A method for making a thin, self-supporting disc from a substance, such as hydrogen, which is a gas at room temperature said disc being eventually located in a vacuum. A metal member is provided which defines a hole having a diameter small enough that at a sufficiently low temperature a ...
The boiler works in a similar way to condensing gas boilers – the water is heated as it’s passed through the boiler’s heating element (similar to a kettle) and then distributed directly to the heating system while hot water is sent either on-demand to taps and showers (combi) or stor...
