Worked Solution & Example Answer:A wood burning stove, as shown in the accompanying sketch, has a back boiler fitted - Leaving Cert Construction Studies - Question 3 - 2010
Step 1
Using a single-line labelled diagram, show the pipework required to connect the back boiler, cylinder and expansion tank.
Answer
To create a single-line labelled diagram that showcases the required pipework for connecting the back boiler, cylinder, and expansion tank, follow these steps:
-
Back Boiler and Indirect Cylinder: Start by drawing the back boiler connected to the indirect hot water cylinder. Label both components clearly.
-
Expansion Tank and Overflow: Include the expansion tank positioned at the highest point. Indicate the overflow pipe leading from the expansion tank.
-
Rising Main: Draw a rising main pipe originating from the back boiler to the indirect cylinder, ensuring the connection is clear and labelled.
-
Pipework and Insulation: Outline the pipework connecting all systems while adding indications for insulation on all hot pipes to prevent heat loss.
-
Valves: Incorporate control valves in strategic locations in the diagram, labeled for clarity. Valves typically include a control valve on the supply line and a drain valve near the bottom of the cylinder.
Make sure that all components are visually distinct and appropriately labelled for easy identification.
Step 2
Discuss two advantages of using a wood burning stove to heat domestic hot water.
Answer
-
Renewability and Cost-effectiveness: One advantage of using a wood burning stove is that wood is renewable and often less expensive compared to fossil fuels. This makes it an environmentally sustainable and economically efficient option for heating domestic hot water.
-
Environmental Benefits: Wood burning stoves utilize a local resource, reducing the dependency on fossil fuels. They also have the potential for lower carbon emission levels since trees absorb CO2 during their growth, contributing to a more sustainable cycle of energy use. As the world moves towards reducing carbon footprints, wood burning represents a viable alternative.
