Demand Duo Integrated Floor Hot Water System

Combines the benefits of continuous flow and storage—high output and minimal storage loss without limiting peak flow rate

  • Cost effective installation with pre-constructed skids
  • Connect multiple skids in parallel for larger systems
  • Compatible with circulating ring mains
  • Cost effective and easier to maintain than boiler systems

Ideal for commercial applications where the total water drawn during the day's peak is known, but the rate of water use varies. For example; central hot water systems for hotels, motels, and apartment blocks.

Hard or aggressive water will need to be treated in order to use this system. If in doubt please test before use.
