<p>An electric-powered space heater surrenders heat of compression. The assembly consists of a pump (7) delivering oil (4) through a tube (5) to a jet (10). The assembly further has a heat exchanger (20) surrendering heat from the oil. The assembly further has a tank (2) from which oil is delivered to the jet (10), and to which oil is subsequently recovered. The heat exchanger is positioned under the oil surface in the container.</p> |
