Abstract: A distributed heating network comprising a plurality of individual heat pumps. Each heat pump is individually coupled to a common heat source of the network, the common heat source of the network comprising a liquid loop within the network, the liquid of the loop being maintained at close to ambient temperature through active heat management of the common heat source. The common heat source is further coupled to at least one energy source. A controller is configure to thermally decouple the energy source from the heat.

Abstract: An apparatus for simulating flames includes a light source, a viewing screen capable of diffusing and transmitting light, a rear reflector disposed behind the viewing screen, and a light producer for producing moving beams of light. The light source is disposed below the reflector and behind the viewing screen. The light producer is disposed in front of the light source and below the screen and light from the light source is reflected by the light producer onto the reflector and is reflected by the reflector onto the screen to produce a perceptible image viewable on the screen.

Abstract: A moveable or relocatable structure for providing an optical effect includes casing and an apparatus for providing an optical effect mounted in the casing. The apparatus is preferably a flame effect fire. The apparatus is mounted in an aperture of the casing and a gap is defined between the apparatus and the casing front wall to define an air flow path for entry of air into the apparatus, for example to supply a heater. A frame is provided in front of the apparatus to shield the gap from the normal view of a user. The frame is spaced forwardly from the apparatus and the casing front wall to allow an air flow path between the frame and the casing front wall which communicates with the gap defined between the apparatus and the casing front wall.
