How the Midea M-Thermal-8B1HB2 differs from the M-Thermal-6B1HB2
The Midea M-Thermal-8B1HB2 differs from the 6 kW model in capacity (8.30 kW against 6.20 kW at A7W35), the larger hydraulic module HB-A100/CDS90GN8-B2 and a bigger outdoor unit: 75.0 kg net instead of 58.0 kg.
| Parameter | M-Thermal-8B1HB2 | M-Thermal-6B1HB2 |
|---|---|---|
| Heating capacity A7W35 | 8.30 kW | 6.20 kW |
| SCOP at 35 °C | 5.22 | 4.95 |
| Hydraulic module | HB-A100/CDS90GN8-B2 | HB-A60/CD30GN8-B2 |
| Outdoor unit weight (net) | 75.0 kg | 58.0 kg |
| R32 charge | 1.65 kg | 1.5 kg |
| Rated water flow | 0.40–2.10 m³/h | 0.40–1.25 m³/h |
Choose the 8 kW model if the house’s heat losses are higher than the 6 kW model covers: at A7W55 it delivers 7.50 kW against 6.00 kW. If 6.20 kW is enough, look at the Midea M-Thermal-6B1HB2: its outdoor unit is lighter (58.0 kg), it holds 1.5 kg of R32 and its indoor unit has a sound power level of 38 dB(A) against 42 dB(A). We size the capacity by the building’s heat losses, not by floor area.
Which house suits an 8 kW air-to-water heat pump?
The Midea M-Thermal-8B1HB2 has a heating capacity of 8.30 kW at A7W35 and suits a standard-sized family house with higher heat losses than the 4–6 kW models are meant to cover. Choose the capacity by the building’s heat losses, not by floor area, so talk to us before you buy: the consultation is free.
8 kW air-to-water heat pump for radiators and underfloor heating
The lower the flow temperature, the more efficiently a heat pump runs: the M-Thermal-8B1HB2 reaches COP 5.20 at 35 °C, 3.95 at 45 °C and 3.18 at 55 °C. SCOP is 5.22 at 35 °C and falls to 3.36 at 55 °C.
- A7W35: 8.30 kW heat output, 1.60 kW input, COP 5.20.
- A7W45: 8.20 kW heat output, 2.08 kW input, COP 3.95.
- A7W55: 7.50 kW heat output, 2.36 kW input, COP 3.18.
At 55 °C this model’s heat output (7.50 kW) is lower than at 35 °C (8.30 kW) and COP drops from 5.20 to 3.18; if the house has high-temperature radiators, weigh up this difference before buying.
Midea split heat pump: what is in the kit and how it connects
The kit consists of the outdoor unit MHA-V8W/D2N8-B2 and the wall-mounted hydraulic module HB-A100/CDS90GN8-B2. Both units connect to a single-phase 220–240 V / 50 Hz supply. The units are linked by refrigerant piping (gas 5/8″, liquid 3/8″) up to 30 m long; the height difference between them can be up to 20 m, and no extra refrigerant is needed for pipe runs up to 15 m.
The hydraulic module houses the circulation pump, expansion vessel, sensors and safety devices. You can control the system with a wired controller or the mobile app; it supports Modbus RTU and cascade connection, and additional heat sources can be connected.
Can I install an air-to-water heat pump myself?
No. The Midea M-Thermal-8B1HB2 uses R32 (1.65 kg), a fluorinated greenhouse gas, so connecting, charging and servicing it must be done by a certified specialist. Regulation (EU) 2024/573 states (our translation of the Lithuanian 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.”
We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it.
