Need help with design/process of a system

[Chris Hoskin]

here is a photo of the inside of a Tarm 2000 / Solo Plus wood boiler upper firebox. This is from a cutaway unit we have in the showroom/warehouse. The loading door is on the right (just out of view) and the heat exchange tubes are on the left.

I understand now, the stays are just tabs from adjoining braces and plates that stick through that are welded inside the fire box. So you're saying that they are more than likely worn off. Are the stays only welded on the firebox side of the plate or are they also welded on the outside of the fire box as well?

I appreciate all the information...

They are welded on the inside of the firebox and the outside of the boiler. They go from the outside of the boiler through the water jacket then through the firebox wall (welded at both ends). Think of a bolt going through both walls of a concrete form - keeps the walls from bowing or blowing out under pressure.

Chris, any idea on value?

 

[Chris Hoskin]

no, sorry, local market and how easily you can move it are the biggest factors.

Quite by accident I saw this CL post for a Tarm for $450.
