Worked Solution & Example Answer:A wood-burning stove with a back boiler, as shown, is used to heat water for a dwelling house - Leaving Cert Construction Studies - Question 3 - 2018
Step 1
Show the pipework required to supply hot water to a shower
Answer
To illustrate the pipework for supplying hot water to a shower from a wood-burning stove, the following components must be included in your diagram:
- Wood-Burning Stove: This is the source where the water gets heated.
- Rising Main: A 15 mm rising main pipe should connect from the cold water storage tank.
- Insulated Cold Water Storage Tank: This should be noted with an overflow of at least 22 mm minimum.
- Ball Valve: A ball valve should connect the cold water storage tank to the hot water cylinder.
- Hot Water Cylinder: There should be a 28 mm primary flow from the wood-burning stove to the hot water cylinder.
- Expansion Tank: An insulated expansion tank should be included with a 22 mm overflow pipe.
- Pipework to Shower: The connection from the hot water cylinder to the shower should be shown with 22 mm hot water supply pipes.
- Necessary Valves: Include stop valves as needed for maintenance and control.
Step 2
Discuss one advantage of using a wood-burning stove to heat water for the house
Answer
One significant advantage of using a wood-burning stove to heat water for the house is its cost-effectiveness and environmental benefits. Wood is generally renewable and less expensive than gas or electric heating options. Moreover, modern wood-burning stoves are designed to achieve high efficiency and are capable of heating domestic hot water effectively.
Unlike fossil fuels, wood can often be sourced locally, reducing transportation costs and environmental impact. Utilizing waste wood or recycled wood can also help decrease energy consumption and carbon footprint. Additionally, using a wood-burning stove can supplement other forms of central heating or provide independent heating, ensuring a reliable hot water supply during colder months.
