Goodman 80000 BTU 80% Multi-Speed Upflow Furnace GR9S800803BX

Description

Product Overview

The Goodman GR9S800803BX is a high‑performance furnace engineered for demanding laboratory and scientific environments. Rated at 80,000 BTU (6.67 tons) and 80 % seasonal energy efficiency, it balances powerful heating output with energy‑saving operation. Housed in a compact 17.5‑inch wide cabinet (33.38 x 17.5 x 33.38 inches), the unit fits into tight ceiling or floor spaces while maintaining full upflow or horizontal airflow pathways. The furnace features a single‑stage, multi‑speed ECM (electronically commutated motor) that modulates airflow in real time, delivering precise temperature control, reduced acoustic noise, and lower operating costs. A durable aluminized steel primary heat exchanger ensures even heat distribution and long‑term reliability. Remote‑controlled operation, optional liquid propane (LP) conversion kits, and a range of compatible thermostats make the GR9S800803BX a versatile solution for labs, research facilities, and small commercial spaces.

Usage

This furnace is designed for environments where temperature stability is critical. Ideal applications include university chemistry labs, biomedical research suites, pharmaceutical testing chambers, and quality‑control facilities that require consistent heating without temperature spikes. The upflow configuration directs warm air upward, perfect for ceiling‑mounted installations where space is limited. Horizontal installation options allow integration into wall or floor ducts, providing flexibility for retrofits or new builds. The unit’s 115‑volt power requirement aligns with standard laboratory electrical infrastructure, and its remote‑control capability enables centralized monitoring across multiple workstations. Whether maintaining a constant 70 °F for a cell culture incubator or providing rapid heat‑up for a materials testing chamber, the GR9S800803BX delivers reliable performance.

FAQ

Can this furnace be installed as a downflow unit?

No. The GR9S800803BX is engineered for upflow or horizontal installation only. For downflow applications, Goodman offers the GD9 series, which is specifically designed for that airflow direction.

What is the benefit of the ECM motor compared to a traditional PSC motor?

The ECM motor uses electronic commutation to adjust speed continuously, providing higher efficiency, lower noise, and finer temperature control. It also reduces wear on components, extending the furnace’s service life.

Is a propane conversion kit available for this model?

Yes. An optional LP (liquid propane) conversion kit can be purchased separately, allowing the furnace to operate on propane where natural gas is unavailable.

What remote control options are compatible?

The furnace works with Goodman’s line of Wi‑Fi thermostats and standard 4‑wire thermostats. Remote control enables temperature adjustments from a central console or mobile device.

How does the furnace meet current environmental standards?

The unit uses R‑32 refrigerant, which has a low global warming potential, and its design meets low‑NOx emission requirements, ensuring compliance with modern environmental regulations.
