Geothermal Heat Pumps
How does a geothermal heat pump work?
- Glycol* is pumped through the exchange system, which consists of a series of pipes buried in the ground, at a temperature below the ground temperature. This temperature difference causes a transfer of heat energy from the ground to the glycol.
- In the heat pump evaporator, the glycol gives up the energy transferred from the ground to the refrigerant flowing through the refrigerator circuit, heating and boiling it.
- The refrigerant, now in vapour form is sucked by the compressor, considerably increasing its pressure and therefore its temperature.
- Then, this refrigerant, at high pressure and temperature goes to the condenser, where it cools and condenses giving up its heat to the water delivery system, which is heated.
- The hot water is circulated through the radiator system (floor heating, fan-coils, etc.), thus heating the home.
- Finally, the condensed refrigerant enters the expansion valve, which lowers its temperature and pressure in the evaporator so that it can again absorb heat captured by the glycol, thereby initiating a new cycle.
In short, a geothermal heat pump extracts natural heat from the ground and transfers it into our home.
Advantages of Geothermal Heat PumpsSignificant cost savings
What are the cost savings??????????
Local Natural Resource
No more worrying about the availability and price of fossil fuels, you'll never need them again. Your home's energy supply is secure from any spot in your own garden.
Integrated Climate-Control System
Geothermal heat pumps can provide heating in winter, cooling in summer and hot water all year round, so you get a full climate-control system with a single installation.
Not needing gas, oil tanks or other hazardous substances, completely does away with the potential risk inherent in the use of these products, such as intoxication, odours, pollution or explosion caused by leaks.
Minimal maintenance and long life
Although it may seem new, the technology used in geothermal heat pumps is widely known and completely reliable because it is identical to that used in the refrigerators we all have in our homes and know so well.
From the time of installation and commissioning, all you'll have to do is enjoy the comfortable environment at home all day.
No flames or smoke are generated
You do not need a chimney or to continuously ventilate the space, thus avoiding the cost, reliability and maintenance problems these systems can cause.
No visual impact
All heat pump components are buried or inside your home, giving it zero visual impact.
Reduction of CO2 emissions
There is growing concern about this issue; climate change is a fact and in recent years, the governments of the world's most influential countries have reached commitments aimed precisely at achieving a significant reduction in emissions.
Installing a geothermal heat pump contributes to achieving this common goal, since the technology fully respects the environment by drastically reducing CO2 emissions with respect to traditional technologies.
Independent from external environment conditions
Below 20 metres in depth, the ground temperature remains practically constant throughout the year, which means that geothermal heat pumps provide a higher efficiency than other types of heat pumps whose operating conditions depend on external environment conditions.
Geothermal Heat Pumps - All Year Round Climate Control SystemEcoforest geothermal heat pumps provide a comprehensive HVAC system; that is, heating in winter, cooling in summer and hot water all year round. This is one of the most important features of our heat pumps, and certainly a revolution in the field of climate-control.
With Ecoforest's heat pump technology, you will no longer need to invest in additional air conditioning to enjoy a pleasant ambient temperature during the warmer months. Changing from a hot environment to a cool one is as simple as pressing a button.
Additionally, all the hot water you need will be available all year round.
Winter During the winter, the ground temperature is greater than ambient temperature, so the pump draws heat from it and releases it inside of your home.
Summer In summer the opposite occurs, the ground is cooler than the air, so the geothermal pump extracts heat from the house and yields it to the ground, in exactly the same way it does to keep the inside of a refrigerator cooler than the outside temperature.
You can choose between two methods of cooling:
For very warm areas that require greater cooling, the heat pump compressor starts and the direction of flow of the refrigerant in the refrigerant circuit is reversed, so the geothermal heat pump becomes an efficient air conditioning system for your home.
The efficiency of geothermal heat pump in the active cooling mode is much higher than in traditional air conditioning systems.
If you live in a temperate zone where excessively high temperatures do not occur during the warmer months, passive cooling is your best choice. Here Ecoforest geothermal pumps are equipped with an additional heat exchanger in which the ground-cooled glycol from the extraction system cools the water in the radiator system. On flowing through the underfloor radiation or fan-coils, the cool water produces the desired temperature drop inside the home, and uses less energy than a pair of light bulbs to do so.
