• Hot Water Distribution has Two Types

• Steam Water Distribution has Two Types

a System is commonly used in small residential houses and other industrial

installations with the following service features:

1. It provides constant circulation of hot water.

2. Hot water is quickly drawn from the fixtures at any time desired.

3. Provide economical circulating return of unused hot water.

4 Eliminate waste of water

• The Up-Feed and Gravity Return System

• The Overhead Feed and Gravity Return system

a System is an efficient type of hot water distribution generally used in

building of extreme heights

• The Overhead Feed and Gravity Return system

• The Up-Feed and Gravity Return System

1. The heating unit and the storage tank are placed below the distribution pipeline.

2. The heating unit should be near and accessible to serve the pipe system conveniently and efficiently.

3. The distribution main pipe is suspended from the ceiling of the basement. It is inclined upward from

the storage unit. The risers are connected to the distribution main.

4. The distribution main pipe is connected to the tapping on top of the storage tank closer to the flow

from the heater.
