7 Tips For Buying An Outdoor Fireplace

Posted by admin on Aug 7th, 2009 in Home | 0 comments

Before buying an outdoor fireplace, there are several factors to take into account. Always remember that the safety of your family and property is the most important consideration.

1. Size matters

When comparing fireplaces, look at the size of the fire area before the height. If the firebox is small, wood buying and cutting is more difficult.

Requesting for specially cut wood from your supplier increases your cost.

Try to find a large firebox, don’t bother with the tall and thin fireplace. A small firebowl will cost more down the road. You don’t need a large fire just because you have a large fireplace, just use less wood to have a smaller fire.

A good fireplace burns more cleanly and more efficiently than a firepit design having no smoke stack. The fireplace draws air into the fire and blows out the neck for an efficient burn. Firepit designs tend to smoke and smolder much more than a traditional fireplace design because of poor airflow.

2. Proper maintenance

Fireplaces made in the more commercial copper, clay or sheet steel don’t have the longevity or safety of aluminum or cast iron. Sheet metal fireplaces are available at a bargain cost. They’re pretty much a disposable type of fireplace. Once metal sheet fireplaces start to rust, they have already outlived their usefulness. Check the gauge or thickness of the metal. A metal too thin might melt.

Some cast iron fireplaces have sheet metal necks. If that’s the case, check if the manufacturer has replacement parts available and cost. Frequent replacement for the neck is not what you want.

Cast iron must be maintained to prevent rust. It is a little difficult to maintain. But a well maintained cast iron fireplace will last you a long time. Also, consider the placement of your cast iron fireplace.

The cast iron fireplace tends to stain the surface it stands on.

An occasional paint job with a high temperature paint will slow down rusting. The cast iron is heavy and can stand a lot of abuse.

Copper looks great initially but after a couple of uses it tends to be green and rusty. Several companies put holes in the bottom of the firepits to drain ash and water out during rain. Firepits without holes will be filled with water when it rains.

Cast Aluminum is one of the best buys. It is easy to maintain and a long lifespan. An aluminum fireplace does not warp and only has a slightly lower melting temperature than cast iron. Cast aluminum does not rust. It is also considerably lighter than cast iron making it easier to move around.

3. Weigh it

When comparing fireplaces, check the weight. Most fireplaces are produced by weight, so they are bought by weight. Be sure that you’re comparing the same material, copper to copper or cast iron to cast iron.

4. Aluminum feature

Cast aluminum is by far a better choice for a novice outdoor enthusiast. The fireplace is easier to maintain and can be easily moved around. It may be brought to a home by the lake or stored during winter along Northern areas. Store it to prevent damage or possible theft.

5. Clay fireplace

The most disturbing problem with a clay fireplace is that it can fall apart without prior warning. When the bottom falls out, it can be quite a mess. Avoid placing your clay fireplace on a wooden deck or any surface that can easily be damaged by heat or fire. Place it on cement or tile.

If you choose to purchase a clay fireplace, take safety precautions. Use a spark arrestor and a mouthscreen for safety. The extra cost is well worth it. A clay fireplace is generally cheaper but has a shorter lifespan than either aluminum or cast iron.

6. Surround view fireplaces and raised firepits

Most surround view fireplaces are built with light materials. Surround view fireplaces are easy to tip over because of the light material used to make it. When it is tipped over, it will send ash and embers everywhere.

Safety is an issue with surround view fireplaces. Slight breezes might send embers and catch fire with flammable materials.

If you’re buying a raised firepit, be sure that it comes with a lid. Otherwise, ash will be spread all over your patio when it rains.

7. What to burn

Hardwood is by far the most popular fuel for outdoor fireplaces. Pinon wood has a pleasant pine scent when burning. It keeps the flame active and generates good heat. It also helps in keeping insects away. Other fuel sources are propane, gel inserts, manufactured firelogs and natural gas.

Pine cones and applewood can be added for more aroma.

Several fireplaces come with inserts for natural gas and propane.

A Better Refrigerant For Air Conditioners And The Environment

Posted by admin on Aug 2nd, 2009 in Home | 0 comments

Most air-conditioners and heat pumps sold around the world use a refrigerant called R-22. Emissions of R-22 are considered by some experts to be a significant factor in depleting the ozone layer that protects animals and people from harmful rays from the sun.

Families now have the choice to ask for an air-conditioner or heat pump that uses a more efficient and environmentally friendlier refrigerant called 410A or R-410 when buying a new system for their home.

It’s Environmentally Friendlier. If your system ever leaks, the escaping refrigerant won’t contribute to ozone depletion! Why can’t R-410A affect the ozone layer? R-410A is not a CFC or an HCFC. It is called an HFC, or hydrofluorocarbon, and is made of hydrogen, fluorine, and carbon atoms. Because it has no chlorine, it won’t interact with the ozone layer once it breaks down.

You avoid the risk that R-22 could become expensive or difficult to get when your system needs to be repaired in a few years. The old refrigerant R-22 will be phased out along with other ozone depleting chemicals, and both supply and demand of this chemical will be significantly affected by current and upcoming regulations. By selecting an air conditioner or heat pump that uses R-410A, you will avoid the risk associated with purchasing a product that is destined to become obsolete.

R-410A systems can be more reliable than R-22 systems. R-410A air conditioning and heat pump are today’s “state of the art” systems, and utilize the most current technology available for efficient and reliable operation. The heart of every air conditioner or heat pump is the compressor, and newer systems are specifically designed to use R-410A refrigerant. R-410A can absorb and release heat more efficiently than R-22 ever could, compressors with R-410A run cooler than R-22 systems, reducing the risk of burnout due to overheating.

We all know that the first thing “to go” on an air conditioning unit is the compressor. All air-conditioning systems use an oil that circulates through the inside of the system to keep all of the parts well lubricated, just like the engine of your car. R-22 air conditioners use an oil known as “mineral oil” that has been used for decades. R-410A air conditioners use newer synthetic lubricants that are usually more soluble with the R-410A than the old mineral oils are with the older R-22 refrigerants. This means the synthetic lubricants and R-410A can mix and circulate more efficiently to keep the compressor and other moving parts lubricated, reducing wear and extending their life. Also, just as many new cars use synthetic oils because they are less likely to break down under high stress and heat, the new synthetic oils used in R-410A air conditioners are less likely to break down under extreme conditions.

R-410A offers some wonderful advantages, but it required the manufacturers of air conditioners to redesign their products to take advantage of the properties of the refrigerant. The reason why a refrigerant works is because it captures the heat from one place, and then releases the heat somewhere else. R-410A captures heat and then releases it better than R-22 did, so manufacturers have found that they need less refrigerant in an R-410A air conditioner than they needed in an R-22 air conditioner. Because there’s less refrigerant, they need less copper tubing, and often can use a smaller compressor. The bad news was that R-410A couldn’t be used in air conditioners that were made to use R-22, but the advantages for new air conditioners were too great to pass up.

It’s obvious that air conditioners manufactured for using R-410A are more efficient, more reliable, and may even be less costly then the older units that still use R-22. Compare the SEER or EER ratings and the ENERGY STAR rating to be sure.
