What This Fan Coil Needs to Work
A fan coil circulates hot or chilled water — it cannot run on its own. Here are the three components that typically complete a fan coil install.
APOLLO Heat Pump
The heat pump that powers this unit
Fan coils circulate hot or chilled water — they cannot run on their own. Our Apollo air-to-water heat pumps supply that water and drive heating in winter and cooling in summer.

APOLLO Wi-Fi Thermostat
Smart control for every room
A dedicated fan coil thermostat runs the unit on a schedule and only when there is real demand, reducing energy use and improving room-by-room comfort.

Multi-zone install
Two fan coils, one heat pump
The Y-connector lets two fan coil units share a single heat pump circuit, expanding whole-home coverage without adding a second outdoor unit.

We Sell More Than Fan Coils
Many customers start with a fan coil and end up building a complete hydronic system. See everything we carry to heat, cool, and supply hot water from one outdoor unit.
Hydro Station
A simpler mechanical room
Combines pump, controls, and electric backup into one compact wall station — less loose parts, faster install, cleaner mechanical room.

Water Heater Tank
Hot water from the same system
The combined buffer and indirect tank lets the heat pump supply household hot water with no separate water heater needed.

Manifold Station
Add radiant floors to the same heat pump
Distributes warm water evenly to each radiant floor loop. Fan coils and radiant can both run from a single outdoor unit.

Ceiling-Mounted Design
Suspends from the ceiling to preserve valuable floor space in warehouses, workshops, and other large facilities.
-
Rapid Heat Dispersion
A powerful integrated fan helps distribute heat evenly and reduce hot spots throughout the space.
-
Efficient Heat Transfer
Its advanced heat exchanger design maximizes heat transfer efficiency to improve overall boiler performance.
-
Overheat Prevention
An automatic temperature-sensitive valve channels excess heat through the exchanger to help protect the boiler from overheating.
-
Durable, Low-Maintenance Build
Constructed with corrosion-resistant materials to handle demanding conditions while reducing ongoing maintenance needs.
Efficient Heat Dispersion
The integrated fan rapidly disperses heat for more even space heating, while the exchanger design supports better transfer efficiency and energy-conscious operation.
Automatic Protection
The FCU uses an automatic temperature-sensitive valve to divert excess heat and help prevent boiler overheating, improving safety and system longevity.
Space-Optimizing Design
Its ceiling-suspended layout frees up floor area, making it a practical choice for industrial, commercial, and other large-scale heating applications.
Robust & Versatile Applications
Built for warehouses, workshops, factories, and large commercial spaces, this FCU combines corrosion-resistant construction with dependable supplemental heating performance.

Commercial Fan Coil FAQ
APOLLO Commercial Fan Coil Frequently Asked Questions
Answers about sizing, heat capacity, boiler protection, electrical requirements, and best-fit spaces for the Apollo commercial fan coil unit.
What sizes does the Apollo Commercial Fan Coil Unit come in?
The Commercial FCU is available in 12x12, 18x18, 24x24, 30x30, and 36x36 sizes (36x36 also offered in a 240V/3PH option), with estimated coverage from about 550 ft² on the smallest size up to 8,800 ft² on the largest. Actual sizing depends on ceiling height, insulation, layout, and heat loss.
Does the commercial fan coil unit provide cooling, or heating only?
The Apollo Commercial FCU is a heating-focused unit, built primarily for space heating and dissipating excess heat from a hydronic boiler system across large areas. It is not designed as a cooling unit the way Apollo's residential wall, floor, and ceiling FCUs are.
What does the automatic temperature-sensitive valve do?
It's a built-in safety feature that automatically channels excess heat through the unit's heat exchanger when boiler water temperature rises, helping protect the boiler from overheating and extending the life of the overall hydronic system.
What electrical supply does the commercial FCU require?
Electrical requirements scale with unit size: 120VAC/60Hz on the 12x12, 18x18, and 24x24 sizes, and 240VAC/60Hz on the 30x30 and 36x36 sizes, with a 240V/3PH option available on the 36x36. Confirm the exact requirement for your selected size before wiring.
How much airflow and heat output can I expect?
Across the size range, the Commercial FCU delivers 600 to 5,000 CFM of airflow and 17,060 to 177,431 BTU/h of heat capacity, with larger sizes producing proportionally more airflow and heat output for bigger spaces.
What spaces is the commercial fan coil unit best suited for?
It's built for warehouses, workshops, factories, garages, and other large commercial or industrial spaces where a central hydronic boiler needs help distributing heat evenly. The ceiling-suspended design keeps the floor clear for equipment, storage, or vehicle traffic.
What boiler and piping systems is it compatible with?
The Commercial FCU is designed for integration with standard hydronic boiler and piping systems, using its integrated fan and heat exchanger to distribute hot water heat as forced air. Consult your installer to confirm piping and control compatibility with your specific boiler setup.
How durable is the commercial FCU, and how much maintenance does it need?
It's built with corrosion-resistant materials to withstand demanding warehouse and industrial conditions, and is designed to be low-maintenance so it can run reliably with minimal upkeep in continuous commercial service.
How is the commercial FCU different from Apollo's wall, floor, or ceiling fan coil units?
Apollo's wall, floor, and ceiling FCUs are residential-scale units designed for room-by-room heating and cooling comfort. The Commercial FCU is a larger, heating-only unit built specifically for large-area supplemental heating and excess boiler heat dissipation in warehouses, workshops, and factories, not for zone-by-zone residential climate control.
What is included, and what will I need for installation?
The unit ships ready for ceiling-suspended mounting and hydronic connection. You will need compatible boiler piping, appropriate electrical supply for your chosen size, and suspension hardware rated for the unit's weight. Given the size and ceiling-suspended mounting, installation by a qualified technician is recommended.
