I hope someone can help me. On one of Bob's shows I saw a small boiler unit that was very compact and very eficient. I believe that on the show the gentleman tht was showing it to Bob said that the technology for the unit actually came about because tthey were trying to build a steam car. It didn't work well for a car but it was great for heating. Very compact, quite, easy to istall & efficient.
My question is does anyone know of the manufacturer for this or any other god, small unit suitable for closet instalation on a second floor of a house.
