  4. Chapter 1 Range Overview & Rheem Commercial Booklet

  5. Chapter 2 - Commercial Heat Pump

  6. COMMERCIAL HEAT PUMP LAYOUTS

  7. COMMERCIAL HEAT PUMP LAYOUTS

  8. Chapter 3 - Commercial Solar

  9. Commercial Solar • Terminology • Split / Pumped / Loline • Close Coupled / Thermosiphon / Hiline • Direct / Indirect (Premier Hiline)

  10. Commercial Solar Loline

  11. Commercial Solar Loline • Pumped system • Collectors and tank are split • Fluid is pumped between collectors and tanks • Can be on same level or different levels • Direct system • Consumed water passes through the collectors • Partial frost protection • In series boost

  12. Commercial Solar Loline • 325L and 410L vitreous enamel storage tanks • Manifold tanks as required • NPT200 collector • Painted aluminium selective surface • 7 riser tubes • Good performance in all regions

  13. Commercial Solar Loline • Frost • Limited frost protection • Frost sensor strategy • Electric or gas frost heater • Secondary Solar Recirculation • Maximum solar energy use • reduces energy use • BMS output • Run and fail status

  14. Commercial Solar Premier Hiline

  15. Commercial Solar Premier Hiline • Thermosiphon system • Collectors and tank are close coupled • Fluid rises through collectors naturally to tank • Tank is always above collectors • Indirect system • Transfer fluid passes through the collectors and transfers heat to tank via heat exchanger • Full frost protection • In series or in- tank electric boost

  16. Commercial Solar Premier Hiline • 300L stainless steel tank • Manifold systems as required • 8 systems per array, multiple arrays possible • S200 collector • Steel collector • Painted selective surface • Good performance in all regions

  17. Flat Plate vs Evacuated TubeCollectors

  18. Chapter 4 EQUA-FLOW MANIFOLDING

  19. EQUA-FLOW BASICS

  20. EQUA-FLOW BASICS • Header diameters for cold/hot to be equal • Branch diameters for cold/hot to be equal • Hydraulic water flow “In one side, out the opposite” • Balanced performance per unit. Full delivery capacity from system Flow direction Out In Line Flow direction In

  21. EQUA-FLOW BASICS Flow direction Out Back to Back Flow direction In

  22. EQUA-FLOW BASICS 1 1 B 0+1+1=2 A 0

  27. EQUAFLOW PRINCIPLES IN PRACTICE

  28. COMPLICATED EQUAFLOW PRINCIPLES IN PRACTICE When designing/ inspecting complicated manifolds consideration must be given to primary loops as well as hot and cold headers

  29. EQUAFLOW PRINCIPLES IN PRACTICE

  30. COMPLICATED EQUAFLOW PRINCIPLES IN PRACTICE

  31. BRANCHES • NEVER use non-return valves or pressure limiting valves in the branch • These create imbalance in the branches • Non-return and pressure reducing valves must be in a train on the cold water inlet COLD WATER SUPPLY TO WATER HEATER MANIFOLD

  32. BRANCHES • Last branch should be a T piece, not an elbow, to maintain equal resistance in all branches T PIECE

  33. Chapter 5 - Commercial CFWH

  34. USE MM AND FF ADAPTERS IF HORIZONTAL LENGTH OF HORIZONTAL TERMINATING FLUE EXCEEDS 2.7M TRIM RING USE CONDENSATE DRAIN & TRAP IF VERTICAL SECTION OF HORIZONTAL TERMINATING FLUE EXCEEDS 2M RHEEM INDOOR CFWH – FLUE SYSTEMS

  35. Rheem Multipak, Tankpak, Commpak and Commpak PlusCommercial Continuous Flow Hot Water Solutions

  36. Chapter 6 - Commercial Gas Storage

  37. RHEEM Commercial Gas Storage • Work horse of the industry • 3 input sizes – 50, 110, 200MJ/hr • Indoor and outdoor models • Multi-fin flue technology • Flue damper • Hot Surface Ignition • Up to 82oC • Room sealed flue

  38. HD Gas Layout

  39. 631275 Room Sealed Flue • Converts outdoor model to indoor room sealed • Ideal where no ventilation, contaminated air supply or fluing to roof impractical • 3m and 3 x 90o bends • Re-use flue terminal • Kit P/No 299135

  40. Chapter 7 – Raypak Heating and Hot Water

  41. Raypak Layouts

  42. Chapter 8 - Commercial Electric Storage
