A space heater with 100% efficiency would convert all the electrical energy it consumes into heat, making it extremely efficient. This means that all the energy input is converted into useful output, with no waste. However, it's important to note that achieving 100% efficiency in real-world devices is extremely difficult due to factors such as heat loss and other inefficiencies in the system. **

The best heater for you will depend on your specific needs and preferences. Consider factors such as the size of the space you need to heat, your budget, and whether you prefer a portable or fixed heater. Electric heaters are often a popular choice for their ease of use and efficiency, while propane heaters are a good option for outdoor spaces or areas without access to electricity. Ultimately, it's important to choose a heater that meets your heating requirements and fits within your budget. **

The cheapest infrared heater/electric heater can vary depending on the brand, model, and features. However, some of the most affordable options include compact infrared space heaters or basic electric fan heaters. These types of heaters are often designed for small spaces and can be found at budget-friendly prices. It's important to consider the heating capacity, energy efficiency, and safety features when choosing a budget-friendly infrared or electric heater. **

No, it is not true that an electric heater always has an efficiency of 100%. While electric heaters can convert nearly all of the electrical energy they consume into heat, they still experience some energy loss due to factors such as heat dissipation through the materials of the heater and heat loss to the surrounding environment. Therefore, the efficiency of an electric heater is typically very high, but not 100%. **
