The Harman Magnum Stoker is a serious coal stove for people who want long, steady heat with very little fuss. Using anthracite rice coal and Harman’s Verti-Flow stoker system, the Magnum can deliver roughly 5,000 to 85,000 BTUs of output, giving you everything from a gentle background heat to a powerful whole-house heater, depending on your home and climate. A deep coal bed and thermostat-controlled feed let the stove “idle” at low heat in mild weather, then ramp up automatically when the temperature drops.
A 100 lb hopper and efficient combustion system mean long burn times and fewer trips to the stove. The heavy welded steel body, large ash pan, easy-clean heat exchanger, and simple access to grates and internals make the Magnum Stoker a favorite with coal burners who want durability and straightforward maintenance. Many stoves have been in service for decades with only routine care and periodic part replacements.
At Harman-Parts.com, we help keep Magnum Stoker coal stoves running safely and efficiently year after year. We stock the most common replacement parts for the Harman Magnum Stoker, including:
- Stoker motors and feeder components (for feed issues or inconsistent burn)
- Ignition and control components
- Convection and combustion blowers
- Grates, grate inserts, and firebrick
- Door, glass, and hopper gaskets to restore a tight seal
- Glass panels, knobs, and cosmetic hardware
Because Magnum Stokers have been produced over a long period and may have small variations, it’s easy to get unsure about part compatibility. If you’re not certain which replacement you need, be it the auger motor, blowers, or gaskets: contact us with your stove’s model information (and a photo if possible). We’ll help you identify the correct Magnum Stoker parts before you order.
Additionally, check out our Magnum Stoker Troubleshooting Guide to help narrow down the root cause of any issues your stove is having.
