Amtrol does NOT manufacture an expansion tank listed for fire protection use. The Standard requires a LISTED expansion tank. Young Engineering is the only company currently manufacturing expansion tanks listed for fire protection use. Forest Wilson Cherokee Fire In a message dated 10/25/2007 6:33:20 P.M.

I would suggest you consider Amtrol's Fire-X expansion chamber, I found them to be a bit cheaper, they assist with sizing (glycerin's expansion is much less than a glycol-water mix so the chamber size is smaller than glycol) and will send you the selection paperwork and sizing help. I asked about software and was told "soon". It was a benefit for me that they were in New England (RI) too. Build a closet, insulate it and heat it. Funny you mention mid-landings. We started doing them as well, more for liability reasons. We also do Bathrooms if they have any in their Basement. We're seeing a trend for a half bath in many single and multi residential projects lately, and garages under the living areas in part of the Basement or stepped up, attached. I just do a 2 or 4 head calc (if they have that many) on the dry heads for the garage. Tom GRS Not to mention a listed expansion chamber. Which in some cases is the most expensive part of the equation. Richard L.
