Assertion (A): Heat pump used for heating is a definite advancement over the simple electric heater.
Reason (R): The heat pump is far more economical in operation than an electric heater.
Explanation:
A heat pump is a device that transfers heat from a colder area to a warmer area by using mechanical energy. It can be used for both heating and cooling purposes. On the other hand, a simple electric heater converts electrical energy into heat energy to warm up a space.
Heat Pump Advantages:
1. Energy Efficiency: Heat pumps are more energy-efficient compared to electric heaters. They use a small amount of electricity to transfer heat rather than generating it directly. This makes them more economical to operate.
2. Environmental Impact: Heat pumps have a lower carbon footprint as they rely on renewable or low-carbon electricity for operation. Electric heaters, on the other hand, directly consume electricity, which may be generated from fossil fuels.
3. Versatility: Heat pumps can provide both heating and cooling, making them a versatile option for maintaining a comfortable indoor temperature throughout the year.
4. Longer Lifespan: Heat pumps generally have a longer lifespan compared to electric heaters. With proper maintenance, a heat pump can last up to 20 years or more, while electric heaters typically have a shorter lifespan.
Economic Advantages of Heat Pumps:
1. Lower Operating Costs: Heat pumps are more efficient in converting energy into heat, resulting in lower operating costs compared to electric heaters.
2. Reduced Energy Consumption: Heat pumps use less energy to produce the same amount of heat as electric heaters, resulting in lower energy bills.
3. Government Incentives: In many countries, there are government incentives and rebates available for installing heat pumps due to their energy-efficient nature. This further reduces the overall cost of owning and operating a heat pump.
Conclusion:
Both the assertion and the reason are true. The heat pump is indeed a definite advancement over the simple electric heater as it offers energy efficiency, environmental benefits, versatility, and a longer lifespan. The reason provided for this assertion is also correct, as the heat pump's economical operation is one of its key advantages over electric heaters. Therefore, option A is the correct answer.
Reason (R): The heat pump is far more economical in operation than an electric heater.
