The Midea MHC-V4W (MHC-V4W/D2N8-B2E30) is the quietest air to water monobloc in the M-Thermal PRO R32 Monobloc series, with a sound power level of 55 dB(A). It is a single-phase unit with a heating output of 4.20 kW at A7W35 (COP 5.10), and it is reversible: it heats, cools (4.70 kW at A35W7) and prepares domestic hot water. It suits buildings with low heat loss where quiet running matters; if you need more output, look at the 6 kW or 8 kW model.

How the Midea MHC-V4W differs from the MHC-V6W
| Parameter | MHC-V4W | MHC-V6W |
|---|---|---|
| Heating output A7W35 / COP | 4.20 kW / 5.10 | 6.35 kW / 4.95 |
| Cooling output A35W7 / EER | 4.70 kW / 3.45 | 7.00 kW / 3.00 |
| SCOP (35 °C / 55 °C) | 4.85 / 3.31 | 4.95 / 3.52 |
| Sound pressure level at 1 m | 45.00 dB(A) | 47.50 dB(A) |
| Water flow range | 0.40–0.90 m³/h | 0.40–1.25 m³/h |
| Annual electricity consumption (35 °C, manufacturer’s calculation) | 2351 kWh | 2845 kWh |
Choose the MHC-V4W when the building’s heat loss is low and quiet running matters most: its sound power level of 55 dB(A) is the lowest in the series (the other models are 58–68 dB(A)). If you need more heat, take the MHC-V6W, which delivers 6.35 kW at A7W35 and a flow of up to 1.25 m³/h. Both are single-phase and share the same compact cabinet (1299×717×426 mm, 90 kg).
What is a 4 kW Midea air to water monobloc heat pump used for?
The Midea MHC-V4W suits sites with a low heat demand: its heating output is 4.20 kW (A7W35), 4.30 kW (A7W45) and 4.40 kW (A7W55), with a water flow of 0.40–0.90 m³/h. The sound pressure level at 1 m is 45.00 dB(A), which is worth considering if the outdoor unit will stand near bedroom windows. All hydraulic components sit in the outdoor unit, so only a water pipe enters the building.
- Heating at outdoor temperatures from −25 to 35 °C
- Cooling at A35W7 up to 4.70 kW
- Domestic hot water at 20–60 °C
- Integration via Modbus RTU and Smart Grid, cascade of up to 6 units
What water temperature and COP can a monobloc heat pump reach for underfloor or radiator heating?
The Midea MHC-V4W supplies heating water at 25–65 °C, and efficiency depends on the temperature you choose: the COP is 5.10 at 35 °C (A7W35), 3.80 at 45 °C and 2.95 at 55 °C. Underfloor heating and low-temperature radiators are therefore where the heat pump runs most economically.
The seasonal SCOP is 4.85 at 35 °C and 3.31 at 55 °C, and the seasonal efficiency ηs is 191.0 % / 129.5 %. By the manufacturer’s calculation (average climate), annual electricity consumption is 2351 kWh at 35 °C and 2744 kWh at 55 °C.
Heat pump installation: what to know about R32 and a certified installer
The Midea MHC-V4W uses R32 refrigerant (1.40 kg, CO₂ equivalent 945.0 kg), a fluorinated greenhouse gas. The EU regulation requires people working with such equipment to be certified (translated from the Lithuanian version of the text):
“Natural persons carrying out the activities referred to in points (a), (b) and (c) of the first subparagraph of Article 10(1) shall be certified in accordance with Article 10.”
In practice, you cannot install and commission a heat pump yourself: installation, charging and servicing are done by a certified specialist, and the work is recorded.
We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it.

Frequently asked questions
What heating output does the Midea MHC-V4W have?
At A7W35 the Midea MHC-V4W delivers 4.20 kW with a COP of 5.10. At A7W45 the output is 4.30 kW, and at A7W55 it is 4.40 kW.
What are the COP and SCOP of the Midea MHC-V4W?
The COP of the Midea MHC-V4W at A7W35 is 5.10, and the seasonal SCOP is 4.85 at 35 °C and 3.31 at 55 °C leaving water. The manufacturer states efficiency class A+++ (35 °C) / A++ (55 °C).
Is the Midea MHC-V4W suitable for radiator heating?
Yes, the Midea MHC-V4W supplies heating water up to 65 °C, and the COP at A7W55 is 2.95. The lower the water temperature, the higher the COP: it is 5.10 at 35 °C, so underfloor heating suits it especially well.
Does the Midea MHC-V4W heat when it is −25 °C outside?
Yes, the manufacturer states that the Midea MHC-V4W operates in heating mode at outdoor temperatures from −25 °C to 35 °C. In domestic hot water mode the range is −25 to 43 °C.
Can the Midea MHC-V4W cool a house?
Yes, the Midea MHC-V4W is reversible: at A35W7 the cooling capacity is 4.70 kW (EER 3.45) and at A35W18 it is 4.50 kW (EER 5.50). Cooling mode works at outdoor temperatures from −5 to 43 °C.
How noisy is the Midea MHC-V4W?
The sound power level of the Midea MHC-V4W according to EN 12102-1 is 55 dB(A), and the sound pressure level at 1 m at A7W35 is 45.00 dB(A). It is worth placing the outdoor unit away from bedroom windows and the neighbour’s plot.
What power supply does the Midea MHC-V4W need?
The Midea MHC-V4W needs a single-phase 220–240 V / 1 / 50 Hz supply, with a minimum circuit ampacity (MCA) of 25 A. The built-in heating element is 3 kW / 1 stage.
Can several Midea MHC-V4W units be cascaded?
Yes, the manufacturer states that up to 6 heat pumps can be connected in a cascade. The Midea MHC-V4W also has Modbus RTU and Smart Grid, so it can be integrated into a building management system.
Can I install the Midea MHC-V4W myself?
No, the Midea MHC-V4W uses R32 refrigerant (1.40 kg), so only a certified specialist may install and commission it. Hybrid Energy does it for you: we deliver anywhere in Lithuania, install and connect it.
Does Hybrid Energy help choose the right heat pump size?
Yes, Hybrid Energy sizes the heat pump by your building’s heat loss, not by floor area. The series has 7 models from 4 to 16 kW, and the Midea MHC-V4W delivers 4.20 kW at A7W35. A consultation before purchase is free.
