State lawmakers move to change code for 'green' furnaces
After a cold winter in which high-efficiency heating units, some called "green" or "90 percent plus," installed in thousands of North Carolina homes froze up, lawmakers are moving quickly to update the building code.Posted — Updated
The energy-efficient furnaces create more condensation which, when routed outside of the home, froze in the cold, causing the heaters to shut down. Builders suggested that homeowners keep their condensation pipes from freezing by pouring hot water on the pipes, using a lamp to thaw them or even wrapping them in beach towels.
The bill has yet to pass the House.
