1.3.3 Adding or repairing DHW distribution systems

Description

It is recommended to properly insulate pipes to limit heat losses, as well as to install the boiler/accumulator as close as possible to the consumption end points to limit the losses that occur through the walls of the pipes. The insulation normally used for pipes where the water circulates are moulds of elastomeric foam and rock wool, and should be installed both on supply and return pipes.

Benefits

  • A good insulation of the pipes reduces the thermal losses in around 50%

Limitations

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

  • Just applicable for buildings with centralized HVAC system

Economic assessment

Initial investment: low, but it depends on each installation
