That's a shame. I'll have to go through ALL of my docs on ALL of my repos and change suppliers - again. 
There's nothing about BrewPi Remix that will make that unsafe. Assuming your high voltage wiring is all legit, it will maintain any temp you set. Remember you will have to change the max temp to get there - out of the box it's set at 82 IIRC.is it safe to heat to upwards of 100F (say for saison/kviek strains)?
