Ideal Hydronic System for Projects of All Sizes

As a reformulation of Warmup’s popular Total-16 System, the VLo Ultra-12 Low Build System is an ideal floor heating solution for both home renovations and new-build construction projects where floor height is at a premium and installation speed is of the essence. Its unique design makes it particularly suitable for projects with uninsulated floors.

Adding only 18mm to the floor build up, the Ultra-12 offers true ease-of-use and is suitable for installation with almost all floor finishes including: solid and engineered wood, ceramic or stone floors as well as vinyl and carpet. The system’s energy-efficient technology offers low running costs, and it can be used with both traditional boilers and heat pumps.   


Built-in Insulation for a Responsive Heating Solution

The VLo Ultra-12 System offers a dry installation method for floating floors and features built-in high-quality insulation and a 150μm diffuser for efficient heat spread. It uses dedicated heating, end, service and plain panel types, making it ideal for rooms of any size and shape.

The Ultra-12 uses Warmup’s new and improved 12mm PERT heating pipe and features a recycled fleece decoupling layer on both the base and top of the Ultra-12 Low Build Panels for a fast and secure installation. Its low-weight construction provides a smooth and hassle-free installation.
