The truth behind Underfloor Heating

Making the right investment for your home heating systems is incredibly important. It can mean the difference between a warm, welcoming and cost-efficient home that you love to return to and an energy-sapping building that guests  and residents struggle to enjoy. Underfloor heating (UFH) systems are rightly gaining popularity and are increasingly on people’s home renovation wish lists. But, as with all technologies their benefits are often muddled by myths and misconceptions.

Myth 1: UFH cannot replace radiators

Reality: Traditional radiators have a number of benefits, but underfloor heating is widely considered to be a superior alternative. With UFH, heat is distributed evenly across the entire floor, eliminating those uncomfortable hot and cold spots often experienced with radiators. This even distribution ensures consistent warmth throughout the space, making it feel welcoming and cosy as soon as you enter the room. Additionally, underfloor heating frees up valuable wall space, which gives you far more freedom to design and decorate your rooms, and move furniture around over time.

Myth 2: UFH is only suitable for new constructions

Reality: Underfloor heating is not limited to new builds; it can be seamlessly retrofitted into existing structures with proper installation methods.

Underfloor heating (UFH) is often perceived as only suitable for new constructions, but the reality is that it can be successfully retrofitted into existing structures with proper installation methods. Despite the initial challenges of installation, such as lifting floors and digging for placement, retrofitting UFH can actually be a cost-effective solution for upgrading older properties. The long-term benefits in terms of comfort and energy efficiency make it a worthwhile investment, outweighing the initial hassle.

It's essential to emphasize that upgrading UFH controls is crucial for maximizing efficiency and effectiveness. Smart thermostats or programmable controllers can optimize energy usage and comfort levels, while wireless or remote control capabilities offer convenient management from anywhere in the property.

In new build properties, UFH installation during construction is seamless and cost-effective, providing numerous advantages over radiator systems. However, regardless of the heating method chosen, upgrading insulation levels in older buildings may be necessary for optimal comfort and energy efficiency.

While the installation process may present challenges, the long-term benefits in terms of comfort and energy efficiency make UFH a worthwhile investment for creating a more comfortable and cozy home.

Installing UFH typically involves lifting floors, but retrofit UFH systems offer a simpler solution by laying on top of existing floors. This minimises disruption, making it suitable for those who want to avoid extensive renovations or are on a tight budget. Conversely, if renovation plans are minimal or budget constraints are a concern, replacing existing radiators or adding new ones may be more practical. Additionally, if you plan to extend the property future-proofing your UFH systems can accommodate any aspirations for expansion.

For example, in the case of a historic home with hardwood flooring, hydronic underfloor heating can be retrofitted by installing water pipes beneath the floorboards. The existing floor can remain intact, preserving the home's original charm while upgrading its heating system for improved comfort and efficiency.

Myth 3: UFH is not energy-efficient

Reality: On the contrary, underfloor heating is a highly energy-efficient solution providing it is designed and installed correctly. By evenly distributing heat across the floor surface, underfloor heating minimises heat loss and reduces energy consumption. Furthermore, by incorporating the handy smart controls we mentioned as well as zoning options we mentioned users can control temperatures precisely and enjoy further energy savings.

For example, hydronic UFH offers energy efficiency by zoning different areas for heating based on occupancy and usage patterns. So, you might choose to leave heating levels low or off altogether in unused rooms or turned them down in bedrooms.  By adjusting the temperature settings for each room, energy consumption is optimised without sacrificing that all-important comfort.

Myth 4: UFH is only compatible with certain flooring types

Reality: Underfloor heating is compatible with a wide range of flooring materials, including tile, wood, laminate and even carpet. However, it is essential to follow specific guidelines for each flooring type to ensure optimal performance and longevity of the UFH system. Proper insulation and heat conductivity are crucial factors to consider when selecting flooring materials for use with underfloor heating.

A good case in point is during a bathroom renovation project. Electric underfloor heating mats can be installed beneath ceramic tile flooring, while avoiding the areas beneath the bath, toilet and any appliances. The heat from the mats warms the tiles directly, providing luxurious warmth underfoot without compromising the integrity of the tile installation.

Myth 5: UFH is not cost-effective

Reality: While the initial installation cost of underfloor heating may be higher than traditional heating systems such as radiators, its long-term benefits far outweigh the upfront investment. UFH offers a remarkable cost-effectiveness compared to traditional radiator systems. It also provides superior thermal comfort even at lower air temperatures. This means that achieving the same level of comfort requires less heat input, meaning more energy savings. Recent studies have demonstrated that this approach can lead to savings of approximately 10% due to reduced air temperatures. Furthermore, for heat pumps, there's an additional efficiency gain of 25% in appliance performance. This combined effect results in potential total cost savings of over 30%. UFH also has an impressive lifespan of over 50 years, far surpassing the mere 8-12 years typical of radiators before they start losing efficiency.

Myth 6: UFH is difficult to control

Reality: Quite the opposite. Underfloor heating systems offer advanced thermostatic controls and zoning options, providing precise temperature management and customisation. Once set up, UFH requires minimal intervention, allowing users to 'set and forget' their preferred temperature settings. As mentioned earlier, zoning controls enable different areas of the house to be heated independently, ensuring optimal comfort and energy efficiency throughout the space.

Zoning controls play a pivotal role in maintaining optimal comfort and energy efficiency within a household. By allowing different areas of the house to be heated independently they ensure that each space is heated according to its specific needs. This means that you can maintain a consistent temperature year-round without the need to adjust the thermostat. Room thermostats also contribute to energy efficiency by accurately achieving the desired room temperature year-round. So, during the summer months when temperatures are higher, the system intelligently refrains from heating, thereby conserving energy, minimising carbon footprint and enhancing overall system performance.

Myth 7: UFH is only suitable for specific climates

Reality: Underfloor heating is effective in a wide variety of climates, thanks to advancements in system design and insulation. In colder climates, UFH provides consistent warmth without the need for additional heating sources, while in warmer climates it can even be adapted for cooling purposes. By utilising the thermal mass of the floor, UFH systems can efficiently regulate indoor temperatures all year-round, regardless of external weather conditions.

For example, in a Mediterranean climate where temperatures tend to soar in the summer months, hydronic underfloor heating systems can be equipped with reversible air and heat pumps to provide both heating and cooling. By circulating chilled water through the underfloor pipes, the system can effectively cool the indoor space during hot weather, offering a comprehensive climate control solution.

Why UFH is the perfect choice for the home

As you can see, the innovative technology behind modern UFH systems offers numerous benefits for homeowners, regardless of where they live and what type of building they live in. From energy efficiency and comfort to versatility and convenience, underfloor heating is a reliable and sustainable heating solution for both new constructions and retrofit projects.

So, with these common myths debunked it’s time to start your journey towards finding a UFH system that will revitalise your home and help you drive down heating costs.
