I was looking on the inductionsite.com and they have calculations to compare to a propane/natural gas burner. At 1.4kW you are equivalent to only about 10,000btu when taking efficiency into account. Not a lot of juice to keep 6gal rolling. You can buy much more powerful models, but the price is much more powerful too! Plus they usually draw 200-240V so you would need to probably do some rewiring in the house. If i had the money, which I unfortunately don't, I drop the money on a really powerful model....lots of nice features with induction cookers. Not for your average poor brewer though.
