Rules for choosing a dual-circuit wall-mounted device
There are a huge number of different gas boilers on the market for heating apartments and country houses. Most of them are compact and lightweight devices, which do not take up much space in the kitchen or pantry.
Wall-mounted models are usually less power, than floor-standing ones. Double-circuit ones help not only to heat the house, but also heat the water.
When choosing a gas boiler, pay attention to:
- on heating capacity and area;
- for availability water heating functions;
- on warranty and free service period;
- on reliability of the material from which heat exchangers and burners are made;
- on economical energy consumption;
- on electric ignition;
- on ease of control system.
It is necessary to select the optimal option for removing exhaust gases through certain systems of a chimney, fan and various types of pipes.
Reference! The larger the area of the house, the more powerful the boiler should be. Keep in mind that for heating 10 square meters leaves in order 1 kW power. Accordingly, the boiler capacity less than 10 kW it is not economically feasible to buy.
If required constant maintenance of water temperature, it is advisable to give preference to boilers with a flame modulation function. It is better to choose heat exchangers made of stainless steel, as they last the longest.
They have proven themselves to be excellent cast iron and aluminum details. In order for the equipment to be used for many years, it must have a serious safety system: protection against overheating, voltage drops in the network, freezing.

New generation technology
The most expensive on the market are – condensing boilersThey are considered environmentally friendly and have a higher efficiency than convection models.
All combustion products in condensing boilers are cooled, thereby releasing energy that increases the efficiency of the boiler.
New generation technology always has liquid crystal display with the ability to indicate the error code in the boiler operation.
You will easily receive information about the malfunction and will be able to take the necessary measures. The cost of such elite equipment starts from 100 thousand rubles and reaches 300 thousand rubles and more.
Attention! The latest generation of programmable models are developed taking into account systems such as "Smart home". This means that they can be control via the internet using gadgetsIt is possible to heat the house before arrival using your phone or tablet.
The remote control or phone can be used to set the specific temperature conditions and when heating water for bathing. When the required mark on the thermometer is reached, the boiler stops working by itself, and resumes working by itself if the coolant cools down. Thanks to the electronic control system, the boiler controlled with virtually no human intervention, and you will always be able to maintain a comfortable and stable temperature in your home.
