Solar Water Heater Systems

Hot water is a basic necessity, and traditional water heating methods often increase electricity costs. Solar water heaters use sunlight to provide hot water efficiently throughout the year.

Whether you run a home, office, hotel, hospital, or industrial facility, you need reliable hot water every day. Instead of depending on boilers, you can switch to solar solutions to reduce energy costs and improve efficiency.

Moreover, solar water heating systems use clean energy, helping both businesses and households lower their carbon footprint while saving money.

Flat Plate Collectors

This solar collector uses an aluminium body with a toughened glass cover. A copper absorber plate captures maximum heat from sunlight and transfers it directly to the water.

The insulated collector box prevents heat loss and improves overall performance.

Evacuated Tube Collector

This system uses glass tubes with a vacuum layer that provides excellent insulation. The outer tube absorbs sunlight and converts it into heat.

The system then transfers this heat to the water flowing inside the tubes, ensuring efficient heating even in low sunlight conditions.

How does the Water Stay Warm?

Thermosyphon

In this the water in the storage tank circulates continuously through the collectors, based totally on the natural flow of water due to difference in specific gravity of hot and cold water. It does not have to rely on electricity and is a simple and maintenance free system. However in this system, the temperature cannot be controlled and as hot water is drained from the tank, it is replaced by fresh cold water, leading to some amount of mixing

force flow

Forced Flow

The flow in this system is controlled through a control panel and pump. The cold water is circulated through the collectors and allowed to stay there until the set temperature is reached. Only then does the pump come on and push the heated water into the storage tank. The entire system is automated and hence it has to rely on electricity supply. In this system the temperature can be controlled, and water in the storage tank at any given time is at the set temperature only.

Hot water during non-sunny days too!

The insulated storage tank can be fitted with an optional heating element which will allow the system to function all-year-round.
