This sensor plays a critical role in the heater s control system by continuously monitoring the temperature of the water supply, enabling the boiler or heating unit to maintain precise thermal regulation with minimal energy waste. Crafted with Bosch s signature engineering excellence, the 83QSZH87 is built to withstand the demanding conditions of high-pressure water systems while delivering accurate readings within a temperature range of approximately **0 C to 100 C (32 F to 212 F)**, making it ideal for both domestic hot water heating and hydronic radiant floor systems. Constructed from durable, corrosion-resistant materials, including a robust stainless-steel housing and a high-grade thermistor element, this sensor is designed for long-term durability, reducing the risk of failure and ensuring consistent performance even in harsh environments. Its compact yet robust design allows for seamless installation within the Enclave series compact control modules, where space efficiency is paramount. The sensor s digital output interface ensures compatibility with the heater s advanced control board, facilitating real-time feedback that optimizes heating cycles, prevents overheating, and extends the lifespan of the entire system. Whether used in a modern, energy-efficient home or a commercial setting requiring reliable hot water delivery, the Bosch 83QSZH87 sensor exemplifies Bosch s commitment to innovation and precision, delivering a balance of performance, durability, and ease of integration that enhances the overall functionality of the Enclave Lacrosse, Lucerne, and Regal water heaters.

### **Bosch 83QSZHS87 Water Temperature Sensor for Enclave Lacrosse (Lucerne, Rainier, Regal) Pros and Cons**

1. **Compatibility** The Bosch 83QSZHS87 is a direct replacement for the original water temperature sensor in Enclave Lacrosse models (Lucerne, Rainier, Regal), ensuring a seamless fit without modifications.

2. **Reliability** Bosch is a well-known brand in automotive and HVAC components, offering durable and long-lasting sensors that reduce the risk of frequent failures.

3. **Easy Installation** The sensor is designed for straightforward replacement, requiring minimal tools and technical skill. Most users can install it themselves without professional help.

4. **Cost-Effective** While not the cheapest option, it is often more affordable than OEM sensors and provides better long-term reliability than generic aftermarket alternatives.

5. **Improved Performance** A properly functioning water temperature sensor ensures accurate engine temperature readings, which helps maintain optimal engine performance, fuel efficiency, and cooling system operation.

6. **Warranty Coverage** Bosch sensors typically come with a manufacturer warranty (varies by retailer), providing some protection against defects.

7. **Prevents Coolant System Issues** A faulty sensor can lead to overheating, coolant leaks, or even engine damage. Replacing it proactively can prevent costly repairs.

1. **Price** While reasonable for a Bosch part, it may still be more expensive than some no-name or generic sensors, though the trade-off is better quality.

2. **Limited Availability** Depending on the retailer, stock levels for this specific part may vary, requiring advance ordering or checking multiple suppliers.

3. **Installation Complexity (If DIY Unfamiliar)** Though generally simple, those unfamiliar with automotive repairs might struggle with accessing the sensor (located near the thermostat housing) or ensuring a proper seal.

4. **Potential for Counterfeit Parts** Purchasing from untrusted sellers (e.g., third-party Amazon vendors) could result in fake or low-quality replicas, which may fail prematurely.

5. **Thermostat Replacement May Be Needed** If the sensor is failing due to a failing thermostat or coolant system issues, replacing just the sensor may not fully resolve the problem, requiring additional work.
