When you take down your basement wall, you will find a heater duct laying on the floor back there. Take this duct and route it down the hole where your plumbing goes to the holding tanks. Point it down and aft as far as you can. This will put heat into your underbelly towards your dump valves to help prevent freezing valves, tanks and plumbing.
Take Gorilla tape and seal up any holes around your frame. This will stop Drafts and help keep you warmer.

None of mine were just laying. I took the time to make sure they were connected securely. I do get heat out of the vent in the storage bay.

This was the culprit. It was rustier when we removed it. This is after a clean up attempt.

Yep, I've seen that before. If it happened once...guess what. Buy another one and keep it with you for the next time. You can reduce down time when it matters.

I had my furnace start up and then not fire. I replaced the auto resetting fuse with standard fuse and this corrected the issue. The fuse would trip and then reset during troubling shooting. Stand fuse holds longer to allow the inrush current to lower long enough.
