2. Air source heat pump - Wikipedia

   en.wikipedia.org/wiki/Air_source_heat_pump

   There, the hot refrigerant gas condenses back to a liquid and transfers the stored latent heat to the indoor air, water heating or hot water system. The indoor air or heating water is pumped across the heat exchanger by an electric pump or fan. The cool liquid refrigerant then re-enters the outdoor heat exchanger coils to begin a new cycle.

3. Hydronics - Wikipedia

   en.wikipedia.org/wiki/Hydronics

   In the oldest modern hydronic heating technology, a single-pipe steam system delivers steam to the radiators where the steam gives up its heat and is condensed back to water. The radiators and steam supply pipes are pitched so that gravity eventually takes this condensate back down through the steam supply piping to the boiler where it can once ...

6. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   The Summer Palace in St. Petersburg had an early system of hydrologic central heating. Early hot water systems were used in Ancient Rome for heating the Thermæ. [13] Another early hot water system was developed in Russia for central heating of the Summer Palace (1710–1714) of Peter the Great in Saint Petersburg. Slightly later, in 1716, came ...
