If you are living in the UK, you should have consistent warm rooms to live in comfortably. For this, warm air systems for home heating are commonly used in certain homes. This type of heating system radiates heat instantly and uniformly in the entire surrounding.

In this blog, we are going to  discuss different types of heating systems, their cost and advantages. We will  also consider the advantages and disadvantages of the warm air heating systems in relation to other systems. First, let’s begin from the history of modern forced air heating.

1970s Warm Air Heating System

In the 1970s, warm air heating systems became a standard option in many UK homes. These systems often used gas-fired units to heat air, which was then distributed through a network of ducts. This period marked a significant shift from radiators to ducted systems, offering instant  heating without the need for large radiators. 

The design was simple, compact, and ideal for new housing developments. However, the oil crisis of the 1970s led to a focus on energy efficiency, prompting improvements in heating system design. Insulation and tighter building regulations became important, influencing the evolution of warm air heating systems.

Four Types of Heating Systems

  1. Forced Air Heating: This system requires a furnace and ducts as heating appliances and air is distributed through vents installed in the walls of the house. It overheats the whole house interior.
  2. Electric Heating: Instals electric heaters to the rooms which are occupied. This is easily done, however, it can be expensive.
  3. Hydronic Heating: Incorporates the circulation of water to generate heat. Water is transported through pipes to radiators or floor systems.
  4. Geothermal Heating: Consists of utilising heat from the ground to heat the buildings. It is cost effective, however the capital expenditure is high.

What is the Most Efficient Heat Source?

Geothermal and air-source heat pumps are the most efficient heating sources in 2024. These heating systems use renewable energy. Geothermal systems rely on heat from the ground, while air-source pumps rely on heat energy present in the ambient air. Both systems help in cutting energy bills and carbon footprints. Their focus is on long-term benefits.

What is Called Warm Air?

Warm air refers to air that has been heated and is above the room temperature.The heat is primarily produced through the use of a heating source, either a furnace, a boiler or a heat pump. Such air will tend to rise in the room while the cooler air will tend to go down.

What is a Warm Air Heating System?

Warm air heating is a unique system for heating indoor spaces. This consists of heating the air first before distributing it in the living room. A heat pump or a furnace is used to heat the air. The heated air is then introduced in the midsection of the rooms through vents, which helps in warming the rooms quickly. The system is meant to operate without the use of radiators or underfloor heating systems.

Types of Warm Air Heating Systems

  1. Gas Fired: Uses gas to heat air, making it affordable and efficient.
  2. Air Source Heat Pumps: Draw heat from outside air, providing efficient warmth year-round.
  3. Ground Source Heat Pumps: Extract heat from the ground, offering high efficiency but costly installation.
  4. Hybrid System: Combines heat pumps with traditional heating for better efficiency and flexibility.

How Does Warm Air Heating System Work?

Warm air heating systems will take cool air into the system, warm it and then re-distribute it to the rooms. Hot air circulation through ducts or vents is enabled by a fan or a blower. A maintenance system is installed to control the warm air heat exchanger within the thermal reservoirs.

Is Warm Air High Pressure?

Warm air is almost always being ducted at a higher pressure than cool air. This enables the air to undergo a vent-dominant flow and warm the respective rooms in a short period of time. Pressure works to ensure that heat is transferred to each part of the house.

Is Warm Air Heating Economical?

Warm air heating can be cost effective, depending on the type of fuel used and the efficiency of the system. Systems powered by gas are cheaper than electric systems. Air-source heat pumps help in reducing the costs of energy. However, the costs related to installation at the beginning stage might be expensive.
