I'm building a sauna for my Finnish wife. We're installing a wood stove we got for free and I want to add a stainless steel water reservoir to thd interior of the Firebox. How do I legitimately run the two stainless pipes through the wall of the stove where its sealed? Also, how does a fella maintain the reservoir in terms of the calcium scale that builds up in the reservoir? Can the reservoir be periodically removed and filled with some form of resolver?
