Answer: Solar water heater sizing formula for Coimbatore: 25-30L per person per day. Multiply by 1.25 for buffer. Example: Family of 4 = 4 × 30L × 1.25 = 150L minimum → choose 200L for comfort. Single person = 100L. Joint family of 8+ = 300L. Call Arun Hitech 99424 87774 for free size recommendation.
