Shopping guide
Energy consumption
One of the most important characteristics that you must take into account is the consumption generated by the device, so that you can average the extra energy expenditure and thus know if you will be able to pay the electricity bill.
Regarding this point, it is highly recommended that the boiler that you are going to acquire be modulating, which facilitates starting when working with very low powers, thus significantly reducing the number of switching on and off that the device undergoes, resulting in greater savings in electricity consumption. The modulation range is expressed in different levels, being 1:10 the value that represents the highest work efficiency.
On the other hand, the modulating thermostats that are usually integrated into the boiler take into account the outside temperature and help regulate the temperature of the boiler, thus adjusting it more precisely to your desired level of heat. Thanks to this, the thermostat also affects the degree of energy saving.
On the other hand, it allows the boiler to work consuming the least amount of energy possible to achieve the greatest comfort for the user, making maximum use of the features offered by the boiler.
Power
In any guide to buying a boiler, you will find that power is one of the most important characteristics that you must take into account when choosing your model, since it directly affects the power and performance of the electrical device, as well as the level of consumption. it generates, so as the power increases, the electricity bill increases considerably.
These systems guarantee greater comfort in unfavorable situations, such as when another tap is opened while you are taking a shower or if the water is very cold in winter. It should also be considered that at higher power, the boiler is capable of generating a greater flow of water.
Before choosing the boiler model that you like the most, it is advisable to calculate the measurements of your house, so that you can know the indicated power for those dimensions. In other words, you must choose a suitable boiler for the size of your home, so that there is no energy waste.
It must be taken into account that when the power is positioned above the needs, the house will overheat, so more energy will be consumed. For a domestic installation, the power usually varies between 12 and 70 kW, depending on the exact square meters. For this reason, if you are wondering how much a boiler costs, it is important to know the power.
Control
Another of the most important features that you should take into account when choosing your new boiler is its ease of control. These devices usually have a control panel that is easy to access and simple and intuitive to use for all users, with which you can program the basic functions and adjust the desired temperature for heating and hot water. Control panels usually incorporate an LCD or LED screen that helps to know the program and temperature selected by the user.

Frequent questions
Q1: Why does the boiler leak?
Normally, when a boiler loses water it is due to a problem with the internal pressure of the device, so you must relieve the pressure using the safety valve that these devices traditionally incorporate. Logically, an optimal installation of the internal components that allows reaching high pressures is very necessary to minimize the risk of valve misadjustment.
If the boiler starts to release water, mainly check its nanometer, where the needle should mark between 1.5 and 5 kg per square centimeter, which is the recommended pressure that a well-functioning boiler should have. If the pressure gauge indicates a higher value than recommended, you will have to empty the bath. To check if the pressure drops, with a small emptying, one of the two radiators must be purged.
Q2: Which boiler is better, Junkers or Saunier Duval?
When we talk about the Junkers or Sauriel Duval brand, we are talking about two leading brands in the manufacture of high-quality boilers, offering great features and very reliable products, which are oriented so that the user achieves the greatest comfort at home. Both brands focus on the manufacture of condensing boilers with large modulation ranges, with the aim of obtaining greater performance using lower consumption, as well as offering maximum performance.
In the same way, they manufacture boilers that adapt to the temperatures required by the user. In this sense, the Junkers boilers differ from the Sauriel Duval models by being more compact and quiet, which require easier maintenance. On the other hand, the Sauriel Duval models stand out for their ease of use, being very intuitive and with a complete control panel for each function.
Q3: When should the gas boiler be checked?
It is very important and mandatory to carry out a review of domestic gas boilers, especially if they work with a power of less than 70 kW, with which you can verify the energy efficiency of the boiler, as well as check that the gas emissions are correct..
These reviews are of vital importance for the correct operation of gas boilers, which is why the regulations for thermal installations in buildings indicate that users must review them every two years and, in the case of water heaters, it must be carried out every five years.
Q4: What to do when a boiler loses pressure?
First of all, it is important to know that if your boiler suffers a fault due to low pressure, it is normal for the appliance to make a noise every time the water passes through the circuits. In this way you will know that you must pay attention to the pressure, which, if it drops below 0.5 bar, will stop the operation of the boiler, so as to avoid damaging the system.
To increase the pressure of the boiler again, it is necessary, first of all, to slowly open the heating filler valve in a counterclockwise direction. When the pressure reaches a range between 1 and 1.5 bar, proceed to close the filling valve. Finally, check again that the boiler is working properly.
Q5: What interests me, boiler or stove?
Mainly, it is important to know your personal needs and the use that you are going to give the device, so that you can choose between a boiler or a stove, keeping in mind that they do not offer the same operation. The boilers work to heat hot water while serving as a heater and come in gasoline, gas or electric models, allowing them to be installed in your kitchen cabinets thanks to their compact size.
