The concept of a boiler is pretty understandable, but there are always key components. Boilers include various parts such as a burner, heat exchanger, circulator, which is also known as a pump, and a main control system. Once the house where the boiler is installed cools down, the main control system in the boiler tells the system to start heating up the water. This control operates to maintain the water temperature at which it is required. As water travels through the pipes and heats up, this allows the room to heat up to the desired temperature.

The lifespan of a boiler can be affected by various factors. Some of these factors include but are not limited to how well the unit is maintained, how the system is designed to work with the specific boiler and the quality of water that is being flowed through the boiler. Typically, Navien boilers have a 10-15 year residential warranty (dependent on the model). The lifespan of a well maintained boiler is expected to last up to 20 years, possibly a little longer.
