I hope to plan next week, but highs will be below freezing. I don't want to bring by 5 gallons of boiling wort inside my house and down stairs to hook up the wort chiller to the laundry room sink. I have done it before and found it to be a PITA. So, I still want to chill my wort outside. Will the wort chiller work and water not freeze in the garden hose if the air temp is about 20 degrees?
