The geyser consists of a water tank fitted with inlet and outlet pipes. Heating elements inside are controlled by thermostats to heat water to a set temperature without exceeding it. The tank is insulated and enclosed in metal casing. Geysers work by converting electrical energy to heat through resistance heating elements, raising the water temperature through conduction. Safety features prevent overheating and bacterial growth in the water.

3. • The geyser consists of a water tank fitted with two pipes – one for i
nlet of cold water and the other for outlet of hot water. The wate
r tank is fitted with heating elements which are controlled by therm
ostats. The thermostats ensure that water is not heated abo
ve a set temperature value. The tank is normally covered with som
e insulating material and enclosed inside a metal casing.
INTRODUCTION

4. • It was the invertion of an Englishman named
BENJAMIN WADDY MAUGHAN who named his
invention after the well known Icelandic not spring
called geyser.
• MAUGAN in turn influenced the work of Edwin rudd.
A Norwegian mechanical engineer. And it is he who
founded the modern day Electric water heater.
HISTORY

5. BASICINFORMATION
• Most electic water heaters use electric resistance element elements to heat the wa
ter in the storage tank using two electric resistance elements, which are located at
the bottom and top of the storage tank. Each element is controlled by an independen
t thermostat.
• Electric heating element is used to heat up the water stored in a storage tank.
• In two element tanks the lower element provides recovery from standby losses and t
he upper element provides heating during periods of large hot water use. Some resis
tance water heating.

7. Difference between water
HEATING ANDGEYSER
• In a way, it is not much different from a common immersion rod that we can dip i
nto the bucket, plug into the power socket and have the water heated up.
• The only difference is the level of sophistication and slight automation in the gey
ser.

8. TYPES OF GEYSERS
Types of geysers:
• ELECTRIC GEYSER:
Convert electrical energy to heat energy based on joules law of heating.
• FUEL COMBUSTION GEYSER:
Fuels like coal, LPG, wood are burnt and the heat energy generated in the com
bustion process is used to heat water.
• SOLAR GEYSER:
The light radiation from sun are directly captured, converted to heat energy
and used to heat water.
• GEOTHERMAL GEYSER:
Heat energy directly from inside the earth is used to heat water.

9. CONSTRUCTION OF ELECTRIC GEYSER
• The geyser conisits of a water tank fitted with two pipes – one for inlet of cold
water and the other for outlet of hot water.
• The water tank is fitted with heating elements which are controlled by thermost
ats.
• The thermostats ensure that water is not heated above a set temperature value.
• The tank is normally covered with some insulating material and enclosed inside a
metal casing.

10. PRINCIPLE
• The principle on which the geyser works is simply the conversion of electrical ene
rgy into heating elements of raise the temperature of water through conducti
on of the heat to the water.

12. Safety of geysers
• Explosion hazard:
When the water temperature exceeds 100 ˚C (212 ˚F),
the water will remain a liquid inside the tank, but when t
he pressure is released as the water comes out the tap the w
ater will boil, potentially inflicting stream burns. Water abo
ve about 88 ˚C (190 ˚F) will cause burns on contact.
• Thermal burns:
Human skins burns quickly at high temperature.
• Bacterial contamination:
Tank temperature above 60˚C may produce limescale de
posits , which could later harbor bacteria, in the water tank an
d can contaminate the water in it.

14. How does it works
• An electric water heater waorks essentially the same way as a gas water heater.
• It brings cold water in through the dip tube and heats it using the electric heating elemens inside of the tan
k.
• The hot water rises in the tank and is moved throughout the home through the heat-out pipe.
• A typical water heater will use around 4000 WAATS.
• The average use of hot water in a household is around 45 Gallons per day, to lower.
• Both the heating elements do not function simultaneously.
• First the top heating element functions until the upper tank is hot and then the function is transferred to t
he bottom heating element, which has its own thermostst.
• The thermostat is mainly a bi-metallic disk with each metal heaving a different co-efficient of expansion fo
r heat. So, when it gets heated up.
