Re: [Biofuel] free inline fuel heater?
Dipstick engine heaters, are not a good way of heating an engine in winter. These heaters can cook ( overheat ) the oil right next to the heater, and leave the rest of the oil cold, depending on the way the engine is made and the fact that oil does not freely circulate as well as coolant does.

Re: [Biofuel] free inline fuel heater?
Hi Teo ; Now, if I plug them in to the 220V plugs, I know that they will give twice the heat. Power = Voltage squared / Resistance If you double the voltage the power will be 4 times higher. The heater will probably burn out quickly. Two in series would disspiate twice the power (each one dissipating its normal power) and would work fine. Best Regards, Peter G. Thailand __ Yahoo!

Re: [Biofuel] free inline fuel heater?
I just purchased some dipstick engine heaters. But I live in europe and they came from america, so they are 120V. Now, if I plug them in to the 220V plugs, I know that they will give twice the heat. What I want to know is that does the heat dissipate off these things fast enough for it not to burn. And it should have some kind of overheat prevention mechanism could this also work with 220V. Does anybody have any experience Thank you in advance.

Re: [Biofuel] free inline fuel heater?
Don't guess I'd try running a 120V heating element on 220V, but if there was a way to use two at a time, I'd wire both in series, and distribute the voltage between the two... doug swanson Teoman Naskali wrote: I just purchased some dipstick engine heaters.

Re: [Biofuel] free inline fuel heater?
Yeah, run two of them in series. These are pretty dumb heaters, and I doubt they have any overheat protection. Maybe a thermal fuse if you're lucky. Running them at four times the rated power might get them too hot, even if they were submerged in liquid. They won't care about the 50Hz vs 60Hz though.

Re: [Biofuel] free inline fuel heater?
Not twice the heat! More like 3.36 fold increase. Rearrange the formulas describing Ohm's Law and you will see that for a given load (dipstick heater) increasing the voltage from 120v to 220v will increase the power dissipation (heat given off) as follows: (220/120)^2 = 3.361... The simple explanation is that power is proportional to both current and voltage, both of which are increased when voltage is increased. I would guess that running at 220v will decrease heater life span, perhaps dramatically. Hope this helps. Good luck.
