Thanks again for the help
only going to use first FV then bottle.
Questions
1. What is crash cooling and how is it done?.
2. A mate as given me the old (guess how old) boots immersion heater from an old brew kit. It still gets warm but not sure if i should use it. The brew will be in the garage so suspect will need some kind of heating
. Looks like the Electrim 74Immersion heater

Thanks again for the advice.
