Any one use a ventless gas stove for heating.???

Today's tighter construction also traps in much of what used to be vented through all the leaks in the doors, windows, etc.

And allows in less fresh o2 rich outside air also.

The only reason my wife and I are alive is because I bought a CO detector and plugged it in for the heck of it. We came back from vacation late one night and turned the heat back up...

We had a similar experience although it was in a RV. We left the generator running so we could run the heater at night to keep warm. There was a path for generator exhaust to enter the living compartments. CO detector went off and saved us.

I bought a second CO detector and a heavy duty fan which I used to direct the generator exhaust away from the RV. This solved the problem, but was obviously not ideal...

The only reason my wife and I are alive is because I bought a CO detector and plugged it in for the heck of it. We came back from vacation late one night and turned the heat back up. The gas furnace had a lot of heating to do since the structure was quite cold. At about 3 AM we awoke to what I thought was a smoke detector. Tracked it down to the CO detector reading alarm. At 3 AM I am picking at the battery cover..... But then I decided to step outside with it. It went back to Normal ! Back inside with it, went into alarm. I did this a few times, then got the wife and dogs outside. Wife was rummy as were the dogs. Carried the CO detector into the basement, the detector shot up to lethal levels! Holding my breath, I turned off the gas, opened the doors and turned on all the exhaust fans in the house

Turns out the furnace, which was only about 5 years old, had been made in china to a lesser spec and was involved in a law suit we were not made aware of. The installer may have, but we were not made aware. The exchanger rusted through and was pouring huge amounts of CO up the exhaust vent. Coincidently, the installer had drilled a few small holes in the stack (to test I assume). Those holes were pumping the CO into the basement itself.

The exchanger was replaced free to me and I put screws in all the test holes. AND, now I have 3 CO detectors.

Another reason to have your equipment checked by a pro every heating season..I really don't know what brands are being built in china... some heat exchangers rust out due to moisture, some split open from expansion & contraction of the metal
