Mitsubishi has expanded its Hydrolution EZY R290 heat pump series with two models with a capacity of 10 kW and 14 kW. The new products use refrigerant R290 and can deliver supply temperatures of up to 75 °C.
Mitsubishi Heavy Industries Air-Conditioning Europe, Ltd (MHIAE), part of Mitsubishi Heavy Industries, has expanded its Hydrolution EZY range with two new higher capacity products.
Available from June, the two new models offer capacities of 10 kW and 14 kW and are designed for large residential and small commercial applications. They both offer a single-phase 230 V supply or a newly added three-phase 400 V supply.
“Both new models are designed for quiet operation, with a double vibration isolation structure, three-layer sound insulation, a large fan and a low-noise operation mode that reduces operating noise, ensuring compliance with noise regulations in densely populated residential areas,” the company said in a statement.
“The 14 kW unit produces a nominal sound power of 63 dB(A), while a dedicated quiet mode further reduces noise levels to 57 dB(A), supporting compliance with local noise regulations and making them suitable for installation in noise-sensitive environments,” the report said.
The 10 kW and 14 kW models are equipped with special electronic expansion valves for both heating and cooling circuits. The units also feature a double vibration isolation system, three-layer acoustic insulation and an extra large fan.
The new heat pumps use propane (R290) as a coolant, just like the two 6 kW and 7.1 kW models in the series that Mitsubishi launched in October 2025. “Thanks to the thermodynamic properties of R290 and the use of redesigned components, the Hydrolution EZY models can reach supply temperatures up to 75 C, while maintaining reliable performance in ambient conditions from -25 C to 43 C,” the manufacturer said.
“As a single, self-contained monobloc unit, the installation requires only minimal plumbing and electrical connections. All refrigerant is contained entirely within the outdoor unit, eliminating the need for refrigerant connections to the indoor unit,” the manufacturer said. “Only two water pipes and an electrical connection are required, minimizing on-site work and reducing commissioning time. For greater safety, the units are equipped with a built-in refrigerant leak detection sensor.”
The Hydrolution EZY series was first launched by Mitsubishi in January 2025. The series provides heating, cooling and domestic hot water (DHW) from a single outdoor unit. It features a coefficient of performance (COP) ranging from 3.45 to 4.50 and a energy efficiency class (EER) from 2.85 to 3.80.
Mitsubishi said the range is suitable for both radiator-based heating systems and domestic hot water production, without the need for extensive system upgrades. Additional features such as quiet operation modes, smart control connectivity and built-in refrigerant safety systems reflect their focus on home comfort, regulatory compliance and ease of implementation in European markets transitioning to low-carbon heating solutions.
