Kastom Solar 250Ltrs Non Pressurized Solar Water Heater | Gravity Flow

The Kastom Solar 250Ltrs Non-Pressurized Solar Water Heater is a large‑capacity gravity‑flow system designed for larger households or small commercial establishments (e.g., small lodges, staff quarters, community facilities) where mains water pressure is low or unavailable. Operating on the thermosiphon principle with zero electricity, it is one of the most reliable and maintenance‑free solar water heating solutions.

How it works:
Cold water from a roof header tank or borehole storage tank flows into the solar collectors (typically evacuated tubes or flat plates). The sun heats the water, which naturally rises into the 250‑liter storage tank. Hot water is then delivered to taps or showers by gravity alone – no pump, no controller, no pressure booster required.

Key features:

• Tank outer finish: Choice of white or shiny metallic color to match building aesthetics.
• Inner tank material: Food‑grade SUS304 stainless steel (corrosion‑resistant, hygienic). SUS316 available for highly aggressive borehole water.
• Insulation: High‑density polyurethane foam (50–55 mm thick) – superior heat retention, keeping water hot through the night and into the next morning.
• Pressure rating: Non‑pressurized (gravity flow). Requires only a small elevation difference (minimum 1 metre from header tank).
• Compliance: WARMA approved for consumable borehole water in Kenya.
• Durability: UV‑stabilised outer shell, heavy‑duty galvanised steel mounting frame included.

Best suited for:

• 6–7 people (recommended user count).
• Gravity‑fed systems in rural or peri‑urban areas with unreliable or low mains pressure (<0.5 bar).
• Off‑grid homes, small schools, churches, lodges, and staff quarters.
• Borehole water applications – optional sacrificial anode or special coating available.

Advantages & Benefits:

• Zero operating cost – no electricity for pumping or control.
• Corrosion‑resistant – SUS304 stainless steel tank lasts for years in harsh water conditions.
• Polyurethane insulation – reduces heat loss by ~30% compared to traditional insulation.
• Lightweight design – easier roof handling than pressurized tanks of same capacity.
• Low maintenance – just periodic cleaning of glass tubes (if evacuated tube type) and checking of connections.
• 5‑year warranty on tank and collector – peace of mind.

Warranty & Support (East Africa):

• 5 years warranty on tank and solar collector.
• Genuine spare parts available locally.
• Professional servicing and repair.
• Expert installation support for solar water heaters.
• Countrywide delivery and after‑sales care (Kenya, Uganda, Tanzania, Rwanda, Burundi, South Sudan).
