By means of the pump any desired velocity can beattained with a corresponding regulation of the temperature.

The Yaryan system is essentially the same as the Evans &Almirall system. It seems to differ only in minor details ofconstruction. The Osborne system differs in that the exhaust steam iscirculated to a heater located in the building to be warmed;no pump for circulating water is used ; the transfer of heatfrom the exhaust steam causes a circulation of water throughthe heater and t
