They're basically just the cement walls that make the foundation. The washer is down in the basement, so yes, the area is heated.

Well, maybe they aren't quite 1/8" away. I'm not there ATM to measure, but we've already noticed them getting close to freezing this year. Last time, we were able to keep the water running during the night, but we caught it in time.

One way or another, they're getting pretty cold, and so far outside temps haven't dropped below the teens. Once things get into single digits, I have a feeling that there might be some trouble if we don't do something.

New home, and the cold water pipes going to the washing machine are about 1/8" away from an uninsulated exterior wall. We haven't had any major freezes yet, and I'm trying to figure out the best way of insulating these pipes to avoid any potential problems this winter.

I was wondering if putting a few sheets of insulation on the outside of the house might help. Since we are planning to re-side the place next summer, I was thinking that just adding some insulation now might solve our current pipe issue while also saving a bit of work down the road.

Thoughts? Any other suggestions about ways to keep the pipes insulated?

We have a decent amount of moisture in the basement, and aside from dehumidifiers, I was debating about other potential ways to filter/cleanse the air:

• First, I was thinking about adding a UV light somewhere on the furnace. Problem is, I'm not sure where the best place to put it would be! I've been reading some sources that suggest pointing it at the evaporator coil, but since I'm actually more concerned with filtering heated air, I'm not sure. Any suggestions? What about pointing it directly at the intake filter?

• I'm also debating adding a layer of activated carbon to the intake filter. Think this would help with mold/cats/etc.? By adding an additional layer to the filter, should I be worried about reducing the amount of air output by the furnace?

Thanks!
