Using Data Loggers to Verify Boiler Hot Water Reset

March 22, 2018 By SBC

A strategy to reduce heat loss from boiler water distribution systems is to reset the supply water temperature based on heating demand. Lowering the supply water temperature reduces the energy loss from the distribution system and saves energy. The most common method is to reset hot water supply temperature based on outside air temperature. This can easily be accomplished with stand-alone boiler temperature control systems. Buildings with Building Automation Systems (BAS) can also use a combination of outside air temperature and heating valve position to determine heating demand.

In either case, how can you determine if a hot water temperature reset schedule is in use and operating properly?  Read this technical document to learn how you can use data loggers to verify the performance of a hot water reset control.

Check out the many other technical resources that can also be found on SBC’s Tool Lending Library resources page.
