What is a heating system?

A heating system is designed to warm indoor spaces and maintain a comfortable temperature during cooler weather. Different systems can heat a single room, several areas or an entire property.

Heating system definition

A heating system refers to equipment used to provide warmth inside a building. Systems can operate in different ways, from circulating heated air or water to transferring heat into a room.

Main types of heating systems

The type of heating system used depends on the property, the areas that need heating, and how warmth is distributed.

Ducted gas: Sends heated air to rooms through ductwork.
Hydronic: Uses heated water to warm indoor living spaces.
Reverse cycle: Transfers heat from outside air into a room.
Split system: Heats a specific room or smaller indoor area.

How heating systems provide warmth

Heating systems create or transfer heat and distribute it through a space. The method varies by system, ranging from heated air and water to reverse-cycle technology.

Why indoor heating matters

Heating helps maintain comfortable indoor temperatures when the weather turns cold. The right system can provide targeted room heating or warmth across an entire home.

Where heating systems are used

Heating systems are used in homes, workplaces and other buildings. Different options suit different property sizes, layouts and heating requirements.

How heating systems operate

Some systems circulate warm air through ducts, while hydronic systems use heated water. Reverse cycle and split systems transfer heat from outside to warm indoor air.

Common ways heating systems are used

Heating needs vary between properties, so different systems can suit different spaces. Here are some common examples of where each heating option may be used.

Heating the whole home with gas

Ducted gas heating delivers warm air through a network of ducts, allowing multiple rooms throughout the home to be heated from a single central system.

Creating gentle radiant warmth

Hydronic heating circulates heated water through radiators, panels or underfloor pipes to provide comfortable radiant warmth throughout selected areas.
