For residential heat, steam was used less than hot water, but both systems are easily repairable. Modern radiators, flatter and updated in appearance, are readily available today; many are made by Runtal, which specializes in wall-mounted flat steel panels. Traditionally, radiators were hidden under wood or metal covers, a practice still widely
Air coolers can be an ideal solution for miniature custom computers and desktops that require additional cooling beyond stock model coolers. Cons. Air coolers are not small. A typical aftermarket air cooler is quite large, in comparison to water cooling options. This means that these radiators may not fit comfortably in every PC case. With two ports open to avoid vapor lock, fill the radiator about half full of hot tap water. (You can use heated distilled water for these steps also to skip the end flush needed if tap water is used.) Plug both ports and shake the radiator vigorously for 3-4 minutes. Remove the plugs and drain it into your container.I had an automotive radiator ( '04 ford Taurus ) ontop of the sink, with a garden hose clamped on the spigot . The other end of the hose was inserted into the Radiator , and pushed the water up through the radiator and out the top at the opposite end where it drained into a bucket which i used to water plants .
