Complete the system
An air-to-water heat pump is the heart of a full hydronic system. These are the parts that complete it and what each one does. We confirm exactly what your home needs before you buy.
Hydro Station
A simpler mechanical room
Combines pumps, controls, and backup heat into one compact wall station, reducing loose parts and installation labor.
View details
Domestic hot water
Hot water from the same heat pump
A combined buffer and indirect tank lets the heat pump make household hot water, with no separate water heater needed.
View details
Radiant floor distribution
Even heat across every zone
Distributes and balances warm water to each radiant loop so rooms heat evenly and stay easy to control.

Heating & cooling delivery
Fan coils for forced-air comfort
Wall, concealed, ceiling, or floor units heat and cool rooms with the same water. Pick the style that fits each space.
View details
Zone controls
Universal thermostat for fan coil & radiant
One WiFi thermostat runs fan coils or radiant floors and tells the system to work only when there is real demand.

Product FAQ
Direct answers about 5 ton heat pump capacity, sizing, cold-weather performance, hydronic applications, efficiency, and installation planning.
The APOLLO MAX 5 ton heat pump is a 60,000 BTU system that uses R290 refrigerant, which has very low climate impact if released. Choose the right capacity by matching the heat pump's output to the building's calculated heating and cooling loads. It can supply water temperatures up to 170°F when required, but using the lowest practical water temperature reduces electricity consumption.
The general planning range for this 5 ton heat pump is Up 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.
Yes. The R290 MAX 5 ton serves larger homes and hydronic projects, with a general planning range up to about 4,000 ft². Larger loads may require multiple units or staged capacity, confirmed by a load calculation.
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 MAX operating range extends from -31°F to 110°F and supports cold-climate hydronic heating. Operating range does not mean full output at every temperature, so compare condition-specific capacity and efficiency with the building load to determine whether backup or staged capacity is needed. Detailed MAX performance ratings are published in the technical manual.
Yes. APOLLO MAX supports radiant floors and other low-temperature hydronic emitters, where lower supply-water temperatures generally improve heat-pump efficiency. It can also deliver leaving-water temperatures up to 170°F for compatible systems when required. Confirm the design temperature, emitter output, and building load 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.
APOLLO MAX uses R290 refrigerant and is designed to reduce annual electricity consumption by approximately 10% compared with comparable R32 systems. Actual savings depend on climate, building load, supply-water temperature, flow, controls, and overall system design. Operating at the lowest practical supply-water temperature helps maximize 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 48 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.
Current model
60,000 BTU / 5 Ton · Up to 4,000 ft². Larger homes up to 4,000 ft² seeking efficient water-based heating, cooling, and hot water with R290 refrigerant and very low climate impact.
Property-size ranges are planning guides only. Final model selection requires a heat-loss or load calculation that accounts for climate, insulation, air leakage, windows, water temperature, and system application. Actual output changes with outdoor air and leaving-water temperature.
