3 Ton Heat Pump High-Temp Hydronic

The APOLLO MAX 3 ton heat pump is sold in the 36,000 BTU nominal capacity class and is built for high-temperature output up to 170°F. MAX is the right choice when baseboards, cast iron radiators, or other demanding emitters need hotter water than the standard APOLLO provides, especially in very cold weather. This is an air-to-water hydronic heat pump; actual output changes with outdoor and leaving-water temperature.

The general planning range for this 3 ton heat pump is Up to 2,000 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 MAX 3 ton suits homes up to about 2,000 ft² that use baseboards, cast iron radiators, or other high-temperature emitters, or that need hotter water in extreme cold. Choose the standard APOLLO instead for radiant floors and fan coils that run at lower water temperatures.

Compare the building's design heating and cooling loads with the 3 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 MAX operating range extends from -31°F to 110°F, and it is built to hold higher water temperatures in extreme cold for demanding emitters. Operating range does not mean full output at every temperature, so compare condition-specific output with the building load to decide whether backup or staged capacity is needed. Detailed MAX performance ratings are published in the technical manual.

Yes. The MAX series is designed for high-temperature hydronic systems and can deliver leaving-water temperatures up to 170°F. That makes it well suited to baseboards and cast iron radiators that need hotter water, as well as radiant floors and other low-temperature emitters. Confirm design temperatures and emitter output against the 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 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 42 dB(A). Its rated water flow is 8.2 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.
