Zero Clearance Fireplace

A Zero Clearance Fireplace typically refers to a fireplace that was designed so that it can sit right next to the framing. To do this the fireplace must contain and control the heat so that the surface temperature of the fireplace exterior sitting next to the framing remains cool and does not create any chance of a fire hazard.

The quality and efficiency of different zero clearance fireplaces varies widely.  EPA Certified fireplaces are going to be the most efficient and include features such as outside air sources sufficient to satisfy all combustion air needs, controllers for the combustion air intake that allow the heat ouput and burn time to be controlled by the home owner and glass doors that are gasketed or sealed.

The lesser zero clearance fireplaces will have either none or only some of these features.  The very poorest will actually pull more air out of the house than they give back in heat so the net effect will be to make it colder rather than warmer.

Wood Burning Insert

A wood burning insert for your fireplace with advanced combustion technology will usually cost between $1500 and $2500, with installation.  If you are purchasing a new home and want to add a fireplace, this is a great opportunity to choose an advanced combustion fireplace.  If your existing home already has a conventional fireplace, you should seriously consider retrofitting it with a new wood burning insert to save on energy costs, ensure comfort and safety.

In this case, look for an advanced combustion insert that is especially designed to be inserted into an existing fireplace. Along with the new wood burning insert it is likely that you will need to put a liner in your existing chimney to make it compatible with the new technology. Use an approved stainless steel chimney liner to prevent condensation of combustion products and to ensure a good draft.

A new installation should use one of the high-temperature chimneys that are designed specifically for wood burning appliances. These metal chimneys are specifically designed to withstand continuous gas temperatures up to 1200o F, which is higher than chimneys intended for other fuels. This type of chimney also has a thicker wall, additional insulation and a higher grade inner liner than other chimneys.

The design and manufacture of energy-efficient wood burning inserts is an ongoing process. Work continues on the creation of systems that are energy-efficient, environmentally friendly and safe to operate.  Over time, the introduction of government regulations and standards for wood burning fireplaces and wood burning stoves could make the use of advanced combustion fireplaces mandatory.

Pellet Fireplaces Becoming More Convenient

Wood pellet fireplaces are becoming a more populare option for reducing utility costs as heating fuel prices continue to soar.

The wood pellets that are used to fuel these pellet fireplaces are made from wood scraps that are compressed into pellets to form a smooth flowing and even burning fuel. Although they are typically a less expensive way to heat they are a bit less convenient than just turning up the thermostat to the furnace.

The pellets typically come packaged in 40-50 pound bags. They can be bought in small numbers or delivered by the pallet.  Each day the pellet fireplace is in use it has to be reloaded.  With heavy usage it may require a second refill.

But according to Peter Howe of NECN, Jon Strimling had a better idea.  His idea was for homeowners to be able to flick a switch and have a hopper load the pellet fireplaces and then have a delivery truck load the hopper.

“We’re taking pellets in bulk out of the back of this truck, by bulk I mean there’s no bags in them, and we’re flowing them down this pipe into the garage” says Strimling.

The typical home using 3-4 tons a year would only require two fills to keep their pellet fireplace running. That’s 3-4 tons that the homeowner doesn’t have to move by hand.

Strimling’s company currently charges around $325/ton, with the bags being delivered on pallets. In heating value, that is 30-40% less expensive than heating oil. They have just begun selling hopper systems and hope it will make pellets even more popular.

Ten to fifteen percent of the product cost is actually tied up in the packaging, so bulk delivery of the pellets is not only less hassle, it costs about 10 percent less as an added bonus.

Despite the hands on requirements of heating with pellets, it’s popularity has grown in recent years. More then 800,000 U.S. households use pellets for either some or all of their heat.  This equates to 2.2 billion pounds of wood pellets annualy. The industry continues to grow with over 80 pellet producers and 23 manufacturers of pellet fireplaces, stoves, and pellet furnaces.

Wood Fireplace Insert

The advanced combustion technology used in a modern wood fireplace insert was developed as part of a serious effort by the U.S. and Canada to reduce emissions from wood stoves in order to satisfy environmental regulations. The main design elements of the wood stove technology are now being incorporated into new fireplaces, creating a safe, efficient and cost-effective alternative to conventional fireplaces. This new technology is also being made available in new wood fireplace inserts which can be installed into an existing fireplace.

These fireplace inserts use a sophisticated secondary combustion process that ensures more complete combustion of the wood and smoke.  This increases the fireplace’s operating efficiency and reduces the amount of emissions escaping from the firebox.

These advanced combustion fireplace inserts use two separate preheated paths of combustion air. One air source feeds directly into the burning wood.  The second is aimed above the main fire in order to capture and ignite the incomplete combustion gases that would otherwise be released up the chimney. This results in two simultaneous combustion zones and flame patterns.

Modern wood fireplace inserts using advanced combustion technology have airtight, gasketed doors, a special ceramic glass window that allows much of the infrared heat to be transmitted to the room, and a hot air blower “sweeping” the window to allow easy viewing of the fire. When a fireplace insert is installed with the back against an exterior wall, some type of insulated outer casing that prevents unwanted heat loss from escaping should be installed.

These advanced combustion units have better heat exchange properties than conventional fireplaces because room air is drawn in through a grille under the firebox where a fan sends it through a heat exchanger and back into the room through grilles at the top of the fireplace.  With some units, the heat can also be ducted to adjacent rooms where an auxiliary fan can send it through ducts to the rest of the house.

The air requirements for these new fireplaces are very low requiring as little as one tenth of the ventilation of a typical house. It is, however, still a good idea to supply the fireplace with direct outside air for combustion (this is mandatory in some areas).

Another benefit of an advanced combustion wood fireplace insert is that they have little or no interaction with the house air, so the chances of combustion products leaking into the home are minimal.  They also enhance the safety and effectiveness of supplying outdoor air directly to the fireplace. The maze that is used for preheating the air before it goes into the firebox is designed to keep the combustion gases from escaping.

Real Energy Efficiency

Advanced combustion fireplace inserts offer levels of energy efficiency as high as 50 to 70% (even higher when installed in a major living area with an open view to other parts of the house).  This can reduce overall energy demand and dramatically lower heating bills.  This is especially true for homes currently heated by electric baseboards.

Impressive Environmental Benefits

The use of two separate combustion zones reduces emissions by ten fold compared to a conventional fireplace. This enables the environmentally friendly use of wood, which is a renewable energy source. Low levels of creosote and incomplete combustion products virtually eliminate the potential for chimney fires as an added benefit.

Emergency Preparedness

In case of an electrical power failure, new wood fireplace inserts can still operate as emergency heat source for the house. Even though the electrical circulating fan will not operate, the heat from the fire will radiate from the fireplace into the house by natural convection, supplying a significant amount of heat to the home.

Creative Recycling For The Fireplace

How can you use left-over cooking oil, toilet paper rolls, and dryer lint to make your life easier.  Well, believe it or not, there is a valuable use for these items and it not only recycles them and keep them out of the waste cycle, but it also makes your life easier as well.  This is a pretty neat idea for a recycling, self-sufficiency geek like me.

Sue Talbert of annarbor.com recenty wrote an article about creating her own easy to use fire-starters by using items in the home that she would normally throw away any way.  It is a highly creative use and a great idea for making your fireplace easier to use and making use of items you already have on hand and reducing the amount of waste that your household put out.

The full article is here.

I love this idea for the fact that it not only makes use of normally wasted materials but it saves you from spending money on commercial fire-starters as well. A double win!

If you have any great ideas like this feel free to pass them along.

Fireplace Economics and Efficiency

In many homes, the fireplace is the heart of the house, and when you add a wood fireplace insert, it can also bring you many hours of economic comfort and environmentally friendly warmth?  Wood fireplace inserts are a type of stove that is specifically designed to fit into the firebox of an existing fireplace so that they can use the fireplace flue as the vent.

Why invest in a wood fireplace insert you ask?

Well, a wood fireplace insert will transform a 10% efficient fireplace into a 70-80% efficient wood heater overnight.  Now that’s a major boost in efficiency!  In fact, many air-tight fireplace inserts allow one load of wood to heat a home all night long.  Because of this the insert will end up paying for itself.  Fireplace inserts can achieve sizable payback in 2-3 years just from the money saved on heating bills.  The colder your climate the faster the payback.  Fireplace inserts also eliminate the normal cold air drafts down the chimney as they provide both radiant and convection heat that distributes heat more evenly throughout the entire room.

If you have a gas equipped fireplace, gas-fired inserts are also available. Gas fireplace inserts have a greater output of heat than conventional gas logs and they are designed to be more like a wood-burning insert. Gas inserts provide convenient heat that’s clean, easy to use and safe for the whole family to use. All you have to do is turn it on and sit back and enjoy the fire and warmth.

When installing a new hearth appliance be sure to have your chimney and venting systems inspected by a Certified Chimney Sweep before the installation process begins.

Tax Credit For Efficient Inserts

Here is a recent press release that has some interesting information about using government incentives to help cover the cost of installing a new, more efficient fireplace insert.

Tax Credit Allows Homeowners to Stay Warm and Save Cold Cash On Lennox Hearth Products

Up to $1,500 now available for purchase, installation of energy-efficient wood and pellet Stoves, fireplaces or fireplace inserts

Orange, CA (Vocus/PRWEB ) February 2, 2010 — Providing taxpayers with incentives to make homes more energy efficient is a key portion of the American Recovery and Reinvestment Act of 2009, and the federal government recently issued clarifying guidelines on how the legislation affects homeowners who purchase a 75 percent efficient wood- or pellet-burning stove, fireplace or fireplace insert. When homeowners purchase and install qualifying hearth products during 2009 and/or 2010, including many from Lennox Hearth products, they can receive a 30 percent tax credit for costs incurred, up to $1,500.

Energy efficiency is a key component of the Stimulus Plan, as it provides incentives to homeowners who purchase high-efficiency, alternative energy heating sources such as wood or pellet stoves and fireplace inserts. These products provide potential energy savings to the American homeowners while also benefiting the environment

The fireplaces, stoves and inserts available today are definitely not your grandpa’s wood stove
When you add the tax credit on top of cleaner emissions, increased efficiency, the opportunity to zone heat your home and the desirability of using renewable fuels to reduce your carbon footprint, it just makes good sense for homeowners to consider the benefits of investing in a wood or pellet heating products

“Energy efficiency is a key component of the Stimulus Plan, as it provides incentives to homeowners who purchase high-efficiency, alternative energy heating sources such as wood or pellet stoves and fireplace inserts. These products provide potential energy savings to the American homeowners while also benefiting the environment,” said Wendy Howells, vice president and general manager of Lennox Hearth Products (LHP). “Wood- and pellet-burning stoves, fireplaces and inserts are cost effective and can help homeowners utilize zone heating to further save on their home-heating costs. A good example of zone heating is when a stove is used to heat the kitchen and great room during the day. Then rooms such as formal living rooms, dinning rooms and bedrooms, which families use less frequently during that time, can be maintained at lower temperatures, saving money.”

Wood and pellet stoves offer additional environmental benefits as a home-heating option since the fuel sources they use are renewable, as opposed to natural gas, oil, propane or electricity. The new legislation means homeowners who are dedicated to living in a way that reduces their environmental impact are now being rewarded with a significant tax credit to help their efforts.

“The fireplaces, stoves and inserts available today are definitely not your grandpa’s wood stove,” said Howells. “Lennox Hearth Products has more than 20 different models that qualify for the tax credit and they complement virtually any home interior, from traditional to contemporary to rustic.

“When you add the tax credit on top of cleaner emissions, increased efficiency, the opportunity to zone heat your home and the desirability of using renewable fuels to reduce your carbon footprint, it just makes good sense for homeowners to consider the benefits of investing in a wood or pellet heating products,” added Howells.

An Official Manufacturer’s Certificate, which homeowners can use when preparing tax returns, is available to customers at www.lennoxhearthproducts.com. While neither the certificate nor a product sales receipt is required for submission to the government, homeowners are encouraged to retain both for their tax records.

Fireplace Inserts; Your Backup Heat Source

With the recent major winter storms that have hit the east coast it reminds us how beneficial it can be to have a wood fireplace insert and a good supply of fuel that can provide heat for the home and for cooking at times when conventional power sources fail us.

Heavy winter storms are always a possibility in many areas and having an alternative heating source like a wood burning fireplace insert or a wood stove just makes good sense.  A good emergency plan will always provide the capability of being self-sufficient for a least a few days by having sufficient supplies on hand and having alternative heat sources.

If you live in an area where the weather can become extreme and you don’t have your own independant way of producing heat you really need to take the time to find a solution that will work well for your budget, lifestyle and amount of risk.   If you live off in a rural area and the power goes out, it may take quite some time for help to arrive in the worst of cases so you need to have a plan in place now.  Take some time and make sure your are prepared now while you are thinking about it – not when it is too late.

What Are Wood Fireplace Pellets?

Wood fireplace pellets are small pellets made of compressed wood chips and saw dust that is a by product of other more lucrative wood processing. The chips and saw dust are dried to a specified moisture content, then compressed by a very high pressure machine. They are compressed with so much pressure that no binding agent is required other than the sap from the timber itself.

The benefits of wood pellets are as follows:

- Ease of transport

- Clean burning fuel

- It complies to consistent standards. (Things which have standard sizes, shaped and moisture content can easily be designed for)

Pellets can be purchase by the bag for hand loading or by the truckload if you have a system that is set up for it.

When ordered by truckload the pellets are blown from a delivery truck up to 20 yards to a storage unit. In the past there has been a lot of hassle with dust, but this was largely due to the use of agricultural feed trucks being used to deliver the pellets. As dust is not really an issue for agriculture, they did not have dust minimisation technology, and it was a mess. If you use one of the large suppliers these days, there is little problem.

Understanding Wood Pellet Boilers And.. Combustion

Wood pellets can also be used to fuel a boiler.  The pellets are fed into the “burner” where they are burned. The burner in all boilers does much the same job. It’s a place where the fuel is mixed with air to provide the optimal conditions for combustion, and lit. Before you know it the combustion gases are travelling through the heat exchanger where it heats up the water.

The flame from the burner, and the resultant combustion gases escape into the boiler, transferring their heat to the water circulating through the heat exchanger within the boiler. The heat is then distributed the house using a wet system. In most cases water flows through the heat exchanger in the boiler, absorbing heat from the flame and the combustion gases. This hot water is then circulated around the house to radiators, underfloor heaters and hot water cylinders.
