Warm Air Heating Systems: A Modern Solution for Sustainable UK Home

In the ever-evolving world of home heating, warm air heating systems have re-emerged as a sustainable and efficient choice for modern UK homes. Though these systems may have faded with the arrival of water-filled radiators and central heating, they are now making a comeback, proving to be an eco-friendly and cost-effective solution. In this blog post, we'll delve into the realm of warm air heating, exploring its definition, operation, and why it might be the ideal solution for your British home.

What Is Warm Air Heating?

Warm air heating, also known as ducted air or dry systems, is a heating method that waned in popularity in the UK when water-filled radiators supplied by boilers took over. However, warm air heating is regaining ground as an energy-efficient choice. Warm air heating systems, such as air source heat pumps, offer several compelling advantages:

  1. Eco-Friendly: Warm air heating is kinder to the environment, contributing to reduced carbon emissions.

  2. Quick and Direct: These systems swiftly and precisely heat specific areas, making them ideal for well-insulated homes that retain heat effectively.

  3. Dual Functionality: Some warm air systems offer cooling capabilities, making them versatile for both winter and summer use.

How Does Warm Air Heating Work?

Warm air heating systems function by drawing in cool outside air, heating it, and then circulating it throughout the house via air ducts, vents, or grills. A thermostat controls the system, and individual room temperatures can be adjusted by opening or closing vents. The system operates in standby mode until the temperature falls below the set limit, at which point it resumes heating.

Air source heat pumps, a popular warm air heating system, work by transferring heat to a coolant, which is then compressed into hot, dense vapour. Fans blow out this heat through vents to warm the room.

Other warm air heating systems include:

  • Gas-Fired: Heats outside air over a gas flame and can also be used for hot water.

  • Air-to-Air Heat Pump: Uses electricity to move air for heating and can be combined with other systems for hot water.

  • Ground Source Heat Pump: Harnesses heat stored in the ground, circulating warm air through your home's ventilation system.

  • Hybrid Heat Pump: Combines a heat pump with a boiler for efficient heating and hot water, especially suitable for high heat demand homes.

Can You Change Warm Air Heating to Radiators?

Yes, it's possible to switch from warm air heating to water-filled radiators. This process involves installing a new system and removing old components. Keep in mind that radiators require space in each room they occupy, potentially affecting furniture placement. Warm Air Heating vs. Radiators

Warm air heating and central heating radiators differ in how they heat and distribute warmth. Warm air systems are dry, heating and circulating air through vents, while radiators are part of wet systems, using water to heat the home. Radiators are common in the UK, often heated by gas boilers.

Cost of Upgrading Warm Air Heating

Upgrading to a modern warm air heating system, like an air source heat pump, typically costs between £6,000 and £14,000, depending on your home's size, radiator requirements, and preferred fuel type. Despite the initial expense, you'll enjoy long-term benefits, including a reduced carbon footprint and lower energy bills, thanks to modern, energy-efficient systems.

Warm Air Heating Systems Pros and Cons

Warm air heating systems have distinct advantages and disadvantages worth considering:

Advantages of Warm Air Heating Systems

  • Modern warm air heating systems provide fast and silent heating for your home.

  • They free up valuable space by eliminating the need for radiators, making them suitable for smaller properties.

  • Warm air systems are energy-efficient and can cost up to 18% less to run compared to other heating systems.

  • Some warm air systems feature additional filtration to remove pollen, dust, and bacteria from the air.

  • Air source heat pumps are low-carbon heating systems, reducing your home's carbon footprint by not releasing CO2 into the atmosphere, unlike gas boilers.

  • Grants are available to help cover the cost of installing an energy-efficient warm air heating system.

Disadvantages of Warm Air Heating Systems

  • Many warm air systems cannot provide domestic hot water, necessitating an additional boiler.

  • Installing a warm air heating system in an existing house can be challenging as the ducts and vents will be visible.

  • The initial cost of installing a warm air heating system can be relatively high.

  • Due to limited heat pump manufacturers and installers, there may be high competition, resulting in higher costs and fewer choices.
