1.2.14 Purge radiators at the beginning of the heating season

1.2.14 Purge radiators at the beginning of the heating season

Description

One of the most common causes of poor performance of a hot water radiator is air trapped in the system. Over time, the repeated heating and then cooling back down of the water in the system causes air to be released from the water. And since air does not conduct heat as well as water, this trapped air reduces the energy efficiency of the radiator system. To eliminate the air, it should be purged out of the radiators at the beginning of the heating season, and then whenever they seem to not be heated as much as normal.

 

Benefits

  • Easy to implement

     

  • Depending on what type of radiator, it may be possible to automate the process of bleeding the radiators by using an auto vent

     

  • Obtain the maximum efficiency  of the unit

     

Limitations

  • Occupant acceptance

     

  • Operation and Maintenance (O&M) staff size, skill level, and budget need to be considered

     

Economic assessment

Zero or low investment. 5% cost savings.
