Solar Water Heaters by Talwin
A solar water heater uses the sun to heat water. It gives hot water all day using clean, natural energy — and works beautifully in Bangalore, where there is plenty of sunlight for most of the year. You need far less gas or electricity to heat water.
Talwin is a trusted Solar Water Heater Distributor, Dealer & Supplier in Bangalore, offering reliable solutions from leading brands like Kamal Solar and Racold. We provide models for small homes, apartments, villas, PGs, hostels, hospitals and hotels.
What Is a Solar Water Heater & How Does It Work?
A solar water heater has special panels called solar collectors that sit on your roof.
- Collectors absorb heat from sunlight.
- Cold water flows through the collector and gets heated by natural circulation (thermosiphon).
- Hot water rises into an insulated storage tank.
- The tank keeps water hot for 24–48 hours — so you have hot water even at night and early morning.
- An optional electric backup heater with thermostat takes over on cloudy or rainy days.
We help you pick the right capacity and collector type based on your family size, water source (borewell, Cauvery or tanker) and roof space.

Frequently Asked Questions – Solar Water Heaters
Will a solar water heater work on cloudy days?
Yes. The insulated tank stores hot water for 24–48 hours, and the electric backup heater gives you hot water when the sun is weak.
Which capacity solar water heater do I need?
Plan for about 35–50 litres per person per day. A 100 LPD heater suits 2–3 people, 150 LPD for 3–4, 200 LPD for 4–5 and 300 LPD for 6–8 people. Use our sizing calculator below or ask our team.
Which is better for Bangalore — ETC or FPC?
If you use borewell or hard water, FPC is better because ETC tubes scale up quickly. For soft Cauvery water and budget installations, ETC works very well.
Can I install it on any roof?
Yes. We check your rooftop and install safely on flat RCC or sloped roofs, with proper structure and anchoring.
How long does a solar water heater last?
15–20 years with basic maintenance. FPC collectors typically last longer than glass tubes.
How much money will I save?
You can save 60–80% of your water heating bill. For a family of four using an electric geyser daily, that is often ₹800–₹1,500 a month.
Is it good for apartments?
Yes. We install individual systems for penthouses/villas and centralised systems with ring-main circulation for apartment blocks.
Is there a subsidy for solar water heaters?
There is currently no central capital subsidy for solar water heaters for homes, but BESCOM has historically offered a rebate on electricity bills for homes with solar water heaters. We'll guide you on current benefits.
