Maximize Your Fireplace Heat-Output To Lower Fuel Bills
By: Susan Penney
For some people, a fireplace might as well be a video of flaming logs. Their primary interest is the welcoming ambiance a fireplace's blaze presents. If, however, you expect your fireplace to provide heat in exchange for your log-carrying, fire-building efforts, (or in the case of gas logs, in exchange for your gas bill), it's time to maximize your fireplace's heat output.

There are various contraptions designed to return more of a wood or gas fireplace's heat into the room and stanch the flow of that precious heat from escaping up the chimney. Many of them involve fans and vents and considerable expense. But one of the most time-honored, hassle-free, and least expensive methods of increasing a fire's heat output is making a comeback: the fireback.

A fireback is a sheet of metal, sized in proportion to the fireplace, that's placed against your back fireplace wall. Firebacks can be set on the hearth's floor and just leaned against the back fireplace wall, but often they are secured by placing them in supporting braces which keep ...
... the fireback from sliding. Firebacks come in two main styles: the cast iron fireback and the stainless steel fireback.

The traditional cast iron fireback, popular in earlier times and making a revival now, is a sheet of heavy, black, cast iron. Often they are cast with a design, such as a fleur de lis or eagle, to add a decorative touch to this functional fireplace accessory.

The cast iron firebacks work on the same principle as heating radiators. The metal is heated (by hot water in the case of radiators and by the fire in the case of firebacks), and then that heat is radiated into the room.

Although attractive and functional, the cast-iron firebacks are too heavy for many people to manage easily. Their weight also adds to their shipping costs, and therefore to their total price.

A more modern fireback design, one that is growing in popularity, is made of a sheet of very gently curved, tempered stainless steel. These stainless steel firebacks warm your room in two ways. First, like the cast iron firebacks, they radiate the heat of the fire forward into the room. But they also reflect the heat, as well as the light, of the fire into the room.

Stainless steel firebacks weigh only one-sixth as much as a similarly sized cast iron fireback, so they are easier to manage and less costly to ship. But their main appeal may be their price: They cost only a fraction as much as their cast iron cousins. Whereas a cast iron fireback, depending on size, can cost $250 to $700, the stainless steel versions usually go for $50 to $150.

Both cast iron and stainless steel firebacks dramatically increase the room-warming capacity of your wood or gas fireplace fire. The addition of this simple fireplace accessory to your hearth can mean warmer toes and lower heating bills.

Stainless steel resists corrosion, maintains it's strength at high temperatures and is easily maintained. For these reasons, it is used widely in items such as automotives, home and food processing products, as well as medical and health equipment. The most common types are: 304; 316; 316Ti; 316L; 29-4C.

316TI Stainless Steel
316TI is a stainless steel alloy with a small amount of titanium added. It's make-up allows it to resist acids and the stresses of hot and cold cycles. It can be used with solid fuels (wood, coal and pellet), gas and oil. It can withstand temperatures up to 2100 degrees.

316L Stainless Steel
316L chimney liner metal is commonly found in some thicker flexible chimney liners as well as in rigid chimney liners. The titanium is left out because of the added thickness of liners made from 316L stainless steel. 316L stainless steel is acceptable for use with coal, wood, gas or oil systems.

304L Stainless Steel
304L is best for chimneys venting a wood burning appliance. This alloy is commonly found in rigid chimney liner.

The most commonly specified austenitic (chromium-nickel-stainless class), it accounts for more than half of the stainless steel produced in the world. This grade withstands ordinary corrosion in architecture, is durable in typical food processing environments and resists most chemicals.

Al 29-4C Stainless Steel
This chimney liner metal alloy is used most often when relining a masonry chimney or clay lined chimney that will vent a modern high efficiency gas or oil furnace.

It is an alloy of stainless steel that is highly resistant to corrosion. It is used for relining flues where flue gases may contain highly corrosive elements. Being that most of the heat generated by such a high efficiency appliance goes into the home, the flue gas temperatures tend to be relatively low.

Low flue gas temperature keeps moisture in the flue gases from evaporating and being eliminated up the flue. The combination of moisture in the flue gas along with other chemicals that may be inducted into the flue from the surrounding environment, such as those from chemical cleaners and laundry supplies, can contribute to a very corrosive flue gas composition.
AL29-4C is made to resist such corrosive environments over a long period of time.
