VH Engine Heater
Hotstart’s VH thermosiphon heating system is a coolant preheater, developed to maintain optimal temperatures for diesel and gas engines in power generation, fire pump, marine, construction equipment, and truck applications. Depend on consistent, reliable heating with the proven design of the VH thermosiphon heater. Heated coolant rises and circulates through the engine block, maintaining critical system temperatures during standby to ensure reliable engine starts.
The VH can be configured for almost any weather-protected application. Dual thermostats are integrated for fixed temperature monitoring as well as a high limit for safety. Multiple options are available for this CE and UKCA compliant design. The VH’s inlet and outlet positions allow for quick and simple installations, reducing complicated plumbing requirements. Each VH comes with a universal mounting kit for quick and easy upgrading from existing heater installations.
