Why Ultra-Core™

Optimized for Low Water Temperatures.

When moving from traditional boilers to low-temperature heat sources such as air-to-water heat pumps, standard radiators often need substantially more surface area to deliver the same room heat output.

Most homes were never designed around oversized radiators.

Ultra-Core wall convector panels are designed for low-temperature systems, delivering comfortable radiant and convective heat without sacrificing valuable floor space.

Discreet grilles only
Many homes can use a heat pump. Few were designed around oversized radiators.
Larger radiators reduce usable wall space.
Lower water temperatures require more emitter area.
Oversized radiators dominate interiors
Ultra-Core places the emitter within the wall, leaving only discreet grilles visable.

Ultra-Core™ Wall Convector Panels

Modular Radiant and Convective Heating. Replace Bulky Radiators. Reclaim Space. Simplify Design.

Ultra-Core panels integrate into standard wall framing to deliver discreet radiant and convective heating without projecting into the room.

Enjoy consistent warmth, more usable space and greater design freedom throughout the space.

Built-In integration: Installs within standard wall framing, leaving only slim upper and lower grilles visible.
Compatible wall finishes: Suitable for drywall, plaster and wood panelling when installed according to specifications.
Natural convective airflow: Room air enters through the lower grille, passes across the heated panel and returns throught the upper grille.
Space-Saving Design: Does not project into the room, preserving usable wall and floor space.
Standard Height-90 inch (2286 mm): Designed to fit within standard wall-framing configurations.
