Equipping a home is no longer just about making a shopping list room by room. Since the reform of the DPE and the transition to an electricity coefficient of 1.9 in primary energy as of January 1, 2026, the choice of each structural equipment (heating, hot water, cooking) commits the energy performance of the housing for several years. Comparing equipment categories from this perspective allows for clearer prioritization of expenses.
DPE Coefficient and Home Equipment: What Changes in Practice
Traditional layout guides offer checklists by room, never crossing these choices with energy constraints. However, the European directive 2024/1275 imposes a new logic: to aim for a home operating 100% without fossil energy (neither gas nor oil) starting January 1, 2027, relying on electricity, renewable energies, or an efficient heating network.
The conversion factor of electricity into primary energy, which has changed from 2.3 to 1.9, alters the game for homes heated electrically. A high-performance electric radiator or an optimized electric water heater now improves the DPE rating of the home without additional work. In other words, the choice of an energy-efficient electric appliance directly impacts the value of the property.
This context renders the approach of “buying the cheapest in each category” obsolete. The right reflex is to cross three criteria for each item: the immediate function, the displayed energy consumption, and compatibility with an all-electric or renewable energy home.
Comparison of Equipment Categories by Impact on Daily Life and DPE
Not all equipment carries the same weight in the budget or has the same impact on energy performance. The table below ranks the main categories according to their purchasing priority and their influence on the DPE rating of the home.
| Equipment Category | Purchase Priority | Impact on DPE | Key Selection Criteria |
|---|---|---|---|
| Heating (radiators, heat pump) | Immediate | Very high | Type of energy, power suited to the area |
| Hot water production | Immediate | High | Thermodynamic or low-consumption electric water heater |
| Cooking plates | Immediate | Moderate | Induction (all-electric) rather than gas |
| Refrigerator / freezer | Immediate | Moderate | Highest energy class available within budget |
| Washing machine | First week | Low to moderate | Low temperature program, capacity suited to the household |
| Bedding (mattress, box spring) | Immediate | None | Comfort, durability of materials |
| Lighting | Immediate | Low | LED, dimmers to reduce consumption |
| Living room furniture / storage | Deferrable | None | Verified dimensions, modularity |
The first four categories in the table account for almost all of the DPE impact. Investing more in these areas and postponing the purchase of decorative furniture yields better overall results, both in terms of thermal comfort and property valuation. Browsing equipment on Brico Déco Home allows for quick identification of ranges compatible with an all-electric approach.
Kitchen and Bathroom Layout: Key Trade-offs
The kitchen and bathroom are the two rooms where most high-impact equipment is found.
Kitchen: Induction and Energy-Efficient Appliances
Replacing gas cooktops with an induction cooktop eliminates a fossil fuel category from the home. Induction consumes less energy than traditional ceramic cooktops for the same cooking time, resulting in measurable savings on the annual bill.
For the refrigerator and dishwasher, energy class remains the most reliable criterion. However, capacity must match the actual size of the household: an oversized appliance consumes more at partial load.
Bathroom: The Water Heater as a Strategic Item
The water heater represents a significant portion of a home’s energy consumption. A thermodynamic water heater uses ambient air to heat water, reducing electrical consumption compared to a traditional tank. Its purchase cost is higher, but the savings on the bill compensate for the difference in a few years.
- Check the capacity in liters according to the number of occupants (avoid oversizing that maintains unnecessary hot water volume at temperature)
- Prefer a location in an unheated room (garage, laundry room) to increase thermodynamic efficiency
- Check compatibility with the existing electrical panel, as some models require a dedicated circuit
Bedroom and Living Room: Distinguishing Immediate Comfort from Deferrable Items
Bedding is one of the purchases to make before moving in. Mattresses and box springs determine sleep quality from the first night. However, the bed frame, bedside table, or decorative storage can wait several weeks without penalizing daily life.
For the living room, a sofa with dimensions verified down to the centimeter avoids the most common problem when moving in: the piece of furniture that doesn’t fit through the door or hallway. Measuring the width of each passage (entry, stairs, elevator) before ordering remains the most cost-effective precaution.
Lighting deserves special attention. Installing LED bulbs from day one costs little and significantly reduces the lighting category’s consumption compared to halogens still present in some homes.
- Plan for at least two light sources per living space (ceiling light and accent lamp) to modulate the ambiance
- Install dimmers on main circuits, which prolongs bulb lifespan and reduces consumption
- Postpone the purchase of decorative light fixtures for a few weeks after moving in, to identify areas that are truly under-lit
Home Equipment and Budget: Prioritizing by Phases
Buying everything at once often leads to choosing entry-level products in each category. Spreading purchases over two or three phases allows for concentrating the budget on high-impact equipment (heating, hot water, kitchen appliances) in the first phase, then completing with furniture and decoration later.
This phased approach has an additional advantage: after a few weeks of occupancy, real needs become clearer. A storage solution that seemed necessary on paper may turn out to be unnecessary, while an unanticipated need (laundry shelf, entry furniture) becomes obvious.
Equipping a home benefits from being treated as a structured project rather than a series of impulsive purchases. Cross-referencing DPE constraints with the hierarchy of daily needs provides a stronger framework than traditional checklists by room. Homes equipped from the start with high-performance all-electric systems benefit from a better energy rating, which impacts their resale value as well as the comfort of the occupants.
