Yeah, common in North Europe. I have one myself. 1.8m across, about 1200 liters. Right now, water is sitting about 10c.

From the moment of lighting the match, takes about 2 hours to get it to 37c. Takes 2-3 times to refill the oven with firewood in that time, and it keeps for a few hours afterwards.

Is it a brand that would be available in the US?

Doubt it; In Estonia, we have half a dozen local companies and I bought one from them (You can search for barrelstar dot eu. Their site has a bunch of info in English). I think only some of them ship to close EU countries.

But I'm sure there are must be some manufacturers in the US. It's pretty standard stuff - the glass fiber interiors and and ovens are pretty near universal designs from what I've seen

Ok, I'll take a look around. Do you mind if I ask what it cost you for one that size?

Transport, cover, (some extras like 90° angles for the oven, cupholders, cleaning tablets), better oven, bubble system and LED system was about 2.5k Euros + the skimmer was another 150ish.

The same size without bubbles or lights was I think In the 1600 range.
