The 7 Essential Factors To Consider When Choosing Underfloor Heating Or Insulation

Are you tired of stepping on cold floors and chilly rooms during the winter months? If so, you might be considering installing an underfloor insulation system. But with so many options available on the market, choosing the right underfloor heating system can be a daunting task. That's why I've compiled a list of the five essential factors you should consider when making this important decision. From determining the type of underfloor heating that suits your needs to understanding the installation process, there’s a lot to consider.

Types of underfloor heating or insulation materials


Electric Underfloor heating

Electric underfloor heating systems consist of a series of electric cables or mats installed beneath the flooring. These systems are relatively easy to install and are ideal for smaller areas or individual rooms. It can also be controlled independently for each room, allowing for precise temperature control. However, there are some downsides to fitting electric heating systems. One is that it may have higher running costs compared to water-based systems, especially for larger homes.

Water-based Underfloor heating

Water-based underfloor heating systems, also known as hydronic systems, use a network of pipes to circulate heated water beneath the floor. These systems are typically connected to a central boiler or heat pump, making them suitable for whole-house heating. They offer excellent energy efficiency and can be controlled using the existing central heating controls. However, they require professional installation and may be more expensive upfront than electric heating systems.

Underfloor Insulation Materials

When it comes to floor insulation materials, there are several you can choose from, each with its own unique properties. Fibreglass is one of the popular options that is both affordable and effective, while cellulose insulation is an eco-friendly choice made from recycled materials. Mineral wool, on the other hand, is an excellent choice for soundproofing and fire resistance. For homeowners looking to improve their home’s energy efficiency, spray foam insulation is one of the most effective and non-disruptive options, especially for suspended floors. Ultimately, the best insulation material will depend on your specific needs and budget, so consider your options carefully before making a decision.

Factors to consider


Energy Efficiency

When it comes to choosing the right underfloor insulation system, energy efficiency should be at the top of your list. Not only does an energy-efficient heating system help reduce your carbon footprint, but it also saves you money on your energy bills in the long run. One of the key factors that contribute to the energy efficiency of underfloor heating is the type of insulation material used, since some types of insulation are more efficient at retaining the heat and preventing it from escaping through the floors. Moreover, extra insulation materials such as foam boards or reflective foils can be installed underneath the heating system to minimise further heat loss.

Flooring Type

The type of flooring in your home will also impact your selection of underfloor insulation. Different flooring materials have different thermal conductivity properties, meaning they transfer heat at different rates. For example, tiles and stone have excellent thermal conductivity and are ideal for electric or water-based underfloor heating, while suspended floors may require board or blanket insulation, such as spray foam or glass wool insulation.

Room Size And Layout

The size and layout of the room also play an essential role in determining the type of underfloor heating system that will work best for your home. Smaller spaces, such as bathrooms or kitchens, may require a different underfloor heating system than larger living areas or bedrooms. Additionally, the layout of the room, including the presence of furniture or fixtures, can affect heat distribution. It's essential to evaluate the specific heating requirements of each room to ensure optimal comfort.

Heating System Compatibility

Before investing in underfloor heating, it is also a good idea to check to see if your current heating system is compatible with it. If you have a central heating system, water-based underfloor heating may be the best option, as it can be easily integrated into the existing boiler system. However, if you have electric heating or are looking to heat a specific area, electric underfloor heating might be more suitable. Also, because every property is unique, it’s important to consult with a heating professional to help you assess the compatibility and feasibility of different heating systems.

Control Options And Programmability

Having control and flexibility over your underfloor heating system is also crucial for maintaining comfort and energy efficiency at home. If possible, look for underfloor systems with programmable thermostats that allow you to set specific temperature schedules for different times of the day or week. You can also consider getting smart thermostats with mobile app integration that can provide even more control, allowing you to adjust the temperature remotely or monitor energy usage at your fingertip.

Maintenance And Warranty

Like any heating system, underfloor heating requires regular maintenance to ensure optimal performance. So before you make a purchase, inquire about the maintenance requirements and warranty coverage, as some underfloor heating systems may require professional maintenance, while others can be easily maintained by the homeowner. A comprehensive warranty can also provide peace of mind and protect your investment in the event of any unforeseen issues.

Budget Considerations

Last but certainly not least, your budget will play a significant role in the selection process. Underfloor heating systems can vary greatly in terms of cost, depending on the type, size, and complexity of the installation. It's important to set a realistic budget and explore different options within that range. While it may be tempting to opt for the cheapest option, investing in a high-quality and energy-efficient system, such as spray foam insulation, will often provide long-term benefits and savings.
