200L Solar Water Heater: Low Pressure with Stainless Steel Tank

A 200L low-pressure solar water heater with a stainless steel tank is an affordable, eco-friendly hot water solution ideal for Kenyan households (2-4 people). It uses gravity-fed (thermosyphon) technology, where solar-heated water naturally circulates to the tank—no pumps needed. The stainless steel tank ensures durability and corrosion resistance, perfect for hard or borehole water. Based on current market data (October 2025), these systems cost KSh 35,000–KSh 55,000 installed, with a 3–5 year payback via energy savings.

Key Features

  • Capacity & Usage: 200 liters of hot water (up to 60–80°C) daily, sufficient for showers, laundry, and kitchen needs.
  • Low-Pressure Design: Non-pressurized (open-loop) system; water enters via gravity, reducing complexity and cost. Not suitable for high-pressure showers without a booster pump.
  • Stainless Steel Tank: Food-grade SS inner tank (e.g., SUS304 grade) with polyurethane foam insulation for 24–48 hours heat retention. Outer jacket: Powder-coated steel.
  • Collector Type: Typically 20–30 evacuated glass vacuum tubes (heat pipe or U-pipe) for efficient heat absorption, even on cloudy days.
  • Efficiency: 50–70% solar energy conversion; works in Kenya's climate with 6–8 hours of sunlight.
  • Warranty: 2–5 years on tank/tubes; 1 year on accessories.
  • Installation: Roof-mounted; requires south-facing tilt (10–30°). 
AspectProsCons
CostAffordable upfront; low running costs (no electricity).Initial install ~KSh 40,000–60,000 total.
PerformanceReliable in sunny areas; simple maintenance.Less efficient in cold/rainy seasons; needs backup (e.g., electric heater).
DurabilitySS tank resists rust; tubes last 10+ years.Vacuum tubes fragile (avoid hail); low pressure limits direct high-flow use.
Eco-FriendlinessZero emissions; reduces grid reliance by 70%.Requires roof space (~2m x 2m).
