Heating, Air Conditioning, Fridge, HVAC/Frozen furnace pipe in attic

Question
Hi, I live in CT and we just built our house 3 years ago. It has been getting below zero here. We have 2 zones in our house. One in basement and other is in Attic. Our house is called Italianate so the way it was built has efficient air flowing through. The problem is, its freezing up there and furnace pipes froze, so the temperature in the upstairs is staying at 64. We purchased the heat wire but its not thawing it out completely. How do I prevent it from freezing should we build something around it to keep it warm? Any thoughts would be helpful...

Answer
Heather,

If your talking about the drain line for a condensing gas furnace, you would have to download the install guide, and see what it says about low ambient temperature locations. Also you can talk to the Dealer who installed it, or call the Technical Rep. of the brand .Have your model number available. Also the heat tape you bought may not be a high enough Watt rating to work in very cold enviorment, or you need to insulate the drain line after you install the heat tape . ( Ask the Technical Rep. if insulating the heat tape after it has been installed on the pipe and the wattage rating.) Where does the drain water terminate ? Typically the manufacture has a toll free number or a contact us  email.Your not suppose to overlap heat tape and it needs to be a certain distance from the next row, not to far or to close to each other. Your install instruction ( google it ,find a pdf file )  may also state to insulate your plastic PVC vent piping with 1/2" armaflex insulation if furnace is installed in  area  cold locations.
