14. Design of plumbing systems for multi-storey buildings

14.3 Hot water and other dual supply systems Dual drinking-water supply systems are those in which two different grades of water are available in separate piping systems. An example is the provision of a tap at a sink supplying water directly from the incoming water service while all other fixtures are fed from a storage tank.Cited by: 80Publish Year: 1994Author: J.

The more a pump must run, the more wear and tear occurs to the pumping mechanism and the electric motor. An under-sized pressure tank can cause a water pump to run an excessively.

An explanation of danish double tank solar water engineering system volumeJul 18, 2015One of the main functions of a pump is to move an amount of water from point A to point B, usually via pipes. While the pressure that a pump produces is very important, the volume of water that is moves while producing that pressure is even more so as the volume of water is the thing that irrigates a crop, fills a tank or puts out a fire.

Passive solar design takes advantage of a buildings site, climate, and materials to minimize energy use. A well-designed passive solar home first reduces heating and cooling loads through energy-efficiency strategies and then meets those reduced loads in whole or part with solar energy.
