Answer (May 2026): For most Coimbatore homes, solar water heater is better if you have roof space and 4-6 hours of sunlight. Heat pump is better for apartments, hotels, or if you need 24/7 hot water. Solar saves ₹1,000/month, heat pump saves ₹900/month. Solar payback: 3 years. Heat pump payback: 16-18 months.
Answer: Solar water heater 200L costs ₹39,500. Heat pump 200L costs ₹1,45,000. Solar is ₹1,05,500 cheaper upfront. However, heat pump works without sunlight — ideal for Coimbatore's 4-month monsoon season (June-September).
Answer: Heat pump is recommended for apartments in Coimbatore. Solar water heaters need dedicated roof space (6-8 sq ft per person). Most apartments don't allocate individual roof space. Heat pump can be installed on balcony or utility area and serves the entire floor.
