A thermosiphon system relies on warm water rising, a phenomenon known as natural convection, to circulate water through the collectors and to the tank. In this type of installation, the tank must be above the collector. As water in the collector heats, it becomes lighter and rises naturally into the tank above. Meanwhile, cooler water in the tank flows down pipes to the bottom of the collector, causing circulation throughout the system. The storage tank is attached to the top of the collector so that thermosiphoning can occur. These systems are reliable.

• Is it 1.5mm 1.2mm 0.9mm or 0.5mm?

• We do out of 1.5mm Stainless steel

• There is no way for the customer to check this

• Any one can say “yes” 1.5mm but how can a customer check this 

• But the final result of non-standard wall thickness is the high risk of bursting the tank. 

• Warranty for upto 10 years only can help with this

• The Best question is “who will give a true 10 Year warranty”

• SUNBIRD HAS A 10 YEAR PROVEN WARRANTY

• Talk to our existing old clients. Out of our customer base of over 20,000 more than 5000 customers have already enjoyed the full 10 years of our warranty period and more.

• 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 the customer

• Because any one can say “yes” Black chrome plated copper but again how can a customer check this?

• Best question is “what is the average temperature increase per day with solar energy”

                      our flat plate type units reach 55-65C and vacuum tube type units reach 90-95C on average

  • Yes
  • This is a 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.

The Electrical Booster (Heating) Element is provided as a backup solution only for time when the usage of hotwater exceeds the capacity of the unit.

This heater element is not required to make hotwater in the SUNBIRD unit. However it is required if heavy usage or bad sunlight conditions occur.

Therefore it is recommended to select the correct capacity unit and avoid using the electricity.

All of our Pressure Bearable type units (Flat Plate Pressure, Flate Plate Ceramic, Vacuum Tube Pressure) are tested upto a pressure of 10 bars at our Quality Control phase. We recommend these units to be used with any plumbing system upto 6 bars of pressure

The ideal situation is to go for a unit that is on the higher side of your usage pattern.

This means that if you have usage of 3 or 4 persons per day, it is best to consider the higher number 4 and look at the product recommended for that range ("150l system"), rather than the lower range ("100l system"). This is because the energy from the Sun must be captured/stored which is a slow process, and it is vital that there is enough excess storage for gloomy days and maximum usage.

However, our Client Relations Officer will assist you in more detail considering roof direction, angle, shade, sun's path, pipe-lines, usage points etc.. He will make a FREE visit to your site to better recommend the best option.

The procedure to follow in selecting and purchasing a SUNBIRD unit begins with calling us using our hotline or directly calling or visiting our island wide network of showrooms. We will assign a Client Relations Officer who will give you a personalized service throughout the process, and assist you in any manner professionally. At any time you will have recourse to 2 contact points which are the Client Relations Officer and the Showroom Manager, who will have all your details and give the best recommendation in selecting and installing the unit.

Solar water heaters offer long-term benefits that go beyond simple economics. In addition to having free hot water after the system has paid for itself in reduced utility bills, you and your family will be cushioned from future fuel shortages and price increases. You will also be doing your part to reduce this country's dependence on foreign oil. Adding a solar water heater to an existing home raises the resale value of the home by the entire cost of the system.

Solar water heaters do not pollute. By investing in one, you will be avoiding carbon dioxide, nitrogen oxides, sulfur dioxide, and the other air pollution and wastes created when your utility generates power or you burn fuel to heat your household water. When a solar water heater replaces an electric water heater, the electricity displaced over 20 years represents more than 50 tons of avoided carbon dioxide emissions alone. Carbon dioxide traps heat in the upper atmosphere, thus contributing to the "greenhouse effect."

When investing in a solar energy system, it is cost effective to invest in making your home more energy efficient. Taking steps to use less hot water and to lower the temperature of the hot water you use reduces the strain on your solar water heater.

Good first steps are installing low-flow showerheads or flow restrictors in showerheads and faucets, and insulating any hot water pipes that pass through exposed areas. You'll also want to make sure your site has enough available sunshine to meet your needs efficiently and economically. This means trimming or removing/relocating of trees/objects in the vicinity of the solar unit.

There are many small home-based producers of solar hotwater systems these days. Take the same care in choosing a solar water heater that you would in the purchase of any major appliance.

Your best protection is to consider only certified and labeled systems, and the company background to look after your investment and their past record. Client testimonials are invaluable in this regard. Find out if the manufacturer offers a warranty, and, if so, what the warranty covers and for how long. If the dealer you are buying the equipment from goes out of business, can you get support and parts from the manufacturer?
