Solar Water Heater
Your morning hot shower shouldn’t cost you a fortune every month. Yet for most households, the electric geyser quietly drains hundreds of rupees from the electricity bill — every single day. That is exactly why a 100 ltr solar water heater makes so much sense for Indian homes.
It is the most popular entry-level capacity, perfectly suited for a family of 2–4 people. Moreover, it uses free sunlight instead of electricity, which means real savings from day one. At Eco Solar Energy in Bangalore, we supply, install, and service 100 litre solar geysers for homes across the city. Therefore, in this guide, we cover everything — from price and types to maintenance and repair — so you can make the right choice.
What Is a 100 Ltr Solar Water Heater and Who Needs One?
This capacity is ideal for:
- A family of 2 to 4 members
- Daily use for bathing, cooking, and cleaning
- 1–2 BHK apartments and independent homes
- Small guesthouses or rental properties
ETC vs Flat Plate Collector Solar Water Heater: Which Should You Choose?
There are two main technologies available for a 100 ltr solar water heater. Understanding the difference helps you pick the right one for Bangalore’s climate.
ETC — Evacuated Tube Collector
ETC solar water heaters use vacuum-sealed glass tubes that absorb solar radiation with high efficiency. Because the tubes are insulated by vacuum, they perform well even on cloudy days and during cooler months
FPC — Flat Plate Collector Solar Water Heater
A flat plate collector solar water heater uses a black-painted metal absorber plate under a glass cover to capture sunlight. FPC systems are more durable, have a longer lifespan of up to 25 years, and look sleeker on rooftops.
100 Ltr Solar Water Heater Price in India 2026
One of the most common questions we get is: what is the 100 ltr solar water heater price in Bangalore? The honest answer is — it depends on the type, brand, and installation complexity. Here is a clear price breakdown for 2026:
Solar Water Heater Maintenance: How to Keep It Running Efficiently
- Clean the tubes or collector every 3–6 months — dust and bird droppings reduce efficiency. A simple wipe with a damp cloth does the job.
- Check for leaks in pipes and fittings annually — minor leaks left unattended can cause pressure loss and tank damage.
- Inspect the insulation layer — damaged PUF insulation reduces heat retention; replace promptly.
- Flush the tank once a year — this prevents scale buildup, especially in hard water areas of Bangalore.
- Check the backup heater element — if your system has electric backup, test it before the monsoon season.

Even the best systems occasionally need attention. If you are searching for solar water heater service near me or solar heater repair near me in Bangalore — you are in the right place.
