G-Class is all about making wood burning as clean, simple and easy as possible while eliminating your high heating bills. To accomplish this, the G-Class is packed with an impressive array of features which together deliver unmatched product value. You will love how easy the G-Class is to operate and how simple it is to maintain. You will love the smoke free combustion and be amazed at how much less wood you will burn when compared to older outdoor wood furnace technology. G-Class takes it to a whole new level. These products truly are in a class all there own in the outdoor furnace industry.
Description
Polar G-Class
All types of heat exchangers in wood furnaces coat with dust over time and need to be cleaned regularly to maintain optimal efficiency. So making the heat exchanger easy to clean is the third important component to creating a high efficiency outdoor wood furnace. The G-Class products include the EASY SWEEP SYSTEM which allows the heat exchanger to be cleaned daily in as little time as 5 seconds.Moving the external EASY SWEEP handle activates the rocker system which moves the spirals inside the vertical heat exchanger tubes up and down. This up and down sweeping action knocks accumulated dust from the vertical heat exchanger surfaces and the dust simply falls down through the heat exchanger tubes to the base of the furnace for monthly removal. The innovative patent pending design of the EASY SWEEP linkage system makes removal of the entire system for annual maintenance something that can be done in just a few minutes.
The harder the G-Class products work the more efficient they become and when tested with the appropriate EPA approved North American test method the G-Class achieves overall efficiency exceeding 86% for a category 4 burn. Reported efficiency varies a lot depending on the test method used. For example when using European test methods which use the lower heat value of wood for calculations the reported efficiencies can be as high as 95%.Regardless of how its calculated or what number is reported the G-Class products are remarkably more efficient compared to older outdoor furnace technology. When a conventional old style outdoor furnace is replaced by a G-Class furnace the saving on wood usage is as much as 60%!
A channel built into the top of the fire chamber and the powerful ECM suction fan work together to insure your comfort and safety during loading. When the fire chamber door is opened the suction fan pulls any smoke that would otherwise escape from the fire chamber back towards the chimney and away from you! A must have feature for indoor installation.
The Connect-EZ system includes a boiler recirculation pump, boiler protection valve and manifold and is installed into the plumbing compartment at the rear of the furnace. This patent pending system greatly reduces installation cost, simplifies the installation and has multiple ports for easily connecting more than one primary distribution loop and pumps.
The Ignition Door gives direct access to the bottom of the firebox which is really nice for a number of reasons.
- The Ignition Door allows you to set the wood on fire AFTER filling the entire fire chamber with wood. Also, while lighting the fire the suction fan creates strong negative pressure inside the fire chamber which keeps any smoke from escaping as air is sucked in through the door opening.
- Lighting the fire is also very easy because air flows precisely to where you are trying to set the fire. You will be amazed how easy it is to light a fire inside the G-Class.
- The Ignition Door gives direct access to the very bottom of the fire chamber for stirring the coals and ashes prior toreloading as well as for easy direct access for removing bulk ash that accumulates over time. The suction keeps escaping fine dust and ash to a minimum while completing these tasks.
Resin bonded glass fiber board insulation with a foil layer retains not only radiant heat but also infrared heat energy for superior insulating performance. This type of board insulation is the best choice for outdoor furnaces because it is rigid and does not sag over time and does not trap or retain moisture.
