Micoe R290 Plus Series DC Inverter All-in-One Heat Pump for Heating, Cooling, and DHW（4kW-18kW）

1.Product Overview
Micoe R290 Plus Series is a new‑generation DC‑inverter monoblock heat pump for heating, cooling and domestic hot water (DHW). Unlike split‑type units requiring field refrigerant piping between indoor and outdoor sections, the monoblock design encloses the complete refrigeration circuit inside the outdoor unit and connects to buildings via water pipes. It simplifies installation, cuts commissioning time and eliminates on‑site refrigerant‑leak risks. Available in 10 models with single‑phase and three‑phase options, it delivers 4kW‑18kW heating capacity, ideal for homes, villas, apartments and light‑commercial projects.

2. R290 Eco‑Friendly Refrigerant | A+++ Top Energy Efficiency
R290 Plus employs R290 refrigerant with an ultra‑low GWP of 3. Boasting zero ozone‑depletion potential and superior thermodynamic performance for high efficiency, R290 ranks among the market’s most sustainable refrigerants. It complies with EU F‑Gas regulations and global green‑building standards, exempt from fluorinated‑gas restrictions in many territories.
The unit achieves the highest A+++ rating under EU ErP requirements. Its SCOP reaches 5.33 at 35°C water outlet under average climate conditions, and retains A+++ classification with SCOP up to 4.03 even at 55°C outlet temperature — benchmark performance within its product class.
For buyers, A+++ efficiency means lower end‑user operating expenses, better access to government subsidies and stronger bidding advantages for project tenders.

3. Max 80°C Water Outlet | Dual‑Temperature‑Zone Control
Standard heat pumps typically top out at 55‑60°C outlet temperature, while R290 Plus reaches up to 80°C. Compatible with traditional radiators as well as underfloor heating and fan coils, it enables seamless retrofits of existing buildings that demand high‑temperature hot water. Aligned with the EU Renovation Wave targeting 35 million building retrofits by 2030 as Europe phases out fossil‑fuel boilers, this unit serves as an optimal replacement for gas and oil‑fired boilers.
Dual‑zone temperature control sets independent temperatures for different heating circuits — e.g. 35°C for underfloor heating, 55°C for radiators — so each system operates at peak efficiency.
For B‑sector customers: the 80°C high‑temperature capability unlocks large retrofit markets beyond new constructions. One unit handles heating, cooling and DHW, streamlining system layout, reducing hardware count and lowering total installation costs.

4. Full DC Inverter | Stable Operation at ‑25°C
Instead of frequent full‑power start‑stop cycles, R290 Plus continuously adjusts compressor speed to match real‑time heating demand. This avoids energy waste, maintains precise temperature control and extends compressor service life.
Reliable performance down to ‑25°C ambient temperature fits Northern and Eastern European regions with frigid winters. The factory‑sealed monoblock refrigeration circuit prevents performance drop‑offs caused by on‑site refrigerant‑pipe work.

5. Floating Compressor Chamber | Ultra‑Quiet 35dB(A)
Featuring an independent floating compressor chamber and six‑point suspension damping system, R290 Plus physically isolates the compressor from airflow and cabinet vibration. Combined with multi‑layer sound‑absorbing materials and reinforced metal shielding, operating noise drops to 35dB(A) measured at 1‑meter distance — quieter than a library. Well‑suited for noise‑sensitive residences and hotels, it minimizes end‑user noise complaints and supports installation near bedrooms and residential zones.

6. Smart Control & OTA Updates
R290 Plus comes standard with a 5‑inch TFT touchscreen controller and built‑in WiFi. The mobile APP enables remote monitoring, temperature adjustment, timer configuration and real‑time energy‑consumption tracking.
