Tax Credits Now Available for Geothermal Systems in Indiana

Geothermal heating and cooling systems generally achieve a minimum of 400 percent energy efficiency, and when compared to the highest range of energy efficiency for traditional systems (92-94 percent), many users consider the systems a worthwhile investment. While geothermal systems for residential areas present a large up-front investment, initial costs are recouped in monthly utility bill savings. Homeowners wanting to take advantage of every opportunity to ease the cost of installation to convert to a green system can now reap the benefits of tax incentives.

The Residential Energy-Efficient Property Credit, available now through 2016, is meant to help U.S. taxpayers pay for qualified residential alternative energy equipment, such as solar electricity systems, solar hot water heaters, and geothermal heating and cooling systems. The tax incentive offers a 30 percent tax credit to homeowners for upgrading to a “Qualified Geothermal Heat Pump Property,” which includes system purchase, installation fees, labor fees, and material costs. To claim these credits, homeowners should fill out and submit form 5695.

For most types of property, there isn’t a limit on the amount of credit available, and if the credit happens to be greater than taxes owed, it can be carried forward and applied to the next year’s tax return. Home Comfort Geo, a leader in geothermal heating and cooling, suggests speaking with a geothermal professional before making any home energy efficient improvements in order to lower the upfront cost of alternative energy installation.

For more energy efficient system installation rebate and incentive information, homeowners should visit Home Comfort Geo at http://homecomfortgeo.com/.

Geothermal systems provide energy independence for more homeowners

For years Dwight Nadig and his wife suffered through the cold winters in their York, Pa., ranch-style home, originally built in 1979.

'We have no access to natural gas in our neighborhood, so we had oil heat,' says Nadig. 'The price of oil has gotten extremely high and we found ourselves keeping the thermostat fairly low.'

Nadig started to investigate geothermal (or ground-source) heat pump systems to help them stay warm in the winter - without paying a lot of money on their oil bill. Quickly realizing the energy saving benefits, as well as the environmentally friendly aspects, he opted to install a system from ClimateMaster (www.climatemaster.com/residential).

'The geothermal saves us money and we can keep the house at a nearly constant temperature,' says Nadig, whose system went live about a year ago.
Nadig is just one of the many Americans who are replacing conventional oil, natural gas and electricity-based heating and cooling with geothermal heat pump systems, and the demand for these systems is only expected to grow, on a global scale, over the next decade.

'There are more than 1 million of these units in U.S. homes today, which means an increasing number of homeowners are recognizing the benefits of this system in controlling their energy bills for life, and essentially declaring their energy independence,' says Raj Hiremath, marketing director at ClimateMaster.

Geothermal Heating and Cooling Goes Mainstream in US

New reports show Geothermal to be, "One of the most mature and stable platforms of renewable energy usage…" High consumer satisfaction, green building growth, and programs to reduce first cost are rocketing geothermal heating and cooling into the US mainstream.

Geothermal heating and cooling technology has been an organized technology for more than 40 years, having been applied successfully for over 70 years. Geothermal systems are the most efficient air conditioning and heating technology available, providing premium comfort and remarkable equipment longevity, storm resiliency and impressive tangible benefits available only to those implementing the technology. Still, the technology has achieved only minor market penetration in the US, while the retrofit market in Canada and some European countries are favored with retrofit factors approaching 40% of equipment replaced /upgraded (Canadian GeoExchange.org).

In 2009, the US Stimulus Act provided tax incentives equal to 30% of the cost of geothermal HVAC installations for new construction, retrofits or upgrades. This incentive bolstered efforts to implement geothermal installations throughout the US. This has served to provide a base of well-trained tradesmen and professionals proficient in design, installation, and maintenance of geothermal HVAC systems, adding significantly to implementation of geothermal heating and cooling systems in new homes.

I think geothermal is cool, but you should mention that it only saves about 50% of carbon emissions, which makes it about the same as that not a bridge fuel natural gas.

Geothermal offers cost-effective alternative to volatile fuel prices and propane shortages

In the face of recent propane shortages and record high prices for the fuel – some rural areas reported deliveries as high as $8 per gallon – homeowners who rely on propane to heat their homes are beginning to consider more reliable, less costly alternatives. With increasing frequency, many are turning to geothermal, attracted by its ability to reduce heating and cooling costs by as much as 70 percent while relying on a clean, renewable and unlimited energy source.

The U.S. Environmental Protection Agency (EPA) says that geothermal heat pumps are the most energy efficient, environmentally clean and cost-effective space conditioning system available today. In fact, according to the Geothermal Exchange Organization (GEO), calculations from a major geothermal heat pump manufacturer show that at average prices during this year's blizzards, thermal energy from the earth saves 426 percent compared to fuel oil, 81 percent compared to natural gas, and an astounding 615 percent compared to propane.


In addition, a geothermal system does not require combustion and therefore produces none of the products associated with combustion, including carbon monoxide, which can negatively impact the air you breathe. Nor does it require a system to vent monoxide and other dangerous exhaust gases.

How Geothermal Heat Pumps Can Soar Like Solar

Not only can GHPs cut energy costs for heating and cooling by up to 80%, they can also provide other benefits such as essentially free hot water when in cooling mode, lower reliance on fossil fuels, and the elimination of above ground outdoor equipment. These advantages have earned GHPs a small but dedicated cult of true believers, but not broad market acceptance.

The world has not yet beaten a path to the GHP door. Instead, GHPs have a slim and only modestly growing market share. A study by Frost and Sullivan projects the market for GHPs in North American commercial buildings to grow at a 7.8% annual rate from 2012, 4.7% faster than the North American climate control market as a whole. An industry representative pointed me to a Navigant study which projects the world installed base to grow from 13.3 million tons to 36.2 million tons in 2020, see chart below.

The consumer guide to buying a heat pump

What on earth is a heat pump?

If you are at the start of your buying journey you might not be sure what a heat pump actually is. Read on and all will become clear.

A heat pump is a specialised product that will harness heat from the environment it is installed in, magnify the temperature interned, and transfer heat for use in the home. A heat pump is made up of an evaporator, a condenser and a compressor. It relies on the pressure/temperature relationship to manipulate the temperature of the refrigerant contained within. Heat is absorbed from the outside air, or ground, by the evaporator.The compressor serves to increase the pressure of the refrigerant, thus increasing its temperature. It is then brought inside and released by the condenser to heat the home. This process is repeated again and again.

What are the benefits of heat pumps?

There are many benefits to using heat pumps in your home. Whether you are green-minded, or not, they are certainly worth considering. Here is why!

According to Which, statistics from the Energy Savings Trust (EST) suggest that installing a heat pump can save you between £650 and £2000 per year on your heating bills. They really can be a great investment.
Not only do heat pumps provide a warmer, cosier environment, they can also provide you with your hot water.
Once installed, heat pumps tend to require very little maintenance. A good purchase may last you 20 years or more; affording you terrific return on your initial investment.
Some Air Source Heat Pump models (more on these later) double as an air conditioner when you want to cool your environment.
These great inventions generate significantly less carbon than other heating systems.
What are the main types of heat pumps?

There are two main types of heat pump:

The first installation option is a Ground Source Heat Pump (GSHP)
The second option is an Air Source Heat Pump (ASHP)
The main difference between these two types of heat pump is that the GSHP draws its heat from under the soil, and is installed below the ground, whilst the ASHP draws heat from the air, and is installed above the ground. An ASHP tends to be placed at the rear of a property or to the side, out of the way.

Choosing the right option for YOU

With winter coming on here in Ohio I will ask the usual fall question. Who on here uses ground source heat pump for winter heating and summer cooling? I really wanted one when I got my new furnace in 2013 but just could not justify the very long pay back period for the extra costs involved. If I ever build a house from scratch I would install one in a heartbeat, but doing a retro-fit is a whole different kettle of fish.

T - "...but doing a retro-fit is a whole different kettle of fish." As we've discussed before that's the basdic problem with most alts. It silly to just use the operation cost as justification without amortizing the capex. For both individual and commercial applications. Folks pointing to solar are some of the worse offenders.

A heat pump only works well if the system temperature is low. You need e.g. either underfloor heating or large radiators, this usually in combination with a improved insulation level of the building.

If you can not provide these basic parameters a HP would not be a good idea IMHO. Stay with NG.
