avoid



Outdated Models

Avoid old stock that lacks modern safety and energy-efficient technology. Older geysers consume more electricity and lack features like auto cut-off or PUF insulation.



Oversized Heaters in Small Bathrooms

They waste energy and clutter your bathroom layout. Choosing the wrong capacity geyser increases power bills and takes up unnecessary space.



Fixed-Temperature Units

Limited flexibility and often waste more power. Fixed models lack control, making them less efficient and uncomfortable for daily use.



Uncoated Steel Tanks

Quickly rust and corrode, raising maintenance costs. Standard steel tanks fail in hard water, making them unsuitable for many Indian households.



No Local Service Access

Buying from brands without service support makes repairs costly. Lack of service networks in Tamil Nadu or Chennai leads to higher repair expenses.

How to Pick the Best Water Heater for Home

The right choice depends on your needs. If you live alone or in a compact home, an instant water heater is efficient and space-saving. For larger families, a storage water heater ensures consistent hot water supply for bathrooms.
