## Summary description

The Kalvis Honeywell draft regulator is a mechanical device designed to control the combustion air supply in solid fuel boilers. By automatically adjusting the air intake flap based on the boiler water temperature, it ensures optimal combustion efficiency, stable heat output, and fuel savings. This reliable regulator is essential for maintaining consistent boiler performance and safe operation in heating systems.

## Long description

The Kalvis Honeywell draft regulator is a precision mechanical device engineered to manage the combustion air supply for solid fuel boilers. By monitoring the boiler water temperature, the regulator automatically adjusts the air intake flap, ensuring that the combustion process remains efficient and stable. This device plays a critical role in maintaining consistent heat output while promoting fuel economy and enhancing the overall safety of your heating system.
Advantages
This regulator offers a robust mechanical design that operates independently of electrical power, ensuring reliability even during power outages. By maintaining a precise water temperature, it prevents overheating and reduces the frequency of manual adjustments required by the user. The integration of high-quality components ensures long-term durability and consistent performance, which directly contributes to a more efficient burn rate and reduced fuel consumption over the heating season.
Suitable for
Solid fuel boilers using wood, coal, or briquettes
Residential and commercial central heating systems
Upgrading existing boiler installations for better temperature control
When it may not be suitable
This device is not compatible with gas, oil, or electric boilers, as it is specifically designed for mechanical air intake control in solid fuel combustion chambers. It may also not be suitable for boilers that already feature integrated electronic combustion management systems.
Key specifications
Mechanical temperature-based operation
Adjustable temperature range for precise control
Durable construction for high-temperature environments
Compatible with standard solid fuel boiler air intake flaps
How to use
Installation involves mounting the regulator into the designated port on the boiler body, ensuring the sensing element is fully immersed in the boiler water. Once installed, the chain is connected to the air intake flap. The user then sets the desired water temperature on the regulator dial. As the water heats up, the internal thermostat expands, pulling the chain to close the flap and restrict air intake, thereby slowing the combustion process.
What to consider before purchase
Verify the thread size and mounting port compatibility on your boiler
Ensure there is sufficient clearance for the lever and chain mechanism
Check if your boiler model requires a specific orientation for the regulator
Usage recommendations
Regularly inspect the chain tension and the movement of the air intake flap to ensure there is no mechanical obstruction. Periodically calibrate the temperature setting to match the actual water temperature indicated by the boiler thermometer for optimal performance.
