Fireplace Grates
Our patented fireplace grates use thermodynamic principles to maximize heat output. The adjustable-arm design creates a radiant cavity that directs 5 kW of heat into rooms. Tested over 40+ years, these heavy-duty steel grates reduce wood consumption while maintaining easy fire-starting with newspaper alone. Customers report heating efficiency improvements of 70-90% compared to traditional grates.
Custom Grates
Custom fireplace grates accommodate unique fireplace dimensions and log sizes up to 9" diameter. Optional finials and pedestal bases enhance aesthetic appeal while maintaining scientific efficiency. Designed for both modern and historic fireplaces, these grates combine functionality with decorative elements. Customers with irregular fireplaces report achieving optimal heat distribution through customized configurations.
Outdoor Fireplace Grates
Outdoor fireplace grates optimize heat radiation for open-air environments. The design maintains structural integrity in exposed conditions while creating concentrated heat zones. Users report transforming outdoor fire pits into usable winter entertainment spaces. The steel construction withstands temperature fluctuations and weather exposure without compromising efficiency.
Extra Heavy Duty Grates
Heavy-duty grates feature reinforced steel construction for frequent or continuous use. Engineered for commercial settings or heavy residential usage, these grates maintain structural integrity through daily fire cycles. Customers using fires 5-7 nights weekly report 25+ year lifespans. The design prevents warping from sustained high temperatures.
Andirons
Add-on andirons combine functional fire support with decorative appeal. The pedestal design elevates logs for optimal airflow while creating elegant visual lines. Available as finial upgrades, these components enhance traditional fireplace aesthetics without sacrificing efficiency. Users report improved ember retention and consistent burn patterns with andiron-equipped grates.
People
Dr. Lawrence Cranberg
Inventor
Physicist Dr. Lawrence Cranberg developed the Texas FireFrame grate in 1974 using thermodynamic principles. A Harvard-educated Manhattan Project veteran, he held multiple patents and received global recognition for revolutionizing fireplace efficiency. His invention remains the only scientifically validated fireplace grate design.
Questions
How does the Texas FireFrame grate improve fireplace efficiency?
The patented adjustable-arm design creates a radiant heat cavity that directs 5 kW of heat into rooms while reducing wood consumption by optimizing airflow and combustion efficiency.
Can I use unsplit logs with this grate?
Yes, the design accommodates unsplit logs up to 9" diameter, allowing easy fire-starting with newspaper alone while maintaining consistent heat output.
How long do these grates last?
Customers report 25-40 year lifespans with regular use, with some original 1970s models still in operation despite heavy usage patterns.
Is installation complicated?
No special installation required - simply place in fireplace. The self-contained design works with existing fireplace structures without modifications.
How does it compare to fireplace inserts?
Saves $4,000+ in installation costs while delivering comparable heat efficiency. The open design maintains traditional fireplace aesthetics without requiring venting modifications.
Is scientific validation available?
Yes, the design principles were published in the American Journal of Physics (1983) and validated through decades of peer-reviewed media coverage and customer testing.
