Equipping an electric boiler in a modern home is a wise choice in order to ensure comfort. Now available in several designs, models and power systems, the choice of this device should not be made randomly, some criteria must be considered, but which criteria are we talking about exactly ?
The different electric boiler models
In just a few years, the technology of electric boilers has made steady progress. This concerns all aspects of this device such as its design and practicality. Therefore, the electric boiler should be able to occupy any specific a place of choice if you plan to replace your current boiler.
Note that the most popular electric boilers are wall mounted electric boilers. As the name suggests, it can easily hang on a wall in any room of your home, therefore, it does not take up much space.
Note that there are also boilers on the floor, more cumbersome (but not more powerful), and that these two types of electric boilers exist with or without integrated hot water tank (also called cumulus).
First, what is the boiler used for ? To generate heat for the hot water tank, radiators or floor heating . Generally, the power of this equipment should be around 9 to 12 kW for an area up to 100 m² (heating and domestic hot water). Beyond that, it is more efficient to turn to an electric boiler of 15 to 24 kW.
It is also important to take into account the outside temperature and the loss of energy due to insulation quality. It is possible that you are lost looking at all this various data, which is why the assistance of an expert in the matter is always better to ensure to make a good purchase.
Efficiency and power consumption: key criteria
The heating capacity of an electric boiler depends on its efficiency , which is the ratio between the energy consumed and the energy produced. In theory, the efficiency of an electric boiler can reach up to 100%, as there is no heat loss compared to combustion boilers (gas, wood …).
The electric boiler will allow you to avoid paying for fuel as opposed to wood boiler, gas or oil. However, you will see the cost on your electricity bill. Additionally, the progress made by the latest models of electric boilers allows you to achieve up to 15% electricity savings compared to traditional models.
