Marley Debuts Next Generation of Hidden Comfort, THX Series In-Floor Convector

Marley Engineered Products is excited to launch a ground-breaking new product: the out-of-sight, out-of-mind UL listed In-Floor Perimeter Convector – THX Series heater, which delivers comfort, aesthetics and safety for the ultimate supplemental heat system for both new and existing buildings. THX Series (Trench Heater Experience) directly addresses the building's need for supplemental heat against the curtain walls and glazing (perimeter heater), while fully integrating with the architects' designed interior spaces. The unit drops directly into the floor, leaving only the grille visible, for unobstructed sightlines and more free space for amenities.


Architects looking to integrate hidden supplemental heat should look no further. The THX in-floor convector heater’s zero vertical profile discreetly adds supplemental heat to fully-designed interior spaces without compromising the aesthetic vision, delivering the environmental comfort clients demand.

The benefits of the THX Series go beyond clarity. The THX provides an effective draft barrier that works like a standard convector to protect a building’s curtain walls and prevent drafts, condensation and freezing near exterior windows. Keeping interior aesthetics intact, THX helps open rooms to natural light and outdoor scenery as it clears windowed surfaces of fog and moisture.

The THX Series also supplement’s a building’s HVAC system and prevents it from becoming overtaxed, and avoiding inefficiency with higher utility costs. The convection draft barrier improves overall HVAC performance for an environmentally-friendly heat solution and the first line of defense in lobbies, waiting rooms and other areas with heavy foot traffic.


The flexibility and configuration options of Marley’s THX makes it a perfect fit for a variety of unique heating needs. With a leading three UL approved mounting options and a wide range of aesthetic finishes and accessories, the THX provides an opportunity to upgrade the design and aesthetics of any room while lowering overall HVAC costs.

The THX Trench Heater is not only the most compact in-ground comfort solution available, but it boasts the highest output/cu.ft. of any pure convection, in-floor electric heater on the market(1). The THX creates an effective draft barrier that improves overall HVAC performance with no fumes or exhaust for an environmentally-friendly heat solution. Designed with durability in mind, all THX units include features focused on water and debris management - UL approved, sealed junction boxes and debris catch screens to name a few.

THX saves time, effort and money with modularized units that can be configured by one service professional for easy field connection, control and installation. Additionally, each and every unit is factory wired and preassembled for out-of-the-box readiness, drop-in installation, and easy access for cleaning and maintenance.

Welcome to the future of supplemental heat with customized, hidden comfort!
