Works great but...

This heat wrap worked fine but needs to be paired with a more appropriate variable heat control than the one suggested. Fortunately I had a control that worked fine.

Great product for cold basements

I purchased this warmer because I was going to be fermenting my wine in the basement. Since I live in a cold climate area, the basement is always colder than the rest of the house. With this warmer I was able to keep the wine at the proper fermenting temp. Very happy with the results. Using it again on a second batch of wine. I would have not been able to keep the wine at the proper temp without this product. Would recommend to anyone living in a colder climate.


Works great for a cold basement

Love my FermoTemps

I own 3 of them and, paired with a temp controller and thermowell, could not imagine brewing without them.

It is a great product. It keeps the Bid bubble and the Carboy at a 72-76 temp. I used it in my basement were the temp is typically this time of the year 40-50 degrees
