I like these heaters so much, this is now the 3rd one I've gotten from the same vendor. I use one @ my house for early season heater and when the wood stove isn't necessary or when it's -20F plus , I have one in my hunting camp and this one will be in my new garage when it's completed. I LOVE THESE THINGS !!!This would make one outstanding "prepper " item to have on stock too IMHO !!Both of mine have been used allot and have been very very reliable , only having to clean the glow plug on one of them once and talk about efficient,,,WOW ! They virtually sip fuel and will easily heat my whole 800sq ft cabin well into December here in VT with no issue. And that's including a partially insulated front porch.As an example I can heat my whole house when it's 15-20F degrees outside and only use maybe 3/4 of a gallon of diesel , if that, in a 24 hour period and actually, once the house it up to temp I can literally set it on 1 or 2 with the thermostat set at 22c and it stays warm and toasty . In the Fall I can get a couple- three days use out of one tank full quite easily when I just use it to take the chill off in the AM and before bed.All my ice fishing buddies that have fixed shanties, and contractor buddies, now have them too and they swear by them as well so there versatile for a ton of different situationsI highly recommend these heaters,,,they rock !
