The home brew wrap around electric heater fits around your standard fermenter to provide steady constant warmth.
Place the belt around the outside of the fermenter approximately 45mm from the bottom and adjust it to fit by carefully tightening the lead via the hole in the outer end of the belt. Do not over tighten, twist, tie or fasten in any other way.
When air temperature exceeds 20°C shift the heater belt up to approximately 150mm from the bottom and when the ambient temperature exceeds 24°C switch the heater off. This action should keep the brew at 20° to 26°C depending on ambient temperature.
