Adjustment of your condensing boiler: save on your energy consumption in 2025.
The rising cost of energy makes it essential to optimize our consumption, particularly regarding heating. In France, gas boilers are the most common equipment for domestic heating. With the evolution of technologies, condensing boilers stand out for their energy efficiency, allowing savings on bills. What are the best practices for setting your condensing boiler in 2025? Let's take stock together.
The Different Types of Gas Boilers
There are several types of gas boilers, each offering unique features. The boilers commonly found in households include:
Conventional gas boiler: This is the traditional model, with an efficiency often limited to 80%. Although its price is attractive (500 to 2500 euros), its efficiency is undermined by its high consumption.
Low-temperature gas boiler: Operating around 50°C, it consumes about 30% less gas than the conventional one, achieving an efficiency of nearly 90%. Its cost ranges from 1500 to 5000 euros.
Condensing gas boiler: These boilers reuse the heat from the exhaust gases to reach an efficiency of up to 120%. Although they cost between 3500 and 7000 euros, the energy savings they generate make them a wise choice.
Pulsating gas boiler: Its efficiency can exceed 109%, with a reduced consumption of 25 to 40%. However, its high price (over 5000 euros) may hinder its adoption.
Micro-cogeneration boiler: This technology produces both heat and electricity, with an efficiency ranging from 105 to 110%. Purchase price between 12000 and 20000 euros.
The Optimal Setting of Your Condensing Boiler
To maximize the efficiency of your boiler, proper settings are crucial. Here are some factors to consider:
Effective Heating Temperature
The temperature of the water in the radiators is fundamental. Here are the recommendations:
Type of Radiator | Recommended Temperature (°C) |
|---|---|
High temperature | 70-75 |
Medium temperature | 55-60 |
Low temperature | 35-45 |
Precise settings at the boiler level ensure lower energy consumption and increased comfort.
Sanitary Hot Water Mode
Setting the temperature of the sanitary hot water between 50 and 55°C is sufficient for daily use while limiting energy consumption.
Programming and Regulation
Use a programmable thermostat to adjust the temperature according to your needs. Here are some tips:
Set to 19-20°C during your presence at home.
Lower to 16°C during your absences or overnight.
Additionally, if your system allows it, an outdoor sensor can adjust the water temperature according to outdoor levels, thus optimizing efficiency.
Maintenance and Management
Regular maintenance is essential to extend the lifespan of your boiler. Here are the practices to adopt:
Have your boiler serviced once a year by a professional.
Bleed your radiators to eliminate trapped air, which hinders their efficiency.
In case of prolonged absence, set your boiler to frost protection mode.
A well-executed setting ensures optimal thermal comfort while reducing your energy bills.
