I converted two TDI's: 06 Golf and 03 Jetta. Both are working fine but I was wondering if there was a way to get the cars to heat up faster other than using a TDI heater? It was suggested to try a high heat thermostat but I wasn't able to find one that was rated much higher than the stock thermostat. Thanks, Chris

What is a FPHE? I have a plug in TDI heater on both cars but only use in winter and doesn't help much for drive home from work. What is cheaper the diesel to heat up the car or the electricity to preheat the engine? Windsolar

Assuming you have a 1000 watt TDIHeater and heat for less than an hour, thats 1000 watt hours or 1 kwhr, about 20 cents these days.
Diesel will be about the same 1/10 of a gallon or 25 cents.

FPHE is a Flat Plate Heat Exchanger, the current standard for heating up the fuel with coolant.
Not sure what your PlantDrive is, but it's deficient if it doesn't have one.
Have you measured the temperature of the injection pump when fully warmed up?
Should be 150-170*F.

Thanks, my plantdrive systems are based on a vegtherm that heats the svo just before the oil hits the injectors. I also have a 10kw solar array and electricty is essentially free for me so plugging in for an hour seems the way to go. windsolar

windsolar,

That's good news on the solar powered electricity.
But you plantdrive must have some other form of fuel heating other than the vegtherm.
You should find out what it is and measure the i.p. temperature before you drive another mile!

It's a total system, Hot Fox, with Veg Therm and VO control system. works fine I was just looking for ways to decrease heat up time. Thanks, windsolar.
