01.07.2025 - Monoblock heat pumps with R290
Expanded heat pump range
Press InformationThe heat pump market has undergone significant change. While demand was evenly split between split and monoblock units in recent years, monoblock units have been gaining ground in the market in recent times. Mitsubishi Electric's expanded range of monoblock heat pumps reflects this development. With a wide range of units, a comprehensive training program, and numerous services, we offer specialist tradespeople the best possible support. This enables our specialist partners to successfully compete and impress customers with optimal and efficient solutions.
Good to know: Mitsubishi Electric is a renowned heat pump brand and one of the pioneers of inverter technology. As a developer and manufacturer of refrigerant compressors - the heart of every heat pump - we pass on our in-depth knowledge to our specialist companies in a variety of formats.

Wide selection for every requirement
Wide selectionFive performance indicators for new and existing buildings
With the expansion of the PUZ-WZ series, we now offer a total of five output sizes (5, 6, 8.5, 10, and 12 kW) of our Ecodan air-to-water heat pump in a monoblock design, which can be used to implement tailor-made and future-proof heating solutions in both new and existing buildings.
Based on the natural refrigerant R290 (propane), Ecodan monoblock heat pumps with flow temperatures up to 75 °C and domestic hot water up to 70 °C are designed for small existing buildings.

The range of outputs allows us to cover different modulation ranges and offer specialist tradesmen and planners a better choice of equipment for every situation and requirement. In most cases, the output of the Ecodan heat pump can be precisely tailored to the determined demand.
Even more sustainable
Propane (R290)– thanks to propane (R290)
Our current 2025/2026 heat pump range and the recently published product information sheet "Monoblock heat pumps with natural refrigerant R290" contain a wealth of information about propane (R290). This natural refrigerant is used in many monoblock versions of Ecodan heat pumps, contributing to the sustainability and future-proofing of these devices. With flow temperatures of up to 75 °C, Ecodan monoblock heat pumps based on R290 are the ideal solution for existing buildings. They confidently and efficiently meet high peak loads for heating and domestic hot water requirements.
As a cascade system, the Ecodan monoblock heat pump with R290 refrigerant is also an ideal solution for larger buildings with higher heating requirements. Up to six outdoor units plus corresponding hydromodules as indoor units can be easily connected together to combine their output. The cascade connection with its MAX COP function from Mitsubishi Electric ensures that each individual heat pump always operates at its optimum output.
Comprehensive training
Training & Serviceand versatile service
In addition to efficient devices, a wide range of products, and in-depth technological expertise, we offer our specialist partners a comprehensive training program. Among other things, we provide basic knowledge on the use of R290 (propane) in air/water and air/air applications. It is also possible to obtain a refrigerant certificate that allows the handling of flammable refrigerants in accordance with DIN EN 378 and ISO 22712, which also includes R290.
Comprehensive on-site support from technical advisors in the field (TBA) rounds out our range of services. We offer additional support via our technical hotline at +49 2102 1244-655 or by email at service.ecodan@meg.mee.com.
This comprehensive support reflects our many years of experience and focus on the heat pump sector. Thanks to this focus, which is also a unique selling point in the industry, we are able to offer suitable solutions for current market requirements and for almost every area of application as a technology leader for refrigerant compressors.
Mitsubishi Electric's comprehensive training program also offers specialist partners training courses on the use of the refrigerant R290 in air-to-water and air-to-air heat pumps.
