Hydronics - Wikipedia

Single-pipe steam[ edit ]

Single-pipe steam radiator

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...

You have a sealed system. Water expands when heated, so the excess needs somewhere temporary to go (unless you want an exploding rad). The expansion vessel is split in two, divided by a rubber diaphragm. On one side is air, which is pressurised to roughly the system's working pressure using a pump (bike or car...
