Geothermal vs. Solar

Friday, April 29th, 2011

If you are looking for a more environmentally friendly alternative to the traditional methods for home heating, you will probably consider both solar and geothermal options. Each of these relies on a great renewable resource to function and can be an excellent option depending on your specific circumstances. Of course, both geothermal and solar heating have limitations as well, so it is important to take these into account when you are evaluating your options.

A geothermal heating system works by extracting heat from the ground and transferring that to the air in your house. This occurs when heat is absorbed by a fluid flowing through a closed loop of pipes beneath or next to your home. The fluid then returns to your home, where the heat is extracted by a compressor and distributed throughout the house by an air handler.

This uses very little energy relative to a conventional heating system, as you only have to power the condenser and the air handler. The heat is not generated by the system but merely harvested, so total energy costs are quite low. However, the installation cost of a geothermal heating system can be many times what a conventional heating system would cost.

Solar heating relies on solar collectors to gather the heat from the sun. This heat is then passed into a system of heat pumps and heat exchangers so that it can be adequately distributed throughout your house. The installation of heat collectors, of course, is quite expensive as well, while the cost of running the system is generally low just as with the geothermal heat pump.

One advantage to opting for a solar heating system is that you can lease the equipment rather than buying it in some areas. This means that you do not have to pay the high installation costs and only pay a monthly fee to use the equipment which is usually comparable to what an average heating bill would be if you had a furnace.

But you also have to keep in mind that you need to have enough space to put up an adequate number of solar collectors to keep your house warm all winter. This often means giving up a lot of land, and if you have a lot, that is fine. But it is still something you need to take into consideration. Also, you need to make sure that the area you live in gets enough direct sunlight to make solar heating a viable option. Otherwise, you will be paying to run a backup system much of the time anyway.

Why Install a Ductless Air Conditioner?

Wednesday, April 27th, 2011

As you explore your options in terms of a new home air conditioning system, you will probably have to decide whether you want a system that uses ducts to get the cooled air around the house or one that is considered ductless. Each type of air conditioning system is appropriate in certain situations, so it is important to understand the benefits of each before you can make a decision.

Duct air conditioning systems are the more traditional type on the market today. They generally consist of an outdoor compressor and condenser unit and an indoor air handler. The outdoor unit passes the cooled air through ducts to the air handler, which then takes over circulating the air through the house and back out to the condenser again.

It makes sense to install this type of air conditioning system if you have a large house or if you have ducts already in place. Duct air conditioners can cool a moderate to large sized house quite effectively and they can also be coupled with zone control systems to give you multiple climate zones within your house.

Ductless air conditioners, as their name suggests, do not rely on a system of air ducts to get cooled air distributed throughout your house. Instead, these types of systems use refrigerant lines to transfer coolant from the outdoor compressor to the indoor, wall mounted units. Each of these indoor units can take care of cooling one or two rooms, but in order to cool an entire house with one of these systems, you will need to install multiple indoor units.

However, these multiple indoor units can all be connected to the same outdoor compressor, and they can also be controlled independently. That gives you much greater control over which parts of your house are cooled and how much energy you are using to cool areas that may or may not be occupied.

Ductless air conditioners are generally more energy efficient than ducted ones, but their real advantage comes from the facts that they can be installed even in places where air ducts do not exist or cannot go. If you do not already have ductwork in your house, installing a duct system will add considerably to the price of installing a ducted air conditioning system. In a case like this, a ductless system is much easier and cheaper to install and certainly makes more sense.

Why Select a Two Stage AC vs. Single Stage Air Conditioner

Monday, April 25th, 2011

When you are in the market for a new air conditioner, one of the decisions you will have to make is whether you want a two stage system or one that only functions in a single stage. Of course, before you can make a decision about this, you need to know what all of this means.

A single stage air conditioning system is probably what you are most familiar with. They have been around for longer and can be found in a wide variety of locations. Single stage air conditioners come on at full capacity when the temperature in your home rises above the preset level on the thermostat. Once they have effectively cooled the house, these types of air conditioners shut off until the temperature works its way back up again.

Two stage air conditioners, on the other hand, can function at either 67% or 100% of capacity depending on exactly how warm it is in your home. What that really means is that if the temperature in your home is only a little above the thermostat’s preset limit, the air conditioning system will come on at 67% and gradually cool the house to keep it right in a comfortable range.

However, if you have not been home for a while and your home has gotten very warm inside, your air conditioner will come on at full power to get the temperature down quickly. What this really means is that your air conditioner will be running more than a single stage air conditioner because it will sometimes not be using all of its power to cool.

The end result of using a two stage air conditioner is that you will receive a relatively continuous flow of cool air throughout your home. A two stage air conditioner will send in a steady but smaller stream of cooled air as opposed to the large blast of cold air you would get from a single stage system.

This results in a more consistent and comfortable environment overall, and it also makes it possible for the air conditioning system to dehumidify your house more effectively. When the air is cooled too quickly, the dehumidification system does not always have time to do its job. But with the longer cooling cycles of the two stage system, there is plenty of time to make sure the right amount of humidity is removed from the air.

Bathtub Faucets and Fittings

Friday, April 22nd, 2011

Buying new bathtub faucets and fittings can be a lot of fun. But it can also be a bit overwhelming simply because there are so many options out there. And the types of faucets and fittings you choose will have a big impact on the overall cost of the project. That is why it is a good idea to learn a little bit about your options ahead of time so that you know more or less what you are looking for when you actually get into the store.

To begin with, you will have to decide whether you want brass or plastic fittings. Plastic fittings are generally cheaper, but they also do not last as long and are more prone to chipping and cracking. Brass, on the other hand, might cost you a bit more up front, but it will last you longer and serve you better.

Brass faucets and fittings are available in a wide range of styles and finishes, so you can comb through the options to find the one that best fits with the theme you are going for in your bathroom. However, you should keep in mind that some of the available finishes for brass fixtures and faucets require specific care so that they do not tarnish. Make sure that whatever brass fittings and faucets you buy are a kind that you will be willing to care for properly.

You should also keep in mind that the majority of the functional part of your bathtub faucet will be located behind the wall of the tub. That can make repairs and replacement of faulty parts a bit more difficult than on a regular sink faucet, so you want to make sure you do not have to get in there to fix something very often.

And the best way to ensure that is to opt for a slightly higher quality fitting and faucet. It may cost you a bit more up front, but it will be well worth it to you in the long run. Even with these restrictions, there are still plenty of options out there so you should have no trouble finding one that suits your sense of style while still offering high quality performance for a reasonable price.

What Is a Flapper Valve?

Wednesday, April 20th, 2011

Your toilet is not an overly complicated piece of equipment. But in order to work properly, it does require that all of its parts are in the right place and in good shape. Even if something small on your toilet is out of place, it can cause problems like constant dripping or running, improper flushing force or a sudden refilling of the bowl when no one has flushed the toilet.

These problems can sound serious, but many of them are quite easy to address if you know where to look. With most toilets, that place is the flapper valve. The flapper valve is a relatively small rubber plug that fits over an opening at the bottom of your toilet tank. When you press the handle to flush your toilet, the flapper valve lifts up and allows all of the water from the tank to go rushing into the bowl.

The force of this water pushes everything out of the bowl through the drain at the bottom, clearing the bowl and refilling it with fresh water all at once. As long as the flapper valve is able to maintain a tight seal, this process will go along smoothly without a hitch. But sometimes these valves become dirty or simply wear out.

When that happens, water can begin to leak down from the tank into the bowl on an almost constant basis. Depending on the severity of the leak, this may just cause the toilet to run constantly. Or it can even cause periodic “phantom flushes” were the toilet clears the bowl without anyone pressing the handle.

Phantom flushes occur because too much water has seeped down from the tank into the bowl. When the volume in the toilet bowl reaches a certain level, the water in the bowl is forced out, resulting in a flush. This wastes water and can also be pretty startling if you are not expecting it. Fortunately, though, you can usually fix this problem easily enough.

To do this, check your flapper valve to make sure it is keeping a tight seal with the bottom of the tank when not in use. If it is not, you may only need to clean it off to restore the integrity of the seal. In more serious situations, however, you may need to replace the flapper valve entirely. This is not difficult or expensive and can save you a lot of water in the long run.

What Are High-Efficiency Toilets?

Monday, April 18th, 2011

Everyone has a toilet in their home. In fact, you probably have more than one. And you probably do not give much thought to the type of toilet you have. After all, a toilet is a toilet, right? Well, there are actually several different types of toilets, and while they all get the basic job done, there are reasons to favor one type over another.

One such distinction falls on what are known as high-efficiency toilets. These toilets use significantly less water than standard toilets on each flush, thereby saving you money on your water bill every time you use them. No toilet on the market today is permitted by law to use more than 3.5 gallons of water per flush. High-efficiency toilets, by contrast, generally use between 1.6 gallons and 1.1 gallons.

That might not seem like a huge difference, but just think about how many times in a day someone flushes the toilets in your home. That will add up fast. Installing a high-efficiency toilet can save you as much as 12,000 gallons of water a year. And depending on the size of your household and the number of toilets you have, that figure could be even higher.

Of course, a lot of people shy away from high-efficiency toilets because they are concerned about performance. It seems unlikely to them that a toilet that uses so much less water could work effectively all of the time. The truth is, though, that many high efficiency toilets work even better than conventional ones at clearing the bowl in one flush. And high efficiency toilets do not clog any more than regular toilets. In fact, they often do better in that area as well.

Another thing to bear in mind is that toilets last for a long time. This means that the toilet in your home could be quite old. Toilets made before 1980 use much more than modern toilets are allowed to use per flush. Some of them actually go through five gallons or more of water each time you use them. By replacing an older toilet with a new, high-efficiency model, you will be setting yourself up for some significant savings on your water bill each month.

How to Plunge a Clogged Drain

Friday, April 15th, 2011

It is almost inevitable that you will have to deal with a plugged drain somewhere in your home at some point. This drain may be in the bathtub, a sink or a toilet. But wherever it is, a plunger is usually your best bet for getting it out. If you are going to be successful, though, you need to know how to set yourself up and use the plunger properly.

To begin with, remove the strainer or pop-up plug from the opening of the drain. You want the material that is clogging the drain to be able to come back up through that hole when you apply the plunger suction. Next, make sure the sink or tub has enough water in it to cover the head of the plunger completely. A toilet generally has enough water in it already. This water helps to create a better seal for the plunger and allows you to generate better suction, both of which are essential if you are going to dislodge that plug.

You should also make sure you block off any other outlet connected to the drain you are going to plunge. To do this, stuff an old rag or sponge into the overflow opening or into the second drain of a two compartment sink. That will make it possible for the entire force of your suctioning to reach the clog because it will not be compromised by air escaping through an alternate opening.

Now you are ready to plunge. Place the plunger over the opening of the clogged drain. While keeping constant contact with the sink or tub floor, move the plunger rapidly up and down between 10 and 20 times. After the last plunge, pull the plunger off of the sink or tub floor quickly. This should break the seal you have established and help to pull the clog back up the drain towards you.

It can take a few cycles like this before you are able to dislodge the clog completely. But each time you plunge, you are doing more to break up the clog. The pressure from the plunger can eventually get rid of many difficult clogs, so do not be discouraged if it takes a few tries.

How a Garbage Disposal Works

Wednesday, April 13th, 2011

Garbage disposals are becoming more and more prevalent in homes across the country. So the chances are pretty high that you have one in your home. Garbage disposals definitely make getting rid of food waste easier. Instead of scraping all those plates and dishes into the garbage first, you can simply flush it all down the drain, run the garbage disposal and it magically disappears.

But do you really know what is happening when you turn on that wonderful garbage disposal and where all your food is really going? The truth is that a garbage disposal is not a particularly complicated piece of equipment. There are some variations, but in general your garbage disposal has a motor attached to rotating blades which are located in a chamber below your sink that is attached to your drain.

When you put food down the garbage disposal and turn it on, these blades shred the food into small enough pieces that it can pass safely through your drain pipes and out into the sewer system. The shredded food then runs with the water back into your main drainage system and passes out of your house.

This is a pretty simple operation, but there are some things you should be aware of if you use a garbage disposal in your home. First of all, it is important to never reach into the garbage disposal when it is running. If you need to reach in, make sure the unit is switched off. It is even a good idea to shut off the power to the garbage disposal entirely so that it cannot be turned on by accident while your hand is in there.

You may notice a foul odor coming from the garbage disposal after a period of time too. This is common and easy enough to fix, but you will have to get down into the garbage disposal to get rid of the smell. The smell simply comes from residue of the food you have put down the garbage disposal and that needs to be cleaned off so the smell will go away.

Again, make sure you have the garbage disposal turned off completely before you reach in to take parts out to clean them. You can also put baking soda, vinegar or half a lemon down the garbage disposal and run it in order to combat a persistent smell or to keep one from developing.

Types of Septic Systems

Monday, April 11th, 2011

When it comes to septic systems, there are probably more options than you realize. To a certain extent, the type of septic system you choose is determined by the particular conditions around your home. But it is worth learning about the various options so that you can make an informed decision about the kind of system you would like to have.

The more conventional types of septic systems fall into two categories – gravity and pressure distribution. A gravity system, as its name implies, makes use of the force of gravity to drain away waste from your home and into a drainfield.

Gravity systems use gravity to help treat the waste as well, so this type of system requires that you have a particular type of soil and enough space below the ground to allow for proper filtering. If the water table or a layer of hardpan is too close to the ground’s surface around your home, a gravity system may not be an option for you.

Another conventional option is a pressure distribution system. In this setup, a pump regulates the flow of waste from a storage tank to the drainfield. This is the optimal setup if you do not have enough below ground space for a gravity system as the pump makes sure that only the proper amount of waste can enter the drainfield at once and that the waste is distributed evenly when it is pumped in.

There are also several alternative types of septic systems. For instance, mound septic systems are another option to consider when you do not have enough space below ground for a gravity system. In a mound system, the drainfield is actually placed above the surface of the ground and a pump regulates the flow of waste to the field. This allows for adequate treatment before the waste reaches the water table.

Also an option in this type of situation is a sand filter system. This type of septic system incorporates a sand filter holding tank to treat waste before it is allowed out into the drain field. It is another way to make up for the fact that there may not be enough soil to provide adequate filtration but does not require that you build up a mound of earth on your property.

Moisture Barrier for Basement Floor

Friday, April 8th, 2011

One of the most frustrating aspects of a basement, even when it’s finished properly, is the sheer volume of moisture that builds up throughout the year. Because of the natural properties of changing temperatures, the shift in indoor and outdoor environments will cause condensation in your basement which can be damaging not only to your home but to the items you store there.

A moisture barrier is designed to block and redirect moisture away from the things you care about. By keeping moisture outside of your basement, a moisture barrier blocks the buildup of condensation on your basement floor.

Signs You Need a Moisture Barrier

Not everyone needs a moisture barrier. Some basements are better insulated than others. However, if you notice that your basement undergoes a severe shift in humidity and condensation as the weather changes, you should act quickly before it causes damage.

Specifically, look for symptoms that your basement has too much moisture. Rust on your appliances is a big sign of excess moisture, especially above the ground where standing water might occur. Another symptom is mold growing on the wood frames of windows or underneath stairs. If you notice damp spots on foundation walls or peeling paint these are also signs of excess moisture in your basement.

Installing a Moisture Barrier

You now know if you have a moisture problem, but how do you fix it? A moisture or vapor barrier can get the job done. While no moisture barrier is 100% impermeable, they will generally stop most of the moisture that passes from outside to inside when temperatures vary significantly. The type of material used will vary depending on the level of moisture problem you have. Aluminum, plastic, asphalt and metallized film all work well for this.

Beyond a moisture barrier, you can take other actions to stop condensation in your basement. If you keep the air moving, it will reduce a lot of the moisture build up. Moving air with fans in your basement keeps moisture from settling and creating problems. You can also improve your insulation so that temperature is better regulated inside your home.

Moisture barriers are a great tool for stopping damage in your basement. This is only for condensation, however. Make sure, if you have a more severe water problem in your basement that you look into the installation of a French drain, sump pump, or drain tile system.
