Worked Solution & Example Answer:Reduced fossil fuel supplies together with changing trends in modern housing developments, have led the consumer to investigate alternative methods of heating the home - Leaving Cert Home Economics - Question 1(a) - 2006
Step 1
Identify three heating options available for the modern home.
Answer
- Full Central Heating: This system uses a boiler to heat water, which is then circulated through radiators in each room.
- Partial Central Heating: Similar to full central heating, but may have some rooms without heating, often found in older homes.
- Passive Solar Heating: This method utilizes building design to maximize solar gain and reduce heating costs.
Step 2
Explain the factors which should be considered when choosing a heating system for a family home.
Answer
- Cost: Initial installation and ongoing fuel costs must be evaluated to ensure affordability.
- Safety: Safety features should be assessed, especially concerning potential hazards such as gas leaks or electrical issues.
- Space Heating Requirements: The system should adequately heat all spaces in the home.
- Convenience: Systems should be user-friendly and convenient to manage.
- Aesthetic Appeal: The visual impact of the heating system should align with home decor and design preferences.
Step 3
Set out details of one domestic central heating system you have studied. Include reference to:
Answer
- (a) Fuel/Energy Source: The Wet System utilizes water heated in a boiler, powered by gas or electricity.
- (b) Heating Principle: Water circulates through radiators, which release heat into the rooms via convection and radiation.
- (c) Efficiency and Convenience: This system allows for zoning, enabling rooms to be heated as required, which can enhance energy efficiency and comfort.
