Hotstart

Founded in 1942 and based in Spokane, Hotstart is the world leader in the design and manufacture of engine heaters for backup generators and is the leading supplier to generator OEMs. Backup generators are found in critical buildings such as data centers, hospitals, airports, universities, arenas, prisons, office buildings and industrial buildings. The generator block heater runs 24/7 so the generator can start any time with full power in the event of a power outage. The traditional heater (made by Hotstart or others) on a 1MW+ generator uses electric resistance elements consuming up to 60MWh of electricity annually. Hotstart is the world leader in retrofitting these heaters with proven air-source heat pump technology to reduce energy consumption up to 75% while adding redundancy, reducing maintenance, and improving sustainability.
