The Square A6.20 Overload Heater Element FNOB (First Normal Operating Betting Limiter) is a safety device designed for electric water heaters to prevent overheating and potential electrical hazards. Here are some pros and cons of buying this heater element:

1. Safety: The primary advantage of the Square A6.20 Overload Heater Element FNOB is its safety feature. It automatically shuts off the power supply when the temperature exceeds the safe limit, preventing potential fires or electrical accidents.

2. Longer lifespan: By protecting the heating element from overheating, the FNOB can help increase the overall lifespan of the water heater.

3. Easy installation: The Square A6.20 Overload Heater Element FNOB is relatively easy to install, as it replaces the existing heating element in the water heater.

4. Cost-effective: Compared to the cost of replacing an entire water heater due to overheating damage, the cost of purchasing and installing an FNOB is a more cost-effective solution.

1. Initial cost: While the cost of an FNOB is less than the cost of a new water heater, it still requires an initial investment.

2. May not cover all causes of overheating: An FNOB only protects against overheating caused by electrical issues. It does not address other causes of overheating, such as insulation issues or sediment buildup in the tank.

3. Requires periodic testing: To ensure the FNOB is functioning properly, it should be periodically tested using a multimeter or test light.

In conclusion, the Square A6.20 Overload Heater Element FNOB is a worthwhile investment for electric water heaters, as it provides an additional layer of safety against potential electrical hazards and can help extend the lifespan of the heating element. However, it is important to note that it does not address all causes of overheating and requires periodic testing for proper functioning.

Recommendation: If you have an electric water heater and are concerned about potential electrical hazards or want to extend the lifespan of your heating element, consider purchasing and installing a Square A6.20 Overload Heater Element FNOB. However, it is also important to regularly maintain and inspect your water heater to address any potential issues that may contribute to overheating.
