Geyser Controller

I am trying to design a controller for a domestic geyser as a project and would have to use a microcontroller to do this. part of the requirements of the controller is for the user to be able to key in operation times for the geyser and required temperature, and the controller should also give feedback when the required temperature has been reached. If anyone can give me some useful information or any help on this topic, please email me at [email protected]

thanks.
