I'm wondering exactly how hot the outside of a block heater is expected to get. I realize that it's a heater and it's going to get hot during operation, but I think mine may be heating up a bit excessively.
Several months ago, I installed this Zerostart block heater in my K24 swapped Honda Civic and although it works well, I noticed that the exterior brass piece around the heating element and electrical connection gets extremely hot within seconds of plugging it in to the point of instantly boiling drops of water off the outside of it, which seems a bit excessive to me.
My concern is that if the outside of it is getting hot enough to boil water, I don't see what would stop the coolant inside from getting hot enough to boil and create pockets of steam, which would obviously be bad. Is this a concern?
Here is what the block heater I installed looks like in case anyone is wondering.
Thanks a lot for any input as always!
