CHC heat pump centre

Benefits of a buffer cylinder in a CHC heat pump centre:

• Reliable supply of energy to defrost the evaporator
• Great DHW convenience and better reliability thanks to the large volume of heating water

These applications can do without a buffer cylinder in the CHC heat pump centre:

• Systems in which all energy required for defrosting is provided by a further system
• On-site integration of a large-volume WOLF buffer cylinders to:
  1. Cover heat pump downtimes (e.g.: utility company power-off periods)
  2. Continued provision of heating warmth while heating DHW

Benefits / drawbacks of series buffer cylinders:

• Integrated overflow valve ensures reliable compliance with the minimum water circulation volume
• Reliable supply of defrosting energy
• No additional circulation pump required in the secondary circuit
• Higher overall efficiency than separation cylinders
• Only possible in systems with a heating circuit

Benefits / drawbacks of separation buffer cylinders:

• Hydraulic separation ensures reliable compliance with the minimum water circulation volume
• Reliable supply of defrosting energy
• Can cope with suboptimal layouts no matter what happens downstream of the system.
• Can also be used in systems with multiple heating circuits
• Additional circulation pumps needed in the heating circuits
