What Exactly Are High Efficiency Boilers?

Monday, April 2nd, 2012

You have already read plenty about how energy costs are rising. You know plenty well that heating your New Hope home is a substantial expense, and that the cost of running a boiler is constantly on the rise.

But as technology has gotten better, so have boilers become more efficient at providing heat. It stands to reason that a more efficient boiler is one that costs less to run…but what does “efficient” really mean in the context of boilers? What makes a boiler “high efficiency”?

 What Is a High Efficiency Boiler?

All boilers are rated according to a standardized system of rating efficiency, called the Annual Fuel Utilization Efficiency (AFUE). Essentially, this rating tells you how much heat energy is produced by your New Hope boiler compared to how much energy it draws. The higher a boiler’s AFUE rating, the more efficient it is.

For a boiler to be called high efficiency, it must carry an AFUE of at least 90%. For basis of comparison, older systems carry an AFUE of about 70%, while mid-efficiency systems run at about 82%.

In addition, a high efficiency system has a second heat exchanger for capturing and condensing flue gases, as well as a closed combustion system.

These three things — an AFUE of 90% or above, condensing flue gases and closed combustion – define a high efficiency boiler.

The initial investment in a high efficiency boiler can be costly, but the savings over time in your New Hope heating bills make it well worth the expense.

If you would like a high efficiency boiler installed in your home, give Carney Plumbing, Heating & Cooling a call today!

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!

Top Ten Reasons to Love Geothermal Heating and Cooling Systems

Wednesday, November 3rd, 2010

Here at Carney Plumbing, Heating & Air Conditioning, we’ve been installing geothermal systems for more than a year now. Our entire team is really enthusiastic about them. Our customers rave about the savings and comfort that they get when they upgrade to a geothermal heating and cooling system, and we’re excited to bring this leading-edge technology to the residential consumer.

Geothermal requires an upfront investment, but it’s worth it! Here’s why we love it:

Geothermal offers great green savings for your family!


  1. 70% of the energy used by a geothermal system is renewable (using the earth’s own heat). The rest comes from electric power. A geothermal system makes a huge difference in your carbon footprint.
  2. You’ll never buy foreign oil again. In fact, you’ll never buy oil again, period. One of our first geothermal customers had been burning 5-6 tanks of oil a year (1400-1600 gallons). After installing an all-electric geothermal system, not only did he have no more oil bills, but his overall electric bill was reduced too.
  3. Like to buy local? You can’t get more local than geothermal – 70% of your heating and cooling energy comes from right underneath your feet.
  4. You will increase your home’s safety by not storing fossil fuel on the premises.
  5. You’ll be much less affected by volatility in fuel prices. Remember the high oil prices of a couple of years ago? Consumers in southeastern Pennsylvania may soon see a similar increase when local utilities are deregulated in January 2011 – anywhere from 10% to 40%. With a geothermal system, you’ll feel spikes in energy prices much less.
  6. You can get rid of your old, high-maintenance oil-burning heater and replace it with new, long-lasting geothermal equipment that is designed to last for 20 years.
  7. All of our geothermal customers report that they are now more comfortable in their homes.
  8. Geothermal systems are ultra quiet. They’re installed inside (generally in a basement) so there are no noisy outdoor units.
  9. Federal tax credits for conventional heating systems will run out at the end of 2010, but tax credits for geothermal systems will last until 2016. Also, local utilities frequently offer rebates on geothermal systems.
  10. Carney’s offering a $300 discount on all geothermal heat pump systems!

Our own Kevin Carney was recently interviewed on ACHR. Check out the audio podcast to hear more about his experiences with geothermal systems and his commitment to quality geothermal installations:
