Model 710 Energy Master II Stoker Furnace

HITZER’S ENERGY MASTER II Model 710 stoker hot air furnace is one of the most efficient and technologically advanced stoker furnaces on the market today.  Its 160 pound stainless steel hopper and large ash pan provide long unattended burn times. The ENERGY MASTER has the ability to be operated with a power vent as well as a chimney. This makes it usable where there’s no chimney and no way to install one.  

With its integrated Coal-Trol Digital ™ control system you have precise push button temperature control of the 7,000 to 150,000 BTU burner and 1008 CFM distribution blower for constant even heat. It boasts one of the most precisely controlled heat outputs on the market today.  This precise control saves coal by not burning more than needed to hold the set temperature. It also has a day/night set back saving more fuel by holding a lower temperature overnight than during the day  The Coal-Trol Digital ™ control constantly monitors room temperature and adjusts the fuel feed rate to maintain the set temperature. Also as the feed rate is adjusted up and down the convection blower speed, blowing the heat into the room, is adjusted up and down. The catch phrase for this control is “Cruise Control for Your Coal Stove” meaning you have constant control of your feed rate.

Can I use a small amount of coal if I just want a small fire?

The important factor is the whole grate area must be covered in order for the Anthracite Coal to burn properly. Also a deep bed of coal burns better than a shallow bed. This doesn’t mean the whole bed of coal will ignite, because coal burns from the bottom up. Therefore, it will only burn the bottom layers even if there is a deep bed of coal. Your coal will not burn if the whole grate area is not covered because the air flow will go around the coal instead of through the coal.

How do I make my stove burn warmer?

There are numerous ways to make the stove burn warmer. First, remove all the ash build up by shaking the ashes with the grate shaker. Next, allow for more air to enter through the air intakes. This can be done by adjusting the thermostat to a higher number, opening the ash door slides, opening the air intake knobs, or a combination of these methods. The last method is to apply more fuel, as you might not have enough fuel to maintain a hot fire.

How do I start Anthracite Coal?

Anthracite Coal starts differently compared to other fuel sources. There are three important factors that must occur to start Anthracite Coal successfully. The three factors are air flow, heat source, and fuel. First, there must be air flow and the air must come from the bottom and flow up through the coal. The next necessity is that there must be an already hot source of heat such as a kindling fire or hot charcoal. The last necessity is that there has to be enough Anthracite Coal to burn properly. This system of events occurs over a period of time and must be performed in stages. The first stage is to clear all of the ash to allow correct air flow. The next stage is to create a hot kindling or charcoal fire. And finally, the last stage is to cover the whole grate area one layer at a time with coal, allowing each layer to start burning before applying the next layer.

How many BTU’s are in Anthracite Coal?

There are around 13,500 BTU per pound of Anthracite Coal.

How much ash do I shake out when shaking my ashes to my ash pan?

It is important to shake enough ashes to allow the proper amount of air flow up through the coal. It is important when shaking the grates with the grate shaker to use fast, short, vigorous strokes; this rocks the grates back and forth without losing all of your hot coals. Continue this method until red coals fall into the ash pan. When there are red coals that fall into the ash pan roughly the length of the grate, the proper amount of ash has been removed.

How tall should my chimney be to have good draft?

The chimney should be 2 feet taller than anything within a 10 foot radius. In most situations the taller the chimney the better draft it will have.

Is Anthracite Coal the same as Bituminous Coal?

Anthracite coal and Bituminous coal are very different. 

Anthracite Coal is a premium type of coal. It is very hard and compact. It is considered the highest quality of coal. It has the least amount of impurities, giving it the name “Clean Coal.” Anthracite coal has no soot residue and produces no smoke when consumed. 

Bituminous Coal is a “soft coal” that contains tar-like particles within the coal. It is dirty to touch as well as burn. Because of these tar-like particles called “bitumen” it leaves soot like residue. It also produces dark smoke full of impurities and bitumen when consumed.

Is there any creosote in Anthracite Coal?

No, there is no creosote in Anthracite Coal. Anthracite coal and wood are very different fuel sources. There is no soot or smoke when burning Anthracite coal.

What is Anthracite Coal?

Anthracite Coal is a premium hard clean-burning coal mined out of Pennsylvania. It is one of the most economical fuel and heat sources in the world today. Anthracite coal produces the lowest cost per BTU and more consistent even heat, compared to other fuel sources such as wood pellets, fuel oil, natural gas, electricity, and wood. Anthracite coal burns very warm and clean producing no dirty soot or particle build up. It leaves no residue and produces no smoke.
