  1. VELUX Solar Water HeatingProduct Introduction

  2. WELCOME TO VELUX SOLAR WATER HEATING TRAINING

  3. OBJECTIVES OF THE TRAINING • Understand existing solar technologies and how VELUX solar water heating systems fit into the market • Learn how to install and service VELUX Solar Water Heaters • Gain knowledge of our product range and price structure • Learn how to specify the right Solar Water Heating system • VELUX Solar sales and marketing tools

  4. UNDERSTANDING SOLAR:Current sources of energy

  5. TWO MAIN TYPES OF SOLAR ENERGY1: PHOTOVOLTAIC (PV) Conversion of solar energy to electricity Low efficiency (10-22%) Cost of typical household system: $30-50000 • Suppliers: • BP • GE • Sharp • Sanyo • Various startups

  6. TWO MAIN TYPES OF SOLAR ENERGY2: SOLAR HOT WATER Using sunlight to heat water for showers, appliances and space heating High efficiency - Will cover 50-80% of hot water demand Cost of typical residential system: $5-8000 • Suppliers: • VELUX • Handful of small US players • European and Chinese entrants

  7. DEFINING VELUX SOLAR PRODUCTS Solar Energy Indirect (a result of the sun -- wind, wood, hydro) Passive(Skylights,windows, greenhouse) Direct(heating & power generation) PV (Solar energy converted to electricity) Active(Storage or conversion) Thermal(Collected for heating) Open System(direct) Thermo Siphon(Passive systems) Closed System (Indirect-HX) VELUX Solar = Solar Water Heating Drain back (Draining collectors) Direct, Active, Thermal, Closed system, Pump driven, Fully flooded, Flat plate collector, Solar water heating systems! Pump driven(Active systems) Evacuatedtubecollector Fully flooded Flat platecollector

  8. VELUX SOLAR WATER HEATING SYSTEMS

  9. VELUX SOLAR WATER HEATING SYSTEMS • Simple, low cost, “Plug-&-Flow” installation • Systems for 3-4 person homes • Systems for 5-6 person homes • All components meet VELUX Quality Standards • VELUX proven “leak proof” components • VELUX solar collectors • VELUX flextubes • U.S. certified tanks and components • UL approved storage tanks • UL approved pump and controller • U.S. certified solar systems • SRCC approved collectors and systems • U.S. building code compliant 1 2 3 4 5

  10. VELUX SOLAR HOT WATER SYSTEMS: CHANGING PERCEPTIONS

  11. VELUX IS COMPLETE SOLAR SYSTEM

  12. VELUX Solar Water HeatingSystem Components

  13. VELUX SOLAR COLLECTORS

  14. VELUX SOLAR COLLECTORS & FLASHINGS • CLI 4000 Collectors • CLI U12 4000 • CLI S06 4000 • CLI M08 4000

  15. VELUX COLLECTOR CONSTRUCTION Integrated connection points Slimline Cladding Silicone sealed glazing Laser welded absorber Integrated installation brackets Rock wool insulation Aluminum frame and back

  16. FLUID FLOW IN VELUX CLI 4000 COLLECTORS

  17. AIR FLOW IN CLI 4000 COLLECTORS

  18. COLLECTOR TEMPERATURE SENSOR

  19. FLEXTUBES AND CONNECTIONS • ZFR: Tube between solar collectors • ZFR EF0 – shingle roof installations • ZFR GH0 – tile roof installations • ZFR: 140-220-320 to be used if there is a VRW between 2 collectors. • Tube must be pre-bent. • ZFM: Flex tubes between solar collector and tank • ZFT 002: To connect 2 ZFR or ZFR and ZFM

  20. SOLAR STORAGE TANK TYPES/SIZES Indirect Solar w/Electric Auxiliary 80 and 120 gallon Indirect Solar w/Boiler Auxiliary 80 and 120 gallon

  21. BALANCE OF SYSTEM Thermostatic Mixing Valve Expansion Tank Pump Station Microbubble Air Separator Propylene Glycol

  22. SOLAR TANK INSTALLATION

  23. VELUX Solar Water Heating Principles of Operation

  24. PRINCIPLE OF SOLAR THERMAL COLLECTION

  25. TRANSMISSIVE SELECTIVITY (Greenhouse Effect)

  26. ZFM CONNECTION PLUG & FLOW DESIGN

  27. SPIROVENT MICROBUBBLE AIR SEPARATOR For theseparationandremovalof microbubblesof air from the system Unique valve is guaranteed not to leak Air chamber protects valve from dirt Solid construction for extended service life • No manual venting required • Leak proof operation assured • Extended component life • Nonoises from the “cascading effect of air” • Low pressure drop

  28. SYSTEM CONTROLLER OPERATION PRINCIPLE System Controller • Protects system from overheating • Extends heat transfer fluid life • Can be used to meter solar energy

  29. EXPANSION TANK OPERATION Heat Transfer Fluid Heat Transfer Fluid Heat Transfer Fluid Solar System Filled, with collectors covered Maximum Pressure at highest temperature of heat transfer fluid Out of the box • Protects system from pressure buildup • Collects heat tranfer fluid as it expands
