we put in a new laundry room with the pipes & drains in a 2ft wide by 9ft long over hang area. (see photo). we wrapped the pipes & drains in pipe wrap & used fiberglass insulation in the rest of the area & even put a rigid insulation between the ground & the overhang.... it still froze. not sure what to do next ?? some things i thought of as a next step are:
.. is wrapping the pipes with a heat tape an option? if so, is there a fire hazard ?
.. we may be able to run a new heat duct off an existing duct to the area that contains the pipes & drains. i know nothing about heating systems. if i run a new duct into such a small area (2x2x9) cause problems??
this is a very frustrating situation we have gotten into so any input you can provide us will be greatly appreciated. thanks!!
