The most basic way is using a thermocouple, it produces a small voltage (mV) when the hot junction is at a higher temperature than the cold junction.
On a bigger scale water is heated to drive turbines that are connected to generators, this is the basis of nuclear or coal fired power plants

Heat produces electricity by means of a generator.
Usually, a generator works by heating steam that operates a turbine. The steam rises on one side of the turbine, turning it either clockwise or counter-clockwise (doesn't really matter). The turbine is connected to a magnet which spins along with the turbine around a wire, which induces an electric current in the wire.

Adding heat to a gas causes it to expandm decreasing its pressure. Pressure differentials can drive a body of gas upwards. That upward push can be used to spin a turbine. That turbine can be connected to a solid state magnet embedded in a coil of electrical wires. That rotating magnet will induce a current in those wires, and hey-presto... electricity.
