APOLLO Air-to-Water Heat Pump - 5 Ton - 60K BTU

The APOLLO 5 ton heat pump is sold in the 60,000 BTU nominal capacity class. Heat pump tonnage describes heating and cooling capacity, not the unit's physical weight. This is an air-to-water hydronic heat pump, not a conventional ducted air conditioner or condenser. Actual output changes with outdoor temperature and leaving-water temperature.

The general planning range for this 5 ton heat pump is 2,500 to 4,000 ft². This is a starting point, not a substitute for load calculations. Climate, insulation, windows, ceiling height, air leakage, required water temperature, and indoor distribution all affect the capacity a building needs.

The 5 ton APOLLO is the middle-capacity option, with a general planning range of 2,500 to 4,000 ft². Choose it when calculated loads exceed the 3.5 ton model's condition-specific output but do not require the 6 ton model or multiple staged units.

Compare the building's heating and cooling needs with the 5 ton heat pump output under local winter and summer conditions. Also consider the required system water temperature, indoor equipment, domestic hot water or pool heating, and whether backup heat or additional heat pumps may be needed.

Yes. The APOLLO can supply heated water to radiant floors, fan coils, or compatible air handlers. For cooling, it supplies chilled water to fan coils or air handlers designed for cooling and dehumidification. Radiant-floor cooling requires dew-point and condensation controls and should only be used in a properly engineered system.

The APOLLO operating range extends from -31°F to 110°F, but operating range does not mean full output remains available at every temperature. At the manual's 10°F heating test condition, this model produces approximately 32.4 KBTU with a COP of 2.13. Compare condition-specific output with the building load to determine whether backup or staged capacity is needed.

It can serve as the main hydronic heat source when its condition-specific output and maximum leaving-water temperature of up to 131°F match the building and its emitters. Radiant floors and other low-temperature systems are strong applications. High-temperature radiators or baseboards must be checked carefully before replacing a boiler.

Yes, when paired with the correct indirect domestic-hot-water tank, pool heat exchanger, piping, and controls. The outdoor heat pump does not provide tankless domestic hot water by itself. Tank recovery, system priority, pool load, and simultaneous space-heating demands must be included in the system design.

A complete system may include the outdoor heat pump, Hydro Station, household hot-water tank, buffer tank, water pumps, controls, expansion tank, components that remove air and debris from the water loop, electrical protection, and indoor heating or cooling equipment. Exact parts depend on the installation.

Published performance reaches a COP of up to 5.65 under favorable test conditions, but that is not a year-round guarantee. COP changes with outdoor temperature, water temperature, load, flow, and system design. Use the condition-specific performance tables when estimating operating efficiency.

The product price shown on this page covers the selected equipment configuration, not necessarily a complete installed hydronic system. Total project cost depends on tanks, controls, indoor distribution, electrical work, piping, labor, and project complexity. A system plan is needed for a meaningful installed-cost estimate.

This model uses 220–240V / 1 / 60Hz power and has a published sound level of 55 dB(A). Its rated water flow is 13 GPM through a 1 in water connection. Electrical protection, piping, clearances, freeze protection, startup, and local-code requirements must be confirmed from the current installation manual by qualified professionals.
