It's a very cost effective fix we did until we installed on-demand direct vent units.We also have direct wired CO/SMOKE detectors within 6 feet of the hot water tanks etc as per bldg inspector.http://www.woodlanddirect.com/Chimney/Chimney-Liners?

If the alarm goes off it alerts me and calls the police.I put a wireless sensor on the front and back door, then put a motion detector in a place someone would walk by,,,it cost a couple of hundred dollars, the monitoring is about $30 a month, but when I'm between projects I just have the monitoring shut down...Its very simple, about as cheap as I could find, and it works greatandy
