General Information on needs of hot water
Example:
An installation of agro tourism is maintained by a family of 4 persons that live in the
residence. During the period between May and August the average occupancy is 15
clients per day. For the occupants 2 meals are prepared per day and the dishwasher
washes 5 times per day.
Needs of family:
4 x 60 lt = 240 litres / day
Needs of the clients: 15 x 50 lt = 750 litres / day
Kitchen:
30 x 10 lt = 300 litres / day
Dishwasher:
5 x 20 lt = 100 litres / day
Total:
1.390 litres / day
In the next table we present the daily consumption for other applications:
Hospitals and clinics:
80 litres / bed
University residences:
80 litres / bed
Dressing rooms, public showers:
20 litres / person
Schools:
5 litres / student
Restaurants:
8 to 15 litres / meal
Bars:
2 litres / client
Prisons:
30 litres / person
Factories:
20 litres / persona
Offices:
5 litres / employee
Gymnasiums:
30 litres / user
The information of the above table can also be used in combinations so that in every case
the average daily consumption can be properly calculated.
In the case that a recirculation system exists for the hot water usage, you will also have
to take this into account for the needs. The calculation will have to be made every time
individually from the above tables and depends on the dimensions of the circuit and
it’s
thermal insulation. Additionally, in the determination of the total needs, the thermal losses
of the total distribution circuit from the point of storage to the points of final consumption
must be taken into consideration.
In every case, the real needs for hot water are related to the personal attitude, the possible
special characteristics and habits of every place and application and also the way each
application functions.
For this reason, a specific calculation can be made by using the information on the gas/
petrol or electric bill. A flow meter installed on the hot water pipes could also be used.
