Why Solar Water Heater?

  • Cost-saving
    Installing a solar water heater system is a sound investment. Since it is virtually maintenance-free and doesnot cost a cent to run, you pay once for the simply luxury of using hot water. Compare this with your electricity or gas bills month after month. While they keep accumulating over the years, a solar water heater sustains itself on the infinite rays of the sun. Electrical appliances are generally guaranteed for only 36 months, but with a solar water heater, you and your family will be assured of cost-free hot water for years to come.

  • Safety
    A solar water heater is extremely user-friendly. Just turn on the tap for hot water. Even a small child can do it. Water is heated to about 70oC and the safety feature of a relief valve controls the heat pressure. With the conventional electric heaters, there is always the fear of an electric or gas leakage. A solar water heater, however, has no electrical wiring of any kind and works safely on the sun’s heat. Potential gas leaking, dangerous explosions and electrical mishaps will be a thing of the past.

  • Convenience
    A solar water heater combines instant hot water with the therapeutic pressure of jet showers, an advantage unmatched by gas or electric water heaters. You are assured of instant hot water at a constant temperature and pressure, any time of the day and night. Whether for bathing, washing clothes and greasy dishes, you can use as much hot water as you like without worrying about the electricity bills. It can also be used as preheated water for cooking and boiling. A solar water heater has the advantage of providing several water outlets with hot water at the same time. And with a solar water heater, there is no power failure to contend with. When your neighbout is bathing in the cold and dark, you can enjoy a warm therapeutic bath, what can be more convenient?

  • Modern Living
    More and more people are adopting environmentally friendly lifestyles. Solar water heaters complement this modern lifestyle by providing the simple luxury of hot water without exhausting the earth’s resources or releasing carbon into the air through consumption of electricity. The solar water heater is the responsible choice for the modern consumer – an investment for future generations.

How does it work?

The L series uses Thermosiphon system in heating. The absorber collector is placed below the storage tank, from which cold water flows into the collectro where it is heated to a desired temperature. When sun is on the Solar Panel, the water in the panel is heated, becomes less dense and rises up into the Storage Tank. This continuous natural circulation of the water through the collector and tank heats the tank water over time, as flow stops as soon as the collector cold below the tank temperature.

How much do you save when you use renewable energy?

ELECTRIC WATER HEATER RM
Individual bathroom, bathroom only
6 persons • 15 minutes shower • 2 showers a day (180 minutes = 3 hours a day) • 3.8kW/hour x 3 hours = 11.4kW • 11.4kW x 30 days x 12 months = 4,104 kWh
3 electric water heaters (inclusive of installation, wiring & ELCB) x RM500 1,500.00
Total for 10 years (RM0.516 x 4,104 kWh x 10 years) + RM1,500 = (Based on Average electricity rate tariff RM0.516 and assuing there's no increase in the electricity rate tariff) 22,676.64

The tank itself is made of high quality stainless steel while the external casing is lined with aluminium to resist corrosion even after decades of use. That is why we have backed our product with 1 year guarantee and warranty for the remaining 9 years.

Why not start? Bathing in warm water is certainly more pleasurable not to mention therapeutic than bathing in cold water. It opens up the pores and allows trapped dirt to be released. There are also more functions of a water heater than just for bathing. For instance, washing of dishes and clothes with warm water not only cleans better, it is also gentler on hands.

The unit itself is mounted solidly on the roof where it receives maximum radiation from the sun. It is attached directly to a solid beam to allow it to stay firm even under the strongest of monsoon winds.

A short period of rainfall will not affect the supply of hot water because AQUASOLAR’s tanks are insulated with 50mm of high-density polyurethane and fibreglass wool to retain heats. On an average, it heats water to about 70oC in the day and loses only about 8% of heat at night. Even if it is overcast, there is enough radiated heat to maintain the temperatures of the water at a comfortable level. However, if there are few days of cloudy day, it would require to switch on the backup heater.

The backup heater generally will only kick in if turned on when temperatures are maintained below 60ºC, the heater will auto cut-off if the temperature reach above 60°C. AQUASOLAR systems have no problems maintaining this temperature throughout the night due to its excellent 50mm High density Polyurethane foam insulation. Hence, you will only need to switch on the heater in case of bad weather or excessive hot water usage (visitors, etc). Or just keep it on and let the thermostat control it for you trouble-free.

In a normal household of 4-6 people which spends approximately 20-40% of their electricity bills on water heating, the return on is usually within 3-5 years.

AQUASOLAR does not need to have a pump for it’s circulation through the system. Our solar system uses Thermosiphon system in heating, when the water is heated it rises. However, we are always recommend customer to purchase a pump for the cold water tank to increase the pressure of cold water for a better enjoyment.

The best Aquasolar model for your needs will depends on the following key factors :-
