An investment needs to be made to install a heating and cooling system whether it is a conventional or geothermal system.
Geothermal heat pumps are the best heating and cooling option for homeowners looking to build a new home. The upfront costs for a new construction geothermal system are usually less, and the initial costs are dispersed over the life of the mortgage in the monthly payment.
The slight increases in mortgage costs by upgrading to the more efficient and long lifespan of a geothermal system are typically offset by the decreased operating costs providing a net positive cash flow from the moment you occupy your new home.
Geothermal products are not only one of the most efficient and energy-saving options, they are also one of the best environmentally-friendly choices you can make for your new home and the planet.
In the new construction phase a home is a fresh slate with no patio’s, retaining walls, or decks in place yet, therefore, it is easier to design the system to best fit your heating and cooling needs right from the start. Landscape items can easily be designed and installed around the geothermal installation since any piping begins four feet below the surface of the ground. At this point, the site is already disturbed and landscaping is scheduled to be complete long after the installation.
Since the geothermal boreholes and pipes are 4′ below grade, they can be placed almost anywhere as long as they meet setback requirements for drainage, septic systems/sewer lines and wells/water lines. There are usually many alternatives for borehole placement, and they can even go under future driveways.
Starting at the point of new construction also gives the opportunity to select the optimum insulation materials for the geothermal so the equipment can be right-sized for the thermal envelop of the house creating the most savings possible. The better the thermal envelop of the house, the lower the initial cost to install geothermal.
Some other advantages to installing a geothermal system during new construction:
- The ducts are designed and installed to support the geothermal system.
- Radiant floor systems can be considered and integrated into the construction plans, which is much more cost effective than retrofitting a home for radiant floor heat.
- Choices for back-up heat, domestic hot water and the use of generators can be considered and planned to be consistent with the geothermal system and the owner’s wants and needs.
- Planning for your geothermal system up front in the design process is very cost effective.
- Most people who are interested in geothermal heating systems for their home already have a heating system in place. While installing any system is easiest in a brand new house, there are options available with geothermal retrofits to adapt your current system no matter which type it may be.
- Retrofit systems simply swap out the inside unit, remove the outside exchanger (aesthetics improvement!) and hook up to existing ductwork in the home.
- Additionally, pipes will be installed underground and will require some digging in your yard, but horizontal loops only need trenches of about 2 feet wide. Vertical loops require even less space and disturbance to your lawn. Geothermal system installations do not cause permanent changes to lawn or yard quality or any problems with trees, grass, or other plants. Your grass will quickly grow in from the initial installation, and you should notice no differences in your yard.
- How much you will save replacing your current system with a geothermal system varies depending on how much you are currently spending on heating your house and how large a system you need to heat your home. Typical savings range from 40% to 70%!
- Green Hill geothermal can apply our savings calculator on your existing system verse the new geothermal system, which will determine your savings whether you purchase your system outright or if you pay over time. In either case, you will experience instant savings! Remember, geothermal heat is renewable!
- What should I do to get my house ready for a geothermal retrofit?
- Selection of a geothermal heat pump that has the capacity to both heat and cool your home is very important, and one of the things that factors into that calculation is how energy efficient your house is. The more energy efficient your house, the smaller of a heat pump you will need, so it is an important first step before beginning the retrofitting process.
- A professional energy audit performed on you home will determine the appropriate unit size and recommend any steps that can be taken to reduce the unit size and save even more money.
- No matter what system you currently have in place, a geothermal heating and cooling system is a great way to make your home more environmentally friendly. Be sure to talk to our geothermal experts to find out if a geothermal retrofit is the right option for you.
Horizontal Geothermal System
At Green Hill Geothermal, we are experts who do the work in-house from design through installation. Horizontal Geothermal is just as effective and efficient as Vertical Wells but saves thousands of dollars in installation, and this is important especially in rural areas. Green Hill does all horizontal trenching in house saving the homeowner expense.
Often when installing your new Geothermal Heating and Cooling system, the contractor has no choice but to utilize subcontractors for the trenching of Horizontal Geothermal systems and drilling for Vertical Well systems. While drilling requires a very specialized type of equipment, trenching requires less specialized equipment.
A contractor that is able to perform this type of installation with in house resources, reduces cost to their clients by eliminating the mark up associated with utilizing subcontractors to help with portions of the installation. We perform all of our own trenching for Horizontal Geothermal installations. Green Hill has on staff the necessary tradesmen, that understand the Geothermal installation process, and can save our clients time and money as a result.
We also do all horizontal piping for vertically drilled systems. Most HVAC contractors get the driller to take care of this portion of the installation which is not their specialty, but with us you’re getting a guaranteed product from the company that actually performs all of the work.
