Hydronic boilers are those engineering device that are used for generating heat especially for residential uses. In different parts of the world they are used for central heating systems fitted to houses and are commonly combined with domestic water heating.

How It Operates?
Heating water/fluid set on a preset temperature, actually helps the hydronic boiler to operate. Through radiators, baseboard heaters or floors, the fluid gets circulated throughout the house. Natural gas is preferred to heat the liquid in built-up areas because of the availability of the piped gas. However, gas, wood, fuel oil etc. are also used. With the help of a motorized pump, the fluid, which is in an enclosed form, is spread throughout. Nowadays, condensing boilers are mostly used in latest systems simply because of their excellent efficiency.

Features
Following are the features of Hydronic Boiler:

• Inspite of its expensive installation, these boilers are comparatively more economical and efficient than forced-air systems.
  
  
• For these boilers, less space & metal is needed for baseboard copper pipes and aluminum fins.
  
  
• As compared to forced-air systems, they provide uniform and less fluctuating temperatures. The constant on-off switching of furnace is avoided since, the baseboard pipes hold and release heat over a longer period of time. Here, maximum copper heating is done through conduction and radiation while its through forced convection in forced-air system.
  
  
• Hydronic boiler do not dry out the interior air as much.
  
  
• They do not allow dust, allergens, mold, or combustion by products to enter the living space.
