When purchasing a hot water heating system, you will discover that you have two distinct types to choose from. The first type is identified as “Forced or Hydronic” and the second type is referred to as “Gravity”. Most homes today incorporate the use of the “Forced or Hydronic” hot water heating system. Now, there are some homes that still have the traditional “Gravity” models, but these systems are being updated frequently due to the fact that they do not possess a water pump system and they often utilize piping that is relatively large and bulky. Additionally, these systems are generally viewed as inefficient as they are slow to produce hot water and only supply a limited amount.

If you have a hot water heating system that is referred to as “Forced or Hydronic”, you will find that the unit is heated through the means of gas. In some cases, oil is used to provide the heat to the unit. There are some homes that have incorporated the use of heating coils that are electric resistant. If coils are used so that the device can be powered by electricity, the burner that is used in traditional heating models is actually replaced by the coils. When it comes to the piping that is responsible for delivering heated water throughout the home, the hot water heating system that uses any of these power means is similar and often interchangeable.

The next component of the hot water heating system in the home is the boiler. The boiler is usually composed of steel. In rare cases, these components have been created with cast iron. It has been estimated that the steel boilers have a life of about two decades. The cast iron models have a life of about three decades. Unfortunately, cast iron is considered inefficient when it comes to heating water due to the fact that heat is held more than it is passed. Steel, on the other hand, not only holds heat but it transfers it easily. As an owner of a hot water heating system, it is essential to ensure that the boiler unit is in good working order on a regular basis as these components have been known to develop leaks and even corrode over time.

The next component to your hot water heating system is the expansion tank. This unit may be placed in an isolated location such as an attic or basement, or it may be placed immediately above the area where the boiler is located. The piping that is used to distribute hot water throughout the home is actually connected to the expansion tank. Typically, this component will incorporate compression technology to distribute hot water as required. As a result, when water is heated, the air within the unit attempts to compress it. This helps to increase the general flow rate and output of hot water.

The next components of the hot water heating system in your home are the controls to the boiler. These controls typically include the following:

* A Pressure Gauge

* A Relief Valve for Pressure

* A Pressure Reduction Valve

The gauge that is related to the pressure indicates exactly how high or low the pressure is in the area of the boiler. It is important to know what the manufacturer of your hot water heating system is appropriate as far as low and high numbers, but on average it should be no lower than 12 PSI and no higher than around 24 PSI. The relief valve for pressure helps to quickly push water into the hot water heating system when the PSI level is lower than 12. The pressure reduction valve will remove water from the hot water heating system is the pressure exceed that of approximately 30 PSI. In order to keep your hot water system working appropriately, it is essential that you learn the components and facts regarding those components to perform regular maintenance.
