I planned to buy a Reznor, was doing research and came across the Sterling unit heater. I decided to go with the Sterling since it had all the same features as the reznor and was a little less expensive. I am pleased with the heater, its quieter than I expected and does the job. I went with the sealed combustion and concentric kit. Those two kits are overpriced in my opinion and come with more parts than I needed.
