TAKE CONTROL OF YOUR DISTRIBUTION HEAT LOSSES

Research funded by the California Energy Commission show that central DHW systems in multifamily buildings waste an average of 70% of the total energy that is put into them

Roughly one-third of the total energy is lost in the recirculation loop, with excessive recirculation flow being a major contributor.

AutoHot commercial control systems specifically address these energy losses and can combine control strategies to optimize hot water distribution, savings energy, reducing wear and tear on the system and increasing the useful life of your equipment.  Commercial AutoHot controls include:

Demand Recirculation Controls– The commercial AutoHot DC series demand control provides recirculation pumps with controls that regulate the run time of the pump based on demand and temperature sensors.  Keep in mind that these are different from the residential version, which use push buttons and motion sensors to activate the system.  This uses a combination of ultra sensitive flow and temperature sensors and a timed sequence that we call ‘AutoPrime’ to reduce pump run time, distribution heat losses and increase overall water heating efficiency by as much as 30%, while preserving the service of hot water to occupants in the building.
