COLD AND HOT WATER SUPPLY SYSTEM
Cold water supply system
Types of cold water supply system:
1.
Direct System
-Water is supplied direct from
mains to fixtures
Advantages:
:<3: Reduces pipe works and cost of same as pipes to and from tank for cold water are omitted
:<3:saving in pipe work
Disadvantages:
:no_entry:: If water is supplied only for specific period of time continuous water flow will not be available and such system cannot survive
:no_entry:no store of water
2.
Indirect System
-Water going to overhead
tank and also supplied to different floors
by gravity
Advantages:
:pencil2: Less maintenance – no additional burners to maintain
:pencil2:There is no risk of back siphon age
with this system
Disadvantages:
:red_cross:If water is supplied only for specific period of time continuous water flow will not be available and such system cannot survive
:red_cross:Longer pipe runs are required
Parts Of Water Distribution System
1.Service pipe
2.Distribution pipe
3.Riser
4.Fixture branch
5.Fixture supply
Hot water supply system
:check:Thermodynamic process.
:check:Using an energy source
Types of hot water supply system:
1.Solar energy
2.Heat pumps
Hot water heat recovering
4.Geothermal heating
Electrical heating system
-The cost of heating water by electricity is more
expensive
Types of electrical hot water system
1.Tank-less Water System
Advantages:
:red_flag:Unlimited hot water
:red_flag:Reduced risk of water damage
Disadvantages:
:black_flag:Start-up delay
:black_flag:No operation with low pressure
2.Storage systems
Advantages:
:unlock:High flow rates
:unlock:Low maintenance costs
Disadvantages:
:lock:Hot water require recovery time
:lock:Storage space needed
Solar water heating system
Advantages of Solar Water Heating
System
:
:star:Safety
:star:Savings
Disadvantages of Solar Water heating System:
:fire:Compared to photovoltaic panels, solar thermal panels only heat water.
:fire:The system does not function on cloudy, rainy, or foggy days.
