Flue pipe was tough to get out but it worked a treat.

I'm also using a 4" batch rocket to heat our homes water through winter with excellent success the entire season.
Thermosiphon to a low pressure tank on the roof was the solution we used.

It has been some weeks since I had time to work on the heater! Today we cast the top of the bell.  

Cheapest I can get in Australia are $4.60 per brick. I'm picking up a heap of seconds today for $2ea to finish my project. Hopefully the condition is OK!

Have been away for work for a bit but I'm back into it again. Cut the water heater to size today. Looks to Ben 4mm thick. I can get steel in 3mm to weld a lid onto the thing which I'll do tomorrow.
ISA is 2.265sqm.

I believe it gets up to temperature quicker with less mass.

I see..
These things always come up after I build the hard way haha.
Should be quite easy to cut the chamfer out from behind the port at least.

It looks like I should also exclude the ramp if I understand the article correctly.

Nice video! Do you mean the 45 degree cut at the back. So it looks more like this?
But only the 3courses of brick at the port level?
The 2nd course is like this. The other two would need adjustment to the bricks. But no problem.

The resource is so amazing, Peter. I've shared it with many people. Some who intend to use it for their own build.

I cut the bricks that I had on hand today. She's not pretty from the side due to the brick layout but the riser is nice which is what matters! I decided to put in the extra effort and cut bricks to make the riser lock into the fire box also.
Port ended up being 59mm rather than 50mm but not a problem I think.
I need to collect another 24 bricks for the fire box walls and the floor to finish it.

From here a plate will go on top with a hole over the riser to insert the insulated flue pipe riser.

Will probably enclose the entire core in a steel box and slide it through into the bell and seal the edges.
