Block heater amps

[Monte22]

Hello,
Does anyone know the amount of amps the block heater puts out? I am burning up the timers I am using. I can't find it in any search.
Thank You

Can't say about the amp rating but....
If you are burning up any thing that is rated to 15amps(standard outlet rating) or more than you have a problem with the block heater or the quality of the timer. If it is a short someplace then it should be tripping the breaker.
I have been using the same timer for about three years and I use two heaters and a battery charger. Also the length and size of extension cord will play into things.
Hope this helps....

Standard freeze plug block heaters are usually listed as 600 watts or it will draw about 5-6 amps...... I have used a heavy duty - 15 amp timer without problems... a standard lighting timer will not last very long - the load is over 600 watts to start, and then settles down as it reaches operating temp.

Hope this helps.....

A buddy just gave me one for my 6.5 and it says 1000 watts on it.

To calculate the amps for the block heaters, just use the above formula. The 1000W rating sounds about right, as I was looking at some blockheater by an aftermarket supplier that listed 900W.

The Factory block heater is 600 watts, Which will pull around 5 amps with a good 120 volt source. If you have lower voltage at your house, like 110 (which is not uncommon) and long drop cord, which will drop the voltage down to prolly 106-108 then your 600 watt heater is now pulling around 6 amps. Add a cheap light timer to that and you voltage has dropped again. Most small light timers are only good for about 4 amps constant draw.
