Types of Hot Water Boiler Systems

How It Works

Types of Hot Water Boiler Systems

There are four major types of hot water boiler systems available which are mentioned below:

1. Closed System: In these types of systems, the water which gets evaporated and converted into steam is again put back into use by condensing the steam back to liquid form. This means that the 100 percent reutilization of the water takes place in closed systems.
2. Open System: In these systems, the water is heated up but the evaporated water is not put back for reutilization inside the system.
3. Single-pipe System: In these systems, two pipes are utilized. One pipe is used for carrying the heated water to the required location whereas the second pipe is used for returning the cool water back towards the boiler by means of a motorized pump.
4. Gravity System: These are the older hot water boiling systems in which the water is carried back after heating via the gravity effect. Hence, in these systems, circulators are not required.

Main Features

Following are the significant features associated with the use of hot water boiler systems:

• Although the installation of hot water boiler systems is extremely costly yet they are frequently employed for heating applications owing to their high efficiency and cost in comparison to forced-air boiler systems.
• Since the hot water boiler systems are made up of aluminum fins and copper pipes, they tend to employ less metal for their construction and hence occupy comparatively smaller area.
• Hydronic boilers typically offer small and uniform values of temperature as compared to forced-air boilers. Moreover, in these systems, the on-off switching action is usually prevented because of the ability of baseboard pipes to grasp the heat and liberate it over longer periods of time.
• Another important feature regarding hot water boilers is that they dry the air inside the system to a very small extent only.
• A Hydronic boiler does not allot allergens, dust, combustions or mold by any products that enter living space. This is always an advantage, especially for a family that is sensitive with allergies.
• The piping mechanism within a hot water boiler system is very exceptional and its correct implementation is very much responsible for the proper operation of the boiler.
• A single hydronic boiler system per home is usually found adequate to produce necessary heating effect, unless it’s a big triple story house.
• Hot water boilers are mainly employed for domestic heating applications, generally in the northern parts of Europe.
• Hydronic boiler systems are mainly applied as central heating system inside buildings to give heating effect to the areas, which are otherwise very cold.
• A typical hot water boiler operates throughout the winter with a water temperature determined by the Aquastat, or low limit, setting (an Aquastat is like a thermostat that senses the water temperature inside the boiler and shuts off the burner when the water is hot enough).
