Just keep in mind that a 1500w element running at 110 is only putting out 1/4th the wattage = 375W. This will definitely factor into how long it will take to push temps. Might consider a drop in heatstick if you don't use a propane burner for pre-heat.
Goat Mountain Brewery (GMB)
A 10 Gal all-eletric nanobrewery nestled in the foothills of the cascades. My own slice of paradise.
