What Is Electric Hot Water System?
An electric hot water system is a type of water heating system that uses electricity as its primary energy source to heat water for domestic, commercial, and industrial purposes. This system is widely used and popular due to its ease of installation, energy efficiency, and cost-effectiveness. Electric hot water systems come in various configurations, providing hot water on-demand or storing heated water for later use. Here's how an electric hot water system works and its key features:
Basic
Components:
An electric Hot Water Melbourne typically
consists of the following basic components:
a. Heating Element: The heating element is the
primary component responsible for heating the water. It is made of a
high-resistance material, usually a metal alloy that heats up when an electric
current passes through it.
b. Thermostat: The thermostat is a temperature
control device that monitors the water temperature and regulates the heating
element accordingly. It ensures that the water remains at the desired
temperature setting.
c. Tank (Storage Models): In storage tank
electric hot water systems, a tank is used to store the heated water until it
is needed. The tank is insulated to minimize heat loss and maintain the water
temperature.
d. Pressure Relief Valve: To prevent excess
pressure build-up in the tank, a pressure relief valve is installed. It
releases water if the pressure exceeds a safe limit.
e. Cold Water Inlet and Hot Water Outlet: The
cold water enters the system through the cold water inlet, and the hot water is
supplied through the hot water outlet.
Working
Principle:
The working principle of an electric hot water
system involves the following steps:
a. Cold Water Inlet: Cold water enters the
system through the cold water inlet and fills the tank in storage models or
directly enters the heating chamber in tankless models.
b. Heating Element Activation: When hot water is
required, the thermostat activates the heating element. The element heats up
and transfers the heat to the water.
c. Water Heating: In storage tank models, the
heating element heats the water in the tank to the desired temperature and
maintains it until needed. In tankless models, the heating element heats the
water as it passes through the system on demand.
d. Thermostat Control: The thermostat
continuously monitors the water temperature and turns off the heating element
when the desired temperature is reached. If the water cools down, the
thermostat activates the heating element again to maintain the set temperature.
e. Hot Water Supply: In storage tank models, the
heated water remains in the tank until it is needed. When a hot water tap is
opened, the hot water is drawn from the tank and supplied through the hot water
outlet. In tankless models, the heating element instantly heats the water as it
flows through the system, providing hot water on-demand.
