What is Geothermal Energy and Why Should I be Interested?

Thursday, April 12th, 2012

Geothermal heating and cooling systems are nothing new. They have been around for quite some time. But until recently, these highly efficient systems had been flying under the radar.

What is Geothermal Energy?

Geothermal heating and cooling systems are incredibly efficient because they utilize geothermal energy, which is energy stored in the ground. You see, the ground absorbs the sun’s energy everyday, storing it just a few feet below the surface. A Geothermal heat pump extracts this energy and uses it to either heat or cool your home, depending on the season.

Installing a Geothermal Heating and Cooling Systems

First, there are several factors to consider:

-The amount of property you own

-Will this system be a retrofit for your home or a new construction

Types of Geothermal Heating and Cooling Systems

-Horizontal (Closed-Loop Systems): Generally the most cost-effective option for residential use, horizontal geothermal heat pumps cut down on installation costs by utilizing a Slinky method of looping pipes in a shorter trench (5 feet deep and 2 feet wide).

-Vertical (Closed-Loop Systems): Most often used for large commercial buildings and schools, vertical geothermal heat pumps are perfect for areas where the land required for horizontal loops would be prohibitive. Vertical GHPs minimize the disturbance of existing landscape. Instead of long trenches, vertical systems utilize deep holes (4 inches in diameter and 100-400 feet deep).

-Pong/Lake (Closed-Loop Systems): If there is a body of water close by, this may be the most cost-effective option for you! A supply line pipe is run underground from the building to the water and coiled into circles at least eight feet under the surface of the water (this prevents freezing from becoming an issue).

-Open-Loop System: An open-loop geothermal heat pump utilizes well or surface body water as the heat exchange fluid throughout the GHP system. Once the water fully circulates through the system, it returns to the ground through the well, a recharge well, or surface discharge.

-Hybrid System: Hybrid geothermal heat pumps utilize several geothermal resources or a combination of geothermal sources and outdoor air. These types of systems are designed for areas where cooling needs are significantly larger than heating needs.

Benefits of Geothermal Heating and Cooling Systems

-Geothermal Energy is renewable

-Geothermal energy reduces acid rain created by the burning of fossil fuels by 97%

-Geothermal Heating and Cooling is incredibly efficient and cost-effective

-With very few moving parts, Geothermal heating and cooling systems are incredibly quiet and make little to no noise inside and outside the home.

-Underground piping often carries warranties of 25–50 years, while the heat pumps, themselves, often last 20 years or more.

Heat Pump System Design and Function

Friday, April 6th, 2012

Heat pump system design – for both air source and ground source heat pumps – is incredibly simple, requiring just a few key components to deliver desirable results. Both systems make use of renewable sources of energy to provide complete heating and cooling solutions.

Heat Pump System Main Components

  • Compressor
  • Fan
  • Copper Tubing
  • High Pressure Safety Switch
  • Reversing Valve
  • Defrost Control
  • Protective Wire Meshing

Heat Pump as a Primary Cooling System: The heat pump is a very efficient and reliable cooling system and can provide cooling to a building via its own operations without the need for additional cooling systems, such as CAV and VAV.

Heat Pump as a Primary Heating System: By changing the direction of the refrigerant flow, you can transform your heat pump into a heating system.

Benefits of Heat Pump Systems

  1. 1. Since heat pumps do not require traditional style boiler or chiller to perform both heating and cooling functions, these systems tend to cost less.
  2. 2. Heat pump systems are incredibly efficient, which also helps to save you more money.Heat pump efficiency is measured with two distinct ratings. While in the cooling mode, heat pumps receive a Seasonal Energy Efficiency Ratio or SEER number. SEER is like gas mileage. The higher the gas mileage or SEER, the more efficient the automobile or system is. Most new heat pumps rate between 13.0 and 19.0 SEER. While in the heating mode, heat pumps also receive a Heating Seasonal Performance Factor or HSPF rating. Again, the higher the number, the more efficiently the system works. Most new units have ratings between 7.7 and 9.0 HSPF.

Types of Heating Systems

Friday, March 2nd, 2012

There are numerous central heating systems on the market today, most of which comprise of a boiler, radiator, and pipework. But which central heating system is best for you, your home, your needs, and, most importantly, your budget?

The right heating system is crucial in the battle to keep your home at a comfortable temperature, while still maintaining energy efficiency.

Two Main Types of Central Heating Systems

1. Pumped/Vented: These are the most common types of central heating systems. A pumped/vented Central Heating System has a feed and expansion tank, which supplies your home with hot water and provides the radiators with heat. The tank is designed to compensate for any water expansion that is caused by the heating process.

2. Sealed: With sealed heating systems, no water tank is needed. The whole system is sealed and unvented. The benefits of a sealed system include: no risk of freezing pipes in the loft; no maintenance work on the tank or pipes that would be in the loft in a pumped/vented system; reduces the risk of leaking; reduced risk of airlocks, corrosion and sludge as there isn’t a chance of air being drawn down into the system through open vents as the system is sealed; and it can be flushed out under pressure if needed by the mains water supply.

No matter which central heating system you choose, you will not be disappointed. These heating units are worth the money. They are cheaper to run. They offer all around control. And they are incredibly efficient.

Geothermal Heat Pump Brings Great Savings

Friday, February 24th, 2012

Geothermal heat pumps (GHPs) are not only incredibly efficient at heating and cooling your home, but they also save you money in the process. How do GHPs accomplish this? Well, as we already said, they are extremely efficient. GHPs use up to 44% less energy than air-source heat pumps and as much as 72% less energy than other conventional heating and cooling solutions. And that leads to more money in your pocket!

What Makes Geothermal Heat Pumps So Energy Efficient?

While traditional air-source pumps draw heat from the outside air, geothermal pumps work by taking heat from the Earth’s surface. This proves to be much more energy efficient, because while the temperature of the outside air is in constant flux, the temperature below the Earth’s surface remains at a constant 50°F.

Additional Benefits of Geothermal Heat Pumps

• Geothermal Heat Pumps are quieter than traditional heating and cooling units.

• GHPs’ design flexibility allows them to be installed as part of newly-constructed homes or in retrofit situations.

• Geothermal Heat Pump hardware takes up less room than other systems, freeing up space in your home.

• These heat pumps are incredibly durable and last longer than traditional systems. The underground piping often carries warranties of 25–50 years, while the heat pumps, themselves, often last 20 years or more.

• GHPs require less maintenance than other heating and cooling systems.

• And if the geothermal pump has a two-speed compressor and variable fans, you can enjoy even more cost-savings on your energy bills.

Benefits of Geothermal Heat Pumps

Friday, February 3rd, 2012

Did you know that the Earth absorbs 47% of the sun’s energy and stores that energy in the ground, which remains at a relatively constant 50 °F? Well, it does. And what if I told you that you could harness that energy to heat and cool your home? Well, you can!

Geothermal heat pumps (GHPs) tap into that energy stored beneath the Earth’s surface and utilize it to heat your home in the winter (and cool your home in the summer). During the colder months, GHPs draw energy from the ground and transfer that heat energy into your home. During the warmer months of the year, the system removes heat from the home and dumps it into the cooler earth. This transfer of heat energy is done through a series of pipes buried in the ground, or sunk in a pond, or by using well water.

Benefits of GHPs

Energy Efficient: Because a geothermal system simply moves heat instead of burning a fossil fuel to generate it, it’s more energy-efficient. In fact, GHPs use 25%–50% less electricity than conventional heating or cooling systems.

According to the Environmental Protection Agency (EPA), GHPs can reduce energy consumption up to 44% compared to air-source heat pumps and up to 72% compared to electric resistance heating with standard air-conditioning equipment

Humidity Control: GHPs improve humidity control by maintaining about 50% relative indoor humidity.

Zone Space Conditioning: GHP systems allow different parts of your home to be heated or cooled to different temperatures.

Quite: With very few moving parts, GHPs are incredibly quiet and make little to no noise inside and outside the home.

Long Lasting: Underground piping often carries warranties of 25–50 years, while the heat pumps, themselves, often last 20 years or more.

How Geothermal Heat Pumps Work

Friday, January 13th, 2012

We have been talking about geothermal heat pumps, also known as ground source heat pumps, for several weeks now. But today we have decided to give you a better understanding of exactly how these mysterious machines work.

Geothermal heat pumps do not create heat like traditional heating systems (furnace). Instead, they MOVE heat. Using a substance called refrigerant, heat pumps transfer heat from one place to another – from outside to inside a home in the winter and vice versa in the summer. When compressed, refrigerant is a high temperature, high-pressure liquid. If allowed to expand, it turns into a low temperature, low pressure gas. This refrigerant travels through a series of pipes, called a loop, installed below the earth’s surface (which remains at a fairly constant temperature). During its journey, refrigerant absorbs heat and transferring it inside the home. This heat is then circulated through your home’s ductwork. As we mentioned before, this process is reversed in the summer.

Studies have shown that approximately 70% of the energy used in a geothermal heat pump is renewable energy from the ground, making these systems the most energy efficient heating and cooling systems around. Using a geothermal heat pump can reduce your energy bills by as much as 40%. And since they are mechanically simple with outside components below ground, maintenance costs are reduced as well.

If we didn’t have your attention before, we sure do now!

The types of geothermal heat pumps include:

Horizontal (Closed-Loop System)

Typically used for residential projects, horizontal geothermal heat pumps require sufficient land and trenches at least 4 feet deep. The most common layouts either use two pipes, one buried at six feet, and the other at four feet, or two pipes placed side-by-side at five feet in the ground in a two-foot wide trench.

Vertical (Closed-Loop System)

This type of GHP is typically used for commercial buildings and schools. For a vertical system, holes (approximately four inches in diameter) are drilled about 20 feet apart and 100–400 feet deep. . Into these holes go two pipes that are connected at the bottom with a U-bend to form a loop. The vertical loops are connected with horizontal pipe (i.e., manifold), placed in trenches, and connected to the heat pump in the building.

Pond/Lake (Closed-Loop System)

Perhaps the lowest cost option (if your site has a sufficient body of water nearby). A supply line pipe is run underground from the building to the water and coiled into circles at least eight feet under the surface to prevent freezing. The coils should only be placed in a water source that meets minimum volume, depth, and quality criteria.

Open-Loop System

This system uses well or surface body water as the heat exchange fluid, circulating directly through the GHP system. Once it has circulated through the system, the water returns to the ground through the well, a recharge well, or surface discharge. This option is obviously practical only where there is an adequate supply of relatively clean water, and all local codes and regulations regarding groundwater discharge are met.

Air Heat Pumps – Major Energy Savers For Your Heating And Cooling Needs

Wednesday, December 28th, 2011

Heat pumps can provide an energy-efficient substitute for furnaces and air conditioners in moderate heating and cooling climates. A pumping system, similar to a refrigerator, utilizes electricity to transfer heat from a cold area to a warm one, or vice versa. This means that during the winter, heat pumps transfer heat from the cool outdoors into your home and during the summer, these pumps move excess heat from inside your home to the outdoors.

Since these air-based heat pumps are only moving heat and not actually generating it, they can cut your total electricity use by as much as 40%.

These high efficiency pumps also de-humidify more effectively than standard central air conditioning systems. This means that you will use far less energy while also achieving a more comfortable home.

The only downfall of these systems is that they are not suitable for areas of extreme high or low temperatures. In such circumstances, the efficiency of these heat pumps drops dramatically. Still, there are certain models that are up for the challenge, like geothermal heat pumps. These systems transfer heat between your home and the earth (not the air), taking full advantage of the relatively continual ground temperature.

While geothermal heat pumps are expensive to install, they traditionally have lower operating costs.
