    Whether you’re renovating a spacious living room, a chilly basement, or a high-traffic kitchen, this high output joist kit provides the powerful heating solution you need, ensuring that every inch of your space is comfortably warm, no matter the outside temperature.

    The standard output kits use 150mm pipe centres; ideal for conservatories and spaces with a higher heat loss!

    Why Choose High Output Underfloor Heating?

    For spaces that demand more heat, our High Output Underfloor Heating Joist Kit offers an exceptional solution. This system is designed to produce higher temperatures efficiently, making it ideal for rooms with higher ceilings, larger floor areas, or where additional warmth is essential. By eliminating the need for radiators, you gain more design freedom, while enjoying consistent, even heat that enhances the comfort and ambiance of your home.

    Key Features of the High Output Underfloor Heating Joist Kit:

    1. Superior Heat Output:
    This kit is engineered to deliver a higher heat output, ensuring that even the coldest rooms are warmed effectively. It’s perfect for spaces that require extra heat, such as large open-plan areas, conservatories, or rooms with significant heat loss.

    2. Energy Efficiency:
    Despite its higher output, this system remains energy-efficient, operating at a low temperature to ensure minimal energy consumption. It’s an eco-friendly choice that helps reduce your household’s carbon footprint while keeping your energy bills under control.

    3. Consistent and Even Heating:
    Unlike traditional radiators that can create uneven temperatures and cold spots, our underfloor heating system provides uniform warmth across the entire floor. This consistent heat distribution creates a more comfortable environment, reducing the need for additional heating sources.

    4. Space-Saving Design:
    By installing heating beneath the floor, you eliminate the need for bulky radiators, freeing up wall space and giving you more flexibility in room design. This discreet system remains completely hidden, allowing you to create a sleek and modern aesthetic in any room.

    5. Versatile Compatibility:
    Our High Output Underfloor Heating Joist Kit is compatible with a wide range of floor coverings, including tiles, stone, wood, and laminate. No matter your flooring choice, you’ll enjoy warm and inviting floors that enhance the overall comfort of your home. Please note, when using any type of wooden flooring, a floor sensor must be used in each room to limit the floor temperature to 27°c.

    6. Easy Installation:
    The kit is designed for straightforward installation between joists, making it accessible to both professional installers and experienced DIYers. With pre-sized components and clear instructions, you can achieve a hassle-free installation, even in challenging spaces.

    7. Safe and Reliable:
    Safety is built into the design of our heating systems. With features that prevent overheating and ensure long-term reliability, you can enjoy the warmth and comfort of underfloor heating with complete peace of mind. The system is also thermostat-compatible, offering precise control over your room’s temperature.
