Why Residential Homeowners Love the Lennox TUA
For homeowners, garages are no longer just for parking vehicles. They’ve become workout rooms, woodworking shops, art studios, and even gaming lounges. But without proper heating, these spaces sit unused during the long winter months.
Here’s how the TUA heater helps reclaim your garage space:
✔ Even Heating – Heats quickly and distributes warmth evenly across the entire space.
✔ Quiet Performance – Unlike loud space heaters, the TUA operates quietly—ideal for residential settings.
✔ Durability – Built with corrosion-resistant materials and heavy-duty components for years of reliable service.
✔ Compact Installation – Ceiling-mount design saves floor space and allows more room for tools, storage, or activities.
By transforming your garage into a usable, warm space year-round, you not only increase comfort—you add usable square footage to your home.
Ideal for Commercial and Light Industrial Use
The Lennox T-Class™ TUA Garage Heater is not just for residential garages—it shines in commercial environments where temperature control matters but central heating may not be practical.
It’s ideal for:
✔ Auto repair shops – Keeps technicians warm and productive through the winter.
✔ Loading docks – Prevents freezing conditions near frequently opened bay doors.
✔ Warehouse break rooms or storage areas – Protects both people and sensitive materials.
✔ Commercial maintenance garages – A reliable heat source for high-traffic, high-demand spaces.
What sets the TUA apart in commercial settings is its high thermal efficiency and rugged construction, capable of withstanding the wear and tear of daily use in busy environments. You’ll also appreciate the low maintenance requirements and the option to integrate it into your facility’s ventilation or control systems.
