A Genuine Product

Our company cannot afford to produce, and then maintain – with a “genuine warranty” – a sub-standard product.

Isn’t it our obligation to our Clients that ensure we keep at the leading edge of technology and constant development? Therefore obviously we must have our own research and development team.

Someone who simply copies our product will only have a snapshot at that given time and not a genuine quality product we produce today. Someone who does that wont be able to develop it like we can and do. Lack of a secure future for both buyer and seller is evident when hot products are sold for a song.

Either we are lying about our product quality, warranty and genuine service, or those others are selling lower than low quality products at those unbelievable prices!

Which risk are you willing to take?

 

General Misconceptions and Our Responses

 

Take a look at this sample of typical points used in advertising campaigns by most suppliers…

Anyone can tell clients these “misleading information” to “WIN” a sale because it is usual marketing tactic to tell “white-Lies” which cannot be proven by the customer himself.

But as any professional and reputed company (which all our staff knows the actual product and the benefits and performance), we really don’t need to follow these methods of mis-information.

The intelligent and thoughtful end-user would understand our following explanations how these points should be truly considered …

 

1. What is the wall thickness of the internal tank? (ඇතුලත ටැංකියේ ගනකම කොපමණද?)

  • Is it 1.5mm 1.2mm 0.9mm or 0.5mm?
  • We do out of 1.5mm Stainless steel (අප එය 1.5  mm ගනකමින් නිපදවමු)
  • No way the check this by customer (මෙය පාරිබෝගිකයන්ට මතුපිටින් පරික්ෂා කොට දැනගත නොහැක).
  • Any one can say “yes” 1.5mm but how can a customer check this (ඕනෑම කෙනෙකුට ඔව් යයි පැවසිය හැක. 1.5mm ගනකම ඇති බව හෝ නැති බව කාටවත් තර්ක කල නොහැක).
  • But the final result of non-standard wall thickness will burst the tank (නමුත් අවසාන ප්‍රතිපලය වනුයේ අවශ්‍ය ප්‍රමිතියට තහඩුවේ ගනකම නැත්නම් යුනිට් එක සවි කොට ටික දිනකින් ටැංකිය පුපුරා යාමය).
  • Warranty 10 years only can help for this (වසර 10 ක වගකීම් මෙහිදී බල පැවෙත්වේ).
  • Best question is “who will give true 10 Year warranty” (වඩාත් වැදගත් ප්‍රශ්නය වනුයේ වසර 10ක වගකීම නිසි ආකාරයෙන් දියහැක්කේ කුමන ආයතනයටද යන්නය).
  • SUNBIRD HAS 10 YEAR PROVEN WARRANTY
  • Talk to our existing old clients.

 

2. What is the material of the fins and the tubes inside the panel?

  • Is it aluminum Copper or black chrome plated copper
  • We have black chrome or black chrome plated copper fins
  • No way to check this by customer (මෙයද පාරිබෝගිකයන්ට මතුපිටින් පරික්ෂා කොට දැනගත නොහැක).
  • Because any one can say “yes” Black chrome plated copper but again how can a customer check this? (ඕනෑම කෙනෙකුට ඔව් කියා කිව හැක).
  • Best question is “what is the average temperature increase per day with solar energy”             

i.e.: do we consider the newest plastic/aluminum parts of a brand new car engine? But we do consider if it is good mileage and pick-up and efficient – much better than old cars whose metal parts were made of Hard Steel.

 

3. Can a pressure pump be coupled to the system?

  • We have no problem regarding this

 

4. We now can provide anodic protection to your system?

  • This is standard in every sunbird at “No additional cost”
  • ALL OUR DEVELOPMENTS ARE INTEGRATED FEATURE OF OUR STANDARD MODEL, never do we offer for additional cost.

 

FURTHER Points to Note:

  1. Our products are backed by more than 25 years of dedication and development and experience.
    • Many new suppliers have no experience in the field and are looking to make a fast-buck. They give at low–cost because they have no plans to honor their warranty to the client.
    • After 2-3 years the customer is left without a service from these suppliers who have made their money and now closed!!
    • Reputed and long-term companies such as JFA-SUNBIRD just can’t do that.

 

  1. Because of this we need constant development to keep our product as the best possible (without constant repairs – which is a loss to us).
    • So we must always find the long-term solutions to reduce repairs and develop the unit to the maximum.
    • This benefit is entirely given to the customer at no additional cost.

 

  1. Carefully consider your investment in “Lowest Priced” products in the market as these are indicative of “Short-Term’ planning by suppliers who usually have NO PROGRAM of DEVELOPMENT and SERVICES.

 

Technology and Guidelines

Pressure-bearable type

These systems should be used for all water-lines with over 0.6kPa pressure, with general maximum operating pressure of approx 7bars (0.0kPa).

Non-Pressure-bearable type

These systems are suitable for installation where the plumbing lines do not have more than 1 bar of pressure (lower than 0.6kPa).

 

Flat-plate technology is the manufacture of the heat collector panel with copper tubing (risers) with aluminium fins for the quickest heating capacity.

 Flat-Plate Systems (FTP)

Vacuum Tube Pressure (VTP) and Vacuum Tube Non-Pressure (VTN) Systems use the Evacuated Tube Technology, and are highly efficient systems for solar water heating. 

FTP and VTP systems can be installed as split type units where the tank and panels are in separate locations much like split-type airconditioners. Although a simple separation of less than 10m with a gradient of panel-tank of > 8° is usually possible, we also have electronically controlled pumped systems. However the further the separation, there is greater heat loss and degrading of the systems efficiency which needs to be taken into consideration when deciding placement of tank and collector.

Split Type Model (STP)Split Type Model (STP)

The Electrical Booster Backup Element is an additional feature that compliments the use of our system for use whenever there is insufficient solar heating - i.e on rainy days and/or when higher than normal usage occurs (for example when you have visitors). However you must take care in selecting the correct sized unit according to the standard sizing chart, as you can avoid heavy expenses on electricity due to constant boosting due to usage more than the recommended capacity of the system.

Our aim is not to provide an electrically operated hot-water system, but to give the user a fall-back device for use in poor-weather conditions and occasional high usage scenario. On its own the solar hotwater system should be of sufficient capacity to provide the average daily consumption of hot-water. Frequent usage of this accessory could mean that the system is of insufficient capacity for your usage.

These panels are used for split type VTS units.

Manifold Panels

Central Solar Hotwater Systems are custom built to each Client's (Project) requirements and have to be carefully considered due to the installation requirements of main Hotwater tanks, panel arrays and electronic control and pumping systems. Also thought needs to be put into maintenance personnel and delivery circulation systems, system and backup down-time strategy and accessibility for installation and removals/replacements.

Central Systems (CEN) 

Our Standard Tube Size: 58×1800mm Tubes: In the market, there are different kinds of vacuum tubes for solar water heater. One is common tubes, another is triple layer technology vacuum tubes, and this one we call it “Violet Gold” vacuum tubes for its appearance of a violet gold colour. “Violet Gold” High efficiency heat focus vacuum tube is made by the newest nanotechnology, its absorb floor is made from copper, stainless steel and aluminum by the 12 -floor spatter plating technology. High boron silicon glass is chosen. By the sis-c/cu selective complex coat, the vacuum tube has the high absorptions and low reflectance. The Violet gold vacuum tube has the heat preservation effect because of its vacuum interlayer and its temperature can be up to 360 degrees, whereas the other vacuum tubes only could reach 200 degrees.

Problems and Solutions

Common issues and REAL SOLUTIONS for consideration.

 

A “Non-Pressure Bearable” type unit is installed usually due to the overhead tank (water supply) being at a low height. This means if there is any air blockage in the water lines to/from the SUNBIRD unit, it will not be cleared out due to the weak pressure (“push” factor). Air blockage usually occurs due to the overhead water tank getting empty, and therefore it should always be kept full – so it is best to have an automatic “floater” switch to keep the water from dropping to empty. If you have an air block you need to “bleed” the air from the line, and also recommend you to have your plumber fix the automatic floater switch to the overhead tank in order to avoid this problem for the future.

Some user experience this issue, which has a straightforward resolution: In our experience, almost all of these cases are caused by higher usage than the recommended use of that particular model. I.e: the family has expanded and or new equipment uses extra hotwater than initially expected. Basically the usage pattern has changed and therefore the capacity of the system also should. Other reasons to be considered are, higher usage (by additional personnel) - i.e use by unauthorised persons such as in the kitchens and or staff quarters... Trees and over-hangs / next door buildings that gives shade thereby the unit cannot get enough sunlight for good efficiency. Also higher flow-rates of water due to pressure pumps or flow-pumps being installed Additional usage points being added, longer pipes, extra wastage and leaks.
