The diagram illustrates the process by which hot water is made available and distributed in a house.

Overall, the provision of heated water in a house involves a series of process which includes sourcing of cold water from an underground source, a furnace and pipes through which it is distributed.

Cold water is directed through a pipe underground into the house which passes through a furnace. The furnace is heated by wood pellets which are added from time to time to heat up the water passing through the pipe. The residue from the pellets is collected into an ash receptable and the exhaust is passed along a smoke stack into the atmosphere.

As the water in the pipe is heated, it runs along a distribution channel to the living room and bedrooms on the second floor of the building.

Task Response

The report provides a general overview of the heating system, but it lacks specific details and comparisons that would enhance the summary. To improve, focus on identifying and reporting the main components and their functions more explicitly. Also, try to make direct comparisons between the pellet stove and pellet boiler systems if the diagram provides enough information to differentiate them. The report falls short of the required 150 words.

Coherence & Cohesion

The report presents a generally clear overview of the heating system. The description follows a logical sequence, making it easy to understand the process. However, the introduction could be more concise, and transitions between sentences could be smoother to enhance the flow of information. Consider using cohesive devices more effectively to link ideas and improve the overall coherence.

The vocabulary used is adequate for describing the diagram, but there's room for improvement in terms of variety and precision. While the terms used are appropriate, incorporating more specific vocabulary related to heating systems and building infrastructure could elevate the description. For example, instead of 'distribution channel,' more technical terms could be used. Also, avoid repeating the same words.

Grammatical Range & Accuracy

The report demonstrates a reasonable command of grammar, but there are noticeable errors that affect clarity. Pay closer attention to subject-verb agreement, correct tense usage, and article usage. Review the report carefully to identify and correct these errors. Varying sentence structure could also enhance the grammatical range and make the writing more engaging.
