Solar Powered Water Heating System

Buy solar water heater with high hard water tolerance limit. CFC free solar water heating system with pure copper coating for high heat transfer.

Sunnet solar water heating system is a cost effecting option for your various requirements. Unlike the traditional systems, this is a high end energy saving option. With a capacity of 500 LPD and above, you can customize the design and specification of solar water heater that suites your specific requirement.

Solar water heaters use the Sun’s energy to heat water during the day. This water is stored inside an insulated tank for use whenever required. The Sun rays have enough energy to heat water up to 55°C to 70°C which is more than sufficient for bathing, washing clothes, use in kitchen, etc. With negligible maintenance requirement, Solar water heaters provide a low cost long term solution to getting hot water. For cloudy days, Solar water heaters have a built-in backup electric heating element. Solar water heating (SWH) is the conversion of sunlight into renewable energy for water heating using a solar thermal collector. Solar water heating systems comprise various technologies including FPC and ETC.

Solar-Water-Heater Solar Water Heater

There are two types of solar water heaters available, first one is flat plate collector and the second one is evacuate tube collector.

The flat plate collector (FPC) based system is of metallic box flat plat collector type, longer life compare to evacuate tube collector (ETC) system. FPC systems are available in with & without heat exchanger and It can also work with or without the pressure pump (pressurized and non-pressurized).

ETC Solar Water Heater (Evacuated Tube Collector)

Evacuated tube Collector (ETC) acts as an absorber in the solar water heater. Each evacuated tube consists of two glass tubes having vacuum in between which is an excellent insulator. The incident solar radiation falling on the tube passes through the outer transparent tube and strikes the outer of inner tube. It absorbs heat energy and then passes to the cold water flowing in the tube. An evacuated tube technology based solar water heating system is most energy efficient and cost effective. Suitable for Domestic Use.

MNRE approved solar water heater with subsidy benefit.  PUF insulation water tank for hot water storage upto 48 hours. Stainless Steel inner tank for longer system life. Triple layer coated vacuum tubes for higher efficiency. MS angle main parts with epoxy and PU coating.

FPC HE 500 ltr Solar Water Heater
In FCP heat exchanger 500 liter solar water heater, the air is evacuated from the solar tube to create a vacuum. FPC-based systems perform well with anti-freeze solutions at subzero temperatures but increase their cost. In other areas, both perform equally well. This greatly reduces conductive and convective heat losses from the interior of the tube. The resulting air and cold temperatures have less effect on the efficiency of the empty tube collector.
