• The heating radiator was invented by Franz San Galli in 1855, a Prussian-born Russian businessman living in St. Petersburg.

• Energy Star recommends placing heat-resistant reflectors between radiators and exterior walls to retain heat in the room

• Types

  • Hot water - These use convection of hot-water to circulate heat
  • Steam - these have steam run through pipes. More efficient for large buildings. However, the cause steam-hammering. The bang is created when some of the steam condenses in the pipe, which gets taken up by high pressure steam and hurled at high velocity through the pipe.

• In R:Russia, central heating is setup by the government. Individual buildings or units have no control.

• Just like water and gas, heat is taken care of by the government and runs from October to May.

• There are about 172 heating plants spanning Moscow - about one furnace for every 58000 people

• Individual thermostats are not a thing, and it can take up to 12 hours for any temperature change to go into effect all over the city
