How is Geothermal Heating Different than a Boiler or Furnace?

October 8th, 2012

If you need a new heating system in Quakertown, there are quite a few options to choose from. But before we can talk about the differences between boilers, furnaces and geothermal systems we need to understand how they work.

How is geothermal heating different from a boiler or furnace?

No fuel required, unlike boilers and furnaces that rely on oil or gas combustion, geothermal systems tap into the Earth’s consistent underground temperature (around 55 °F) for heating and cooling.
Energy from the ground, a liquid (like water or an antifreeze mix) circulates through buried loops where it either absorbs heat from the Earth or releases indoor heat into the ground.
Heating and cooling using the same principle, in winter, the system draws warmth from the ground to heat your home; in summer, it reverses the process to cool your home by transferring heat back into the ground.
Only electricity needed for operation, the only energy used is for running the heat pump that moves the liquid and the air handler that distributes conditioned air throughout your home.

How a Boiler Works

Boilers, like most traditional heating systems, require a fuel source, normally oil or gas, which is combusted in exchange for heat. In the case of a boiler, that heat is transferred to water that is circulated to radiators in each room where the heat from the water is expelled into the air.

How Furnaces Work

With furnaces, the heat generated by the burning of fuel is transferred to a piece of metal called a heat exchanger. The furnace blows cool air from the house over the heat exchanger which warms the air and it is then delivered to the rest of the house using a series of ducts.

How Geothermal Systems Work

A geothermal system uses a pump to circulate liquid, sometimes water or a mixture of anti-freeze and water, into the ground where it is either heated or cooled—depending upon the needs of the people in the house. This process makes geothermal technology unique, and you can explore further in our guide to geothermal environmental benefits.

The Differences between Boilers, Furnaces and Geothermal Systems

The main difference between a geothermal system and a boiler or a furnace is that it doesn’t require any kind of fuel source. The energy for the geothermal system is actually in the ground. If you dig about 10 feet into the ground, the temperature of the soil stays at an almost constant 55° F no matter what the temperature of the air is above it. When the air in the home needs to be cooled, a geothermal system absorbs the heat from the air and transfers it into the ground. Learn more about why cooling with geothermal systems is so efficient and sustainable. When the home needs to be warmed, the process is reversed: heat from the ground is absorbed by the liquid in the pipes and transferred to the air in the home.

The only energy being used is the electricity to run the heat pump that circulates the liquid in the pipes and the air handler to distribute the conditioned air. This is why homeowners often see major savings—discover how a geothermal installation saves energy compared to conventional heating systems.

Frequently Asked Questions

Question: How does a boiler heating system work?
Answer: A boiler burns fuel like oil or gas to heat water. That hot water is then circulated through radiators or pipes, which release warmth into the rooms.

Question: How is a furnace different from a boiler?
Answer: A furnace burns fuel to heat a metal heat exchanger. Air is blown across this exchanger and then distributed through ductwork to warm the living spaces.

Question: What makes geothermal heating fundamentally different from boilers or furnaces?
Answer: A geothermal system doesn’t burn fuel, it uses the stable temperature of the ground to exchange heat. A liquid circulates underground via a heat pump, extracting warmth in winter or storing heat in summer, using only electricity to power the pump and air handler.

Question: Why is the ground a reliable source for geothermal heating?
Answer: At about 10 feet below the surface, the ground maintains a nearly constant temperature year-round, around 55°F, making it an efficient source to absorb or release heat regardless of outdoor air conditions.

Benefits of Heating Maintenance for Your Furnace

October 1st, 2012

Your furnace is like any other piece of equipment in your Langhorne home in terms of what it needs to continue to function at a high level – namely, routine professional maintenance. Even if your furnace is relatively new, it’s never too early to start planning to keep it in good working condition for years to come. Routine heating maintenance is the best way to ensure your furnace will always work when you need it to.

Better Energy Efficiency

One of the most immediate benefits of regular furnace maintenance is the boost you’ll see in your system’s energy efficiency as reflected in lower energy bills going forward. Even the newest, most efficient furnace will lose a measure of its energy efficiency every year. While this drop might not be noticeable at first, it will quickly add up to create higher heating costs for you. But a simple tuneup every year from a Langhorne heating technician can almost completely eliminate this loss in efficiency.

Fewer Repairs

A regular checkup also allows an experienced technician to go through your entire heating system to find any parts that need to be replaced and other issues that could cause problems later on down the line. Addressing these small issues early makes it less likely you’ll need emergency repairs in the middle of winter when your heating system suddenly shuts off. And that saves you both money and aggravation.

Avoid Premature Replacement

Keeping up with regular furnace maintenance will also extend the life of your system, making your initial investment go farther and allowing you to postpone replacement. And that’s always a good thing for your budget as well as for your peace of mind.

With so many benefits stemming from routine maintenance for your heating system, there really is no reason not to get it done. It’s actually quite a quick and inexpensive process, and you’ll be able to rest easy knowing that you did everything you could to make sure your family is warm and comfortable all winter long.

Heating Guide: Boiler Maintenance

September 24th, 2012

If you own a boiler in Jamison, regular maintenance is very important. Performed in the fall, before your boiler is turned on for the first time, this maintenance will ensure your system works properly and efficiently for the coming months. Here are a few of the tasks performed by a Jamison heating professional during a maintenance call visit:

Clean Surfaces – The front and rear doors to the boiler are removed and the surfaces are all vacuumed and cleaned carefully.
Gasket Repair – All gaskets on the doors are checked and replaced if necessary to ensure your system works properly. Similar repairs are performed on the hand hole and man hole plates and the low and auxiliary low water cut off controls.
Burner and Pilot – The burner plates and pilot light are thoroughly inspected and cleaned. A technician will also check the pilot electrode and then test the pilot to ensure it works as intended.
Air Damper – The air damper and blower are both cleaned and tested for potential issues before turning back on.
Burner Adjustment – The burners are tested and adjusted for proper combustion and tests are performed to ensure the flame is right. Flame safeguard and safety trip checks are also performed to ensure the system will turn off as needed.
Control Piping – The control piping plugs are removed and cleaned, as is the entire pathways between

Boiler maintenance is the most effective way to ensure your heating system continues to work properly throughout the coming winter. Because of the nature of a boiler and the fact that most systems use natural gas or oil, it is important that a professional be the one to perform the above tasks.

Steps to Take When Your HVAC System Breaks Down

September 17th, 2012

If your Chalfont heating or air conditioning system breaks down, there are a few simple steps you should take before calling a professional. Here is a rundown of exactly what you should do and how these steps will ensure the system is fixed quickly and properly to help keep your family comfortable at all times.

Check the Power – First, check the electrical power to your system. Look for a blown fuse or flipped circuit if the system won’t turn on at all. If this is the problem, watch for a recurrence. If it happens more than once, you should call a professional to fix the problem in the future.
Check the Thermostat – Check all of your thermostats to ensure they are not only reading the proper temperature, but that they are set to the right temperature. Often, what seems like a big issue can simply be due to a thermostat being set wrong.
Inspect the Outdoor Unit – Check outside for debris or brush around your condenser unit. This can block air flow and cause the system to shut down.
Inspect the Indoor Unit – Check your indoor units for the same buildup of debris around them and for any other issues like dirt or dust on the coils.
Check the Filters – While a clogged filter would not necessarily shut down an HVAC system under normal circumstances, it could lead to such a problem if it gets bad enough.
Call a Professional – Finally, if you try everything listed above and you cannot get your air conditioner or heating system to turn back on or run consistently, now may be the time to call a Chalfont heating professional for a thorough inspection. This is when it could be a real breakdown which is likely more costly to repair.

If you have a problem with your air conditioner or heating system, definitely check common issues that could have led to the breakdown, but always call Carney Plumbing, Heating & Cooling if real repairs are needed.

Why Should I Be Concerned about the Refrigerant in My Old AC System?

September 10th, 2012

All old ACs used R-22 refrigerant to carry out cooling functions. In fact, R-22 has been the choice for global AC systems for decades now. But did you know that this refrigerant can be a real danger for the environment? R-22 is one of the more harmful greenhouse gasses and it can cause serious damage to the Ozone layer.

In fact, R-22 has been banned in most places and is going to be phased out by the year 2020. Most manufacturers have stopped using this refrigerant and it is going to be increasingly difficult to find on the market. R-22 is also going to become more expensive in the near future. In fact, the trend has already caught on in most parts of the world.

Considering the amount of damage R-22 causes to the environment, you don’t really need more of a reason to consider changing refrigerant from your Ambler home’s old air conditioner. The best and most recent answer to this issue is the use of another refrigerant known as R-410A. This refrigerant is being marketed under different names by various manufacturing companies but it is essentially the same thing. Though you will still find R-22 refrigerant till the year 2020, it is still a smarter option to make the switchover as early as possible. If you can do your part towards helping the environment, why not do so at the earliest time possible?

Will Geothermal Add Value to My Home?

September 4th, 2012

If you are currently considering having a new geothermal system installed in your Abington home you may wonder if that big investment will pay off if you decide to sell your home before the payoff period begins. Because any energy efficient upgrade for your home will take many years to pay off, it is important to know whether it will have a positive impact on the perceived value of your home.

To date, it has been hard to determine if people actually see an increase in home value after having a geothermal system installed. On paper it would make sense for there to be such an increase in value because the system reduces the cost of heating and cooling month after month, year after year. However, geothermal systems are relatively uncommon still so data about such sales is limited. Because most home valuing occurs in comparison to the sale of nearby homes, it would be hard to determine the impact in any one neighborhood unless a nearby home of a comparable size and with a geothermal system installed was sold recently.

Another factor to consider here is the perceived problems that come with a geothermal system. The technology is new and a potential buyer may be nervous about having to deal with a new system they do not understand and that could conceivably break at some point in the future. They may not even realize it is a unique form of heating and cooling or that there are substantial energy savings involved in having such a system.

Despite all these potential drawbacks, however, most realtors believe that green homes have a slightly higher value than those that are not considered green. A study conducted in 1999 showed that home values tended to increase by as much as $20 for every $1 per year saved in energy costs. Recent studies have shown similar interest in energy savings over what is considered the standard and real estate agents are increasingly using tools to pinpoint green energy homes for those seeking such options.

While there is no way to be certain how much a geothermal system will affect the value of your Abington home, it is relatively safe to assume that such an upgrade will have a positive impact on its value.

Why is it Important to Keep Your AC Condenser Coils Clean?

August 27th, 2012

Condenser coils perform an essential function of conditioning hot, moist air and replacing it with cool, dry air. During this process the continual circulation of air causes airborne pollutants such as dirt, dust, grass, lint, moisture and other debris to land on the coils, building up until it gets clogged. A clogged or dirty AC condenser coil is most definitely a problem.

The main problem with dirty coils is that it decreases how well the AC actually cools. A clogged coil can mean deceased air flow through the coils, which in turn means your Doylestown air conditioning system will be less efficient. Routine AC tune-ups in spring are a great way to ensure your condenser coils stay clean and your system performs at its best.

Clean condenser coils can yield higher performance levels, cleaner indoor air, and a longer life expectancy of the unit, while also saving money in electricity costs. Performance levels of air conditioners with dirty coils drop by as much as 30%! Scheduling professional AC maintenance ensures that coils are cleaned properly and potential issues are caught early.

When air passes over a dirty condenser coil and is then pushed into indoor air after being cooled it only stands to reason that some of that dirt and debris gets taken indoors as well. It can also cause moisture problems on the coils which could result in bacteria or mold spores growing, and might reduce indoor air quality in your home. These risks are why it’s important to prevent mold growth inside your AC through proper maintenance and coil care.

Dirty coils can also cause the AC to work at higher temperatures and higher pressure which means the lubricant cannot easily be broken down. This can make the unit freeze over, eventually causing compressor failure.

Carney Plumbing, Heating & Cooling can help clean your condenser coil during a regular AC maintenance checkup – give us a call today if you need AC service!

Benefits to Cooling Your Home with Geothermal

August 20th, 2012

According to the U.S. Environmental Protection Agency, geothermal heating and cooling systems are one of the most energy-efficient, eco-friendly and cost-effective systems on the market today. Call Carney Plumbing, Heating & Cooling with any questions you have about geothermal technology.

Cooling with Geothermal Has its Benefits

Cooling indoor air with geothermal energy has a number of benefits. Geothermal systems are highly energy-efficient, environmentally friendly, cost effective and have long service life expectancy. Because of the unique method of pulling cold temperatures from the ground or water through loop systems with a geothermal heat pump, geothermal systems are much more energy-efficient than even air-source heat pumps.

Geothermal energy is a renewable, sustainable energy source decreases your dependence on combustible energy sources. Along with a significantly decreased reliance on combustible energy sources comes the added benefit of being highly cost-effective.

Since loop systems are placed underground and there are few moving parts to the heat pump, geothermal systems are known to last considerably longer than traditional air conditioning systems.

Geothermal energy can be pulled from the ground all year round through the geothermal heat pump, so during summer you can have cool air and during winter you can have warm air indoors. This means year-round indoor comfort with one air conditioning and heating system, a great benefit.

As geothermal contractors in Langhorne, Carney understands everything about geothermal cooling systems and can help you determine whether it is the right cooling and heating system for your specific needs. Contact Carney Plumbing, Heating & Cooling today!

Benefits of Forced Air Systems

August 13th, 2012

Forced air systems are usually hooked up to both a heating element and an air conditioning element, both of which send their pre-treated air through a series of ventilation ducts located throughout a building. Many times the heating and air conditioning devices are separate, such as a gas furnace for heating and a central air conditioning unit for cooling. Other times they can be one and the same unit like with packaged air conditioners and heat pumps which does both jobs with one machine. This makes for a great deal of variety in the choices of heating and air conditioning types that are available for use.

With use of a programmable or digital thermostat there is a high degree of control with a forced air system. You can Set time-of-day and day-of-week settings to accommodate when the building is in use and when it is not. There are also options for setting temperatures in certain sections of your home while other sections remain untouched. All of this allows for lower utility bills, since only the rooms which are used frequently are heated or air conditioned.

Air conditioners and heaters utilized today have much higher energy efficiency ratings than those of years past; couple this with a well maintained, properly sealed, insulated and balanced duct system and the energy-savings increase even further.

Forced air systems cost anywhere from 40% to 60% less to install than comparable radiant systems. They also offer special features such as filtration systems and ultra-violet germicidal lights, which can keep your indoor air clean and healthy.

Carney Plumbing, Heating & Cooling is an air conditioning and heating company in Horsham that provides quality HVAC services to each client. Let us assist you in determining which forced air system is right for your unique needs.
