Types of boilers and heaters
We offer this article to dispel the doubts of those who consider changing the boiler for heating in their home or workplace, both to update the installation by putting a new one as to put it for the first time. You can see and understand the operation of each system in the infographic attached to this publication. The heating boilers are hot water generators in a closed circuit. This circuit is responsible for carrying the hot water to the radiators. The radiators dissipate the heat that comes to them, heating the room. The water once cooled returns to the boiler where it is heated again and so on.
Whether you are boilers to natural gas, boilers propane gas and oil boilers there are two basic types of boilers: The atmospheric boiler and flue boilers. The difference exists in the design of the boiler in terms of the air input necessary for combustion and the exit of gases to the outside.
- Atmospheric boilers. They are the simplest and also the oldest operating. The boiler takes the air from the room to burn. It is not allowed to install them in bathrooms or bedroom rooms. The atmospheric boiler can also only be installed if it is guaranteed that the vertical draft of the smoke outlet is high enough so that the fumes leave easily, without being amused. Atmospheric boilers are influenced by atmospheric conditions: wind, rain.
- Sealed boilers. They are equipped with a concentric gas outlet pipe, which allows extracting the air from the outside and expelling the fumes through the same exhaust pipe. Thanks to this arrangement, the sealed boiler is much safer, allowing it to be installed in any room, even if it is a bedroom. For the evacuation of gases has an extractor that forces these to go outside! In watertight boilers, atmospheric conditions such as wind or rain, practically do not affect the correct operation. A mixed gas boiler is a heating system in our homes that in addition to using the gas energy source for a boiler and a water radiator installation to keep our home warm, it also provides sanitary hot water (DHW).
- The boiler burns gas and in this way heats the water circulating inside it and that, by means of a circulating pump, it reaches the radiators distributed throughout the house and, on another circuit, the hot water pipes. The boilers not only can supply a heating circuit, but they can also generate sanitary hot water (DHW), so they can also be classified into two types: simple boilers and mixed boilers:
- Simple boilers. They are the boilers that only feed a heating circuit. Although in its circuit accumulation tanks can also be mounted to obtain domestic hot water.
- Mixed boilers These are the boilers that are already prepared with two circuits, one for heating and the other for domestic hot water There are also two types of boilers that come to improve their operation in relation to the production of domestic hot water. They are boilers with micro accumulation and boilers with accumulation.
