🌞 150L Solar Water Heater - Non-Pressurized Seven SS
🔹 Description
The 150L Solar Water Heater Non-Pressurized Seven SS is a solar thermal system designed to heat water efficiently using solar energy. It operates in a non-pressurized configuration, meaning it relies on gravity flow rather than external pressure to circulate water. The system features seven stainless steel (SS) tubes for optimal heat absorption and transfer. It is an eco-friendly and cost-effective solution for domestic and small commercial applications.

🔧 Maintenance & Care
To ensure the long-term performance of the system, follow these maintenance guidelines:
1️⃣ Regular Cleaning 🧼
✔️ Clean the vacuum tubes every 2-3 months to remove dust and dirt for maximum heat absorption.
✔️ Wipe down the storage tank and frame to prevent rust or corrosion.
2️⃣ Check for Leaks 🚰
✔️ Inspect the system for leaks in the tank or pipe connections every 6 months.
✔️ Replace any damaged rubber seals to prevent water leakage.
3️⃣ Descaling & Water Quality 💦
✔️ In areas with hard water, mineral deposits can form inside the tubes and tank.
✔️ Perform descaling using a mild acid solution or vinegar every 6-12 months to maintain efficiency.
4️⃣ Inspect & Replace Insulation 🛡️
✔️ Check the insulation around pipes and the tank to ensure it remains intact.
✔️ If any insulation is damaged, replace it to prevent heat loss.
5️⃣ Backup Heater Check (If Installed) ⚡
✔️ If the system has an electric backup heater, test it periodically to ensure it functions properly.
6️⃣ Secure Mounting & Frame Stability 🔩
✔️ Ensure that the frame and stand are securely mounted to withstand strong winds or storms.
✔️ Tighten any loose screws or bolts every 12 months.
