Benefits of Copper & Cast Iron
The Mini-Therm JX has a unique, field-proven heat exchanger design that intelligently combines finned copper tubing with cast iron "wet walls" to create a perfect balance of quck heat transfer and stored heat.
Copper transfers heat up to 7x faster than cast iron for a faster heating response
Cast iron wet walls store excess heat to minimize short cycling - increasing efficiency and heat exchanger life
Mini-Therm JX is smaller and lighter than traditional cast iron boilers making installation and maintenance much easier
Low Loss Header System
Maintains the correct temperature rise (Delta-T) across the heat exchanger - offering improved performance and longer heat exchanger life
Protects the heat exchanger from low return water temperatures (Economy Mode or Outdoor Reset)
System pump interrupt for anit-condensing feature
Allows for direct replacement of traditionally piped cast iron boilers
Reduces installation time resulting in savings
