HHW System Cycling Manager
Provided by Greffen Systems
The Problems:
1) HHW Boilers must be sized for the most extreme conditions in order to ensure adequate heating throughout the year. This creates wide fluctuations in demand, with boilers often running in low load conditions.
2) Due to the low demand and fluctuating needs of a building, rapid cycling is a reality for the vast majority of HHW closed loop boiler systems, often involving hundreds of cycling instances each day.
3) Rapid firing is highly wasteful, as each firing cycle requires a purge of existing gas in the boiler tubes, wasting energy with each cycle.
4) Standard controls on HHW systems do not provide tight temperature management of the heating hot water loop, creating waste in both gas consumption and increased carbon emissions.
The Product:
1 - Energy Usage Savings: The M2G is designed specifically to reduce boiler cycling, reducing this wasteful process by up to 65% in HHW boiler closed loop systems. The dramatic reduction in boiler cycling translates into an average gas usage savings of 10-20% across thousands of installations.
2 – M&O Savings: Boiler short-cycling can be extremely detrimental to the lifespan and functionality of the boiler. Reducing the daily cycling can extend boiler life, as well as reduce associated maintenance and operational costs.
3 – Carbon Emissions Reduction: Carbon reduction is a national benefit of gas savings, with similar savings being realized as an added benefit to the environment.
4 – Monitoring and Validation: The M2G has an optional monitoring system to track the cycling and other characteristics of the boiler, adding valuable information for the site to help manage the health and operation of the boiler.
The Competitive Advantage:
The M2G has a significant competitive advantage in the boiler controller market, focusing exclusively on boiler cycling and providing a unique value proposition that has been confirmed by the DOE, The Gas Institute, and some of the largest corporations in facilities around the world.
