Skargards Electric frost protector

A wood-fired hot tub can withstand minor frost of a few degrees Celsius. If temperatures drop well below freezing, we would recommend either draining the hot tub or using a filter system in combination with this frost protector. This handy frost protector acts as an electric heating element. This will release heat into the water, preventing it from freezing.  

This Skargards frost protector can also be added to TICRA wood-fired hot tubs.
