Underfloor heating (UFH) is no longer considered a luxury, but a practical and energy-efficient way to heat your home. Whether you’re building a new house or renovating, UFH systems can significantly enhance comfort levels while reducing energy costs. This comprehensive guide will help you explore the aspects of installing underfloor heating in a UK terraced house with wooden floors.
What is Underfloor Heating?
Underfloor heating is a form of central heating that achieves indoor climate control for thermal comfort using conduction, radiation, and convection. This system is not a recent innovation; its roots date back to Roman times. Modern UFH systems use either electrical resistance elements ("electric systems") or fluid flowing in pipes ("hydronic systems") to heat the floor. Either type can be installed in a terraced house with wooden floors, providing you with a warm, cosy home.
The popularity of underfloor heating has soared in recent years, and it’s easy to see why. With its ability to provide comfortable, even heat across your rooms, underfloor heating can be a great addition to your home. But if you’re thinking about having it installed, there are a few things you’ll need to consider.
Preparing for the Installation
Before you embark on your UFH project, you need to ensure that your house is ready for the installation. This process involves checking the floors and insulation of your home, amongst other things.
Firstly, you need to establish if your wooden floors are suitable for UFH. Most types of wooden flooring, including engineered wood, are perfectly suited to underfloor heating. However, you should always check with the manufacturer to ensure that your specific type of wooden floor is compatible.
Insulation is another crucial aspect of preparing for UFH installation. Heat tends to move from warmer to cooler areas, and without sufficient insulation, heat from your underfloor heating could escape into the ground, causing the system to work harder and thus increasing your energy costs. It’s therefore paramount to invest in good-quality insulation to maintain the efficiency of your underfloor heating.
Choosing the Right UFH System
Selecting the right UFH system is crucial. There are two main types of underfloor heating systems: electric and hydronic (water-based). The choice between these two systems will largely depend on your specific needs, budget, and the nature of your project.
Electric Underfloor Heating Systems
Electric heating systems often come in the form of heating mats, which are embedded within the floor structure. These mats are then connected to your power supply and controlled by a thermostat. This system is typically simpler to install, making it a popular choice for retrofit projects. However, it’s worth noting that while the installation costs may be lower, electric UFH tends to be more expensive to run than its water-based counterpart.
Hydronic Underfloor Heating Systems
Hydronic or water-based underfloor systems work by pumping a mixture of water and antifreeze through a series of pipes that are laid beneath your floor. These systems tend to be more efficient to run than electric UFH, making them a popular choice for larger projects or new builds. However, the installation process is often more complex and costly, and the system takes up more floor space.
The Installation Process
The installation process for underfloor heating can be complex, and it’s often best to involve a professional to ensure the job is done correctly. The process varies depending on the type of system you choose and the current state of your home.
Installing an electric system typically involves laying heating mats beneath your wooden floor. These mats need to be appropriately spaced and connected to a power source and thermostat, which can usually be done without too much disruption to your home.
Installing a hydronic system, on the other hand, is more complex. It involves laying pipes beneath your floor, connecting them to a boiler or heat source, and then installing a manifold to control the flow of water. This process can be more disruptive and may require lifting your floors completely.
Understanding the Costs
One of the most important aspects of any home improvement project is understanding the costs involved. The cost of installing underfloor heating will depend on a range of factors, including the size of your project, the type of system you choose, and the layout of your home.
Electric systems tend to be cheaper to install but more expensive to run, making them best suited for smaller areas or rooms that aren’t frequently used. On the other hand, hydronic systems are more cost-effective for larger areas and new builds, but their installation costs can be significantly higher.
Remember to factor in not only the upfront costs but also the long-term operating costs when planning your project. This will help you make an informed decision on the best type of underfloor heating system for your home.
Post-Installation Essentials
Once your underfloor heating system is installed, you should take some steps to ensure its optimal performance. Indeed, taking good care of your new heating system will prolong its lifespan and maintain its efficiency over time.
Balancing and Commissioning
After the installation of your UFH, balancing and commissioning of the system are necessary steps. Balancing involves adjusting the flow rates through the UFH system to ensure heat is evenly distributed across the floor surface. Commissioning, on the other hand, involves setting up and checking the system controls, including the thermostat and timers. It’s essential that you involve a professional to execute these tasks to ensure the system runs smoothly and efficiently.
Care and Maintenance
Underfloor heating systems are generally low maintenance. However, a periodic check is advisable. For hydronic systems, regular inspection of the boiler or heat pump is essential to ensure it is functioning correctly. For electric underfloor heating systems, a simple visual inspection of the thermostat and any exposed wiring can suffice.
Floor Coverings
Choosing the right floor coverings is crucial post the installation of your UFH system. Some options work better with underfloor heating than others. For example, tiles and stone have a high thermal conductivity, which means they transfer heat efficiently. Wood and carpet, on the other hand, have a lower thermal conductivity, meaning your UFH may have to work harder to heat your rooms. Therefore, you should consider the type of floor covering in your house plans and make an informed choice.
Conclusion: Is Underfloor Heating Worth It?
In conclusion, underfloor heating is an efficient, comfortable and modern way to heat your home, especially if you’re planning an extensive renovation or building a new home. The decision to install UFH should be based on a thorough understanding of the process, costs, and maintenance involved.
While the upfront expenses of a hydronic UFH system can be high, they can prove cost-effective in the long run due to their efficiency, particularly in larger areas or new builds. Alternatively, electric underfloor heating systems, while cheaper to install, may be more costly to run, but they may be suitable for smaller projects.
In any case, it is advisable to involve a professional from the start of your project. This will ensure that your system is correctly installed, balanced, commissioned, and maintained, contributing to its efficiency and longevity. With this complete guide, you are now well-equipped to make an informed decision about the suitability of underfloor heating for your terraced house with wooden floors.
Remember, the key to a successful underfloor heating project lies in careful planning, selecting the right system, using quality materials, and following the design installation process meticulously. Once completed, the comfort and warmth provided by your underfloor heating system will make it a worthy addition to your home.
