Maintaining constant temperature during fermentation

[Llanbrewer]

standing the FV off the bottom on a couple of bricks will help keep the tap from pressure, and you dont need much of the FV exposed to the warm water, think about the sort of heating surface area a belt or base pad actually expose the FV to.

The only snag is that if you are using an aquarium heater, then it needs to have the heating element completely immersed, as otherwise (and this is an educated guess on my part) it will overheat, as the thermostat component is at the top end of it.

There is a compromise to be had, because the heater can be angled, so that it is all covered. I would however want it to be as low in the water as possible, so that there is an even, strong convection current to spread the heat through the water bath.

Yes i assume you would sit the heater between the bricks to heat from the bottom up.

Thanks for your replies - really helpful.

Stupid question :-? Can you use the trug / water / aquarium heater method if you have a tap on your FV that will be submerged in the water? Is there a risk the water will seep into the FV and spoil the brew?

My coopers FV has a tap. I use it as a no chill cube and to help chill things to 75Cish quicker if I'm doing a 0min addition I put it in a trug and fill the trug with cold water. I usually leave my FV cube for 24hrs-48hrs with the tap submergerd under water and never had a problem so far
