There could be a short in the wiring that is causing the breaker/fuse to trip. Or, perhaps you need a fuse with a higher rating than the one that's in there now. The fuse would not be located in the unit itself, but in your breaker/fuse box for the house. The best advice is to let an electrician sort it out. I've never seen a hot water unit like this in the states. Do you have one of these units on the kitchen sink? It seems economical to only heat the water that you're using instead of keeping a tank of water heated at all times, but it must put an extreme load on the wiring when hot water is suddenly required.

They're used when the water pressure (as provided by gravity) isn't sufficient to give a powerful shower - a pump increases the water pressure. The dial on the front is the hot/cold blend.

There's (usually) no heating going on, just blending and pressurising.

In America, shower pressurizes you!
