Availability: InStock

The Midea M-Thermal Nature R290 MHC-V12WD2RN7-BER90 is the first of the four models with a 9 kW, three-stage heating element, fed from the same three-phase supply; the V10 heater needs its own single-phase supply. Heating output is 12.10 kW (A7W35), 12.30 kW (A7W45) and 11.90 kW (A7W55), with a COP of 4.95, 3.90 and 3.25. It suits a site where the 9.50 kW of the V10 is no longer enough, but a COP of 4.95 and 55 dB(A) matter more than the extra kilowatts of the V14 and V16. Cooling is 11.50 kW (A35W7) and 12.00 kW (A35W18), the refrigerant is R290 (1.5 kg), heating-circuit water reaches 80 °C and domestic hot water 70 °C.

How the V12 differs from the V10 and V14

The closest models in this range are Midea MHC-V10WD2RN7-BE30 and Midea MHC-V14WD2RN7-BER90. The table shows the parameters on which they genuinely differ.

Parameter	V10	V12	V14
Heating capacity (A7W35)	9.50 kW	12.10 kW	14.00 kW
Heating capacity (A7W55)	9.50 kW	11.90 kW	13.80 kW
COP (A7W35)	4.95	4.95	4.70
Cooling capacity (A35W18)	10.00 kW	12.00 kW	14.00 kW
Sound power level	54 dB(A)	55 dB(A)	57 dB(A)
Heating element	3 kW, 1 stage, separate single-phase 220–240 V supply	9 kW, 3 stages, same three-phase supply	9 kW, 3 stages, same three-phase supply

Choose the V12 when 9.50 kW is no longer enough but a COP of 4.95 and 55 dB(A) matter more than extra kilowatts. If 9.50 kW is enough, the V10 is quieter (54 dB(A)) and has the higher SCOP (5.33 against 4.94 at 35 °C); if 12.10 kW falls short, the V14 gives 14.00 kW at A7W35, with a COP of 4.70 and 57 dB(A).

What is the MHC-V12WD2RN7-BER90 monobloc air to water heat pump used for?

The Midea MHC-V12WD2RN7-BER90 handles space heating, cooling and domestic hot water: the heating circuit water temperature is adjustable from 25 to 80 °C and hot water from 20 to 70 °C. The cooling modes A35W7 and A35W18 give 11.50 kW and 12.00 kW respectively. As a monobloc, the whole refrigerant circuit sits in one unit (1051×1330×475 mm), which connects to the system with 5/4" water pipes.

How cold can this Midea heat pump run in winter?

In heating mode the V12 operates at outdoor temperatures down to −25 °C. Ice build-up is limited by intelligent defrost and base-pan heating. The sound power level is 55 dB(A), and the model is Quiet Mark certified.

How much less electricity does it use than direct electric heating?

The seasonal efficiency SCOP is 4.94 at 35 °C and 3.96 at 55 °C. From a SCOP of 4.94, the unit uses roughly 80% less electricity than direct electric heating for the same amount of heat. This is a calculation, not a figure stated by the manufacturer.

Power supply and connections

The main unit runs on a three-phase 380–415 V / 3 / 50 Hz supply, and the built-in 9 kW heating element (3 stages) uses the same three-phase supply.

5/4" water connections, water flow 0.70–2.50 m³/h.

Frequently asked questions

What are the heating output and COP of the V12 heat pump?

At A7W35 the Midea MHC-V12WD2RN7-BER90 delivers 12.10 kW with a COP of 4.95. At A7W45 the output is 12.30 kW with a COP of 3.90, and at A7W55 it is 11.90 kW with a COP of 3.25.

Can the MHC-V12WD2RN7-BER90 also cool?

Yes. The Midea MHC-V12WD2RN7-BER90 cools at 11.50 kW in A35W7 mode (EER 3.05) and 12.00 kW in A35W18 mode (EER 4.60).

What outdoor temperature can the V12 heat pump work down to?

In heating mode the Midea MHC-V12WD2RN7-BER90 operates down to −25 °C outdoors. Ice build-up is limited by intelligent defrost and base-pan heating.

What water temperature does the MHC-V12WD2RN7-BER90 reach?

The Midea MHC-V12WD2RN7-BER90 heats water in the heating circuit up to 80 °C, and domestic hot water up to 70 °C.

How noisy is the V12 heat pump?

The sound power level of the Midea MHC-V12WD2RN7-BER90 is 55 dB(A), and the model is Quiet Mark certified.

What power supply does the V12 heat pump need?

The main unit of the Midea MHC-V12WD2RN7-BER90 runs on a three-phase 380–415 V / 3 / 50 Hz supply. The 9 kW heating element (3 stages) uses the same three-phase supply.

Which refrigerant does the MHC-V12WD2RN7-BER90 use, and is it safe?

The Midea MHC-V12WD2RN7-BER90 uses the natural refrigerant R290 (propane), 1.5 kg in total. Separate flammability safety requirements apply to units like this, so Hybrid Energy agrees the installation location with you in advance.

How much electricity will the V12 heat pump save?

From a SCOP of 4.94 at 35 °C, the Midea MHC-V12WD2RN7-BER90 uses roughly 80% less electricity than direct electric heating for the same amount of heat. At 55 °C the SCOP is 3.96, so the saving is smaller.

How is the MHC-V12WD2RN7-BER90 controlled, and can units be cascaded?

The Midea MHC-V12WD2RN7-BER90 is controlled with a wired controller or a mobile app and supports Modbus RTU and Smart Grid. Up to 6 units can be connected in a cascade.
