box to get enough BTU for home heating. Look at the smallest OWF to get an idea of how much volume you need.
Maybe a cast iron radiator for the grate, keep it in the hot coals.
Start cutting now, you want dry wood to get a clean hot burn. A moisture meter is a good investment.
Of course you will soon see that you need a buffer, or run out every couple hours to load woodIt's not as easy as it sounds or looks keeping the heat on with outdoor wood burning.
IF wood burning is in your future, look into one of the Euro parlor stoves/ boilers with gasification technology. Less wood, less smoke.Bob "hot rod" Rohr

In order to "really" cook pizza, you want to get the firebox up to 750°, and I don't think that the water filled radiator will allow that temperature. If it does get that hot your oven/boiler will make steam and blow off the relief valve. So don't forget the relief valve.
But I don't think you really want to cook pizza. As long as it looks like it can cook pizza is all you want. In order to make it more efficient than a typical pizza oven, you will want to insulate the exterior and have a closable fire door. Perhaps you could take an efficient wood burner design and make it look like a pizza oven.Edward Young

Yes, if you want *really* good pizza. I make pizza at home and can only get to a measured 525F in my electric oven and it does a pretty good job, but if you're a fan of NY/New Haven pizza, you need at least 700F to get there.EdTheHeaterMan said:In order to "really" cook pizza, you want to get the firebox up to 750°

Mine gets up to 750F which is the sweet spot for Neapolitan pizzas and it takes 90 seconds to melt the cheese and cook the toppings with a nice browned crust.
I wish I had thought of adding some thermal mass, supply and return pipes, relief valve, tempering valve, buffer tank.........
Often wrong, never in doubt.3 -

What about an indoor gasification boiler ?0

The gasification stove I posted above often have a HX add on for heating water. Usually a potable water application external to the stove. You see all sorts of these at the ISH show fireplace halls. When you see the bottom chamber those are gasification designs.Hot_water_fan said:What about an indoor gasification boiler ?
Marc Caluwe imports different biomass products back in MA. Caluwe Biomass Systems woodchipboilers.com
May as well make electricity and heat energy with a rig like this, shown at his website.
I think I spotted some Caleffi components on the machine.Bob "hot rod" Rohr

==============================================================Stormjib said:Thinking about a block fire brick oven /pizza lined with some recycled cast iron radiators , maybe built into the walls in some manor piped into a 500/1000 buffer tank heating a home ? Crazy thought but oil is getting scary and out door boilers are illegal in my area but out side pizza ovens are not.
If your worried about oil prices and forest eaters/outdoor wood boilers are not legal in your area you can always use a small coal stoker boiler to heat your home without a buffer tank and a coal fired pizza oven.
The smaller table top propane fired pizza ovens will cost you less money and create less work.
Wood fired gasification boilers require very dry firewood and will build up creosote quickly if it is not dried down to 15% or so.
Wood pellet stoker boilers and wood pellet stoker stove as a rule use 2 tons of wood pellets for every ton of anthracite coal burned.

On larger boilers it looks like chips are more and more common. A few less steps to process compared to pellets.leonz said:

Hello Bob,
We have been using wood chips for biofuels for a number of years now here in the east.
The salt brining and evaporation plant on the west shore of Seneca lake has wood chips delivered by rail car and they have been using wood chips to fuel its boiler for over a decade now using a concrete stave silo to store them.
Fort Drum has used wood chips for almost 2 decades+- for its cogeneration steam plant and is facing the EPA and thier new pollution regulations and may have to stop burning wood chips which for them is very bad idea as they would have to return to using Eastern Bituminous coal as a boiler fuel.
