Saving Money by Heating the Crawl Space

Monday, January 17th, 2011

If you’re like most people, you probably focus on how to keep the living areas of your home warm and comfortable in the winter months. Of course, you want to do this with as little expense as possible and so insulating and heating all of the rooms of your home naturally makes sense. The main goal of this is to eliminate any areas where heat might be able to escape, thereby causing you to spend more and run your heating system for longer to keep the temperature indoors at an acceptable level.

What you might not often think about, however, is the fact that the crawlspace under your floors is probably not insulted at all. Of course you and your family don’t spend much time there, but if you’re trying to keep your home comfortable for as small a price tag as possible, this is something you should think about addressing.

There are actually several reasons that heating and insulating your crawlspace can save you money in the long run. For one thing, the ducts and pipes that carry your heated air and water to various locations throughout your house generally run right through these very crawl spaces. Even with an average amount of insulation surrounding those pipes and ducts, you’ll still be losing heat to the outdoors as the air and water travel through the crawl space.

Of course, pumping heat directly into the crawl space would be a waste too, since there is no insulation to keep it there. With the proper amount of insulation, however, you can easily heat your crawl space with very little energy and potentially save a ton in the long run.

When your ducts and pipes are traveling through a heated space, they’ll retain the heat they started with and bring that to the rest of your home. You’ll pay very little to keep the crawl space warm and you’ll save a lot by conserving the heat and hot water that you do generate to keep your house comfortable.

Plus, because your crawl space is generally located directly underneath the floor, you’ll be protecting the actual rooms of your home from heat loss as well. And you floors won’t be so cold to walk on either. Overall, there really is no reason not to take the time and have your crawl space properly insulated and heated.

The Energy Star Label

Friday, January 14th, 2011

The Energy Star program is a joint program of the US environmental protection agency and the US department of Energy. The program’s goal is to help consumers save money and protect the environment through energy-efficient products and practices.

The best-known aspect of the Energy Star program is the Energy Star label, which is awarded to appliances and other items that are significantly more efficient than average. Energy Star efficiency guidelines vary depending on product category, but in general, Energy Star products use 20%-30% less energy than minimum federal standards.

The Energy Star guidelines were designed both with energy efficiency and performance in mind. While low energy use is one of the most important criteria for selecting Energy Star appliances, product performance, features, warranty, safety, and durability are also taken into account. Price is also a factor: if a product costs significantly more than other products in its category, it will only receive the Energy Star label if the up-front cost will be recovered through savings in operating costs within a reasonable amount of time.

The first Energy Star labels were given to computers and monitors in 1992. Now labels can be found on many other products, including:

  • Furnaces
  • Hot water heaters
  • Air conditioners
  • Dishwashers
  • Refrigerators
  • Light bulbs (florescent and LED)
  • TVs

Energy Star products can be found wherever appliances and electronics are sold. Look for the blue and white Energy Star label. You can also look for the yellow EnergyGuide label that is affixed to most heating and cooling systems and household appliances. This label is created by the Department of Energy and shows a product’s annual cost of operation compared to similar models. It will often indicate whether a product is Energy Star.

It’s important to note that while an Energy Star label indicates that a heater, air conditioner, or household appliance is more efficient than the minimum guidelines, it does not always mean that you are getting the most energy efficient option on the market. If you are making a major appliance purchase, use the Energy Star label to be sure every model on your “short list” is energy efficient. Then, look carefully at the EnergyGuide label to compare the efficiency of the models you are considering.

The EPA has also extended the Energy Star label to cover new homes and commercial and industrial buildings. To qualify for the Energy Star rating, a new home must use at least 15% less energy than standard homes (built to the 2004 International Residential Code). Energy Star homes usually include insulation, high-performance windows, energy-efficient heating and cooling systems, appliances, lighting, and water heaters.

The Energy Star standards and label have been recognized in many other countries, including Canada, Australia, Japan, New Zealand, Taiwan and the European Union.

Attic Insulation – Does it Save You Money?

Wednesday, January 12th, 2011

While you may not spend too much time up in your attic in the winter – or at any time of year for that matter – the conditions up there can end up having a significant impact on the size of your heating bills. Fortunately, if you’re leaking heat out of your attic like crazy, there is something you can do about it. And it won’t even take you a lot of time or cost too much, but it will save you a ton of money in the long run.

So what is it that you can do to magically save so much on your heating bills? Well, the truth is that all you really need to do is insulate your attic properly. Since the attic isn’t typically a space that people occupy often, builders often leave these areas uninsulated. That means that they’re pretty cold in the winter. But if you’re not sitting up there, does it really make any difference?

Absolutely it does. The problem with having an uninsulated attic is that heat rises and so will quickly move to the highest point in your home. This is the attic, of course, and if the attic isn’t insulated, all of that warm air that you’ve been paying to heat will go right out the top of your house. Even if the door to the attic is shut up tight, you will still be losing heat into it.

And if the attic isn’t insulated, chances are that there’s no insulation anywhere above the ceiling of the top floor of your house. With heat continually rising and escaping out of the top of your home, you’ll find that your home heating system has to work much harder to keep the house at a comfortable temperature. And the harder your heating system works, the more you’re paying in energy bills each month.

Fortunately, adding insulation to your attic is relatively easy and won’t cost you much at all. And the savings you start to see immediately on your energy bills will more than make up for the expense of having the insulation installed. Even if your attic does have some insulation in place already, it may be worth checking to make sure it’s still working well. Some types of insulation simply break down over time and you might not be getting anywhere near the protection you thought you were.

When Should You Replace Your Existing Heat Pump?

Friday, January 7th, 2011

Nobody wants to think about having to replace a home heating and cooling system. It’s a big job and a new system probably won’t come cheap – not if it’s worth buying anyway. But in the end, you’ll be better off replacing your heat pump sooner rather than later if you start noticing signs that it may be on its way out.

So what are these signs? Well, they’re actually pretty easy to recognize if you know what to look for. For instance, if your heat pump is suddenly making more noise than it used to, there’s a good chance that something’s going wrong inside. This may only require a minor repair, but if minor repairs like this become a regular occurrence, you should start seriously thinking about looking around for a new system.

The cost of even minor repairs will certainly add up quickly over time, and you’ll have to seriously think about whether it makes financial sense to continue to repair an older system rather than simply replacing it with a new one. Chances are that you’ll have to invest in a new one anyway, and the sooner you do it, the less you’ll have paid for repairs to a system you were just going to get rid of anyway.

Also, if you’re starting to notice humidity problems in your home or if some parts of your house are being kept warmer than others, it may very well be a sign that you heat pump isn’t working like it should. Again, this can sometimes be rectified with repair work, but especially if your heat pump is 10 years old or more, it probably makes more sense to replace it.

Another item to keep an eye on when you’re worried about how well your heat pump is working is your monthly energy bill. If you notice a sudden or even a gradual but steady increase over time that you know isn’t a result of an increase in energy prices in your area, you should suspect that your heat pump isn’t working like it should.

Even if it’s still keeping your home at a comfortable temperature, the fact that your heat pump is using more energy to do it is a sign that there’s something wrong with your system. Plus, newer systems are generally more energy efficient anyway, so you’ll be making up for the initial investment of purchasing a new system when you start paying even less on your monthly energy bills.

Dear Santa, Please Bring Me Some New Plumbing Accessories (Really!!)

Wednesday, December 22nd, 2010

When most people think of holiday gifts for their family, chances are they’re not considering…plumbing. But maybe it’s time to think again. Everyone uses toilets, sinks, and showers every day – which means that making improvements to your plumbing will make your entire family more comfortable, every day! The right plumbing upgrades can help your family enjoy mornings more, get fewer colds, savor great European style, and save money on utility bills (money that you can put towards that new car, or a dream vacation).

Plumbing upgrades are also a great green gift. They save water and energy, and they last for years – much better than cheap, disposable stuff that will just wind up in the landfill.

So, while we’re not necessarily recommending that you completely forget about jewelry, toys, and electronics, we do think you should consider adding plumbing improvements to your gift list.

Here are some suggestions for some great, relatively inexpensive plumbing improvements that your family will enjoy every day:

  • Insulate your hot water pipes, and put a blanket over your hot water heater. This is often touted as a money-saving measure (and it is) – but it has the wonderful side effect of making your water hotter as it comes out of your sink or shower. You can’t put this under the tree…but wouldn’t your family enjoy waking up to lovely warm showers on Christmas morning? This is a great gift if you’re strapped for cash, because the materials for insulating your pipes and heater are very inexpensive – the biggest part of the gift is a couple of hours of your time and effort. (Read our blog post on insulating your hot water pipes to find out how easy it is to do.) [Link to: http://www.milani.ca/blog/plumbing/prevent-frozen-pipes/]
  • Replace your old water-saving showerhead with one of the new-generation water-saving showerheads. Those old aerators were virtuous, but they can be chilly and a little prickly.  With the right new showerhead, you’ll never even know that you’re saving water – you’ll just feel like you’re in a luxury hotel. You can get a wide range of fun styles and functions, including rain showerheads, massage showerheads, you name it. (Pair a new showerhead with insulating your pipes to really kick your family’s shower experience up a notch!)

Carney Plumbing, Heating & Cooling featured in The Air Conditioning, Heating and Refrigeration NEWS

Tuesday, December 21st, 2010

Carney Plumbing, Heating & Cooling was featured in The Air Conditioning, Heating and Refrigeration NEWS for its recent expansion into the geothermal market. (“PA Contractor Jumps into Geothermal”, December 13, 2010) The NEWS’ coverage highlighted the perfect match between the rigorous demands of geothermal installations and Carney’s long-time company philosophy, which focuses on offering customers the best value for their money rather than the absolute lowest price.

With geothermal systems in particular, the NEWS notes, skimping on quality to reduce price can be disastrous. Installing a geothermal loop requires excavation, which means that it’s important to get everything right the first time. If a low-bid contractor tries to cut corners by shortening the loop, only to find that the system doesn’t put out the right BTUs, re-excavating to extend the loop will be extremely costly – perhaps even prohibitively expensive.

To make sure this doesn’t happen to its customers, the Carney geothermal team checks and double-checks its load calculations to be sure that they install a geothermal loop that is the right size for the home. Carney also requires extensive training for all their geothermal installers, and will pay for any additional geothermal training an employee requests.

(Read more about how Carney makes sure that it gets its geothermal systems right every time.)

The NEWS article also emphasized the economic advantages of geothermal heating and cooling systems. Geothermal systems require an upfront investment, but they’re designed to last for 20 years, so a geothermal heating and cooling system is a great long-term addition to a home. Federal tax incentives and local utility rebates can help offset the installation costs, making the initial outlay much more affordable. The increase in comfort and the reduction in utility bills are immediate – and, the NEWS pointed out, the savings will only increase over time as the price of oil goes up and Bucks-Mont utilities are deregulated, leading to potential double-digit utility rate increases.

(Read more about why geothermal systems are well worth the upfront investment.)

Owner Kevin Carney is excited about the potential for geothermal. He told the NEWS that when installed properly, nothing comes close to geothermal “in terms of comfort, reduced energy expenditures, and equipment longevity”. One of his employees has already made the switch to geothermal, and Carney himself is planning to install a geothermal system in his next home.

Dual-Flush Toilets: Another Great Green Plumbing Innovation

Wednesday, December 15th, 2010

If you’ve traveled to Europe or Australia, you’ve probably seen toilets with two buttons instead of a single flush handle. Pressing one button flushes the toilet lightly to remove liquid waste, and pressing the other produces a higher-volume flush to remove solid waste.

Originally designed for drought-prone Australia, these water-saving toilets are becoming increasingly popular in North America as well.

Standard 1.6-gallon toilets are a great improvement over older toilets, which used 3 or even more gallons per flush. But dual-flush toilets are even more water-efficient. A “full flush” uses 1.53 gallons per flush, and a “half flush” uses only 1.02 gallons per flush. The result is a reduction of up to 68% in water usage over a conventional toilet (and even more if your conventional toilet is old and leaky).

Of course the savings vary from person to person, but if you use the toilet an average of 5 times a day, you’ll save close to 600 gallons of water every year. For a family of four, that works out to a total savings of 2400 gallons annually. And, since toilet usage typically accounts for roughly a quarter of your water bill, you can end up with a monthly savings of close to 17%.

Another benefit of dual-flush toilets is that most models have a larger trapway for removing waste than conventional toilets – which reduces the likelihood of a clog.

Finally, dual-flush toilets look great. They are sleek, modern, and European-looking, and they perfectly complement a high-end bathroom.

Plumbing Is Going Green! Start with Simple Upgrades to Your Faucets and Showerheads

Wednesday, December 1st, 2010

When people talk about “green building”, they’re typically referring to energy-efficient heating and cooling appliances, insulated walls and windows, and sustainable materials. But these days “green plumbing” is getting increasing attention – and rightly so, because water consumption is a major factor in the environmental footprint of any building! The green plumbing movement is being led by drought-prone Australia, where it’s even possible for plumbers to earn a Green Plumbing Certification.

“Green plumbing” helps the environment by doing one or more of the following:

  • Saving water
  • Saving energy
  • Using environmentally-friendly materials

In the US, LEED Certification is becoming increasingly popular, which means that green plumbing systems are being installed in many new or substantially renovated buildings. But green plumbing improvements don’t have to be big and expensive. In fact, they start at under $20.

Over the course of the next few blog posts, we’ll look at a range of green plumbing upgrades – some that you can do yourself, and others that require professional assistance.

In this first post of our “Green Plumbing” series, we’ll look at the simplest and most affordable green plumbing upgrade you can make: installing low-flow faucet accessories and showerheads.

How do low-flow showerheads and faucet accessories work?

Low-flow showerheads and faucet accessories (often referred to as aerators, which is the most popular type) attach to existing fixtures. Normal-flow showerheads use about six to seven gallons per minute (GPM), and the water comes out at about 80 psi (lbs per square inch, a measure of pressure). Of course, if you try to use less water with a normal showerhead, the stream is flat and insubstantial – a very unsatisfactory shower experience. Low-flow showerheads solve this problem by forcing the water into a narrower opening, which reduces the amount of water that comes out, but maintains the pressure at 80 psi for a nice strong stream. (It’s like partially blocking the end of a hose with your thumb to increase the force of the water coming out – except that low-flow faucets and showerheads reduce the size of the stream only a little, just enough to maintain existing pressure with less water.)

Low-flow faucet accessories work the same way.

There are two different kinds of low-flow faucets and showerheads:

  • Aerating faucet accessories and showerheads mix air into the water stream for steady pressure. The steady stream sensation is very popular with consumers. However, mixing air into the water can lead to a reduction in water temperature, which can be a drawback for showers during the winter months.
  • Non-aerating faucet accessories and showerheads don’t mix air into the water, which results in a pulse-like rather than a steady-state stream. Not everyone likes the pulse effect, but those who do say it feels like a gentle massage. Non-aerating faucet accessories and showerheads maintain water temperature very well.

How can you tell if you need a low-flow faucet or showerhead?

The EPA standard for new residential lavatory (bathroom) faucets is 1.5 GPM (gallons per minute). Your current faucet may have an aerator on it already, and if it does, it will have the GPM stamped on the side. If the GPM of your existing aerator is greater than 1.5, you should upgrade to a new high-efficiency faucet aerator. If you don’t have an aerator, check to see if the inside of your faucet has threads (grooves) for an aerator to be screwed into it. If it does, install an aerator.

If you already have a low-flow showerhead, check the side of the showerhead to see if it has a flow rate of 2.0 GPM (the new EPA standard for showers). If you don’t already have a low-flow showerhead, you can test your shower to see if its flow rate is too high. Put a two-quart saucepan on the floor of the shower and position it in the middle of the shower stream. Turn the shower on at full pressure and count how many seconds it takes to fill the pan. If it takes fewer than 15 seconds, you would probably benefit from a high-efficiency showerhead.

How much water will a high-efficiency faucet or showerhead save?

It depends on how much water your sink or shower used before you installed the upgrade. The only way to know for sure is to check your utility bills over the next few months and compare them to the same time period during the previous year. If you want to feel good about your decision right away, you can get a rough estimate as follows: assume that your current showerhead uses 2.5 GPM (this is a very common flow rate for modern showerheads). A new 1.5 GPM showerhead will make your shower 40% more efficient. Use your utility bill to calculate 20% of your total water usage (this is the amount typically used for showering), then take 40% of that number. Multiply this by your cost-per-gallon, and you’ll have your savings!

How do I find high-efficiency faucet accessories and showerheads?

When you go to your local plumbing supply store, look for the EPA WaterSense label. This is the equivalent of the EnergyStar label, and all products bearing this label meet the new EPA water use guidelines.

Geothermal – Get It Done Right!!!

Wednesday, November 10th, 2010

As we wrote in last week’s blog post, everyone at Carney Plumbing, Heating & Cooling is really excited about geothermal energy systems. But…geothermal only works well when it’s installed correctly. If it’s not, then the geothermal system you install could wind up being nothing more than expensive waste of money – and you might even end up using more energy than you did before, not less.

In this blog post, we’ll explain how we make sure that we install geothermal systems properly so that our customers enjoy maximum comfort and savings.

To explain the secret to a successful geothermal installation, first we should explain how geothermal systems work.Arrows and blocks

Although the temperature above the ground can vary widely from summer to winter, the temperature underneath the ground stays fairly constant all year round, thanks to the hot molten rock that underlies the earth’s surface. Depending on latitude, the level of volcanic activity in the area, and the depth at which the geothermal system is installed, the underground temperature can range from 45 to 80 degrees Fahrenheit. Geothermal systems use underground pipes, called a loop, that circulate fluid in a loop into your house and back under the ground. In the winter, the loop brings heat up from the ground into your house, where it is distributed throughout your house via ductwork. In the summer, the loop pulls the hot air out of your house and discharges it underground.

So, what’s the secret to a successful geothermal installation? The most important thing is to correctly calculate the load (i.e. the number of BTUs the system has to generate to keep the house comfortable). This will ensure that the geothermal loop, and the equipment that keeps the fluid moving in the loop, are properly sized. If a contractor has cut corners by making the loop and the circulation equipment too small, the system will not keep your home comfortable.

At Carney, we receive a couple of calls every month from worried homeowners who are not comfortable with the geothermal systems they’ve had installed by other companies. When a Carney technician goes to check it out, we almost always find that the loop and the equipment are not big enough to properly regulate the temperature of the home. Although the smaller loop may reduce the cost of the initial installation, this is a false savings. A homeowner will have to supplement an improperly functioning geothermal system with other means, or sacrifice comfort – and the home’s overall energy consumption might even go up, not down, as a result! At Carney, we call this “getting geothermal in name only”, and we’re always upset when we see homeowners who’ve had this happen to them.

So how do we make sure this never happens to our customers? We start by making sure that all our technicians are fully trained. In addition to mandatory training, we encourage our technicians to sign up for whatever additional training they want – on us.

We also take great care when we design our geothermal systems – in fact, we probably spend more time on design than we do on actual installation. We do all our load calculations by computer and by hand so that we are sure of our results. And we get as many different minds working on the design as possible – for example, we ask drillers to provide their own independent assessments to make sure they tally with ours.

Our philosophy when it comes to geothermal is, “You cannot cut any corners.” We make sure we don’t – we pay attention to all the details so that when your geothermal system is done, all you have to do is relax and enjoy it!
