These direct & indirect circulation systems create a natural pressure. Sustainable system principle with less maintenance. You get sales due to cost-effective design & higher pressure than a conventional system.

High Heat Efficiency:

Harness maximum efficiency from the solar water heater system. Selective coating on the evacuated tube collectors keeps the water hot. Insulated integral collector storage systems reduce heat loss. 

Customers get warm water in cold climates, even at freezing temperatures. Enhance the customer’s experience and build long-term loyal customers. 

Durable and Long-lasting:

They have a less complex & more durable design. Simple integrated collector storage keeps the system functional for a long time. It needs less maintenance as it does not have circulating pumps. 

Save water heating costs more than conventional water heaters. Less maintenance results in a reliable and long-lasting passive solar water heater. Establish your brand image through the reliability of your solar heater.

Sustainable design:

Heat transfer liquid works great for both Glazed & unglazed flat plate collectors. Its anti-freezing solution maintains the temperature in the passive solar water heaters. Evacuated tube solar collectors transfer the solar energy to the tank. 

It has low operating costs as compared to active systems. You outsource at a low price and sell with good profit margins. Better ROI with less marketing costs for your enterprise.

Continues water supply:

In Passive heating systems, hot water circulates independently, saving energy. Reduces the energy or water heating bills in the HYBRID solar heater.   

CUSTOMERS get hot water by injecting the cold water into the bottom of the tank. Also, the pressurized tank keeps the supply. Enhance the end-user experience and receive positive feedback. Get more sales and business growth opportunities.

Successful Project

60kw Solar Heating System in Indonesia

It was a small Airport building in Indonesia. The owner wanted to install a renewable energy system. We install solar panels for clean electricity with a vast battery storage. The solar panels get integrated into the building’s facade easily. 

Then, we added a solar hot water system into the building. A passive solar water heating system provides enough hot water for many purposes. Sunlight was great throughout the year, so they functioned with maximum efficiency.

50KW off-grid panel system in Columbia 

50KW of energy is needed for a commercial building on the remote side of Columbia. It did not have any electricity supply coming from any side. So, the owner wanted to have a complete off-grid system. 

We designed a system including solar cladding & rooftop panels. A passive solar water heating system was installed for heated water. The solar water heater is working perfectly in all seasons.

    Can I have a sample?

    Yes, you have a sample from passive solar heating system suppliers. Check the built quality, frame durability, and heat efficiency. You also hire an inspection agent who gives you detailed inspection reports.

    How does a passive solar heating system work?

    PASSIVE solar water heaters have a solar collector that absorbs solar heat. The solar heat exchanger fluid transfers the heat to the storage tank through pipes. It works with Natural Convection and thermosyphon system Effect. 

    Can it be used in winter?

    Of course, you use them in winter to heat water. It works perfectly in low temperatures due to an anti-freezing coating. You may experience a performance dip on days without sunlight.

    How much does passive solar heating system cost?

    A passive solar heating system costs around 5000$ to 10000$. It depends on how much efficiency and capacity you want. It costs less if you only want hot water instead of a whole house heating system. 

    How to identify the quality?

    You must check the Solar collector, frame, storage tank, and overall built quality. Yet it is difficult to get a whole quality inspection. Hire a quality inspector like Leeline Energy for a complete quality inspection. 

    Focus on your business & let our team of experts handle the rest.
