Ondol


It is getting a bit chilly here so I decided to make sure the heat works. Korean's generally heat with an underfloor hot water system called an Ondol. This is mine. There are no less than six valves: main inlet and outlet valves and four "zones." There is only one thermostat, in the living room, so the zones are basically heat or no heat. They are not labeled so it is a matter of turning them off or on and seeing which floors get warm. I just tested it to make sure it worked (it's not really cold yet in the apartment).
From what I've seen most apartments have their own boilers for the Ondol and domestic hot water. Mine does not. I'm guessing there's one for the building somewhere.
I did experience Ondol heating when I interviewed for the job in March. Quite pleasant -- beats the heck out of the forced air heat pump system I had back in the states for comfort at least.
