Worked Solution & Example Answer:A modern wood burning stove, as shown in the sketch, is fitted with a back boiler - Leaving Cert Construction Studies - Question 3 - 2014
Step 1
Draw a labeled diagram showing the pipework
Answer
- Start by sketching the water storage tank at the top of the diagram. Make sure to include an overflow pipe coming out of it.
- Draw the rising main, which connects from the water storage tank to the hot water cylinder.
- Illustrate the stove and back boiler next to each other, showing the connection between them and the hot water cylinder via the pipework.
- Ensure to include valves at appropriate junctions in the system for controlling the flow of water.
- Label each component of the diagram clearly to identify them.
- Finally, indicate the insulation around the water storage tank and pipework, illustrating where the insulation is applied.
Step 2
Discuss two advantages of adding a solar panel to supply hot water to a dwelling house.
Answer
-
Reduced Energy Costs: Solar panels reduce the cost of heating water as they harness energy from the sun, which is free. By using solar energy, homeowners can significantly lower their electricity bills associated with conventional water heating.
-
Environmental Benefits: Solar energy is a clean and renewable resource. By switching to solar panels for hot water supply, there is a substantial decrease in reliance on fossil fuels, thereby reducing carbon emissions. This contributes positively to combating climate change and promoting sustainable living.
