So I went out and bought a black maximus reflux still from my local home brewer store and ran it for the first time on Sunday. With it boiling away the temperature would only peak at 64 degrees but was steady. Not quite sure what to do I ran it anyway and rang the guy in the shop on Monday. He made a phonecall and he came back to me and said as long as it stabilized it should be fine. Not quite sure if I am happy with this answer as it should have sat at around 78 degrees.
What should I do?
