e-Vaporator

Thanks Jeff.:cool:

Eric,

I find your design and experimentation fascinating. Well done.

I hope there's more discussion in this thread. :D

If you are using 120 volts and a 1500 watt element I = P/E --- I= 1500/120 --- I = 12.5 amps --- 2 elements would be 25 amps

120 volt circuits use either 14/2 wire that is rated for 15 amps or 12/2 wire that is rated for 20 amps both of which are too small to handle the 25 amp load.

AWG 12 good for 20A derate at 25A melts in half at 56A

That foam turned out to be a treat for the bees. When I skim I just fling the crud out the door. My son just hived his packaged bees and they were really enjoying the maple treat.

I've made some progress on the kitchen sink to e-Vaporator conversion, but I'll take it to its own thread. Thanks, Fyreaway, for the inspiration. There are many ways my design is not as good as yours. I won't be using it to finish syrup or warm it for bottling, because it will take at least two gallons to cover the element, but if it boils water more cheaply than propane can, it will be worth what I'm spending on it. ;D

In another hobby, where they boil liquids to separate the vapours from what remains in the pot, they use beer kegs with one or two water heater elements. Run them on 240VAC to heat up, then switch to 120VAC for a constant simmer. The foil backed bubble wrap insulation keeps the heat in the keg quite well.

A beer keg on it's side, cut in half or slightly higher, would make a nice sized sap e-boiler without the major fabrication cost.

Something I'll ponder for next Spring.

bkeith, what other hobby are you talking about?:rolleyes::D

The fun part is you don't really know that anything you do will be less than what I've done. My design has a V-bottom that works pretty well. A flat bottom sink might very well be better. Without playing around with the options we would never know. Using the sink to boil off the bulk of the water and then finish with what you're familiar with sounds like a good plan. I'll be watching for your thread on the new build.
