Why Choose an SS Tank for Hard or Borewell Water?
Hard and borewell water carries salts and minerals. In ordinary tanks these cause rust, scale and blocked pipes, and the heater loses efficiency over time. A stainless steel tank resists this, so you spend less on repairs and replacements. The non-welded inner tank also removes the weld joints where leaks usually begin.
If your water is soft and your budget is tight, our GI/MS tank water heater is a good lower-cost alternative.
How an SS Tank Water Heater Works
Evacuated tubes absorb sunlight and heat the water. Hot water rises on its own to the tank (the thermosyphon principle), so no pump or electricity is needed for circulation. The PUF-insulated tank then keeps the water hot into the next day. These tubes are the heart of the system, and we make them ourselves as one of the ETC tube manufacturers in India.
SS Tank vs GI/MS Tank Water Heater
| Point | SS tank | GI/MS tank |
|---|---|---|
| Tank material | Stainless steel (SS 304L) | Galvanised iron or mild steel |
| Hard and borewell water | Well suited | Depends on water quality |
| Rust resistance | Higher | Good with GI coating |
| Cost | Usually higher | Usually lower |

Planning to Go Solar Beyond Hot Water?
Many customers start with a solar water heater and then cut their electricity bill further. Here is how our other solar services fit in.
Solar for Your Home
A rooftop solar system on the same terrace can power your lights, fans and appliances. As a solar panel company in India, we also supply the panels, and our team handles solar panel installation services from survey to commissioning.
Solar for Hotels, Offices and Factories
If your hot-water bill is only part of a bigger power cost, look at a commercial solar system with proper commercial solar installation. Factories with heavy daytime loads can explore our industrial solar solutions. For a complete design, supply, installation and maintenance contract under one roof, talk to a solar EPC company in India like us.
Solar for Farms and Irrigation
On a farmhouse or farm, the same sun that heats your water can run irrigation. See our solar pump range.

Frequently Asked Questions
What is an SS tank solar water heater?
It is a solar water heater that heats water with evacuated tubes and stores it in an insulated stainless steel (SS) tank. Ashirwad Solar makes SS tank systems in Pune in capacities from 100 to 1000 litres per day (LPD).
Can I use an SS tank water heater with hard water or borewell water?
Yes. The SS tank is rust-proof and is designed for hard water, salty water and borewell water, so scale and pipe blockage are much less of a worry than with ordinary tanks.
How hot does the water get?
The system is rated for hot water at about 60 degrees Celsius, and in strong sunshine it can reach higher temperatures. It also performs well on winter and cloudy days because of the evacuated tubes.
How long does the water stay hot?
The compressed PUF insulation keeps heat in the tank. The overnight temperature drop is about 5 degrees Celsius, and the tank is designed to retain hot water for more than 48 hours.
What is the difference between an SS tank and a GI/MS tank water heater?
Both use the same evacuated tube technology. The SS tank is made of stainless steel, so it resists rust and works well with hard and borewell water. The GI/MS tank is made of galvanised iron or mild steel and usually costs less. Choose by your water quality and budget.
What capacities are available?
We offer 100, 150, 200, 300, 500 and 1000 LPD systems. A 100 LPD system suits 1 to 3 people, 200 LPD suits 5 to 7 people, 500 LPD suits 18 to 20 people and 1000 LPD suits 35 or more people.
How much space does the installation need?
A 100 LPD system needs about 1.1 m x 1.9 m, a 200 LPD system about 2.0 m x 1.9 m, and a 500 LPD system about 3.7 m x 1.8 m of shadow-free roof or terrace area.
How much can I save with a solar water heater?
Our specification table lists expected annual savings from about 11,000 rupees for a 100 LPD system to about 50,000 rupees for a 500 LPD system. Your real saving depends on what you pay for electricity or gas today and how much hot water you use.
Does the inner tank leak?
Ashirwad's inner tank is made with non-welded technology, which avoids the weld joints where leaks usually start.
