Electric demist heater?
Hi frends,
Is electric demist heater (something like the one solt by nfauto) a good thing?
I do not want to complicate my life with radiator,fans ,heater ducting, water valve etc.
So what do you think? Is electric an alternative?
Sorry about my English

I had one years ago and it was utterly useless. Maybe the nfauto one is better.
Remember you get KILOWATTS of heat from a car heater - that would translate to hundreds of amps at 12V!!!

Same as Bob C, had one years ago in an old moris minor, complete waste of time, and electricity. Ray
To make a car go faster, just add lightness. Colin Chapman - OR - fit a bigger engine. Chippy

NF auto do two different types. The little ones are pretty poor but if you have two it's usually deemed just about okay for SVA.
The big ceramic heaters are better but rather ackward to duct etc.
As mentioned they take a fair bit of electricity (thick cables needed) and still they won't be as good as a normal heater (which in reality just
makes use of a product of the IC engine- ie heat!!)... Seems a shame to be getting rid of heat at one end of the car and then burning more petrol to
create electricity to make more heat at the other!!!
Personally for a lightweight heater I'm using an oil cooler (in the coolant circuit), an ali box and a cheap RC ducted fan motor / fan (I got a
fan blower of a Porsche 911 but its f'ing heavy!!!).... Total cost about 35 quid....
But then that's partially cos my alternators a bit puny anyway....

Have heard they're a bit wimpy. Some use them in addition to engine heating so you get some heat as soon as you turn the key. Not very locost
though, nice idea for a bigger project though. One day I'l do my M5 engined cobra hard top...

I used a couple of 12v hairdryers which passed SVA and did clear the screen. This solution was mainly to give me room under the bonnet.
