  • What Size Heat Pump Do I Need?

    A ground source heat pump extracts heat from the ground with a network of pipes buried under the surface. These pipes can either be installed as horizontal or vertical loop systems. Vertical ground loop systems are drilled deep down into the ground. Often as far down as 100 metres where temperatures are at a consistent 10-15C all year-round.

  • Steam locomotive - Wikipedia

    2021-9-6 · A steam locomotive is a rail vehicle that provides the force to move itself and other vehicles by means of the expansion of steam.: 80 It is fuelled by burning combustible material (usually coal, oil or – now rare – wood) to heat water in the locomotive's boiler to the point when it becomes gaseous and its volume increases 1700 times. Functionally, it is a steam engine on wheels.
