Why choose Avenir Renovations?
How to ensure efficient and economical hot water production?
An old or undersized water heater can quickly become a source of discomfort, excessive expenses, and repeated breakdowns.
An energy-consuming and underperforming device
Old water heaters, especially electric ones with traditional resistance, have low efficiency, poor temperature maintenance, and significant heat loss. This generates excessive consumption and skyrocketing bills, especially in homes occupied year-round.
These models consume a lot of electricity, sometimes require a long heating time, and can be noisy or bulky. Replacing them allows for an immediate gain in performance and peace of mind.
A capacity poorly suited to needs
A large family with a small tank or a studio with an oversized water heater... Poor sizing of the water heater is common and can lead to either outages or energy wastage.
Choosing the right capacity optimizes comfort without overconsumption. A well-sized installation heats up faster, avoids repeated breakdowns, and improves hot water management on a daily basis.
Frequent breakdowns or lack of maintenance
A device that leaks, no longer heats, or shows limescale deposits is often at the end of its life or poorly maintained. A water heater breakdown can quickly become a hassle in everyday life.
After ten years of use, it often makes more sense to replace the device rather than multiply repairs, especially if maintenance has not been regular.

FAQ – renovation or replacement of water heaters
How do I know if my water heater needs to be replaced?
Several signs may indicate that it's time to change your water heater:
- Water takes a long time to heat
- Noises or bubbles in the tank
- Signs of rust or moisture
- Increase in electricity consumption
If your device is over 10 years old, or if you notice a drop in pressure or temperature, a replacement is often more cost-effective than a one-time repair.
What capacity should I choose for a water heater?
This depends on the number of people in the household:
- 50 to 100 L for 1 to 2 people
- 150 to 200 L for a family of 3 to 4 people
- 250 L and more for a household of 5 or more
You should also consider the sanitary equipment present, such as a bathtub or a multi-jet shower, which influence consumption.
Is a thermodynamic water heater really cost-effective?
Yes, even though the initial investment is higher, it is quickly offset by the savings made:
- Consumption reduced by 2 to 3 times compared to an electric water heater
- Longer lifespan
- Limited maintenance
Moreover, energy grants help reduce the purchase cost, further improving its long-term profitability.
