Not so good if there is one of those hot water re-circulator devices installed already.  

It is a good SCREENING device that is worshiped all too much on BP.

I believe if you're on a mobile device the @ mention doesn't work.

Cozy will work on any mobile device or tablet.  

As @Dawn Anastasi just posted, the gas company has techs that come around with their "sniffer" device to pinpoint leaks.

Take good photos with a high-res device that will translate well digitally, write a great ad, and advertise it well online, and you should be good to go.

From my experience, I can also spot the difference between a floatation device and a shark, and occasionally enjoy going shark fishing ... most newbies can't and believe in fairytails because they want to and there are plenty here that are happy to cater to that tenancy; I'm not one of them, so I guess that makes me a fear monger; some people have to learn the hard way.

Well, the next day I called my local Home Depot store, briefly summarized my experience, and was given another number to call which turned out to be a scam attempt as the person who answered the phone told me that, if I was over 50, I was the lucky winner of a personal safety monitoring device, then asked "Can you hear me?"  

Technology is major for us; we're early adopters of new devices and happy to discuss and advise peers about technology.

Yep, every unit has its own separate gas meter and in unit furnace/heater one has a fireplace that is rated for use as a heating device.
