Lochinvar® Corp. introduced package water heater and boiler systems that can be delivered to a job site piped and ready to install. When a water heater from the company is paired with a Lock-Temp tank from the company, the package system is pre-engineered, factory-assembled on an I-beam frame, and delivered fully assembled with all piping needed for the specific application. A contractor just has to link gas, electric and water piping to the system.
