Introduction
People used to think that warm air heating systems were modern and worked well, but now they are old-fashioned, not very useful, and costly to keep up. Many homes in the UK are increasingly moving to central heating systems since they are more comfortable, work better, and save money. This tutorial will tell you why and how to switch from warm air heating to central heating. It will also cover the expenses, benefits, grants, and how to install it.
What is a warm air heating system?
Through the process of first drawing in air, then heating it in a central unit, and finally distributing the heated air throughout the home through ducts and vents, a warm air system is able to function properly. The system repeats this process indefinitely until it achieves complete functionality. Additionally, you will need a separate water heater because warm air heating systems do not provide hot water like modern boilers do. This means that you will need to purchase a water heater.
Why are warm air heating systems outdated?
- Poor energy efficiency
- Uneven heating throughout the home
- No hot water supply
- Difficult and costly to repair due to outdated parts
- This system produces higher carbon emissions when compared to a central heating system.
Why choose a central heating system instead?
You can use the same tools to heat your home and get hot water if you have central heating. Because it was made to heat the whole house, this is what happens. Radiators keep the house warm by distributing heat throughout it. It’s better to live in when it gets warmer inside. Radiators send heat to all the right places
Key benefits
Energy Efficiency: An A-rated boiler saves fuel and money.
Hot Water on Demand: perfect for modern family life.
Even Heat Distribution: each space remains warm and pleasant.
Lower bills: decreased energy use over time.
Easier Maintenance: spare parts and service are easily accessible.
Environmentally friendly: lowers carbon footprint.
Installation process
Radiator Fitting: installing radiators in every room.
Pipework Installation: connecting boiler and radiators.
Testing & Handover: ensuring safe and efficient operation.
How long does the installation process take?
It is typical for the process of switching from a warm air system to a central heating system to take anywhere from three to five days to complete. Both the size of the property and the level of difficulty involved in the operation will play a role in determining the exact amount of time that will be necessary to finish the procedure.
Eligibility for grant
You may qualify if:
- You receive certain income-related benefits.
- Your property has an EPC rating of E, F, or G.
- You are a pensioner or in a low-income household.
- You are off the gas grid but eligible for first-time heating support.
Cost of replacing an air system with central heating
The typical cost ranges between £4,000 and £7,000. The price depends on:
- Number of radiators required
- Size of the property
- Boiler type chosen
- Labour and material costs
Eco-friendly benefits of central heating
In the future, boilers that are compatible with renewable technologies, such as air source heat pumps, will be more beneficial to the environment than boilers that are now in use since they produce fewer carbon emissions. This may be the case because these boilers emit less carbon dioxide. This is because these boilers will work better. Since this is the case, the utilisation of central heating is a consequently future-proof choice.
Warm air vs central heating
| Feature | Warm Air System | Central Heating System |
| Energy Efficiency | Low | High (A-rated boilers) |
| Hot Water Supply | No | Yes (with combi boiler) |
| Running Costs | Expensive | Lower in the long run |
| Comfort Level | Uneven heat | Even heating across rooms |
| Spare Parts Availability | Limited | Easily available |
Who should consider switching?
- Homeowners with outdated warm air systems
- Families need heating and hot water together.
- Low-income households seeking grants
- Anyone looking to reduce monthly energy costs
- Homeowners are planning to sell and increase property value.
FAQs
Do I need new pipes?
Yes, you normally need new pipes and radiators.
Will I not have heat while the installation is going on?
Yes, but only for a short time (3–5 days).
Am I able to pick the kind of boiler?
Yes, it depends on how big your land is and what you require.
Is it cheaper to use central heating than warm air?
Indeed, it significantly reduces costs over time.
What do I need to do to get a grant?
You can apply through energy companies or ECO4 providers that have been approved.
