Ultra-Fin is engineered to integrate seamlessly with all standard hydronic components — no proprietary fittings, no special boiler requirements, no new learning curve for your installation crew.
System Compatibility
Ultra-Fin was designed from the start to work with the tools, materials, and components already in the hands of every professional hydronic installer.
Full Technical Specifications
Use these specifications for design, submittal documentation, and installation verification. All values are for the Ultra-Fin standard residential panel system.
Fluid Compatibility
Aluminum is compatible with most hydronic fluids but requires attention to water chemistry to prevent galvanic corrosion and scaling. Follow these guidelines for long-term performance.
| Parameter | Required Range | Risk if Out of Range |
|---|---|---|
| pH | 7.0 – 9.5 | Corrosion below 7.0; scaling above 9.5 |
| Chloride Content | <25 ppm | Pitting corrosion above 25 ppm |
| Dissolved Oxygen | Minimal | Accelerated corrosion |
| Glycol Type | Propylene (inhibited) | Ethylene glycol: check inhibitor for Al |
| Glycol Concentration | Up to 50% | Performance reduction above 50% |
| Hardness | <150 ppm CaCO3 | Scaling at elevated temps |
| Inhibitors | Aluminum-compatible | Some HVAC inhibitors degrade aluminum |
Floor Covering Specifics
All finish floor materials can work with Ultra-Fin — but each has specific requirements. Use this table when advising owners and flooring subcontractors.
| Floor Covering | Compatible | Max Floor Temp | Design Note | Special Requirements |
|---|---|---|---|---|
| Solid Hardwood | Yes | 85°F (29°C) | Design system for self-limiting operation | 22°C home temp, 6–12% MC before install |
| Engineered Hardwood | Yes | Varies by product | Check manufacturer's radiant approval | Acclimate per manufacturer spec |
| Ceramic / Porcelain Tile | Yes | Unlimited | Excellent conductor — efficient output | Flexible thinset recommended |
| Natural Stone / Slate | Yes | Unlimited | Good conductor; design for stone R-value | Flexible thinset; grout compatible with heat |
| Luxury Vinyl Plank | Yes | 80–85°F (verify) | Check manufacturer's max temp rating | Floating install; allow for expansion |
| Laminate | Yes | 80–85°F (verify) | Check mfr. radiant approval and temp limit | Floating install only; no glue |
| Carpet & Carpet Tile | Yes (with design) | 85°F | Account for carpet R-value in loop design | Use pad with R < 0.5 for best results |
| Cork | Conditional | Check mfr. | Natural cork can dry out — check approval | Verify with flooring manufacturer |
| Bamboo | Conditional | Check mfr. | Varies significantly by product and binder | Verify with flooring manufacturer |
