1. Unvented space heaters are more efficient than vented space heaters, because none of the heat output goes up the flue. All of the heat output (as well as the combustion gases) stay in your living room. 2. The gains in efficiency are not worth the risks to your health.
A water heater, especially an electric model, is a very simple device. Unheated water enters one side of the tank. The water is heated by a couple of electric resistance elements that extend from the side of the tank into the middle of the water. And then on demand the water exits from the other side of the tank. Unfortunately, such simplicity doesn't really extend to its installation.
