LinkedGo 25 kW R290 Ground/Water-Source Heat Pump: Tested 54.35 dB to EN12102

LinkedGo introduces its 25 kW R290 Ground/Water-Source Heat Pump, a next-generation system that combines quiet operation, high efficiency, and eco-friendly design. Independent laboratory testing to the EN12102 acoustic standard confirmed a sound power level of just 54.35 dB, giving homeowners and installers a verifiable benchmark for low-noise performance.
 

Verified Quiet: What EN12102 Means
EN12102 is the European reference method for measuring the sound power level of heat pumps and refrigeration equipment. Unlike sound pressure readings, which vary with distance and surroundings, sound power is an absolute measure of the unit’s acoustic output.
Testing to EN12102 ensures that LinkedGo’s published 54.35 dB figure is accurate, repeatable, and directly comparable to other certified products.
For homeowners, that translates into peace of mind: the data reflects the machine itself, not the quirks of a particular installation.

DC Inverter Compressor for Precision and Savings
At the heart of the 25 kW model is a DC Inverter compressor. Instead of cycling on and off at a fixed speed, the compressor continuously adjusts its speed to match heating demand and evaporating pressure.
Energy efficiency – No wasteful start-stop spikes; power draw is always matched to the actual load.
Lower electricity bills – Modulation reduces overall consumption across the heating season.
Stable comfort – Fine control maintains indoor temperatures without noticeable fluctuations.
Reduced noise – Smooth speed changes eliminate the abrupt sounds common to conventional on/off systems.

This adaptive operation is a key reason the heat pump delivers both high seasonal performance factors and quiet performance.

Integrated Brine and Circulation Pumps

To streamline installation and optimize efficiency, LinkedGo integrates both the brine (source-side) DC water pump and the load-side DC circulation pump inside the unit.

Automatic speed control – Each pump modulates flow to match real-time heat-exchange needs, keeping the system perfectly balanced.

Simplified setup – With the pumps factory-installed, contractors save space, reduce piping complexity, and shorten commissioning time.

Lower maintenance – Fewer external components mean fewer potential leak points and easier servicing.

This all-in-one design is especially valuable for residential projects where mechanical-room space and installation time are at a premium.

Multi-Layer Acoustic Engineering

Low noise isn’t left to chance. The 25 kW R290 heat pump employs a comprehensive acoustic strategy:

Compressor insulation – A 30 mm flame-retardant felt layer plus a 2 mm PVC barrier surround the compressor to absorb and block airborne sound.

Pipe treatment – All refrigerant and water lines are wrapped in acoustic insulation to prevent vibration from traveling through the building.

Suspended chassis – The compressor assembly is mounted on a floating base supported by double-ended stud rubber feet, with acoustic cotton beneath to isolate vibration from the cabinet frame.

These measures ensure that the certified 54.35 dB sound power level is achieved not only in the test lab but also in real-world installations.

Eco-Friendly R290 Refrigerant

The system uses R290 (propane) refrigerant, with a Global Warming Potential (GWP) of only 3—a dramatic improvement over legacy refrigerants such as R410A (GWP ~2088) or R32 (GWP ~675).
Benefits include:
Full compliance with current and future EU F-Gas regulations.
Excellent thermodynamic properties for high efficiency even in cold climates.
Smaller required refrigerant charge, further reducing environmental impact.
By selecting R290, homeowners gain a solution that is both future-proof and environmentally responsible.
 

Reliable Heating and Domestic Hot Water

Engineered for medium to large homes or multi-family dwellings, the LinkedGo 25 kW R290 model provides:
Space heating and domestic hot water from a single compact unit.
Consistent performance across a wide range of ground or water-source conditions.
Smart control integration, allowing remote monitoring and energy management.
The combination of DC Inverter control, integrated pumps, and R290 refrigerant ensures excellent seasonal efficiency and long-term savings.

A Quiet Step Toward Sustainable Comfort
The LinkedGo 25 kW R290 Ground/Water-Source Heat Pump, with its independently verified 54.35 dB sound power rating, demonstrates how cutting-edge engineering can deliver low-noise, low-carbon heating without compromising comfort.

From the precision DC Inverter compressor to the integrated DC pumps and layered acoustic insulation, every detail serves a single purpose: to provide homeowners with reliable, eco-friendly heating and hot water—quietly and efficiently—for years to come.
