The current UK page calls this product M Thermal R32 Air Source Heat Pump, while the 2026 specification sheet identifies it as the R32 Monobloc. The refrigerant and hydraulic functions remain in the outdoor unit, with water pipework connecting it to the building.
Domestic and commercial code groups
The domestic single-phase codes are MHC-V4W/D2N8-B2, MHC-V6W/D2N8-B2, MHC-V8W/D2N8-B2, MHC-V10W/D2N8-B2, MHC-V12W/D2N8-B2, MHC-V14W/D2N8-B2 and MHC-V16W/D2N8-B2. Three-phase domestic forms are MHC-V12W/D2RN8-B2, MHC-V14W/D2RN8-B2 and MHC-V16W/D2RN8-B2.
The commercial codes are MHC-V18W/D2RN8, MHC-V22W/D2RN8, MHC-V26W/D2RN8 and MHC-V30W/D2RN8.
The output table uses -2°C outdoor air and 50°C water. Its figures differ from several capacity labels, so the full MHC code and test condition are needed when an output is used in system design. The commercial and domestic groups also have different sound declarations and supply requirements.
Seasonal and high-temperature figures
The UK sheet gives separate SCOP (seasonal coefficient of performance) results at 35°C and 50°C for both domestic and commercial groups. The Product Directory uses 35°C and 55°C and contains overlapping certificate rows for the domestic codes. A value must therefore retain its source, code and application temperature.
Temperature wording differs between the UK and global sources. UK material headlines hot water up to 65°C and continuous hot-water production at -20°C outdoors. The combined global R32 page instead gives a 25°C to 65°C heating-water range, a 40°C to 60°C domestic-hot-water range and a -25°C ambient minimum for heating and domestic hot water.
Sound pressure is measured at 1 m in front. It rises across the domestic and commercial code groups, and it is not the same quantity as declared sound power or the noise level calculated for a proposed location.
Product records and annual warranty extension
The current UK range and 2026 sheet included the R32 Monobloc family at 23 July 2026. Current MCS entries existed for the domestic wildcard codes and all four commercial codes. Certification and design data follow the exact row, including its phase, suffix and certificate generation.
Midea’s warranty extension is renewed through registered annual maintenance. The general route extends annually up to five years. Extension up to ten years requires a maintenance agreement with the original Mi Pro installer and that installer’s continuing service registration.
