Non-Pressurized Solar Water Heater | Affordable Hot Water System – Suntech Power. Solar Water Heating for Homes, Farms & Institutions
The Non-Pressurized Solar Water Heater from Techwin Limited, Kenya, is a reliable and budget-friendly choice for areas with good solar exposure and a gravity-fed plumbing system, ideal for domestic households, rural homes, farms, and institutions where high water pressure is not a requirement.
Non-Pressurized Solar Water Heater
A non-pressurized solar water heater is a solar hot water system that operates using natural thermosiphon flow and a gravity-fed water supply. It does not require high-pressure plumbing or pumps, making it suitable for areas with low water pressure or off-grid settings.
Water is heated using evacuated glass tubes that absorb solar energy, storing hot water in an insulated tank mounted on the rooftop.
