Which one?

Steam or
hot water?

Older homes & buildings

Steam

  • The boiler boils water. Steam rises up the pipes to the radiators, and the water runs back down.
  • You’ll hear it working: clanks and hisses.
  • Common in older houses and buildings.

Most new boilers

Hot water

  • The boiler heats water and a pump pushes it through radiators or baseboard.
  • Quieter.
  • Today’s high-efficiency boilers are this kind.

Not sure which you have?

Look for a little glass tube on the side of the boiler with water in it. If it’s there, you have steam.
