wiring bottle heater question
wiring bottle heater question I've been reading that I should use a relay to wire my bottle heater like in this picture here.

However, I can't see what difference it would make just wiring it like this (please excuse the pathetic artwork).

Not all heaters are the same but most pull a good amount of amps.
Our Brand X heater Specs
13.8 Volts, 300 Watts, 21.74 Amps
Nitrous Outlet heater
225 Watts, 13 Volts, 17.31 Amps.
I would use a realy before you burn something up
Hope this helps

A relay is not needed if you use a switch rated for more than 20 amps. You can find such switches at most hardware stores or Radio Shack. A 20-amp switch might be larger than you want. If you want to use a minature toggle switch then you need a relay to handle the current. You also must use wire rated for more than 20 amps. The entire path from the battery to the heater and back to ground should be 14 guage minimum, preferably 12 guage.

thanks guys. The problem is the power drop under the dash of my car can't handle the current of the heater. I was trying to avoid excessive wiring but it looks like the relay setup is the way to go.
