Pool Pump for Jacketed Base?

Not the right pump. should work for cooling water on a still or FFE.

Here’s your $70

Pair it with whatever size tankless water heater you need to achieve your desired evap rate. (The maths are around here somewhere). 5kW probably isn’t a bad place to start. But I’ve been evaporating ethanol not butane recently, so that guess is not as informed as it once was.

There is probably a 1k word substitute with all the plumbing shown on In hot water...

There will also be links to a couple of other relevant threads…


I’ve also just made a “tankless water heater” out of a 10” length of 2” black gas pipe and a handful of fittings from home despot.

A tee, a couple of 3/4” barb adapters and the appropriate bushings or reducers.

A 1500W (or 4500W if you do 220V) water heater element will thread into npt. and a water heater thermostat will regulate in the correct temp range.

If your sous vide wasn’t up for the task, you’ll want to step up to 220V heating.
