Solar Water Heater for Hard Water & Borewell Water
Quick Answer: For hard or borewell water, use an ETC solar water heater with a glass-lined tank and descale every 1-2 years to prevent scaling and maintain efficiency.
Many parts of Coimbatore, Tiruppur and Erode have hard water or borewell water with high mineral content. This can cause scaling inside solar water heater tubes, reducing efficiency over time. Here's how to handle it.
Why Hard Water Is a Problem
Hard water contains calcium and magnesium that deposit as scale inside tubes and tanks. Over time, scale blocks heat transfer, so the heater takes longer to warm water and efficiency drops.
Best Solution: ETC with Anti-Scaling Design
ETC (evacuated tube) models handle hard water better than FPC. Glass-lined tanks resist corrosion. Some models include anti-scaling features that reduce deposit build-up.
Regular Descaling Keeps It Efficient
In hard water areas, periodic descaling (every 1-2 years) removes mineral build-up and restores full heating efficiency. An annual maintenance contract (AMC) makes this hassle-free.
Optional: Water Softener
For very hard borewell water, adding a pre-filter or softener extends the life of your solar water heater and all your appliances.
