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

Kastom Solar 200Ltrs Non Pressurized Solar Water Heater (Gravity Flow) is a medium‑capacity, gravity‑fed solar thermal system designed for 4–5 person households where mains water pressure is low, intermittent, or unavailable. It operates on the simple thermosiphon principle without any electricity – cold water from a roof‑mounted header tank flows into the solar collectors, heats up, rises naturally into the 200‑litre storage tank, and then flows by gravity to taps, showers, or appliances. No pump, no controller, no moving parts.

This model is ideal for off‑grid rural homes, small clinics, staff quarters, and any gravity‑fed water system. The 200L capacity comfortably serves a typical family of 4–5, providing hot water for bathing, washing, and kitchen use.

Key Features

• Gravity flow operation – No mains pressure required; works with a header tank elevated at least 1 metre above the heater.
• Non‑pressurized tank – Operates at near‑atmospheric pressure; simple, reliable, and safe.
• Collector type – Typically evacuated tubes (standard for Kastom gravity systems), providing excellent insulation and performance even in low sun or cool conditions.
• Tank construction – Inner tank: SUS304 stainless steel (food grade, 1.2mm thickness). Outer tank: UV‑stabilised steel with white or shiny metallic finish.
• Insulation – High‑density polyurethane foam (50–55mm thick, 32–40 kg/m³) – outstanding heat retention, keeping water hot overnight and into the next day (48–72 hours).
• Zero electricity – No pump, no controller, no backup element required (though an optional 2kW AC element can be added for cloudy periods).
• WARMA compliant – Approved for consumable borehole water in Kenya (Water Resources Authority).
• Durable mounting frame – Heavy‑duty galvanised steel (1.5mm thickness), suitable for flat or inclined roofs.
• Complete package – Includes tank, solar collectors, mounting frame, flex connectors, TP valve (temperature & pressure relief), and optional electric backup.

Technical Specifications

Best Used For

• Gravity‑fed systems – Homes, small schools, clinics, lodges without mains pressure.
• Off‑grid installations – No grid electricity required.
• Borehole water – Suitable with optional corrosion protection (SUS316 tank or sacrificial anode).
• 4–5 person households – Typical family or small group.
• Rural and peri‑urban areas – Where water pressure is low, unreliable, or non‑existent.

Advantages & Benefits

1. Zero electricity cost – No pump, controller, or moving parts; operates on solar thermal alone.
2. Strong corrosion resistance – SUS304 stainless steel tank resists rust, even with borehole water.
3. Superior heat retention – Polyurethane foam keeps water hot overnight and well into the next day.
4. Low maintenance – Only occasional cleaning of glass tubes and checking of connections.
5. Simple, reliable thermosiphon – No mechanical failures; lasts for decades.
6. WARMA approved – Legal and safe for borehole water consumption.
7. Compact 200L capacity – Ideal for medium‑sized families, fits smaller roofs.
8. 5‑year warranty – Backed by local East African support and spare parts.

Installation Requirements

• Header tank – A cold water storage tank (e.g., plastic or galvanised) must be installed at least 1 metre above the solar heater’s top connection. Typically placed on the roof or a raised platform.
• Roof structure – Must support the weight of 200L water (~200 kg) plus tank and collectors (~40–60 kg). Reinforce if necessary.
• Piping – Use standard UPVC or copper pipes sized for gravity flow (minimum ¾ inch). Insulate exposed pipes to prevent heat loss.
• Collector orientation – Facing north (in the southern hemisphere) or south (in the northern hemisphere) at an angle equal to local latitude (±10°).

Warranty & Support (Across East Africa)

• 5 years – On tank and solar collector (manufacturing defects).
• Genuine spare parts – Locally available (tubes, tanks, pipes, valves).
• Professional servicing and repair – Trained technicians.
• Expert installation support – Guidance and on‑site services.
• Countrywide delivery – Kenya, Uganda, Tanzania, Rwanda, Burundi, South Sudan.
