Faster, hotter cab heat

[Archive]

The other day I decided the long, steel lines going from the front of the head to the heater core were radiating a lot of valuable heat. I went to the hardware store, & bought a length of foam pipe insualtion & a package of nylon ties. I cut & trimmed them to fit both lines with a pocket knife & put them on in about ten minutes. About the same time the weather here in Kansas moderated a little, but it seems like the heater wakes up a little quicker, and feels a little warmer. These exposed pipes are a real heat sink, especially with the turbulance kicked up under the hood by the fan. I'm surprised these arn't wrapped or insulated from the factory.

Dennis,good idea. I'd keep a eye on the insulation though,it can get awfully hot under there. The foam pipe insulation I've seen(gray/black stuff) is only rated to 200°before it starts melting.

You need to take the temp of the heater air outlet with and without the insulation to document results. Cool idea!

Souds like a good idea and potentially helpful up here in the North. I will attempt to "banddage" the lines with self adhesive, foil backed insulation sold at my local hardware store and the pipes will have a chrome appearance.
