FastFerment Conical Fermenter Heat

[GDGeorge]

Hi Folks,

Up to now I've use aquarium heaters successfully in my buckets when needed. This past year I acquired a FFT conical fermenter on Freecycle. It worked well the times I've used it, but the house is chilly in the winter. I've got a couple 17.5W (120V, I'm in the US) heat mats and I'm thinking that one will maintain temp if I put a foam jacket over the fermenter. I've got an Inkbird controller if needs be.

Has anyone tried this with a conical? Has anyone had issues with putting insulation over the mat?

Thanks,
Jerry
