Would you like to learn about the most important parts of a heating system?

There might be over a dozen parts for your heating system, but out of these only a few are the most important ones. Every heating system requires these parts as without them it cannot function. While buying these parts make sure you look for ones with the highest quality. If you can get the basic building blocks of a heating system rightly installed, you can be sure of living in a warm and comfortable home.

We have listed the most important parts of a heating system below...

The Furnace:

Of all the parts, the furnace is probably the most important one. The fuel whether it is gas or electricity is converted to heat energy in the furnace and then transferred to the air that gets sucked in. This air is then transferred through ducts to the various parts of the house. In homes that are kept warm through hot boiling water (circulated through pipes), a boiler is used in place of a furnace.

Always ensure you get the latest furnace that is both environment and resource friendly i.e. it runs smoothly while using the least resources.

The ducts:

As mentioned above, the furnace transfers hot air with the use of ducts. They are distributed throughout the entire house. Well fitted ducts will ensure that they transfer maximum heat without any leakage. Leakage can cause all the work done by the furnace and the resources consumed to go to waste. To prevent this check them regularly for leaks.


A good thermostat will help you maintain the exact temperature you need through the entire house. You can just use one for the entire house or you can install one in each room if people in your house prefer different temperatures. For better results you could pair it with a good hygrometer.

Other important parts you need to make a note of are the heat exchanger, evaporator coil, condensing unit, vents and refrigerant lines.
