Recommended brands for hydronic heating under the floor include Uponor, Viega, Roth, and Warmboard, known for their reliability, efficiency, and advanced technology in radiant heating systems.
Hydronic underfloor heating provides efficient, comfortable warmth by circulating heated water through tubing beneath your floors. Choosing the right brand ensures reliability, performance, and longevity. Here are the top recommended brands for hydronic heating systems.
Best Hydronic Heating Brands
1. Uponor
Uponor is a leader in PEX tubing systems, known for durability and flexibility. Their cross-linked polyethylene (PEX) pipes resist corrosion and scaling, making them ideal for radiant floor heating. Uponor’s systems are compatible with various heat sources, including boilers and heat pump water heaters.
2. Rehau
Rehau offers high-quality PEX tubing with excellent thermal conductivity. Their RAUPEX system is oxygen-barrier certified, preventing corrosion in metal components. Rehau’s solutions work well with both new constructions and retrofits.
3. Viega
Viega specializes in press-fit piping systems, ensuring leak-free connections. Their MegaPress and PureFlow PEX systems are popular for hydronic heating. Viega’s products are easy to install and maintain.
4. Watts Radiant
Watts Radiant provides complete hydronic heating solutions, including tubing, manifolds, and controls. Their systems integrate seamlessly with vented gas heaters and boilers.
5. Warmboard
Warmboard combines aluminum panels with PEX tubing for fast heat transfer. This system is ideal for hardwood and tile floors, offering even warmth without hot spots.
Key Features to Consider
Material Quality
PEX tubing is the standard for hydronic systems due to its flexibility and resistance to freezing. Oxygen-barrier PEX prevents corrosion in metal components.
Compatibility with Flooring
Tile and stone work best with hydronic heating due to their high thermal mass. Engineered wood and luxury vinyl plank (LVP) are also suitable if installed correctly.
Heat Source Options
Hydronic systems can pair with:
- Gas boilers
- Electric boilers
- Heat pumps
- Solar thermal systems
Installation Tips
Subfloor Preparation
Ensure the subfloor is clean, level, and properly insulated. Reflective insulation panels improve efficiency by directing heat upward.
Manifold Placement
Manifolds distribute hot water evenly through the tubing. Place them centrally to minimize pipe runs and pressure drops.
Thermostat & Zoning
Use smart thermostats for precise temperature control. Zoning allows different areas to be heated independently, improving efficiency.
Maintenance & Efficiency
Annual Inspections
Check for leaks, air pockets, and pump performance. Flushing the system every few years removes sediment buildup.
Energy Efficiency
Pairing hydronic heating with a high-efficiency boiler or heat pump reduces energy costs. Low-temperature systems (under 120°F) maximize efficiency.
Final Thoughts
Choosing a reputable brand like Uponor, Rehau, or Viega ensures a reliable hydronic heating system. Proper installation and maintenance keep your floors warm for decades. For more insights on heating solutions, explore our guide on hot water baseboard heaters.
