Sustainable 100L 500kpa High Pressure Close Coupled Solar Water Heating Kit

This roof mounted, close-coupled, solar hot water system can be easily installed on tile, steel clad or flat roofs. There are no complicated pumps or controllers to worry about as the circulation of the hot water is automatically achieved using the natural thermosiphon principle. The system is backed up by a thermostatically controlled electrical element.

  • 2 Year guarantee.
  • 500 KPA.
  • 10 Tubes per 100L.
  • Aluminium stand.
  • Green and White steel tank.
  • Includes the tank, stand and tubes.

Product Description

Details

Features and Benefits

  • Advanced evacuated tube & heat pipe technology.
  • Standard South African 32mm screw in heating elements with pockets are used.
  • Electronic control unit is optional, so you can control the energy usage.
  • High pressure system: up to 500kPa working pressure.
  • Easy installation.
  • Competitive prices. And the sun will give your money back!
  • The simple compact design leaves no space for extra components which can leak, freeze, burst, lose heat, or simply stop working.
  • The heat pipes fit directly into the tank. There is only a sleeve inside the tank, so heat loss is minimal.
  • Because the whole system is on the roof, it is easier to install, which also cuts costs. It obviously cannot leak through a ceiling.
  • This is a high-pressure system. It can be used for city pressure, although it has been tested at much higher pressures.
  • Problems with freezing can be expected only at -35°C.
  • Low pressure systems are substantially cheaper than high pressure systems.
  • All high-pressure systems use a 1.2mm stainless steel tank.
  • There is an optional electronic control panel, which controls the electric backup element. This panel controls 1, 1.5- or 2-kW elements, and can even be plugged into a normal three-point plug, as it draws less Watts than normal electric geysers.
  • A frequently asked question is about hail:
  • All our systems use 2mm tubes, designed to withstand 38mm diameter hail. They are surprisingly cheap to replace.
  • Replacement costs are in the price list.
  • Even if some vacuum pipes are broken, the system will still work.

Includes

  • 100L Green & White series,1.2mm s/steel tank (SUS 304).
  • Flat/pitched roof stand (1.5mm galvanized and painted).
  • 10 x 2mm heat pipe vacuum tubes (designed for 38mm diameter hail).
  • 500kPa temperature and pressure release valve.
  • 1 x Heating Element.
  • 1 x Standard Thermostat.
  • This geyser comes with a 2-year guarantee if installed correctly.

Tank

  • Outer tank material: Green & White series - 0.4mm White steel sheet.
  • Inner tank material: Both series' inner tank consists of 1.2mm SUS 304 stainless steel.
  • Insulation material: Both series have 55mm thick polyurethane foam between the inner and outer tank.
  • Weight: The high-pressure tanks can weigh up to 50kg.
  • Tank Capacity: 100L (10 tubes).
  • Working Pressure: 500kPa \ 5 Bar.
  • Maximum pressure: 900kPa \ 9 Bar.
  • Inlet/outlet pipes: 22 mm.
  • Electric backup element: 1kW standard SA 1½ inch boss element.
  • Mg anode: Protects against corrosion.
  • Certification: ISO, CE.

Evacuated Tubes

  • This is a standard 1800 mm length x 58 mm diameter x 2 mm thick glass tube. These tubes are designed to withstand 38 mm diameter hailstones.
  • Heat transfer into the high-pressure tanks is done with copper heat pipes. Heat pipes utilize a liquid which boils and condenses, thus causing an effective heat transfer cycle.
  • There is no water inside a high-pressure vacuum tube. Thin aluminium plates and a copper heat pipe transfer the heat from the hot black inner vacuum tube to the tank.
  • Material: Borosilicate Glass 3.3.
  • Vacuum: P<5x10-3Pa.
  • Thermal expansion: 3.3.
  • Absorptive coating: AlN/AIN - SS/Cu.
  • Absorptive coefficient: >92%.
  • Emission coefficient: <8%.
  • Stagnation Temperature: >250°C.
  • Net weight: ≥2.8kg.
  • Idle sunning property parameters: ≥ 175 m x °C/kW.
  • Solar irradiation for obtaining a pre-set water temperature: ≤4.7 MJ/ m2.
  • Average heat loss coefficient: ≤ 0.90 w/ (m2 x °C).

Support

  • Stand: 1,5mm galvanized steel.
  • Incline: 38° (flat installation), 12° (inclined installation, for 26° roof).
