Replacing a Heat Pump in Mougins: When Home Comfort Demands Real Expertise
Nestled among the hills above Cannes, Mougins is renowned for its charming stone villas, lush olive groves, and peaceful residential neighbourhoods. But the mild reputation of the French Riviera can be deceiving — winter nights in elevated areas like Mougins, Mouans-Sartoux, and the Val de Mougins regularly dip close to freezing. Reliable heating is not optional; it is essential.
That is exactly why our Prestige Air team was called in to carry out the complete replacement of a heat pump at a private residence in Mougins. The homeowner’s existing unit had been in service for over twelve years and was showing clear signs of decline — rising energy bills, longer heating cycles, and an inability to reach the set temperatures.
The Initial Diagnosis: Understanding Before Acting
It all started with a phone call. Our client had noticed a steady drop in heating performance over the previous winter season. Rooms that used to warm up in minutes now took much longer, and the electricity consumption had increased noticeably.
Our technician visited the property in Mougins to perform a thorough assessment of the heating system. The inspection revealed a significant loss of efficiency in the outdoor unit, along with ageing hydraulic connections that were no longer fully reliable. Rather than investing in costly repairs on equipment that had reached the end of its lifespan, we recommended a full replacement with a next-generation heat pump.
After conducting a thermal study of the property and discussing the homeowner’s heating needs in detail, we selected the Hitachi Yutaki M — a high-performance monobloc heat pump perfectly suited to homes of this size in the Mougins area.
Why the Hitachi Yutaki M? Performance Meets Reliability
The Hitachi Yutaki M heat pump we installed in Mougins was chosen for very specific reasons. Here are its key technical specifications:
- Nominal heating capacity: 16 kW (maximum 18 kW)
- Operating temperature: medium temperature up to 55°C
- Outdoor operating range: down to -25°C
- Seasonal energy efficiency (ETAS): 125% (in accordance with EU regulation No 813/2013)
- Power supply: three-phase
- Type: heating only (non-reversible)
This model is ideal for villas in Mougins and the Cannes hinterland that already have an existing hydraulic heating network. Its ability to operate efficiently even in very cold conditions makes it a dependable choice for the Riviera’s cooler hilltop winters, where overnight temperatures can drop below zero.
Step-by-Step: How We Carried Out the Installation in Mougins
1. Site Preparation and Removal of the Old Heat Pump
Before any work began, our team carefully protected the surrounding area — the terrace, garden plantings, and pathway access. The old heat pump was disconnected, drained, and removed in full compliance with environmental regulations, including the recovery of refrigerant gas by a certified technician.
2. Positioning and Installing the New Hitachi Monobloc Unit
The Yutaki M was placed in the exact location of the previous unit, which kept civil works to a minimum. Our technicians then completed the hydraulic connections to the existing heating network, checking pipe diameters for compatibility and pressure-testing every joint for perfect sealing.
3. Full Flushing of the Heating Circuit
This is a step that many installers overlook, but it is absolutely critical. We performed a complete flush of the entire hydraulic circuit to remove sludge, limescale, and debris that had built up in the pipework over the years. In Mougins, where the water is relatively hard, this flushing is even more important to protect the longevity of the new equipment and maintain optimal heat transfer.
4. Commissioning and System Configuration
Once all connections had been verified, our technician proceeded with the full commissioning of the Hitachi Yutaki M: checking system pressures, verifying flow rates, and programming the heating curve to match the specific characteristics of the property and the homeowner’s daily routine.
5. Smart Controls: Wifi Module and Remote Thermostat
To provide the ultimate in comfort and control, we installed two complementary devices:
- The Hitachi CSNET Home wifi module, which allows the heat pump to be controlled remotely from a smartphone — perfect for adjusting the heating before arriving home after a day out in Cannes or a weekend away.
- A Hitachi wireless radio thermostat with ambient temperature compensation, ensuring the indoor climate adjusts automatically and precisely throughout the day.
Both devices were configured on-site, and we provided a full hands-on demonstration to the homeowner so she could operate everything confidently from day one.
A Small Detail That Made a Big Difference
During our inspection of the existing heating circuit, our technician noticed that an isolation valve upstream of the buffer tank had a very slight weep — almost invisible to the eye, but detectable by touch. Left untreated, this kind of micro-leak can cause a gradual pressure drop and silent deterioration of the system over several months.
Even though this was not part of the original scope of work, our team replaced the faulty valve and secured the fitting on the spot. We simply informed the homeowner of what we had found and what we had done — at no additional cost.
That is how we work at Prestige Air. When we open a job, we close it properly. No loose ends, no shortcuts, no grey areas. It is this attention to detail that sets a genuine professional heat pump installation in Mougins apart from a basic equipment swap.
Warranties and Aftercare
The installation carried out by Prestige Air in Mougins comes with comprehensive warranty coverage:
- 3 years on parts

- 5 years on the compressor (subject to annual maintenance by a certified QualiPAC professional)
