Flat Plate
Solar Water Heater
SolarMaster Flat Plate Solar Water Heaters
are suitable for both residential and commercial applications.
The design of the Flat Plate Solar Water Heater is a culmination of nearly 15 years of feedback from installers and solar professionals all
over the world and aims to meet their requirements with the following key features:
●Easy and Safety Packing design (Tank, frame and Flat plate collector in separate packages)
● Top Color Steel for Outer tank, Stainless Steel 304-2B for inner tank
● Galvanized Steel with oil printing mounting frames
● Extremely reliable Tank design, less brazing points
● High efficiency Germany Tinox energy AL solar absorber
● Ultra lightweight top quality rock wool insulation
● UV stabilized components
● High tensile grade 6063-T5 black anodized aluminum body
● High transparency solar glass
SHC collectors are available in 10 to 30 tube sizes and have a number of options depending on the local market requirements.

How It Works
The Flat Plate Solar Water Heater is comprised of three main parts:
Pressurized Flat Plate Solar Collector
Absorbs solar energy and converts it to usable heat. The header and riser pipes are brazed together to form a harp shaped heat exchanger that the solar system heat transfer fluid circulates through.
Water Tank
It stock the hot water from the Flat plate collector, and keep the heat.   
Mounting Frame
Strong and easy to install with various options to match different mounting methods.
Snow & Wind Loading
SolarMaster Solar Water Heaters are rated for up to 298kg/m2    /  62lbs/ft2 snow loading.  The roof and attachment points must also be suitably rated.
Mounting frames are available for the SolarMaster Solar Water Heater that can withstand category C cyclonic winds (250km/h / 159mph).  For such conditions there are specific requirements that must be observed.
