*The calculation at the left is based on a shower head (6”) and 10 minutes for each person bathing.
*Calculation is for guidelines only, as many factors will affect the result. Eg: time of bathing, weather, water pressure, sizes of shower head.

As a guideline, households with up to 6 people should opt for the 66 gallon models, whereas larger households can either choose the 80 gallon models or to install two or more smaller systems.

Remember that Jacuzzis and bath tubs use a lot of water – factor in about 15 gallon (68l) per use for a regular bath tub.

2. Where to allocate the solar water heater?

  • Roof which can fit the Solar Water Heater.
    • L66 – 1800mm x 2400mm
    • L80 – 2400mm x 2400mm
  • Direction (accordingly)
    • South
    • North
    • East
    • West
  • Height (Recommended)
    • Highest of the building to avoid blocking
  • Roof trust
    • Ensure the trusses is strong enough to support the weight of solar (especially for L80)
    • Recommend to re-inforce the trusses for old buildings
  • Near cold water tank
    • Normally will recommend to install nearby the cold water tank and the pump’s location as cold water supply to the solar is from the cold water tank
3. What things to prepare before installation?
  • Hot and cold water piping system. 0.5 inches (½”) Stop-cock have to be standby in 10 feet below/nearby the Solar Water heater, is either inside or outside ceiling.
  • 15 Amp Power Point required to be ready in 10 feet below/nearby the solar water heater.
  • If the house is require a pump, will recommend to install it before install solar.
  • Water and electricity supply
4. What type of roof can install the solar water heater?

Aquasolar hot water system can be mounted at any position, however we will usually recommend that the Solar water heater should be installed at an inclination. We advise you to installation at highest location for optimum heat absorption.

For flat roof installation, an angled aluminium rack should be installed to provide necessary inclination.

5. What is the basic installation included?

  • Three (3) meter of hot and cold stainless steel piping for solar system inlet and outlet.
  • 3kW Backup electrical booster and thermostat
  • Italy pressure temperature valve (PT valve) to control the pressure

6. What are the things excluded in the basic installation?

7. When should I turn on the heating element?

  • Raining season
  • Over usage of hot water
  • Hazy season
8. Will I get hot water even on rainy days or nights?

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 fiberglass 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.
 

9. Do I need to install a water pressure Pump for the solar?
 

All AQUASOLAR™ products are high-pressure systems which means you only need one water pump to drive both cold and hot water throughout the house. AQUASOLAR is not need to have a pump for its 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.

10. How much do I save?

Appliances with heating elements consume the most electricity in our homes. Using solar water heaters will help you make significant savings when compared to the cost of purchasing, installing and using instant heaters and boilers.

Here is a typical comparison in between instant heater and solar water heater.

ENSURE THE QUALITY OF PRODUCTION

Each AQUASOLARTM product features high quality aluminium, copper and stainless steel construction that offers years of trouble-free ownership and usage.

Each AQUASOLARTM water heating system comes with two collector panels – each with 10 copper risers paired with 2.97m2 of collector fins with selective black coating for optimal heat conversion and performance-to-weight ratio.

Hot water is stored in a marine-grade 316L steel storage tank, which requires no sacrificial anodes to replace or rust and cracks to worry about. 316L steel tanks offer superior performance over industry standard 304 steel tanks.

All AQUASOLARTM products are designed to perform under high-pressure. High pressure solar heaters do not create a loss of pressure when water passes through it, which means homes using such systems only require one water pressure pump. On the other hand, low-pressure systems require one water pump for the cold water and another for the hot water.

THE THERMOSIPHON PRINCIPLE

 

AQUASOLARTM products rely on the thermosiphon principle to drive water through its system. Thermosiphon occurs when heated liquid rises and is replaced by cooler liquid in a closed circuit. As the cycle is repeated, the temperature of the liquid in the entire system is gradually raised.

Because there are no pumps or motors, AQUASOLARTM products are cost-effective to own, use and maintain.

Why Choose Aqua Solar?
 
·         AQUASOLAR is designed to meet local requirements
Being a locally made with high grade material, AQUASOLAR is adapted to meet the requirement of house owners in this region. While other solar water heaters boast of impressive thermal collectors which work even in winter, AQUASOLAR offers you only what you need. It is specially designed for the equatorial region where there is longest sunshine and most constant temperature. AQUASOLAR designed a range of 66 & 80 gallons models to suit the majority needs in local.
 
·         AQUASOLAR is proven safe
Customer safety is our top priority. That is why we have made AQUASOLAR safe for you. Water is heated to about 70°C and the safety feature of a pressure temperature relief valve controls the heat pressure. Our storage tanks are suitably designed and tested for bursting pressures. AQUASOLAR does not use an anode that causes high quantity of highly inflammable hydrogen gas to accumulate in the system, if the water from the heater is not used for two weeks or more.
 
·         AQUASOLAR is made of top quality material
AQUASOLAR is made of high quality corrosion-free material such as stainless steel, copper and aluminum to ensure long-life and performance. A proven outstanding material for the manufacture of domestic hot water tanks, stainless steel is highly resistant to rust and corrosion, even in relatively hard waters with a high chloride content. And it is capable of withstanding water temperatures up to boiling point. This excellent performance world-wide has made stainless steel the No. 1 choice for the manufacture of domestic hot water heaters and storage tanks in recent years. AQUASOLAR also uses 20 units of 6 feet long panel, the longest in the market, quickly transforming solar rays into thermal energy. A transparent low iron glass cover traps solar rays and reduces convective heat loss.
 
·         AQUASOLAR works simply and efficiently
AQUASOLAR uses a direct heating system which is the most suitable system in Malaysia in terms of cost and efficiency. Water circulates through 120ft with a natural process called thermosiphons to ensure better heating and no clogging, enhanced by the use of ten ½” copper tubes in each of its 2 panels. A more vertical tank offers better thermal stratification within the tank to ensure higher flow rates leading to higher efficiency.
 
·         AQUASOLAR retains heat efficiently to give you hot water in any weather condition
AQUASOLAR storage tanks are insulated with 50mm (2″) of high-density polyurethane and fiber glass wool to retain heats.
 
·         AQUASOLAR is maintenance-free
The concept of solar water heater is based on saving money and energy. Made of stainless steel, with no moving parts of any kind, AQUASOLAR fulfils this concept. Compare this with other brands which required expensive parts, replaced and heating fluid topped up. AQUASOLAR however, needs no maintenance at all. It is self-sustaining, guaranteed to run efficiently year after year at absolutely zero cost.
 
·         AQUASOLAR is guaranteed to last
A good solar water heater system should not only be reasonably priced but also durable to last 10 to 20 years to justify its initial cost. To prove our confidence in the performance and durability of AQUASOLAR, we are proud to attach a guarantee for the first (1st) year and 9 years warranty for the remaining years.
