1The radiator in the living room was making a strange noise, so I called a plumber to fix it.
2She turned up the thermostat to warm the house, but the radiator in her bedroom remained cold.
3In the winter, the radiator is the warmest place in the house to dry wet socks.
4The old house had a beautiful cast-iron radiator that still worked perfectly after a hundred years.
5To save energy, they decided to install a new, more efficient radiator system in their home.
