CO Detectors with Boiler Shutoff?
Getting a boiler installed this week; I've heard of the Aerco CM-6 and Honeywell E3 CO and Gas detectors that can shutoff boiler and thought of having this put in. But I'd like to hear from anyone that's used them. My concern would be an off switch in case you get false readings that turns the heat off in dead of winter, longevity--most CO detectors last 3-5 years, reliability, etc. It sounds like a good idea but if a good tech does a combustion test annually isn't that enough? (Of course that wouldn't cover a natural gas leak.)
