Review NORITZ Thermal Fuse New In Original Sealed Package

The Noritz SKH7189 is a high-performance thermal fuse designed for use with Noritz's line of condensing tankless water heaters. This thermal fuse plays a crucial role in ensuring the safe operation of your water heating system by protecting it against potential overheating issues.

The SKH7189 thermal fuse is engineered with a high-temperature limit setting of 185 F (85 C). Once the water temperature inside the heating chamber reaches this threshold, the thermal fuse will activate and interrupt the power supply to the heating element. This safety measure helps prevent the water from overheating, which could potentially cause damage to the water heater or pose a risk of scalding.

The thermal fuse is designed with a rugged, compact housing that can withstand the demanding conditions found in water heating applications. It features a quick-connect terminal block for easy installation and wiring, making it a straightforward addition to your Noritz water heater system.

The Noritz SKH7189 thermal fuse is also designed to be self-resetting. Once the water temperature has returned to a safe level, the thermal fuse will automatically reset and restore power to the heating element, allowing the water heater to resume its operation.

Overall, the Noritz SKH7189 thermal fuse is an essential component for ensuring the safe and efficient performance of your condensing tankless water heater. Its high-temperature limit setting, rugged design, and self-resetting capability make it a reliable and effective solution for safeguarding your water heating system against potential overheating issues.

The Noritz SKH7189 thermal fuse is a crucial safety component for Noritz tankless water heaters. It is designed to protect the system from overheating, which can cause damage to the heater and potentially lead to safety hazards. Here are some pros and cons of buying this thermal fure:

Pros:

1. Ensures safety: The primary function of a thermal fuse is to prevent overheating, which can cause damage to the water heater and potentially lead to safety hazards.

2. Easy to replace: If the thermal fuse fails, it can be easily replaced without having to replace the entire water heater.

3. Cost-effective: Replacing a thermal fuse is generally less expensive than replacing the entire water heater.

4. Long lifespan: Thermal fuses are designed to last for several years, providing reliable protection for the water heater.

Cons:

1. Single-use component: Once a thermal fuse has been triggered, it cannot be reset or reused. It must be replaced with a new one.

2. Potential for false trips: In some cases, thermal fuses can trip falsely, which can be inconvenient and require unnecessary replacement.

3. Limited availability: Thermal fuses may not be readily available at local hardware stores, which could require ordering from an online retailer or specialty supplier.

In conclusion, the Noritz SKH7189 thermal fuse is an essential safety component for Noritz tankless water heaters. While there are some potential drawbacks, such as the need to replace the fuse when it trips and the limited availability, the pros outweigh the cons. The thermal fuse provides reliable protection against overheating, is easy to replace, and is generally cost-effective compared to replacing the entire water heater. Therefore, it is recommended to have a spare thermal fuse on hand to ensure the continued safe operation of the water heater.
