Heat Cable

Postby biovindiesel » Sun Nov 23, 2008 5:13 pm

Has anyone any experience with using Heat Cables on a veggie conversion? My thought is to run this from the FPHE/hot filter down the lines to the veggie tank.

This would not be in use while driving. I'd have this plug in alongside the block-heater so as to expedite the thawing process of the crankcase and conversion lines.

The system is heated with a FPHE/coolant lines down to the aux tank and has neoprene insulation, VW 1.6t. I live in North FL so it should be fine here, but I'm curious if a setup like this would last long up in the North. I'm planning a trip up to DC in January and wherever the wind blows from there.

I have not done this but it might be a good idea if the heat cable was under the insulation. I assume you're thinking of the heat cables used to freeze protect pipes. Wrapping a preheater pad around the fuel filter and a 'battery blanket' preheater across the injectors helps to preheat the engine and fuel system to achieve quicker switch-over times.

Which heat cables are you considering?
Watch that the temps. do NOT exceed @ 300F or you may damage or burn the neoprene.

It wouldn't be worth it since you shouldn't switch to VO until the coolant is warmed up. Heat tape would have little to no effect on coolant temps. A block heater and blocking part of the radiator is much more effective.

Thanks guys.

I did some searching and I'm going to forgo the heat cables idea and make a winter front out of some neoprene sheet. Any ideas as to what I should spraypaint on the front of it? I figured I'd make a stencil for it.

I don’t mean to poo-poo this whole batman thing but why neoprene?

Cardboard or corrugated acrylic sheeting (i.e. recycled election signs) is cheaper and equally as effective.

I already have the neo.
Also, I want something that will look nice. Not just some cardboard or Obama '08 though that might be cool.

This is what a winterfront is supposed to be like.

Here is a good one too.

I don't like most of those winter fronts, they look like a diaper on the front of the truck. The best ones you can't even see at all, for mine I bolted a piece of scrap black 1/4" plastic on the back side of my grill and its not visible.

My 'winter front' is a floor mat that slides down between the rad and the AC coil. I can easily adjust the amount that's blocked off from 0 to 100%. Does not show from outside the truck, works great.

I'm still a kid so mine is going to have batman on it.

Screw you oldies. My VW emblem does look nice though, maybe I will put it behind the grill if it looks bad.
