A geyser sometimes becomes very essential in winter
season mainly for bathing purpose. How it would be if you can make an instant
geyser by your own hand?
In this post I am going to discuss how to make an
instant geyser and the cost of the material needed.
An instant geyser is slightly different from
conventional geyser . A conventional geyser gives hot water taking more time
than an instant geyser. Though it’s name is instant geyser, it takes near about
30 seconds to supply hot water. This type of geyser is not designed for large
capacities like a storage of hot water. An optimum volume of the container is
needed for proper heating.
Main working principle of instant geyser-
We all know that if current passes through a
resistance, the resistance becomes hot. This resistance heating principle is
implemented in instant geyser. The water first enters through the inlet and then goes to the container. But it
does not stay in the container, it almost immediately starts flowing through
the outlet. The geyser resistive element is placed inside the container. It consumes high
power(near about 3kw) to heat the water. The heating of the water depends on
the rate of flow of water. For high rate of flow heating will be low and vice-versa.
Here we use a thermostat switch for safety of the heating element. When the
flow of water becomes very low and the temperature inside becomes very high,
the thermostat switch automatically trips
OFF the power supply. The
temperature in which the thermostat switch will trip is prefixed and it depends
on it’s setting.
Here you can add an indicating lamp connecting to the mains.
What you must keep in your mind-
1.
Do not switch on the geyser without
assuring circulation of water through the geyser. Otherwise the heating element
will burn out soon.
2.
Dip the heating element fully in the
water.
3.
Must check the thermostat tripping
temperature before setting. This is in general 55 to 60 degree C.
4.
Must provide proper earthing.
