What APOLLO Floor Fan Coil FCU works with
Complete the system
What This Fan Coil Needs to Work
APOLLO Heat Pump
The heat pump that drives the system
Fan coils need hot or chilled water to run. Our Apollo air-to-water heat pumps supply that water — heating in winter, cooling in summer.
View details
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.
View details
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
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.

Frequently asked questions
What size floor fan coil unit do I need?
Estimated coverage guidance is 450–675 ft² for 1.5 Ton and 900–1,350 ft² for 3 Ton. Actual sizing depends on insulation, layout, climate, water temperature, and heat loss.
What are the heating and cooling capacities of the Apollo Vertical Floor Fan Coil Unit?
The 1.5 Ton model delivers 9,000 BTU cooling and 13,500 BTU heating at 300 CFM. The 3 Ton model delivers 18,000 BTU cooling and 27,000 BTU heating at 600 CFM. Actual output depends on entering water temperature and fan speed.
Can the Apollo Vertical Floor Fan Coil Unit be installed on the floor or mounted on a wall?
Yes. It includes floor support legs and can also mount to a wall using a separate support. Anchors, bolts, and nuts are not included.
Is the Apollo Vertical Floor Fan Coil Unit compatible with an air-to-water heat pump?
Yes. It connects to hot or chilled water from an air-to-water heat pump, boiler, or chiller through ½ in NPT fittings. Multiple units can share a common manifold or zone controller.
What thermostat works with the Apollo Vertical Floor Fan Coil Unit?
Remote control and thermostat are not included. Use a compatible 24VAC or 0–10VDC FCU thermostat. Each floor fan coil needs its own dedicated thermostat; multiple units cannot share one.
How quiet is the Apollo Vertical Floor Fan Coil Unit?
The 1.5 Ton model operates at 30–45 dB and the 3 Ton model at 35–50 dB, depending on fan speed.
Does the floor mounted fan coil unit use a 2-pipe or 4-pipe system?
Selectable 2-pipe and 4-pipe variants are available. Two-pipe systems share one hot-or-chilled loop; four-pipe systems use separate hot and chilled circuits.
What are the water connection and pressure requirements?
The unit uses ½ in NPT supply and return connections and is rated to 200 PSI. For cooling, insulate water inlet, outlet, and condensate piping to prevent surface condensation.
How does a vertical floor fan coil compare to wall-mounted or ceiling cassette FCUs?
Its upright cabinet sits low along a wall or floor line, making it useful under windows. Wall FCUs mount higher and are usually fastest to retrofit; ceiling cassettes mount flush and distribute air in multiple directions.
What is included with the Apollo Vertical Floor Fan Coil Unit, and what else will I need?
Each unit includes a washable filter and built-in condensate drain system. A compatible thermostat, supply and return piping, shut-off valves, and cooling-pipe insulation are separate.
