Calculations of circulation pump water flow, head, power and energy consumption for 150 liters domestic solar water heater.

Heating water with the sun is a practice almost as old as humankind itself. Solar Water Heating , now completely revised and expanded, is the definitive guide to this clean and cost-effective technology. Beginning with a review of the history of solar water and space heating systems from prehistory to the present, Solar Water Heating presents an introduction to modern solar energy systems, energy conservation and energy economics. Drawing on the authors' experiences as designers and installers of these systems, the book goes on to cover: Types of solar collectors, solar water and space heating systems and solar pool heating systems, including their advantages and disadvantages System components, their installation, operation, and maintenance System sizing and siting Choosing the appropriate system. This book focuses on the financial aspects of solar water or space heating systems, clearly showing that such systems generate significant savings in the long run. With many diagrams and illustrations to complement the clearly-written text, this book is designed for a wide readership ranging from the curious homeowner to the serious student or professional.

This work introduces a methodology for energy balance of solar water heaters (SWH). It describes the Israeli system for determination of the size of SWH, and calculations of the amount of energy gained by the SWH every month. It analyzes the central forced circulation system for the upper 9 floors of a residential building in Tel Aviv. The balance is for the demand scenario as determined using national statistics (unique to Israel). Electrical backup is 12% of the energy supplied by solar collectors. The balance shows that the energy consumption of hot water actually used is 57% of the total energy, and energy losses are 30%. 13% of the energy is not used as in summer SWH supplies more hot water than required. This work may be useful for a techno-economic evaluation of water heating options and calculations of optimal solutions. It also contains a large volume of useful data and information and can serve as a solar water heating manual or basic material for solar energy study.
