Solar Water Heater System
Commercial & Residential Solar Water Heater Systems
Cut your water heating electricity bills by up to 90%. Northsun solar water heating systems deliver 24×7 hot water using advanced 3-target Evacuated Tube Collectors (ETC) and heavy-duty Stainless Steel inner tanks.
3-Target Vacuum
SS-304 Inner Tank
50mm PUF Insulation
Solar Water Heater Capacity & Price Estimator
Select your required daily hot water capacity (LPD – Liters Per Day) to estimate family sizing, vacuum tube configuration, and estimated annual savings.
Engineered for Harsh Winters & Hard Water
Northsun solar water heaters are built with premium materials to ensure high hot water output even during freezing North Indian winters.
3-Target Vacuum Tubes
High-grade borosilicate glass tubes with 3-layer copper-SS-aluminum coating absorb over 95% of sunlight, providing fast water heating even on overcast winter days.
SS-304 Food-Grade Tank
Inner tank fabricated using high-grade SS-304 stainless steel with automatic TIG welding. Completely hygienic for bathing and domestic washing, resisting scale formation.
High Density PUF Insulation
50mm thick high-density Polyurethane Foam (PUF) insulation surrounding the inner tank ensures minimal heat radiation loss, keeping water hot for up to 72 hours.
ETC vs FPC Solar Water Heater Comparison
Understand the difference between Evacuated Tube Collectors (ETC) and Flat Plate Collectors (FPC) to choose what fits your setup.
| Feature / Specification | Evacuated Tube Collector (ETC) | Flat Plate Collector (FPC) |
|---|---|---|
| Primary Technology | Double-walled Glass Vacuum Tubes | Copper / Aluminum Absorber Plates with Glass Cover |
| Winter & Cold Weather Performance | Exceptional (Vacuum minimizes heat loss) | Moderate (Loses heat in high wind/cold) |
| Hard Water Resistance | High (Easy tube scale cleaning) | Requires Heat Exchanger or soft water |
| System Pressure Handling | Non-Pressurized (Gravity Flow) | High Pressurized Systems Supported |
| Affordability & ROI | Highly Economical (Payback in 1.5 – 2 Years) | Higher Initial Investment |
| Best Suited For | Homes, PGs, Small Hotels, Hostels | Industrial Plants, High-Pressure Pressurized Showers |
