For instance, turn the temperature from 70 °F (21 °C) to 68 °F (20 °C).
These self-regulating valves allow you to control the temperature of each room by adjusting the amount of hot water goes to the radiator.
If you want to warm a small space only, a personal heater may be more effective than heating the whole home with a furnace. Choose a radiant heater, which are more energy-efficient than other models.
However, if you adjust a radiator valve to lower the temperature of a specific room, you can close the door to that room to prevent cooler air from leaking into warmer rooms.
Be sure to check the care tag on your clothing items to make sure washing them in cool water won’t damage the fabric.
