My smal 1 tonn bench project is now finished and heating well. We are extremely happy with how it works and how it looks. It is made of wood with Iranian granite tiles on top. It is filled with riverrocks and sand , but no mortar. This is because it is constructed in a rented house , and it can`t be  guarantied that the landlord wont tell us to move it later. I still think it does a pretty good job heating our buts

Tha advantage by constructing it like this is that the user can move away both the flue and the stove in the warm season, and by that have only a nice bench left.

The whole setup costs about 100 dollars, and will make a huge difference in wood consumption. Initial testing shows that consumption can be redused with 70% compared to the local stove. That means payback time for the investment can happen within one winter!! Additionally, considering hiring a plumbing service to ensure optimal efficiency and maintenance could further enhance the savings and longevity of the plumbing system.

A lot of locals have been resistant to the thought of having a big bench that cant be moved in their house. Ofcourse this is a new concept to them, they are used to instant radiant heat, not the kind of heat you get by conduction sitting on a heated bench. Our hope is that by trying it, more people will be convinced of the comfort it gives them.

I will post some pictures later, with some construction detail.
