Kastom Solar 200Ltrs Non Pressurized Solar Water Heater | Gravity Flow

The Kastom Solar 200Ltrs Non-Pressurized Solar Water Heater is a gravity‑flow, open‑loop system designed for households or small commercial setups with low or no mains water pressure. It operates on the simple thermosiphon principle: cold water from a header tank (or borehole storage) flows into the solar collectors, heats up, rises naturally into the storage tank, and then flows out by gravity to taps or showers. No pumps, controllers, or electricity are required.

✅ Key features:

• Tank outer finish: Available in white or shiny metallic color.
• Inner tank material: Food‑grade SUS304 stainless steel (SUS316 optional for highly aggressive borehole water).
• Insulation: High‑density polyurethane foam (typically 50–55 mm) – excellent heat retention, keeps water hot overnight.
• Pressure rating: Non‑pressurized (gravity flow) – works with header tanks as low as 1 meter above the heater.
• WARMA compliant – approved for use with consumable borehole water in Kenya.
• Durability: UV‑stabilised outer shell, heavy‑duty mounting frame included.

✅ Best suited for:

• 4–5 person households.
• Off‑grid homes, rural clinics, small lodges, staff quarters.
• Areas with mains pressure below 0.5 bar or unreliable supply.
• Borehole water applications – optional sacrificial anode available.

✅ Advantages:

• Zero electricity consumption – no pump, no controller, no moving parts.
• Corrosion‑resistant – stainless steel tank will not rust.
• Polyurethane insulation outperforms traditional fiberglass, reducing overnight heat loss.
• Lightweight compared to pressurized tanks – easier rooftop installation.
• Low maintenance – simply keep the glass tubes (if evacuated tube type) clean.

✅ Warranty & Support (East Africa):

• 5 years on tank and collector (manufacturing defects).
• Local spare parts, professional servicing, and expert installation available.
• Countrywide delivery across Kenya, Uganda, Tanzania, Rwanda, Burundi, South Sudan via Kreatives.co.ke.
