For any controlled electric system (I have no interest in heatsticks, and several very good reasons why I won't use one that are irrelevant to this thread) that would take me way, way longer than I plan on living to amortize the cost of an electric brew rig. I simply could never justify it on fuel savings alone.

There are other reasons to go electric, and I'd like to, but once again, that discussion is beyond the bounds of this thread.

I'd guess I get three in (using it for heating the HLT, as well) on a 20lb tank. It's not empty at that point, but the pressure begins to wane a bit so I swap it onto the gas grill. I have four tanks that I rotate around between brand new exchange, brewery, and gas grill.

I built 2 1500 watt heat sticks to do 7.5gallon boils. Each heatstick was $40. The price of 2 burners = $100+, 2 tanks = $80+ plus fillup . So no cost to recover with heatsticks. In electric they run like 60 cents a brew. So electric can definitely be the cheapest route. I couldn't imagine the hassle of hauling propane tanks to get filled every 2-3 brews. At $16 a pop.

This just reinforced how much of a savings it really is.

Estimate 24 brews a year. Runs me at most $15 in electric With gas at least $150. 10x

Plus you can brew indoors safely and insulate your pots fully.

I brew 11.5 gallon batches in a 2-tier keggle all-grain system, and usually use around 7.5 lbs of propane per batch. That is with 90 minute boils, too...

Yeah, I do mostly 10 gal batches myself and have been wondering what it would take to splice a 1/4 in flex line off my gas meter area directly to my burner. With a shutoff valve at the meter. Would save me many Home Depot trips!

It also depends on whether you are exchanging your tanks or getting them refilled. If you are exchanging them, you are not getting a full 20# of propane, but rather anywhere from 15-17#. This would shorten your tank life also.

I place drywall around all 4 sides of the burner....brings my "to-boil" time down significantly.

A decent plumber can do that for you in no time. I was actually thinking of switching to a natural gas burner since I have the line run to my grill already. I wish I could find a natural gas burner that isn't so pricey.

Tanks are only 15lb now.
