60% efficiency at 1,500watts, 12,000BTU of Natural Gas. Start-up time 25 hours! 36-72 hours of power needed just for cool down if you shut it off. Grid independent not possible. This unit needs to spend allot of time getting to temp. It also needs to off load some of that heat. If you get free Natural Gas go for it, but chances are if your getting it free the sulfur content could be a little high and you will spend more to filter it out.
The Bloom design is much better both in efficiency and output.
