The Empyre Pro Series is leading the way in new high efficiency clean burning technology. For you, this efficiency means savings all around. The Pro Series burns cordwood, a renewable resource and easily accessible in many areas; the Pro Series requires no splitting of wood. Although the firebox is smaller and requires less wood, it maintains burn times comparable to conventional outdoor furnaces at the same output, leaving you with less work and more time. Clean burning also means that the furnace does most of the work. Constant ash cleanup is obsolete with the Pro Series. Although ash is minimal, the Pro Series built-in cleaning portals make sweeping out fly ash from the fire chamber and flues a quick and simple task. The high heat of the gasification process also eliminates creosote buildup in the chimney and reduces moisture in the unit, preventing rust.


How It Works

The Empyre Pro Series combines the simplicity and safety of a conventional furnace with the savings and technology of a high efficiency furnace to provide heat for your house, greenhouse, pool, shop, or other buildings.

Heat from the Pro Series dual burn chamber is transferred to the furnace’s built-in water reservoir through a series of flues. This heated water is then channelled to your home’s heating system through underground insulated pipes. The Pro Series` full length back door makes plumbing simple.

In a house, the heated water connects directly to the radiant or forced air heating system through a heat exchanger. Similarly, the Pro Series heats all domestic hot water through a sidearm heat exchanger installed on the hot water tank.


Inside the Pro Series

Digital Control Panel
The Pro Series features a digital control panel which allows the operator to regulate the furnace’s heat output.

Float Ball
By popular demand, the Pro Series also features the proven Empyre float ball water level indicator.

The Pro Series` pressure sealed locking door keeps the heat in the furnace and prevents unauthorized access.

Exhaust Curtain
The built-in exhaust exit and smoke curtain allows the smoke to escape through the top flues instead of out the door when loading the furnace.

The Pro Series meets CSA/UL safety standards and EPA Phase I and Phase II emissions standards.



The Empyre Pro Series Hot Water Furnace is ideal for a variety of applications. It can be used for a single building or residence or piped to other areas. The diagrams below show just a few of the possible applications. Contact a dealer near you for information on setting up an Empyre to meet your needs.

Radiant In-Floor Heating
In-floor heating is the most efficient and comfortable heating option, as hot water flows through tubes in the floor of a house or building, providing consistent heat.  

Forced Air Systems
Heat can also be transferred from the Empyre through your existing forced air system. A water-to-air heat exchanger converts heat from the water into usable heat for your forced air system.

Domestic Hot Water, Pools, and Hot Tubs
In addition to heating houses and other buildings, the Empyre Hot Water Furnace also provides heat for all domestic hot water. Generally a side arm heat exchanger unit is installed to your hot water tank. Similarly, the Empyre can provide heat for pools and hot tubs through a water-to-water heat exchanger installed on the pool heater.

Other Buildings
Other applications, such as greenhouses, shops, sheds, and other outbuildings use similar hookup methods, and in most cases, a single Empyre unit can provide heat for several buildings.
