Energy Efficient Heaters

With energy efficiency being top of mind for businesses around the world, Sustainability Managers are tasked with optimizing onsite equipment with the goal of reducing electrical usage. Backup power generators are a prime target, as they often sit idle for the vast majority of their service life with their main power draw being the engine heater continuously running to maintain engine starting temperature.

By installing Hotstart Energy Efficient heaters on their generators, data centers, hospitals, banks, hotels and other essential industries can maximize their sustainability efforts. Upgrading an existing standard convection engine block heater to a pump-driven model can result in an immediate reduction in energy usage. Hotstart offers two energy efficient pump-driven heater solutions -- HOTflow and EVRHEAT -- covering generator engine sizes from 20 to 100 liters.  

HOTflow®

HOTflow forced circulation engine heaters feature an integrated pump that circulates warm coolant throughout the entire engine at uniform temperatures. Constant circulation of the coolant eliminates hotspots that can deteriorate heater hoses, harm engine seals, and diminish coolant life. HOTflow engine heaters rely on fewer heating cycles — saving up to 35% in energy consumption while extending heater element life and reducing maintenance work.

EVRHEAT®

EVRHEAT forced circulation heaters are designed and built with efficiency, versatility, and reliability in mind. Integrated controls and sensors monitor the status of the heater and send signals to an LED display to show current heater operation. At-a-glance, operators can see if the EVRHEAT is operating normally or needs service. Installation is simplified with a swivel inlet hose barb that moves 180° in either direction to accommodate plumbing in confined areas. Retrofiting the EVRHEAT into existing installations is quick and easy and operators looking to reduce their energy consumption of their standby generator heater can see up to 45% energy savings  with EVRHEAT compared to standard thermosiphon heaters.
