LOL @ $164.96. They are $80-90 everywhere. Still a good price if you need one.

Yeah, the MSRP on these heaters is a work of fiction. Nobody ever sells them at that level.
That said, this is a very well made portable heater from a great brand and a good price.

The only real downside to this unit is its small size. 9k max BTUs isn't very powerful, and running it at that level will eat through a 1lb tank of propane in just 3 hours. This definitely won't heat your whole house but it would be great for heating an RV or a van, or emergency heat for a smallish room.

We ride dirt bikes in the winter with studded tires. Very fun! I use this heater in my little box trailer when I'm changing into my gear. Saves me from freezing my b@lls off! I bought the adapter to refill my tanks from a 20lb propane cylinder.

I have the MH18B and have only had to use it a couple of times since I bought it in 2014. It worked really well during a cold power outage. I pumped the one bedroom up to a high temp and then removed it.

I don't trust it running with my family in the room, but it didn't register on the CO detector while running, so that's good.

Wait, you use the heater to heat the room and than remove it? Wouldn't the room get cold again? or you keep heating and removing the whole night?

I am thinking of keeping it low and also crack the door open. It'll heat the house a bit but mostly keeping the bedroom comfortable.

Anyway, I got this Mr Heater at Costco for $80 and it have the extra hose to attach to the propane tank. That should keep it running for awhile. Will use it for when I really need it. Or else the space heater will work fine for the bedroom.

You can see several detailed youtube videos about buddy and CO. You have a greater risk running out of oxygen before you get theoretical poisoning from CO. This is why it equipped with oxygen sensor and not CO sensor. you should know real but not imaginary risks. Many people including me are running buddy inside camping tents with no issues but you need fresh air intake to supply oxygen and remove water vapor.

Got the same Costco deal 1 month ago as well. Check Costco; much better deal.

Power outages during very cold weather are very rare here. The couple of times I've had to use it I heat to around 80F and then remove it from the room and house. Doing this once or twice isn't a big deal. I don't want to have to rely on a CO detector alarm to determine when to remove it. Maybe I was being overly cautious, but that's OK with me.

Same where I am. It's rare but do happen. We did lose power for a whole week over 10 years ago. Likely I'll never have to open this Mr Heater box but better have it ready as an option. Maybe I should open it and test it before I have to use it. laugh out loud

I don't want to be overly cautious but also don't want to under estimate it. I will compromise by leaving the room door crack open and see if "low" is good enough. Want to extend the propane too in case the power go out for a super long time. Hell, with all the crazy push for electric vehicle likely the dam electric emergency vehicle will need help themselves.

What oxygen sensor do people use?

I look up all the sensors and seem everyone just assume they work. I am looking for one that actually tested and actually work.

Every situation is different. The room we used it in stayed warm for a while, and not having the room too warm minimized the heat transfer to outside, meaning even less propane used. I'd recommend this for extended power outages where propane might be harder to get than usual. Again, that would be a very specific case that's really uncommon where I am

Now that I have electric blankets I'll likely just run an extension cord and supplement with that. I measured and both of the twin size draw about 100W each. My queen size hasn't come in yet, but I'd imagine that it will use very little fuel to keep us more comfortable. I usually run the generator constantly for the fridge and freezer, so adding a couple of hundred watts won't matter too much.

Yeah, this is a great heater, We use a standard size propane tank for camping inside of a 10 x 10 Kodiak tent and wow we have to turn it off because it gets too hot works great. My wife is always cold. We camped in 20° weather by a river and had to turn it off even at the low setting because it was too hot but we have a great tent too. $74 is good price
