Hi! I have an old Broomell vapor system with a Weil McLain SGO 7
It's powered by a Carlin (converted) gas burner. System runs perfectly, however, I'd like to replace a small sectional floor radiator with a 2,500 BTU hydronic towel radiator (details on the unit and manual below). Here are the questions I hope someone can answer. Greatly appreciate your thoughts, thank you.
1. The towel radiator manufacturer will not warranty the unit unless a rust inhibitor is used. How can I add rust inhibitor to the Weil McLain SGO 7 and is that prudent? I don't see it referenced in the manual.
2. Can this towel radiator work with a two-pipe vapor system? It works with water, so presume it will work with lower-PSI vapor, but would love confirmation on this. It also asks for a closed circuit, which I assume is no different than the other appliances I have on this system.
3. Should the towel radiator be installed (assuming positive answers to 1 and 2) pitched slightly so that the supply line is higher, allowing gravity to pull the condensation down the return line, and if so, what is the recommended pitch?
4. The towel radiator is rated at 2,500 BTU for water. Would vapor emit higher, lower, or the same BTUs? I appreciate that vapor is hotter than water, but would the density of water (and thereby heat) emit more BTUs?
