I'm thinking MRMOFO is not from the States. TR check into getting yourself a GFCI, ground fault circuit interrupter. Probably run you about $20. Not the 6 way cord strips with the surge protector, that protects BEFORE the unit, you need to protect yourself AFTER the plug. You can get a GFCI for cheap and wire it directly into the socket, you probably have them already in your bathroom. It's those sockets that have a "test" and "reset" button. They also produce them as a plug in style that you plug into the wall and then plug your 6 way surge protector in. By code we have to plug in everything into portable GFCI's at a construction site.
They work by measuring the amperage going out one line and returning through the other line. If there is a 5 micro amp change, I forget the .00005 type number, it automatically trips. An 8 micro amp surge can stop a heart. Basically they trip before you do.
All aquarists should have GFCI's on all of their equipment since as we know, our entire tank can be a conductor at any moment. Your fish will not get shocked swimming in the water as they are not grounded. As soon as you place your hand into the tank, a ground is made and you and your tank are now cooking. A GFCI will instantly prevent that. A hardwired GFCI socket is better then a plug in model. Most of the plugins are made so that you physically have to push the reset button to turn them on. This is to make sure the unit works each and everytime you use it, this is not a defect but a built in safety device. Unfortunately for those that use this type on their tank you will have problems with them. If for any reason there is the slightest burp in your homes power supply, a 5 min brown out, a slight surge, an hour long black out due to construction, anything that interrupts the power will leave the GFCI in the tripped position until you reset it. Wouldn't you rather have in in wall socket that will automatically continue to run when the power is restored?
TR it sounds like the seal on your heater went bad. It is a very common occurence, hence why I do not use bulb type heaters.
