🔆 Description

The 300L Solar Water Heater Non-Pressurized Seven SS is a solar-powered water heating system designed for homes 🏡, businesses 🏢, and industries 🏭. It utilizes solar energy ☀️ to heat water, reducing electricity ⚡ or gas 🔥 consumption.

This system operates on the thermosiphon principle 🌊, meaning it relies on natural convection rather than pumps to circulate water.

It is non-pressurized, working at atmospheric pressure 🌬️, making it ideal for gravity-fed water supply systems. The Seven SS model features a stainless steel (SS) inner tank 🛢️, ensuring durability and resistance to corrosion.

🛠️ Maintenance

🔹 Regular Maintenance Tips:

1. Vacuum Tube Cleaning 🧽

   • Clean every 3–6 months to remove dust for optimal heat absorption.
   • Use a soft cloth and water to avoid scratches.

2. Tank Maintenance 🔍

   • Check for leaks or corrosion in the stainless steel tank.
   • Flush the tank once a year to remove sediment buildup.

3. Insulation Check ❄️

   • Ensure the insulation layer remains intact to prevent heat loss.
   • Replace if necessary.

4. Pipe & Connection Check 🚰

   • Inspect pipes and joints for leaks.
   • Use anti-scale treatment in areas with hard water.

5. Backup Heater Maintenance (If Installed) ⚡

   • Test and inspect periodically.
   • Avoid overuse—solar heating should be the primary method.

6. Cold Climate Protection ❄️

   • In freezing conditions, add antifreeze protection or insulate the pipes.
   • Drain the system if not in use during winter.
