if i could post an audio file I would and you would hear the sound of steam! may not sound like it but steam is a glorious thing. we got the boiler fired up today and chugging along nicely on biodiesel; seemed very efficient too. this was a major step that needed to happen so we can brew this week so I am so glad it went well. David is now running hot water through the brewhouse and giving it a long overdue cleaning. can I get a “hell yeah!”????
