ProWarm™ LoFlo™: Revolutionizing Floor Heating

Introducing ProWarm™ LoFlo™, the groundbreaking low-profile floor heating system that is perfect for both renovation projects and new builds. With its slim and sleek design, this system can be installed directly over the existing floor, requiring a mere 18mm depth. Say goodbye to costly excavations or raising the floor to unacceptable levels. ProWarm™ LoFlo™ offers a convenient and cost-effective solution that brings comfort to any space.

The ProWarm™ LoFlo™ panel is meticulously engineered to cater to heavyweight floor coverings such as ceramics or engineered wood that require direct fixing. Crafted from durable and high-quality fibrous materials, this panel provides a stable and secure surface for your floor covering, ensuring exceptional longevity and optimal performance over time.

ProWarm™ LoFlo™ systems utilize a 12mm pipe with 150mm pipe centers, delivering remarkable response times and superior heat output. Compared to traditional built-in underfloor heating solutions, ProWarm™ LoFlo™ surpasses expectations in terms of performance and efficiency. It is suitable for both traditional heating systems and low-temperature renewable systems, making it the ideal choice regardless of your setup. Whether you opt for a conventional heating system or an eco-friendly one, ProWarm™ LoFlo™ provides unparalleled heating comfort.

One of the unique features of the ProWarm™ LoFlo™ system is its end support, which allows installers to easily 'SNAP-OFF' sections as needed. This allows for effortless customization, leaving the desired number of channels around the edge of the room. With this innovative feature, the installation of leaders and perimeter loops becomes remarkably straightforward and efficient, saving time and effort.

ProWarm™ Water Underfloor Heating Kits are proud to offer lifetime warranty.

✅ The ProWarm™ Water Underfloor Heating Kit has WRAS-approved pipe; this indicates that the Pert-Al-Pert Pipe as part of this product has been thoroughly tested to demonstrate it is of suitable quality and standard against the requirements of the Water Fittings Regulations and Scottish Byelaws.

ProWarm™ Water Underfloor Heating Kit Components

Below, we provide examples of the components that could be included in your ProWarm™ Water Underfloor Heating Kit. For the exact manifold size and pipe length suitable for your chosen kit, please refer to our convenient kit content comparison table below.

  • Grundfos Mixing Unit: The A-rated UPM3 Grundfos Manifold Pump/Mixing Valve Unit ensures efficient mixing and distribution of the heated water within the system. This unit plays a crucial role in maintaining the desired temperature and providing even heat distribution throughout the zones.
  • Manual Thermostat: Enhance your control options by upgrading to a digital, programmable, wireless, or touchscreen thermostat for a small additional fee. This upgrade offers advanced functionality, allowing you to easily adjust and schedule the heating settings according to your preferences and lifestyle.
  • Manifold: The stainless steel manifold with an adjustable flow meter enables easy balancing of the system. The manifold comes factory pre-assembled on fixing brackets, simplifying the installation process and ensuring optimal water flow management.
