AQUA SOLAR WATER HEATER SUPPLIER MALAYSIA

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

Each AQUASOLAR 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 AQUASOLAR Solar Water Heater Malaysia 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.

AQUA SOLAR WATER HEATER SERVICE & MAINTENANCE

THE THERMOSIPHON PRINCIPLE

AQUASOLAR 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, AQUASOLAR products are cost-effective to own, use and maintain.

Getting A Solar Water Heater / FAQ

1. How many people will be utilizing the heating system?

Model/ units Usage Maximum of bathroom
L66 x 1 1 ~ 6 people 1 – 4 bathroom
L80 x 1 1 ~ 8 people 1 – 6 bathroom
L66 x 2 1 ~ 12 people 1 – 9 bathroom
L80 x 2 1 ~ 14 people 1 – 11 bathroom
*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 is the most ideal place to allocate the Solar?

  • 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. Does your property have a flat or sloped roof?

To facilitate the water flow through the system, the solar collectors need to be installed at an inclination, i.e. sloped roof. For flat roof installations, an angled rack needs to be used to provide the necessary inclination.

5. What are the things included in the basic installation?

  • 10 feet of SUS304 grade stainless steel water pipes for hot can cold water
  • 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?

  • Crane/Sky lift (usually needed for high buildings, eg: buildings higher than 25 feets)
  • Extra hot/cold water pipes which more than 10 feet
  • Internal house’s power point for the backup heater

7. When should I switch on the backup heater?

  • Raining season
  • Over usage of hot water
    • 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 60ºC. 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.
  • 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

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.

 

  • 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

 

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.

Instant Heater
Number of instant heaters : 4
Cost per instant heater : 350
Installation cost : 150
Cost of Purchase : 4 x (350 + 150) = RM2000
Number of persons : 6
Number of showers per day : 2 per person
Average time per shower (min) : 15
Heating element rating : 3.3kW
Electricity tariff : 0.276kW/Hr
Monthly Cost : 6 x 2 x (15/60) hour x 3.3 x 0.276 x 30 days = RM81.97
Yearly Cost : RM81.97 x 12 months = RM983.64
AQUASOLAR L66 Heater
Cost per solar water heater : 5250
Installation cost : 0
Cost of Purchase : RM 5250
Return On Investment (ROI) : 5250 – 2000 = 3.3 years
