Space Heating vs. an Upgrade to Your Heating System

March 7th, 2011

If your heating system isn’t really cutting it anymore, it may be time to take a step back and consider what your options are. After all, upgrading to an entirely new heating system is a big investment and a large project that will likely disrupt your life at least for a short period of time. However, under certain circumstances it’s the best alternative out there.

One option to consider when you’re unhappy with your home heating situation is supplementing your central heating system with space heaters. These are generally inexpensive and can be placed virtually anywhere in your house or taken with you from one room to another.

Especially if there is a small part of your home that your heating system just doesn’t seem to reach or that you want to keep a bit warmer than the rest of the house, space heaters can be an excellent option. They’re small, safe and portable and can easily keep a smaller portion of your home or room cozy and warm.

However, you’ll have to take into account the operating costs of a space heater as well as the initial investment when you’re trying to evaluate the overall cost effectiveness of this option. Most space heaters run on electricity, which often costs considerably more than oil or natural gas. If your home heating system runs on electricity anyway, this might not be so much of a factor. But if you have an oil or gas furnace, you could wind up paying significantly more to run space heaters as supplemental heat over time.

Also, it’s worth considering that new home heating systems are likely much more energy efficient than the system you currently have in place. Although the initial installation cost can be pretty substantial, you’ll wind up saving a very large amount on your monthly heating bills by upgrading to a newer model.

Plus, you’ll be getting a system that should be able to satisfactorily heat your home without the need for space heaters or other supplemental heat sources. This translates into a pretty hefty savings over time and that’s something you’ll certainly have to take into consideration when you’re evaluating your options.

Propane, Oil or Natural Gas: Which One Should I Choose?

March 4th, 2011

In most cases, you’ll have a choice concerning what type of fuel you’d like your furnace to burn. For most people, this choice comes down to propane, oil or natural gas. The one you choose could significantly impact the cost of heating your home for many years to come, but it’s usually a pretty clear cut decision.

One thing to remember is that most furnaces that burn natural gas can also burn propane. If you don’t yet have a propane tank but are considering getting one, you might not have to make a final decision just yet. Although it’s generally better to set up your furnace for one type of fuel and then leave it that way, you will likely still have the option of converting later on if you should choose to.

If you do have access to natural gas, though, that’s probably going to be your best option. Furnaces that burn natural gas or propane are generally much more efficient than any other type of furnace on the market. You can get them with annual fuel utilization efficiency (AFUE) ratings as low as 80% and as high as 97+%, so that ensures that you’ll be able to find the one to fit your specific situation.

If you’re facing particularly harsh and frigid winters, you’ll want to choose the most energy efficient option available to you and that’s pretty much always going to be a natural gas furnace. Of course, when you’re looking to decide between natural gas and propane as a fuel source, you’ll just want to compare the relative cost for each in your area. For some people natural gas is cheaper, while it’s propane for others. And since your furnace will operate at the same efficiency no matter which of these fuels you choose, you just need to choose the cheapest.

Oil is certainly an option as well, but if you’re looking for a very high efficiency furnace, you’re not going to find one that burns oil. That doesn’t mean that an oil burning furnace might not be a good investment for you. If you don’t have access to natural gas in your area and your heating load isn’t that high, oil might be a perfectly economical choice for you.

If you do opt for a super high efficiency furnace, but don’t have access to natural gas lines, propane is probably the way to go as opposed to oil.

What Is the Most Efficient Way to Heat My Home?

March 2nd, 2011

When it comes to home heating, efficiency is one of the main factors most people take into consideration. There are quite a few different options in terms of home heating, including oil, gas and electric furnaces, heat pumps, and boilers, and each of these have their own set of advantages and disadvantages depending on your own particular situation.

For better or worse, there is no one system that is universally more energy efficient and effective than the others. The one that will turn out to be the best choice for you is the one that fits best with your specific heating needs, the climate you live in and the relative price of the fuel sources available to you.

For instance, if you live in a relatively moderate climate, a heat pump may very well be a good option for you. These systems are able to operate much more efficiently than furnaces because they extract heat from the air rather than generating it themselves. That means that in the winter, a heat pump can take heat from the outdoor air and pump it indoors to heat your home. In the summer, the heat pump can actually do the opposite, taking the excess heat from indoors and transferring it out to provide you with a yearlong temperature control solution.

Heat pumps generally run on electricity which can be expensive, but since they use so much less energy than something like an electric furnace, they can still be a very energy efficient home heating option. However, these systems are not as effective in areas with harsh, long winters, and so would likely require a supplemental heating system as well. Also, the lower the outside temperature, the less efficient a heat pump is going to be.

Furnaces, on the other hand, are quite effective at heating homes no matter how harsh or cold the climate. Gas furnaces are generally the most popular of the models available now, mostly because the cost of natural gas is lower in most areas compared to the cost of other potential fuels.

However, it may be worth considering an oil or electric furnace if these types of energy sources are relatively inexpensive in your area. No matter what type of furnace you get, you’ll be able to choose how energy efficient you want it to be as well, with lower efficiency 80% AFUE furnaces costing substantially less than those with an AFUE of 90% or more.

How Much Will a High Efficiency Furnace Save Me?

February 28th, 2011

The furnaces you can buy these days are all much more energy efficient than those available even 10 years ago. However, that doesn’t mean that all of the current models are created equal. There is still a pretty big variation when it comes to energy efficiency and when it comes to price, so you need to really know what you’re looking for if you want to get the best deal out there.

The first thing you should understand when you’re trying to pick out a furnace is how energy efficiency for this type of equipment it measured. All furnaces come with an annual fuel utilization efficiency (AFUE) rating that reflects just exactly how energy efficient they are.

Any furnace you buy today will have an AFUE of at least 80%, but it’s possible to purchase models with AFUEs of 97% or more. Of course, energy efficiency is generally a good thing, but there are some other things to consider when you’re trying to decide just how energy efficient you need your new furnace to be.

What this calculation really comes down to is how much you’ll be able to save monthly and annually with a higher efficiency furnace. While your heating bills will certainly be lower the higher the furnace’s efficiency is, you will also pay more up front for the highest efficiency models.

This higher purchase price may be worth it, however, if you live in an area with particularly harsh winters. If your heating load is very high and you’ll be using your furnace a lot, your monthly savings will make up for the higher initial price of the high efficiency furnace in a reasonable amount of time.

However, if you live in an area with relatively mild winters and you won’t be demanding a whole lot of your furnace, then the amount you’ll save each month with the highest efficiency models really won’t add up to much.

Keep in mind that a furnace with an 80% AFUE still may be more efficient than your current furnace and will potentially save you a considerable amount monthly when compared to the unit you’re currently using. However, current utility rebates and government tax credits have made 95% AFUE furnaces almost as affordable as less efficient 80% AFUE furnaces.

Can I Use Geothermal Heat if I Live in a Cold Climate Where the Ground Freezes?

February 25th, 2011

Geothermal heat pumps are able to extract heat from the ground, even when outdoor temperatures are well below freezing. They use a system of pipes installed in the ground below or around your home to collect this heat and then return it to your home where it can then be used to heat the air. While these types of heating systems are certainly more efficient the warmer the ground is, they can be effective even in very cold climates.

This is true even in areas where the ground freezes from time to time or for parts of the year because the frozen layer does not typically extend more than three or four feet below the surface. As long as the pipes for your geothermal heating system are below this level, they will still be able to gather plenty of heat from the warmer ground below the frozen layer.

In fact, there are two different ways that the pipe loop for a geothermal heating system can be installed. Most geothermal systems have a horizontal pipe system which sits about four feet below the surface and extends out from the house. This type of installation is typically cheaper than the alternative, but it also usually needs to be larger. Plus, you need to have the space for it to stretch across.

On the other hand, a vertical installation goes straight down into the ground below your home. With a vertical installation, you can usually get away with less pipe overall, but you will probably pay more for the installation because it is harder to drill straight down than it is to dig out a relatively shallow trench to lay the pipe in.

However, if you live in an area that has particularly harsh winters when the ground can be frozen for significant periods of time, it may be worth it to opt for the vertical installation. That is because the further below the surface the pipes go, the farther away they will be from the frozen layer of ground.

With a vertical pipe installation, a geothermal heating system can work quite well in a climate in which the ground usually freezes in the winter. While you will always want to have a backup heating system in place in case of emergencies, this type of heat pump should be all you need under normal conditions.

Will Switching to Geothermal Save Me Money?

February 23rd, 2011

There are simply a ton of different types of heating systems and they are each more appropriate in different situations. However, some are certainly always going to be cheaper to operate than others, although that alone may not make one or the other right for you.

In the case of geothermal heating systems, the operating costs are definitely quite low. But those are not the only costs you will have to think about when you are considering what type of heating system to put in your home to keep your heating bills down.

Geothermal heating systems do not actually generate heat – they absorb it from the ground. Because of this, they actually use very little energy when they are running. All you are really paying to power is the fan that blows the heated air around your house. Also, because geothermal heating systems are more efficient at extracting heat in below freezing conditions than traditional heat pumps, they can continue to keep you warm on their own in more extreme conditions.

Traditional heat pumps, while they also cost very little to operate, do sometimes need to be supplemented by more conventional forms of indoor heating like a furnace when temperatures outdoors get too low. This is not the case with geothermal heat pumps, so if you live somewhere that has colder winters, a geothermal heat pump may be just what you are looking for. Of course, you can always opt for a furnace instead, but these will definitely cost more to run than either type of heat pump.

When you are trying to assess whether or not switching to a geothermal heating system will save you money, you first have to start with the heating bills you currently have. Then, factor in the cost of the geothermal heat pump installation as opposed to the installation of a more conventional system.

You are then in a position to see whether or not the amount the geothermal system will save you each month is enough to offset the higher cost of installation within a reasonable amount of time. Of course, the savings will always eventually add up over time, but if the length of time it will take you to break even is the same or longer than the expected life of the system, it is probably not worth it to invest in this type of heating.

What Is Geothermal Heating?

February 22nd, 2011

Having a geothermal heating system installed in your home means that you will actually be able to heat your home with heat extracted from the ground. If this sounds a bit preposterous to you, you are certainly not alone. But this type of home heating does actually work and the technology is not actually that much different from what is used in a standard heat pump system.

Regular heat pumps are able to remove heat from the outdoor air and transfer it into your house to maintain a comfortable temperature in the winter. You may think that there is no heat in the outdoor air in the winter, but that is not actually the case.

Air contains a substantial amount of heat even at very cold temperatures, and heat pumps are able to work quite well, particularly when the outdoor temperature is above freezing. Conveniently, the same process used to heat your house in the winter can be reversed in the summer to extract heat from the indoor air, providing you with a year round home comfort solution.

Geothermal heating works in much the same way, except that geothermal heat pumps extract heat from the ground rather than the air. In order to accomplish this, a loop of pipes is installed in the ground near your house and your geothermal heating system will pump a liquid, generally either antifreeze or water, through those pipes.

As it passes through the pipes, the liquid will absorb heat from the ground and carry it back to a heat exchanger within your house. At that point, the heat from the liquid will be released into air, which is then blown throughout your house.

And just as conventional heat pumps can cool your house in the summer by removing heat and pumping it outside, so too can geothermal heating systems. They do this simply by letting the liquid flowing through the pipes absorb the heat from inside air and then release it into the ground as it travels through the pipe loop below your house.

Because the ground is never as cold in the winter or as hot in the summer as the air, geothermal heat pumps are actually able to work effectively in more extreme conditions than many traditional heat pumps. However, because they require an entire system of pipes to be installed underground, they can be quite a bit more expensive initially as well.

Compression vs. Cartridge Faucets

February 18th, 2011

If you are like most people, you probably do not think too much about what goes on inside your faucet when you turn it on and off. All you need is for the water to flow when you want it to and to stop when you do not. But when the time comes to replace or repair one of the faucets in your home, it is helpful to know a little bit about how the different types of faucets work and what the pros and cons of each can be.

The oldest and most common types of faucets are compression faucets. When one of these faucets is in the off position, a small washer inside creates a seal that keeps water from flowing through and into the tap. But when you turn the faucet on, the stem inside raises up, which takes the pressure off of the washer and breaks the seal. That allows the water to flow until you lower the stem back down again by turning the faucet off.

These faucets are generally easy to find and relatively cheap. They are also easy to install or repair on your own, and this is fortunate because they do tend to develop leaks periodically. That is primarily because the washer inside will wear out over time and need to be replaced. This is a rather straightforward and simple process, but if you do not want to have to deal with it, you may want to consider your other option.

The other main type of faucet on the market today is a cartridge faucet. Instead of washers, these types of faucets employ a cartridge which seals to the faucet base with several O-rings. These types of faucets can often be quite a bit more expensive, although you can certainly find some that are reasonably priced. They are also much less prone to developing leaks, and when they do they are quite easy to repair as well.

Clogged Kitchen Sink? What Should You Do

February 16th, 2011

Clogs are common in almost every household and place of business. Even if you take special care not to put anything that might cause a clog down the drain, there is a good chance that excess bits of food, grease, hair, or other unsavoury materials and pieces will eventually line and clog your pipes. So, what should you do when a clog takes over your kitchen sink? Here are a few simple steps for quick removal.

1. Disconnect Your Garbage Disposal – Before you do anything, you will need to disconnect the disposal from the sink so you have access to the drain. Start by unplugging your disposal – never work on your sink or the garbage disposal with it plugged in. If the disposal itself is clogged, turn the blades manually to work free any clogs. If it turns freely, the clog might be past the disposal in the pipes and it will need to be removed for further cleaning. Most of the time, however, the clog will be either in the disposal or in the opposite sink.

2. Plunging Your Sink – Once you have ruled out the disposal, it is time to plunge the sink. Make sure to clamp off the line from your dishwasher so that you do not push any water back into the machine. If you have two sink drains, make sure to seal up the one you are not plunging so that a good seal is created. Do NOT plunge the sink if you have poured any chemicals down in an attempt to clear the drains.

3. Cleaning Out the Trap – If a plunger cannot get the job done, it is time to check the P-trap. To do this, remove as much water as possible from the sink and place a bucket under the trap so you do not make too big of a mess. Now, disconnect the p-trap from the trap arm. If you have an older metal sink assembly, you may need a wrench or pliers to get the Slip Nuts free. Plastic is much easier. Check the trap to see if there is a clog in the curve of the joint. If not, you will need to move on to the final possible fix.

4. Snaking – If you cannot clear the clog with a plunger and your hands, it may be time for a snake. You can rent one from most hardware stores if you do not own one, and it is a lot cheaper than calling a plumber to do it for you. You will need to remove the trap arm from the drain itself and then run the snake down the line until you find the clog. This can be a time consuming process, but most often it will take care of any remaining clogs.

Bathtub Drain Plumbing: Things You Should Know

February 15th, 2011

When we think of clogged drains and plumbing problems, we most frequently think of toilets and kitchen sinks, but one of the most common drains to cause problems in a home is the bathtub. To avoid drain problems and to help fix any problems that might crop up, here are some tips for how to handle your finicky bathtub drain.

How the Bathtub Drain Works – A Bath tub drain works the same as the other drains in your home with a simple trap that ensures the safe transfer of water out of your home and blockage of sewer gasses from getting into your home. The drain itself is frequently open with a small crack – roughly a quarter inch – beneath a larger drain plug that can be lowered when you fill the tub. While the space is not large enough for objects like a bar of soap to enter, it is plenty large enough for hair, soap scum, and other small objects from a bath or shower to enter and start clogging that trap.
Cleaning the Drain – To cut down on how much hair and gunk actually gets into the drain you should take off the entire drain mechanism once a week and remove any excess hair. You should also use some form of wire device like a bent coat hanger or scrubber to reach in and remove any hair you can reach. There are specific plumbing devices to help with this as well, but a hanger works just fine assuming you do not have a heavy clog. It is also a good idea to run boiling water through your drain once every week to clear out any soap and hair build up. While most soap is water soluble, it can create a thick, greasy clog when combined with hair. Hot water can help to remove it before a clog occurs.
If a Clog Occurs – If a clog does occur, you should use the hot water method along with a plunger to try and clear out as much of the clog as possible. Avoid chemical use at all costs. Bathrooms are usually small rooms and even with the fan on, the fumes can be dangerous and the chemicals caustic on your pipes and tub. Baking soda and vinegar often help for small clogs, but otherwise, you should move on to a snake for physical clog removal.

If you have a clog deeper than the snake can reach or that you simply cannot affect with the tools listed above, it may be necessary to call a professional who can track your clog into the pipes and find where the root of the problem is. It might be just too deep in your drainage pipe or it could be a completely different area of your plumbing system.
