1. Water Supply System And Other Plumbing Fittings
Part 2

2. Main Stages in Water Supply
In this lecture:
Hot Water Supply: Direct, Indirect, Mains Fed Indirect
Sanitary Fittings (both soil & waste and water supply): Cisterns, Sinks and Basins, Bath and Showers, Water Closets and Cisterns, Bidets, Wash Troughs, Urinals

3. Hot Water Installation
Direct System (pg 771)
Simplest & least expensive
Operation:
Water is heated in the boiler
Hot Water rises by convection to the hot water storage tank/cylinder
Hot water from the boiler mixes directly with the water in the cylinder.
Cooler water from the bottom of the storage vessel replaces hot water in the boiler.

4. Hot Water Installation
2. Indirect System (772 & 776)
More complex than direct system
Operation: Central heating unit is to be part of the hot water installation.
Pipe layouts similar to direct system
Indirect system: a separate small capacity feed cistern is required to charge and top up the primary circuit.
Hot water storage tank = a heat exchanger.

6. Activity
Sketch the diagram for both direct and indirect hot water supply reticulation system in the page 771 & 772. Use red for hot water flow and blue for cold water flow.
