Solar Space Heating System
Solar Space Heating System Dealer/ Supplier in Dehradun
Solar Space heating and cooling can be carried out by circulating hot or cold water through PEX pipes embedded in the floor of the space to be heated. The flooring could be of any type, even wooden. The source used for heating and cooling of water could be solar, a heat pump, or underground water. In each case, the system has to be carefully designed depending on the source of heat and the temperature conditions required. A solar space heating system uses solar thermal collectors to capture the sun's heat and distribute it indoors via air or water-based systems. It’s mainly used to reduce or eliminate the need for conventional heating
Etc Tube
The three super-high-efficiency selective coatings on the inner cover of high-boron- and silicon-content evacuated tubes absorb the heat. When the temperature rises, the density of water drops and the weight goes down; hot water will go up to exchange with cold water in the tank. In this way, the temperature of the water in tank goes up. ETC technology is suitable for domestic non-pressurised hot water applications.
A solar water heating system (also called a solar thermal system) uses sunlight to heat water for residential, commercial, or industrial use. It reduces the need for electricity or gas to heat water, leading to energy savings and lower carbon emissions.
Types of Solar Water Heating Systems
Solar water heating systems are mainly divided into active and passive systems based on how water or heat-transfer fluid is circulated.
Active Systems (With Pumps)
Use electric pumps to circulate fluid through collectors. More efficient and suitable for colder climates or larger systems.
Direct (Open-Loop)
Water flows directly through the collector. Best for mild, non-freezing climates.
Indirect (Closed-Loop)
Heat transfer fluid (like antifreeze) circulates through a closed loop. Ideal for cold or freezing areas.
Passive Systems (No Pumps)
Use natural convection to circulate water.
Fewer parts = lower cost and maintenance.
Integral Collector Storage (ICS)
Collector and storage combined. Good for warm climates.
Thermosyphon
Tank is mounted above the collector, using gravity flow. Reliable and simple, but may need roof reinforcement

Everything You Need to Know About Solar Water Heating Systems
Find answers to common questions about solar water heating systems, their working, benefits, capacity and maintenance.
A solar water heating system uses sunlight to heat water. It consists of solar collectors (panels), an insulated storage tank and a circulation system that transfers heat from the sun to water.
Solar collectors absorb sunlight → Heat is transferred to water or a heat-transfer fluid → Hot water is stored in an insulated tank → The hot water is ready for household or commercial use.
- Saves up to 60–80% of electricity bills for water heating
- Eco-friendly and helps reduce carbon emissions
- Low maintenance requirements
- Long-lasting and durable system
- Suitable for homes, hotels, hospitals and industries
The amount of hot water depends on the capacity of the solar water heating system. A 100-liter per day (LPD) system can meet the daily hot water requirements of a family of approximately 3–4 people.
Larger-capacity systems are also available for commercial and industrial applications where higher hot water requirements are needed.
Yes. A solar water heater can still operate during cloudy or rainy weather, although its efficiency may be reduced because of lower sunlight availability.
Most systems can be equipped with an electric or gas backup heater to provide a continuous hot water supply during periods of low sunlight.
A well-maintained solar water heating system can last approximately 15–20 years. Solar collectors are designed for long-term use, while storage tanks may require periodic inspection of their insulation and protective components.
