This is the HX slide in room or I'd say...being in FL I wouldn't think of an EZ, when Judsons are built there, but I'm thinking LP fired heater TNT, so for HX you would be looking at a Reactor, it cost more than an EZ, is stainless etc.......but it'll be reliable and work for you every morning, and every night, you won't ahve to be a mechanic or worry about losing sleep.
