A solar water heater works hard every day under the Malaysian sun. Like any system exposed to heat, rain, and dust, regular maintenance is key to keeping it efficient, safe, and long-lasting.

With proper servicing, you can:

• Prevent unexpected breakdowns

• Improve heating efficiency

• Extend the lifespan of your system

• Avoid costly repairs

Some basic checks can be done by homeowners, but for safety reasons, any work involving roofs, ladders, piping, wiring, or hot work should always be handled by a qualified technician. Always request a quotation before proceeding with servicing.

What’s Included in a Professional Solar Water Heater Servicing?

1. Cleaning of Solar Collectors

Solar collectors need direct sunlight to work efficiently. Over time, dust, bird droppings, leaves, and other debris can accumulate on the surface, reducing heat absorption and overall system performance.

Our team will:

• Wash the solar panels and remove dirt, debris and surface buildup

2. Inspection for Leaks & Damage

Even small leaks can lead to reduced efficiency, water damage, or costly repairs if left unattended.

We check:

• Pipes and connections

• Storage tank condition

• Signs of cracks, rust, or corrosion

3. Collector Glazing & Seals

The glazing and seals protect the collectors and help retain heat. Damage or wear can cause heat loss and reduce performance.

We inspect:

• Glass condition
• Seals around the collectors

4. Storage Tank & Sediment Build-Up

Mineral deposits and sediment can accumulate inside the storage tank over time, affecting heating efficiency and water flow.

Our servicing includes:

• Checking for leaks, rust, or corrosion

• Flushing the tank (if required) to improve efficiency

5. Valve & Heating Element Inspection

Valves and heating elements play a critical role in maintaining safe water pressure and consistent hot water supply. Faulty components can lead to leaks, poor heating performance, or even system failure if left unchecked.

We ensure:

• Valves (non-return valve) are clear and functioning correctly

• No pressure or blockage issues

6. Temperature & Pressure Safety Checks

Safety components protect your system and household from overheating or excessive pressure.

We verify:

• Thermostat settings

• Pressure relief valve is operating normally

7. Plumbing & Wiring Connections

Loose or damaged connections can cause leaks, electrical trips, or system malfunction.

Our team will:

• Check for fluid leaks at pipe joints

• Ensure wiring connections are tight

• Inspect insulation on pipes and wiring

8. Support Structure Inspection

A secure mounting structure is essential, especially for roof-mounted systems exposed to wind and weather.

We inspect:

• Nuts and bolts for tightness

• Signs of corrosion on metal parts

• Structural stability of the collectors

How Often Should You Service Your Solar Water Heater?

We recommend professional servicing every 2–3 years, or sooner if you notice:

• Reduced hot water temperature or no hot water even on sunny days

• Electrical tripping (short circuit) when switching on the backup heater

• Leaks or unusual noises

• Visible rust or damage

A trained technician can identify issues that may not be visible to homeowners.
