Underfloor heating and radiators are two popular options for keeping homes warm and comfortable. But have you ever wondered if you can combine the two for an even better heating solution?

The answer is yes! Many homeowners are now opting for a mix of underfloor heating and radiators to enjoy the best of both systems. This combination offers versatility, energy efficiency, and customised warmth for different areas of your home. 

In this blog, we’ll explore how these systems can work together, the advantages they provide, and how to decide the best setup for your space. Whether you’re building a new home or upgrading your current heating system, this guide will help you make an informed decision.

What is Underfloor Heating?

Underfloor heating is a modern heating system installed beneath your flooring, effectively transforming your entire floor into a large radiator. This heating method is highly efficient and discreet, providing a comfortable and consistent warmth across the room.

Unlike traditional radiators, which concentrate heat in a single area, underfloor heating distributes warmth evenly, making your space feel cosy and inviting.

Operating at lower temperatures than radiators due to its extensive surface area, underfloor heating is both energy-efficient and cost-effective in the long run. You can maintain an ideal room temperature without using excessive energy.

This versatile system is compatible with various flooring types, including stone, tile, wood, and carpet. There are two main types: electric underfloor heating (dry systems) and water-based underfloor heating (wet systems).

Installation involves placing heating cables or mats beneath the floor, controlled via a switch or programmable thermostat, enabling you to pre-heat your rooms for a warm and welcoming environment.

Can Underfloor Heating Be Combined with Radiators?

Yes, underfloor heating can be effectively combined with radiators, giving you the flexibility to create the ideal heating solution for your home.

This dual approach has gained significant popularity, particularly in new builds and self-build homes where customised heating systems are highly sought after.

  • Downstairs Heating: Underfloor heating is a perfect choice for ground-floor spaces that are often open-plan and airy. It removes the need for bulky radiators, offering seamless heating while freeing up wall space for furniture and décor.
  • Upstairs Heating: Radiators, towel rails, or electric heating systems are better suited for upper-floor rooms, which are typically smaller and more enclosed. Radiators can provide targeted heating for spaces like bedrooms and bathrooms where underfloor heating might not be practical.

However, underfloor heating can also be installed across the entire home as the sole heat source, depending on your preferences and property requirements. When planning heating systems for upper floors, it’s important to focus on areas that are regularly used to avoid wasting energy.

For smaller rooms, such as bathrooms, heated towel rails are an economical and efficient option, combining warmth with functionality.

Pro Tip: Always ensure that the radiator’s size and BTU (British Thermal Unit) output align with the room’s heating needs for maximum efficiency.

Can Underfloor Heating Replace Radiators?

The short answer is yes—underfloor heating can replace radiators, but it’s essential to determine whether it’s the most efficient choice for your property.

Older homes with poor insulation, draughty windows, or uninsulated walls may not benefit as much, as heat loss can outweigh the efficiency of underfloor heating.

However, for most homes, especially modern builds, underfloor heating offers advanced technology, minimal maintenance, and a sleek, space-saving solution.

Many new-build properties add a mix of underfloor heating downstairs and radiators upstairs, allowing dual thermostats to control temperatures separately for maximum comfort and efficiency.

How is Underfloor Heating Installed?

Underfloor heating can be installed in both new builds and existing properties, although retrofitting it into an older home tends to be more costly. This is because the process often involves lifting existing flooring and making modifications to accommodate the system.

However, the long-term benefits often outweigh the initial expenses, particularly in terms of energy savings and increased property value.

Two Main Installation Methods

  1. Water-Based Underfloor Heating
    • This system involves installing a network of pipes beneath your flooring, which are connected to your central heating system.
    • The system operates similarly to traditional radiators, with the heat source controlled via your boiler and thermostat.
    • It’s particularly well-suited for new builds where the system can be smoothly integrated into the construction process.
  2. Electric Underfloor Heating
    • This system uses heat mats or cables placed under the floor, which are then connected to an underfloor heating thermostat.
    • Electric underfloor heating is easier and quicker to install compared to water-based systems, making it a popular choice for retrofitting.
    • Modern thermostats, including smart ones, allow you to control the system remotely, so you can enjoy a pre-warmed room upon arrival.

While underfloor heating installation costs may seem high initially, especially for retrofitting, the long-term savings in energy bills make it a worthwhile investment.

Additionally, underfloor heating is increasingly seen as a premium feature by potential homebuyers, which can boost the resale value of your property

Conclusion

Combining underfloor heating and radiators offers an excellent solution for efficient, comfortable, and flexible home heating. This pairing works well in various spaces, providing a balance of warmth and energy efficiency. Whether you’re planning a new build or upgrading your current system, this approach ensures a modern and effective way to keep your home cosy year-round.

How to clone into other project?

  • Press "Ctrl + E" or "Cmd + E" in the Designer and enable "Select on-page element".

  • Search for the class named, "Cloneable Area".

  • Copy the element inside this container to your own project.

  • Rename the classes accordingly if they are clashing with your project.

  • Ensure custom code from the in-page setting has been copied into your project as well (if there's any).

  • 'Page Trigger' interaction can't be copied directly. You can only clone the whole project, or rebuild it.
    A simple trick to copy the 'Page Trigger' interaction into another project is as below:

    1. Create a dummy element.
    2. Apply any type of 'Element trigger' into the dummy element and select the 'Page Trigger' animation.
    3. Copy the dummy element with the animations applied into your new project.
    4. The animation should have been copied into your project and you can reapply the 'Page Trigger' animation into your project.

  • If you have further inquiry or need assistance, feel free to contact us.

  • Lastly, please do not copy this project and claim it as your own. We wish to continue sharing and giving to the community. In order to do so, we will need your cooperation and full support. Thank you very much,
