V-Guard solar water heater maintenance service Coimbatore

A properly maintained V-Guard solar water heater lasts 15–20 years. Neglected systems fail in 5–7 years. This annual maintenance checklist from Arun Hitech — servicing 1,500+ systems in Coimbatore since 2010 — keeps your system running at peak performance.

Annual Maintenance Checklist

🔧
1. Clean Evacuated Tubes (Every 6 Months)

Dust and bird droppings on ETC tubes reduce efficiency by up to 25%. Wipe with a damp cloth early morning. Do NOT use hard brushes — tubes are fragile.

💧
2. Check for Scale Buildup (Annual)

Coimbatore's hard water causes limescale inside the tank. Annual descaling with diluted acid solution restores 15–20% lost efficiency. Best left to Arun Hitech technicians.

🔩
3. Inspect Pipe Insulation (Annual)

UV exposure degrades foam insulation on pipes, causing heat loss. Replace cracked/peeling insulation. Arun Hitech uses weather-resistant insulation tape rated for Coimbatore's climate.

⚡
4. Test Backup Heater Element (Annual)

The electric backup element should be tested before the monsoon season. A failed element leaves you without hot water on cloudy days.

📋
5. Check Warranty & AMC Coverage

V-Guard provides 5-year warranty on the tank and 2 years on collector. Arun Hitech's AMC (Annual Maintenance Contract) covers all the above at ₹1,500–₹2,500/year — far cheaper than a repair bill.

⚠️ Warning Signs That Need Immediate Service:
  • Water temperature suddenly dropping
  • Reddish/rusty water from hot water tap
  • Visible cracks in ETC tubes
  • Water leaking from tank or connections
  • Unusual noise when water heats up
