PHNIX Introduces GreenTherm One All-In-One Heat Pump for One-Hour Heat Pump Installation

Guangzhou, 2 November 2026 — PHNIX introduces GreenTherm One, an all-in-one R290 heat pump designed to simplify residential installation. Combining space heating, cooling and domestic hot water in one outdoor unit, GreenTherm One features a built-in thermal storage tank that reduces on-site piping and the need for separate indoor equipment.

The integrated design supports faster installation while saving indoor space, making GreenTherm One a practical option for both new-build and renovation projects.

Fewer Components, Faster Installation

A residential heat pump installation often requires multiple components, pipe connections and space inside the home. GreenTherm One brings key components together in a single outdoor unit to simplify system planning and on-site work.

Its built-in thermal storage tank reduces the amount of piping needed during installation. The system is designed for a one-hour setup, helping installers complete projects more efficiently.

Thermal Storage with Fresh Hot Water on Demand

The built-in tank stores thermal energy rather than potable water. When hot water is needed, fresh water is heated as it flows through the system, providing domestic hot water on demand.

Because potable water is not stored in the tank, the flow-through design helps reduce the risk of Legionella. Under normal operating conditions, no additional anti-Legionella cycle is required.

The result is an integrated system that combines thermal storage with fresh hot water preparation, without requiring a separate indoor hot water tank.

Heating, Cooling and Energy Management in One System

GreenTherm One provides space heating, cooling and domestic hot water from one outdoor unit. It uses R290 refrigerant and includes protection measures for the water circuit.

The system also incorporates PHNIX AI technology. AI Full Inverter adjusts compressor operation to match changing demand, while AI Smart Grid supports heating plans around electricity tariffs. With the optional iDrive Box, AI PV Drive can coordinate heat pump operation with solar energy.

A Simpler Way to Deliver Residential Heat Pumps

For brands, distributors and installers, GreenTherm One brings together fast installation, thermal storage and on-demand hot water in one outdoor system.

PHNIX will continue to develop integrated heat pump solutions that make residential projects easier to plan and deliver.
