How to Drain a Home Radiator

时间:2014-05-02 20:01来源:未知 作者:chinabeizhu
  It is necessary to drain a home radiator when you have to change it or take a malfunctioning one
in for service. A radiant heating system works by circulating hot water through a network of pipes
and radiators in your house. As the water passes through the radiator, it heats up the radiator fins,
which radiates warm to the surrounding air. The water is then passed back to the boiler to be reheated
and start the cycle again.
1. Turn off the power for the heater. You can do this either at the heater or at the circuit breaker
    that controls the heating power.
2. To protect the floor, place a dropcloth or sheet of plastic underneath the radiator you will be draining.
3. Shut off the inlet valves at either end of the heater. In most installations, one of these will be a
    thermostat-type knob that you can turn by hand, while the other will have to be closed with a
    wrench or pliers.
4. Open the bleed screw at the top of the radiator with the bleed wrench.
5. Locate the drain valve for the radiator. In most cases, the drain valve will be installed on either
    the inlet or outlet valve. It will be mounted horizontally rather than vertically like the inlet or outlet
    valve. Place a bowl or container under the valve and open it with a wrench. Allow the bowl to fill.
    Close the valve and empty the bowl when needed. If you don't have a drain valve, you can drain
    the radiator by emptying it through the union joint.
6. To drain the radiator by emptying it through the union joint, use a pair of wrenches to disconnect
    the radiator from the union joints where the radiator meets the inlet and outlet valves. Use one
    wrench to hold the valve steady while you unscrew the union joint with the other wrench. Keeping
    the valve steady helps prevent the pipes from being damaged.
7. Unscrew the radiator from any brackets holding it to the wall. Lift up on the radiator to remove.
