Ilios heat pump Energy ManageIlios Dynamics, a subsidiary of Tecogen, has introduced the Ilios HEWH-500-AS Split System air-sourced natural gas driven heat pump water heater. The new product cuts water heating costs in half, according to the company.

The split system allows a significant portion of the machine to be installed inside the mechanical room, making it less expensive to install and easier to service.

The Ilios HEWH-500-AS Split System consists of two pieces of equipment, an engine-driven heat pump portion, which is contained in a small acoustic enclosure within the building’s mechanical space, and a remote air-source evaporator package, which can be placed outside the mechanical room. The remote evaporator has minimal service needs so it can be placed in areas that are difficult to access. The indoor component is packaged in a 3-ft. by 5-ft. enclosure to ease retrofitting into existing mechanical spaces. The outdoor component includes noise reduction measures to ensure its fans operate quietly.

The outdoor component is connected via refrigerant lines, eliminating freeze protection issues in colder climates. All of the water being heated remains inside the conditioned space, so there is no need for a heat exchanger and additional pumps.

Tecogen said the product is ideal for urban areas in colder climates that have a significant need for hot water.
