Ordered this heater last month and just now getting around to installing it. These suitcase heaters are far more simple to install than the versions that are more scattered. I bought the latter last fall and it works very well. We burn wood and this prevents those cold mornings when the wood plays out during the night. Makes Winter far more tolerable. Suitcase variety primes faster (I didn't do the prime bit). I just filled it up and in about 10 minutes it picked up the fuel and got hot quickly. Liked them so well, I ordered two more for the shop buildings. Heads up...I thought I'd been shorted an air intake hose and used rubber hose from a car instead. It worked well. While hooking up the indoor heat tube, I found the little intake hose hidden inside. All is well. I have a backup hose now. Cannot attest to the longevity of these units but first impressions are positive.
