    • Great back up when the poop hits the fan
Number of Items: 2
Power failed and whole house generator pooped out. This heater saved my butt as it was 7° with -20° wind chill. Between two small generators and this heater we kept the house above freezing. Worked for days on a single 20lbs tank as roads were solid ice for days as well. Good back up safty plan to keep on hand. Amazon also sells the CO1 sensor and LP GAS LEAK sensor as well as the gas line and filter needed all at good prices! ... show more

I bought this as an emergency backup to keep the heater warm in case we ever have a power outage. This is gonna work out perfectly to keep all the plumbing warm during those cold snaps if we ever lose power. It actually saved me from buying a second generator They are super easy to operate and seem to be very safe ... show more

Mr. Heater is a life saver if you do not have a back up generator. Buy some propane tanks and the adaptor for Mr. Heater and you won't freeze for a couple of days. Perfect for rural locations where there is not much population. Follow your weather channel if you can because this will help your plan of attack. Be prepared if you are not in a city. ... show more

    • No tanks and/or fuel included.
Number of Items: 2
I purchased the twin pack. Nowhere in the description of the unit does it state that it does not come with propane tanks. This would be nice to know before purchasing it. Also, you need to know which type of propane tank it takes the POL type or the QCC customers need to know in advance that they need to buy propane and or bottles so they have the ability to use this heater as a heat source right away When it states that the item cannot be returned because it’s a hazardous content, that kind of gives you the impression that it’s being shipped with fuel or something hazardous. I see no reason the consumer should not be able to return these basic dry heaters when they arrive with no propane tanks and no warning that you need to buy the tanks for the heater. ... show more
