OVERVIEW

This project aim was to provide Starehe Girls’ Centre with clean energy for water heating in the school kitchen used to clean utensils, cooking and keeping food warm ready for serving. . With an average hot water consumption of 1,800 litres per day, the cost of using electricity and other non – renewable sources of energy had been high. The solar water heating system installed in the institution utilizes green energy, cuts on energy costs, and last but not least saves mother nature.

Whilst most people probably think of solar power in terms of rooftop panels that generate electricity many people are not aware that domestic solar power can take another form – that of solar thermals. Solar thermals are used exclusively for heating water and represent not only an environmentally friendly solution to domestic energy needs but also can make you significant savings on your electricity costs
THE RENEWABLE ENERGY HUB

Based on the schools demand for hot water, the following split SWH system was installed by Sunraserg Energy Experts:

  • 9 (2m x 1m) flat plate collectors
  • 1800 litres fully insulated hot water reserevoir
  • Heat exhanger.
  • 100W silent pump.
  • Controller and temperature sensors for maximum efficiency.
  • Expansion tank to prevent loss of working fluid.
  • Safety valves for over pressure protection.
  • Magnesium anode to prevent corrossion.
  • Fully insulated cold and hot water plumbing.
  • Truss for collectors and tank support.
