Cast Iron Wood Burner with Back Boiler: Your Trusted Source for Efficient Hydronic Heating
If you're sourcing a cast iron wood burner with back boiler for off-grid, rural, or heating‑conscious projects, you need a partner who delivers consistent quality, timely shipments, and compliance with US safety standards. Shijiazhuang TJJ TRADE CO.,LTD., backed by over 20 years of foundry expertise, offers robust, customizable wood burners engineered for maximum heat transfer and durability. Whether you're a wholesaler, brand owner, or sourcing agent, this page explains how our factory‑direct supply chain, strict quality control, and flexible OEM/ODM services meet your procurement needs.
Industry Pain Points & Solutions
Many import managers face recurring problems when sourcing cast iron heating appliances: inconsistent metal quality, incomplete certification documentation, long lead times, and minimal customization support. These issues delay market entry and erode end‑user trust.
Our solution: TJJ operates a dedicated foundry with ISO‑managed processes (ISO 9001 compliance – details as per order confirmation), experienced metallurgists, and a dedicated export team. We produce cast iron wood burners with back boilers that meet ASTM, UL 1482, and relevant CSA standards. Every unit is pressure‑tested for back boiler integrity, ensuring safe, efficient hydronic heating for radiators or underfloor systems.
Product & Service Advantages
1. Superior Cast Iron Construction
Our wood burners use high‑grade gray iron (ASTM A48 Class 35B) with precise section thickness to retain heat and resist cracking. The back boiler is integrated during casting, minimizing leak points. Standard output ranges from 12 kW to 25 kW (40,000–85,000 BTU/h), suitable for small homes to large workshops.
2. OEM/ODM Flexibility
We design and manufacture according to your specifications: flue diameter, boiler placement, door style, paint color (heat‑resistant stovepaint), and even custom nameplate. MOQ is low (as per negotiation) to support market testing.
3. Fast, Reliable Delivery
With a 20‑year foundry history and streamlined export logistics, we typically ship within 45–60 days after order confirmation. Volume orders may reduce lead time. FOB/CIF terms available; packaging includes reinforced plywood crates or poly‑wood frames with IPPC heat‑treatment.
4. Compliance & Certification Support
We assist with certification paperwork for the target market. Our cast iron composition is RoHS‑compliant; burners can be manufactured to meet UL or EPA test requirements (actual certifications depend on order specifics). Third‑party inspection is welcome.

Our Clients Speak
Mark Thompson – Import Manager, Northeast Heating Supply, USA
"We tested three Chinese foundries before TJJ. Their cast iron wood burners with back boiler met our UL requirements and the boiler pressure test was perfect. Lead time was exactly as quoted – 52 days. We've placed four repeat orders."
Sophie Laurent – Brand Owner, EcoHeat Stoves, Canada
"OEM customization was easy – TJJ modified the door design and boiler port for our radial heating system. The quality rivals European stoves at a much better price. Their after‑sales team is responsive."
James Caldwell – Sourcing Agent, Archipro Inc., Australia
"I've sourced cast iron products from Asia for 8 years. TJJ's foundry is one of the most professional I've seen. Their wood burners with back boiler are well‑engineered, and the packaging survived ocean freight with zero damage. Highly recommended."
