6 Ton Heat Pump Air-to-Water

The APOLLO 6 ton heat pump is sold in the 72,000 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 6 ton heat pump is 4,000 to 6,000 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 APOLLO 6 ton heat pump can serve large residential and light-commercial hydronic projects. Its general planning range is 4,000 to 6,000 ft², subject to load calculations. Larger buildings or higher loads may require multiple heat pumps or staged capacity.

Compare the building's design heating and cooling loads with the 6 ton heat pump output at the local design temperature and required leaving-water temperature. The system design should also account for radiant floors, fan coils, air handlers, zones, domestic hot water, pool heating, and any backup or staged heat source.

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 39.2 KBTU with a COP of 2.11. 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 hydronic system may include a Hydro Station, indirect domestic-hot-water tank, buffer tank, circulators, controls, expansion equipment, air and dirt separation, electrical protection, and radiant, fan-coil, or air-handler distribution. The exact bill of materials depends on the application and piping layout.

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 58 dB(A). Its rated water flow is 19.2 GPM through a 1 1/4 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.
