R8182H

The Honeywell R8182H Aquastat High Limit Relay is a crucial component in ensuring the efficient and safe operation of residential and light commercial heating systems. This particular model, with the 1070 SID and also known as the Harveys R80-40R, is designed to protect against excessive temperature conditions that could potentially harm the system or its users.

This high limit relay is a compact, versatile device that can be easily integrated into various heating applications. It measures 4.4 inches long, 2.6 inches wide, and 1.3 inches high, making it a suitable fit for most standard installation spaces. The device is designed with a robust, industrial-grade construction, ensuring long-lasting performance even under heavy usage.

At the heart of this relay is a high-temperature sensor, which constantly monitors the temperature of the water or other heating media flowing through the system. When the temperature exceeds a predetermined threshold, the relay will automatically disconnect power to the heating element or circulator pump, preventing any further heat production and potentially costly damage.

The Honeywell R8182H is designed with user-friendliness in mind. It features a clear, easy-to-read temperature dial, allowing users to quickly set the desired temperature limit. The relay is also equipped with a test button, allowing for simple and convenient verification of its proper functioning.

This high limit relay is designed for use with a wide range of heating systems, including hydronic heating, radiant floor heating, and baseboard heating. It is suitable for applications with heating media temperatures ranging from 140 F to 275 F (60 C to 135 C).

The Honeywell R8182H is CE marked, ensuring compliance with European Union safety standards. It is also RoHS compliant, meaning it contains no restricted hazardous substances. This makes it an environmentally-friendly option for those seeking to minimize their carbon footprint.

In summary, the Honeywell R8182H Aquastat High Limit Relay is a vital and versatile component for any heating system, designed to ensure safe and efficient operation while providing ease of use and long-lasting performance. Its compact size, robust construction, and wide temperature range make it a suitable choice for a variety of heating applications.

Comparison of Honeywell R8182H and Harveys R80-40R Aquastats with High Limit Relays

The Honeywell R8182H is a two-wire temperature control device designed for use with heating systems. It features a high limit relay with a setting range of 105 F to 165 F (40.6 C to 73.9 C). This aquastat is suitable for both residential and commercial applications.

- Wide range of high limit setting options

- Durable construction

- Easy to install

- Compatible with various heating systems

- Reliable performance

- Higher price point compared to some alternatives

- Limited temperature sensing range (80 F to 140 F or 26.7 C to 60 C)

The Harveys R80-40R is also a two-wire temperature control device, but it comes with an integrated high limit relay with a setting range of 105 F to 165 F (40.6 C to 73.9 C). This aquastat is commonly used for both hot water and steam heating applications.

- Integrated high limit relay

- Durable construction

- Easy to install

- Wide range of high limit setting options

- Suitable for various heating systems

- Limited temperature sensing range (80 F to 140 F or 26.7 C to 60 C)

- Slightly lower reliability compared to Honeywell R8182H

Both the Honeywell R8182H and Harveys R80-40R aquastats offer similar features, including wide range high limit settings and compatibility with various heating systems. The primary difference is the integrated high limit relay in the Harveys R80-40R, which could be a convenience factor for some users. However, the Honeywell R8182H generally has a better reputation for reliability.

If reliability is your top priority, we recommend the Honeywell R8182H. However, if you prefer the convenience of an integrated high limit relay, the Harveys R80-40R is a suitable alternative. Ultimately, your decision may depend on your specific application requirements and personal preferences.
