Ielts academic and General Task : How to write at a band level

This diagram outlines the manner in which water can be heated for domestic use via 
the sun.
Great! Now that we’ve given the big picture, we can start by describing the step-­‐
by-­‐step process involved in heating water with solar power. As we said above, the
water tank appears to be at the heart of this process, so let’s start our description
with the cold water that initially gets pumped into the house:
The household’s water tank is fed cold water (presumed to be coming from the city) 
at its base and dispenses hot water from its top.

Looking at the diagram, we can see that the water is not only heated by the sun, but

The tank water is heated in two ways. The first is via a traditional boiler heater, 
which likely circulates a heated anti-freeze solution through a pipe that coils within 
the upper part of the tank. The second connects another coil of pipe in the bottom 
of the tank to a pump and circulates the same anti-freeze solution to the roof of 
the house. From here, the solution is heated in a solar collector by the sun before 
circulating back to the tank.
Great. Now we should make note of the controller, which is connected directly to the
pump and likely controls the speed of anti-­‐freeze movement:
Water temperature is set using a controller, which dictates the rate at which anti-
freeze solution is pumped to the roof for heating.
Great work! Now, let’s read our composition in its entirety. As you read, you should
be making mental note of the phrases of cohesion we’ve employed in our writing:
