1.0 Introduction
For customers to use energy efficiently be it for domestic or industrial utility when heating water in a system, there is a need to use a micro-controller based water heater. The domestic water heater which is also called a geyser accounts for 43% of the household's total power consumption which makes use of the fact that efficient control of temperature of geyser will reduce the overall domestic power consumption of the entire nation.
By definitions, a micro-controller based water heater or geyser is a type of water heaters which makes it possible for consumers in the domestic premises and industrial areas to efficiently control water heating system.
Without this, consumers may find it difficult to make a daily routine of switching their geysers OFF or ON manually and keep setting thermostat to meet their requirements, for different periods of the day in a week.
In this hardware and software designs are the controller which is interfaced with a real time digital watch, a temperature sensor and a keypad. In this, a real time emulator driven by the software controls a water heater using a micro-controller.
We have the micro-controller, the geyser, keypad, interface design and consumption. The mechanical device such as thermostat is not meant for frequent adjustments and does not offer that accuracy and precisions required by a consumer to control temperature. The technique used is very crude to determine hotness or coldness of water in a geyser.
These devices have high cost, required higher maintenance due to wear and tear; depending on specifications of materials the electronic controller is design to control water heating from a remote point using a personal computer and an intelligent temperature sensor. It is user friendly, efficient, and has longer lifespan and is supported by a simple software designed to control the water heater and controls temperature accurately and precisely, saves electrical energy if judiciously programmed and is a mechatronics device.
