We installed an Anu Solar Water Heater May 2013. We used to get water heated up to 42 degrees C. Under five years, it is getting erratic. Certain days it heats up water to 37 degrees C, other days water remains at 32 degrees C. The water tank is rusted.
The firm or their agent did not provide the invoice or completion certificate, despite requests.
Now when contacted, they want the invoice number. The product is substandard with poor after-sale service.
