If you only want to prevent heat rising in the cores, you could stuff the cores with rags or something... umm, maybe something noncombustible :)... and only need a small amount of grout above the level of the heater top.

 Yes Glen, that's another option. I guess, full concrete blocks could be the solution, or shuttering blocks. Or pouring a big lintel, if i want to keep it insulated a bit.

And the final answer is, yes you can make pizza in my rocket.




So that's a black oven?



Yep, black oven. I love it.

Yes Glen, it would. Since, here convection is the problem. I have may be 50/60 cm between the stove top and the beam, the wall is only 20. So heat would travel faster to the other side, than up. I ran it today, without problems. It's gone hotter outside. And with three burns, it's too hot in the flat! It was really cold the last few days. Hence, me pushing it, and having problems.

Glenn Herbert wrote:I have figured out the second IR photo, with the dark silhouettes of pipes running across the top. The 146.9C reading is on the surface of the wall just below the beam. The exposed beam is considerably cooler, but the back of the beam in contact with the wall would be as hot as the wall. I think quick action is advisable.



Yes, exactly. The beam is at risk. I have asked a mate of mine,; how much it  would cost to make that wall, with full concrete blocks. I guess he'll pop around tomorrow. I'm cooking a boar's shoulder "ham", right now.  And the temps are far cooler around the beam, for the moment.  Yesterday was very cold for the place i live in. And i might have overheated the wall. But i don't want to be in that situation again. So, yes, quick action is required.

Nope, this is the wall overheating.

Have you seen the thermometer?

That's about 700c°

I know Douglas. It is not too close. But the bricks behind are hollow bricks. And the heat from the "barell's" back, which is in contact with those; rises up in the bricks.

The first step, I think, would be to drill holes in every  cell of the bricks,  nearly all the way through. On the backside. So the heat escapes on the cold workshop side.

And may be in spring, I will shutter and pour concrete in there. If the temporary fix doesn't work.

But if anybody has some other ideas. Please tell me.

Hi everybody.


Sorry; i know this is not usually allowed. But i would like to redirect you all to my build thread. I scared myself tonight, with wooden, beams above the stove; reaching 140C°, well above the cooked wood auto ignition level.

Please, if you want to help, go there

Yeeehhh hhhhaaaaa!!!

But i admit i have a problem.

700C° or so in the oven, that's a first. -19C° this morning only -10C° at the time of the pic.


But my beams above the stove are cooking. It is said that wood can auto ignite at around 68C°, when well cooked.


But my beams and floor above are, on the edge, at about 130/150C°

The smell of cooking wood is present too. That is shit scary.

Anybody has an idea?

Sorry to other staff, but i'll start another thread about just that. To get more coverage.

It already bears the right name, "mass heater" just forget the Rocket part for the general public!

Well  everybody.

I have to admit, i have made a mistake. The first hit of proper winter has come, the last few days. Snow is falling outside.



If you look at this photo, you can see a very hot stripe next to the oven door on the right, going down to the cooking plate. I wanted to get rid of that "direct heat" feature, to stop overheating the flat.
So i piled firebricks in the  "barrel"  against the square exterior of the heat riser. To stop hot gases to come to the left, you can already see the divide on the photo above, before the modification. I have a gap of about 2 inches, between riser and front of the "barrel" So it was heating a bit less.

The result of this, i have lost 5c°  in the flat at night. And the next morning, i'm down something like 2c° or 3c° In the evening, i'm down to a rather even 17c°/18c°

And my chimney temp, next to the mass is about 40c° hotter on average.

The future plan, remove some of those bricks. To get back some direct heat. Prepare for the  Upstairs mass piping. I'm struggling finding some stainless 20cm single wall pipes and elbows. To pipe the upstairs mass.
