Choosing the complete equipment for a house involves balancing between items that do not all have the same impact on the energy bill or the same lifespan. The energy label reformed since 2021, the aids conditioned to decarbonization, and the rise of connected devices are changing the decision-making criteria. Comparing these items on measurable bases helps avoid poorly calibrated purchases.
Usage Cost and Lifespan: Comparative Table of Key Items
The purchase price of equipment represents only a fraction of the actual budget. The annual usage cost and average lifespan differentiate options much more effectively than a catalog price.

| Equipment Item | Average Lifespan | Weight in Energy Bill | Note |
|---|---|---|---|
| Heating (heat pump) | 15 to 20 years | High (primary item) | Eligible for MaPrimeRénov’ and CEE |
| Thermodynamic water heater | 10 to 15 years | Medium | Consumes significantly less than a traditional water heater |
| Kitchen appliances (refrigerator, dishwasher) | 10 to 12 years | Cumulative medium | New A-G label since 2021 |
| Double flow VMC | 15 to 20 years | Low in direct consumption | Indirect impact on heating (heat recovery) |
| Home automation and connected security | 5 to 8 years (software obsolescence) | Very low | Frequent replacement cost |
Heating remains the item that weighs the most on the overall budget of a home. Prioritizing its sizing before choosing the rest of the interior equipment helps avoid compensating for an underperforming system with additional expenses.
To establish the complete maisonpro.fr equipment for a house, cross-referencing the projected lifespan with the annual usage cost provides a more reliable indicator than just the purchase price.

New A-G Energy Label: What Changes for Equipment Selection
Since March 2021, the European Union has removed the A+, A++, and A+++ classes to return to a scale of A to G with more demanding criteria. A device rated C today may perform better than an old A+++. The reading of performance is simplified, but it traps buyers who compare using the old method.
This reform concerns refrigerators, washing machines, dishwashers, and televisions. It requires checking the label date before any second-hand or clearance purchase: a product labeled A+++ before 2021 does not have the same value as a product rated B on the new scale.
Practical Reading of the Label for Kitchen Equipment
On a refrigerator, the annual consumption in kWh is now prominently displayed. Comparing consumption in kWh rather than just the letter alone remains the most reliable method, because two devices rated D can show a significant consumption gap depending on their volume.
For a dishwasher or washing machine, the number of cycles per year used for the calculation is standardized. However, actual usage varies from one household to another. A household that runs its machine daily will have a more marked cost difference between two classes than a two-person household.
Decarbonization of Housing: Aids and Constraints that Guide Choice
The national low-carbon strategy encourages prioritizing less carbon-intensive equipment. The MaPrimeRénov’ aids and energy savings certificates (CEE) are now conditioned on the choice of equipment compatible with decarbonization goals. This gradually excludes oil boilers and directs towards heat pumps, thermodynamic water heaters, or pellet stoves.
This regulatory constraint has a concrete effect on the budget: the out-of-pocket cost of a heat pump after aids can drop well below the installation cost of a gas boiler, depending on household income and geographical area. Conversely, installing a non-eligible system means bearing the entire cost without subsidy.
- Air-water heat pump: eligible for MaPrimeRénov’ and CEE, suitable for most individual homes
- Thermodynamic water heater: reduced consumption compared to electric water heaters, eligible for aids under conditions
- Pellet stove: efficient heating supplement, eligible, but requires a compliant flue
- Oil boiler: excluded from aids since the latest revisions of the scheme, replacement encouraged
Connected Devices and Security: A Short Lifespan Item
Home automation equipment (connected thermostats, detectors, cameras, smart locks) has a shorter functional lifespan than the rest of the household equipment. Software obsolescence often occurs before hardware failure, requiring renewal of the device every five to eight years.
The gain in daily comfort is real: a connected thermostat allows adjusting heating room by room, and smoke or intrusion detectors enhance the security of the interior space. The trap lies in multiplying incompatible systems.
Interoperability: The Often Overlooked Criterion
Before investing in a security or energy management system, ensuring that devices communicate via an open protocol prevents becoming captive to a single manufacturer. A closed ecosystem costs more in the long run than a set of devices compatible with multiple platforms.
The budget allocated to connected equipment should remain minor compared to structural items (heating, insulation, ventilation). A high-performance thermostat will never compensate for a poorly sized heating installation.
The final arbitration rests on a simple data point: the cumulative annual usage cost over the lifespan of each item. Public aids already guide towards the least carbon-intensive equipment, and the new energy label facilitates comparison at the time of purchase. It remains to check compatibility between connected devices to avoid accumulating equipment that will become unusable before being amortized.
