Another important stage in the construction process was completed with the installation of the underfloor heating system and the pouring of the liquid floor screed.
These elements, though ultimately hidden, are essential to the comfort, efficiency, and thermal performance of the finished home.
Underfloor Heating Installation
Inside the property, the underfloor heating (UFH) pipes from Frankische were carefully laid throughout the floor areas before being secured into position using clip rails.
The underfloor heating we install in our timber frame homes is a wet system, designed specifically for each individual project. Every system is carefully planned to take into account the property’s heat loss calculations, room layouts and required heat output, ensuring the home performs as efficiently as possible.
Unlike conventional radiators, underfloor heating distributes warmth evenly across the entire floor surface. This creates a consistent and comfortable temperature throughout each room, particularly beneficial in large open-plan living spaces where traditional heating systems can often leave colder areas.
Energy Efficiency Benefits
One of the biggest advantages of underfloor heating is its efficiency. Because the system operates at lower water temperatures than traditional radiators, it requires less energy to maintain comfortable room temperatures. This can help reduce energy consumption and lower heating bills.
When combined with our highly insulated timber frame construction, airtight building methods and triple glazing, underfloor heating becomes part of a complete energy-efficient package. Together, these elements help create homes that are warm, economical to run and designed for modern living.
Underfloor heating is also perfectly suited to renewable heating technologies such as air source heat pumps. As ASHP systems work most efficiently at lower flow temperatures, pairing them with underfloor heating can significantly improve overall system performance and long-term running costs.
Design Flexibility
Another major benefit of underfloor heating is the flexibility it offers when designing interior spaces. As the heating pipes are hidden beneath the floor, there is no need for wall-mounted radiators taking up valuable space or limiting furniture positions.
This gives homeowners greater freedom when planning room layouts, while also contributing to a cleaner, more minimalist appearance throughout the home.
Liquid Screed Installation
Once the heating pipes were secured in place, the next stage involved pouring 50mm of Cemfloor liquid screed across the floor.
Liquid screed has become increasingly popular in modern construction due to its excellent thermal performance, efficiency and self-levelling ability.
This type of screed pairs perfectly with underfloor heating systems, as the flowing nature of the liquid allows it to fully encapsulate the pipes, removing air gaps and ensuring efficient heat transfer throughout the floor.
Compared to traditional sand and cement screed, liquid screed can often be installed more quickly as it is pumped directly onto the surface covering large areas, and it also dries faster, allowing other trades to continue work quickly.
Its flat and smooth finish provides an ideal base for the final floor coverings later in the build process.
Frequently Asked Questions
How does underfloor heating work?
Underfloor heating (UFH) works by circulating warm water through pipes installed beneath the floor surface. The heat rises evenly from the floor upwards, creating a comfortable and consistent temperature throughout the room. Unlike traditional radiators that heat one area intensely, UFH distributes warmth evenly across the entire floor space.
What are the main advantages of underfloor heating compared to radiators?
Underfloor heating systems are a popular choice for those building their own home as they come with several advantages. Underfloor heating provides even, consistent warmth across the entire room, compared to radiators which can create hot and cold spots. It is also more energy efficient as it operates at lower temperatures, helping reduce heating costs. Because the system is hidden beneath the floor, it frees up wall space and gives greater flexibility for furniture layouts and interior design.
Why is liquid screed used with underfloor heating?
Liquid screed is ideal for underfloor heating because it flows easily around the heating pipes, completely covering them and removing any air gaps. This improves heat transfer and allows the heating system to work more efficiently.
What floor coverings can be used over liquid screed with underfloor heating?
Liquid screed provides a smooth, level floor finish which is perfect for a wide range of final floor coverings, including;
- Engineered timber
- Laminate flooring
- Tiles
- Carpets
- Vinyl flooring
- Polished concrete
It is important to choose floor coverings compatible with underfloor heating to ensure efficient heat transfer and long-term performance.
Is underfloor heating energy efficient?
Yes, underfloor heating is highly energy efficient because it operates at lower temperatures than traditional radiators while still maintaining comfortable room temperatures. When combined with high insulation levels, airtight construction and modern heating systems such as air source heat pumps, UFH can help minimise energy consumption and keep heating bills low.
