A British company has invented a boiler that generates electricity as well as heat

In a traditional boiler, gas is burned to heat water, which then passes through the home’s pipes and radiators.
The Flow boiler instead uses the gas to heat a high-pressure liquid coolant that is sealed inside the system. The vapour created then moves through a dynamo called a “scroll expander,” which spins and acts as a mini electric generator.
The hot vapor then moves through a heat exchanger, heating up the hot water for the house. The vapor returns to the boiler as the hot water is pumped around the house.
