Harman VF3000 Stoker Boiler

Coal-Fired Comfort with High-Powered Performance

The Harman VF-3000 Stoker Boiler is a compact, high-performance hot water boiler with a wide range of output.

Whether you are heating 1,000 or 3,000 square feet, the VF-3000 will produce the temperature you desire. The 250-pound hopper supplies coal to the patented Verti-Flow feeder, where it is burned automatically and can be unattended for three to five days, depending on outside temperatures.

The VF-3000 was designed with the customer in mind. It is totally reversible so you can have the hopper and doors at the most convenient place. An external cleaning rod cleans all internal pipes and baffles. All controls and adjustments are easy to reach and adjust. A large ash tub holds all the ashes from the 250-pound hopper full of coal.

The VF-3000 can be broken down into two pieces for easier installation. The base is designed to keep the bottom of the unit four inches above the floor in case of a wet or damp basement. We also have a factory trained dealer network that would be happy to install a unit in your home.

The Aquastat helps keep your home's water at your desired temperature. The Aquastat tells the feeder/oil burner what temperature the water is, then adjusts the fire and feed rate in order to maintain your set temperature.
