A solar water heater uses rooftop collectors to heat water directly from sunlight, cutting the electricity or gas that would otherwise go into your geyser or boiler. It's one of the fastest-paying-back solar investments available, especially in a climate as sunny as Coimbatore's.
As a TEDA & MNRE enlisted manufacturer and solar system integrator, Dev Solar supplies and installs solar water heating systems for individual homes as well as larger institutional needs — hostels, hotels, and hospitals with high daily hot-water demand.

Water heating is one of the largest hidden costs in a home or institution's power bill:
A well-sized system can meet the bulk of your hot water needs year-round, with your existing heater only kicking in as backup on the cloudiest days.
We assess your daily hot water usage — number of occupants, peak demand times, and existing plumbing — to recommend the right tank capacity and collector size. For institutions with high-volume needs, we design systems that scale accordingly.
Installation is straightforward on most rooftop types, and once commissioned, the system needs only periodic checks to keep performing at its best.
Our non-pressurised evacuated-tube range has an SS-coated PC-structure outer tank and a porcelain glass-lined inner tank, runs on both hard and soft water, and ships with a backup electric heater. An air-vent pipe is required on all non-pressurised models.
