Energy Savings: Why Choose A Condensing Boiler?

You have finally made the decision to change your old boiler. However, choosing a new technology is not an easy decision. You still have doubts about choosing condensing technology. So without further ado, let’s dive into this blog and learn some of the reasons why you should choose a condensing boiler.

How does a condensing boiler work?


A condensing gas boiler provides heating and hot water production in your home. To operate, it burns gas which produces heat. The innovation of the gas boiler is that it uses the water vapor contained in the smoke:

  • At the heart of the device, combustion is created and produces heat.
  • This heat is transmitted via a heat transfer fluid to your heat emitters (radiators, underfloor heating, etc.) and to your water points.
  • The combustion fumes are recovered from being transformed into water vapor.
  • This steam increases the temperature of the heat transfer fluid.
  • A connection evacuates the water resulting from the condensation to the waste water drain.

To save money

The condensing boiler has an efficient system and control technology. It is equipped with two sensors: an indoor sensor and an outdoor sensor. The outdoor sensor measures the temperature outside your home, while the indoor sensor measures the temperature inside. The temperature rise of the boiler is then regulated by taking into account the data provided by these two sensors. The objective of this system is to provide heating at a perfect temperature. This is why the condensing boiler does not provide too high or too low temperatures. It is always normal and focused on the optimum thermal comfort of the house. This device avoids energy losses and allows you to save money. To choose a model that suits your needs, it is recommended to ask for advice from an air conditioning professional. This company specializes in installing, maintaining, and repairing air conditioning systems.

For better performance

The operating principle of the condensing boiler is the same as that of the conventional boiler, with one exception. The slow heat produced by the water vapors in the flue gases in the condensing boiler is entirely recovered. This results in a 100% higher efficiency than a conventional boiler (91% efficiency). In reality, condensation corrects the boiler’s performance by 15 to 20%.

Thermal comfort is another invaluable benefit that results from the condensation process. Besides the better performance of your boiler, the appliance will adapt to your needs according to your habits. Most condensing boilers are designed with two-in-one systems. Your comfort will then be improved as regards the production of hot water and heating.

With respect to the environment

If you want to combine economy and ecology, choose renewable energy boilers. The boiler limits the loss of energy thanks to the reuse of the water vapors from the flue gases. As a result, it releases very few particles into the atmosphere.

For a better return on investment

As a general rule, condensing boilers are much more expensive than conventional boilers. While an entry-level conventional boiler costs 2500 dollars, the condensing model will cost 3,000 dollars. It is clear that condensing technology is much more expensive. However, energy saving is your major asset. It will allow you to make your investment profitable between 3 and 5 years, depending on the boiler model.

To take advantage of many financial benefits

The purchase of a gas-condensing boiler allows you to benefit from certain financial advantages. Since 2020, it has replaced the “Energy Transition Tax Credit”. The amount granted under this aid is variable. It is:

  • 800 dollars for households with modest incomes
  • 1200 dollars for households with very modest incomes.

The aid is granted directly at the end of the work. You don’t have to wait a year to receive it. In case you do several renovation works, you will have to choose a different program.
