R11020103

The Laars R11020103 Draft Diverter is a critical component in heating systems designed to prevent backflow of air and drafts, ensuring optimal performance of the boiler. This diverter is engineered with high-quality materials to provide durability and reliability, making it a popular choice among heating professionals.

The R11020103 Draft Diverter is designed for use with Laars heating boilers and is specifically engineered to fit the R Series models. It features a unique, patented design that utilizes a 3-inch inlet and a 1-inch outlet, allowing for seamless integration into the heating system.

The diverter is constructed from heavy-duty, cast iron material, which provides superior strength and durability. The cast iron body is coated with a high-temperature, corrosion-resistant finish, ensuring that the diverter can withstand the harsh conditions of a heating system.

The inlet and outlet connections are threaded for easy installation and are compatible with standard pipe sizes. The diverter also includes a built-in temperature gauge, allowing users to monitor the temperature of the water entering the diverter. This feature can help identify potential issues and ensure that the heating system is operating at peak efficiency.

The R11020103 Draft Diverter is designed to automatically switch the flow of water based on temperature differentials. When the water temperature at the inlet is cooler than the water temperature at the outlet, the diverter will automatically switch the flow, diverting the water away from the boiler to prevent drafts and maintain optimal boiler performance.

The diverter is also designed to prevent backflow of air into the heating system. This is accomplished through the use of an integrated air eliminator, which removes any trapped air from the water as it enters the diverter. This feature ensures that the heating system remains free of air, which can cause noise and reduce system efficiency.

In summary, the Laars R11020103 Draft Diverter is an essential component in maintaining the optimal performance of a heating system. Its heavy-duty construction, built-in temperature gauge, and automatic switching capabilities make it a reliable and effective solution for preventing drafts, backflow of air, and ensuring efficient heating system operation.
