Why Your Home Needs a Flat Plate Solar Water Heater
For households seeking reliable hot water, flat plate solar heaters are a durable, low-maintenance choice. The absorber panel heats water even in mild winters, while the glass cover prevents heat escape. Unlike complex systems, they require minimal upkeep—just occasional cleaning. Pair them with a backup electric heater for cloudy days. Perfect for families of 4-6, they provide 80-300 liters daily, depending on size and sunlight availability.
