How we can help you

iWolf Technology Services installs geothermal heating, cooling and electrical power generation systems for residential and commercial applications.

The constant temperature of the shallow ground can be used to create the most energy efficient climate control systems for air temperature control, hot water services, floor radiator heating, wall radiator heating, swimming pools, spas and generating electrical power. Geothermal Energy systems deliver increased property value, lower electricity bills and a higher star rating.

Geothermal ground source heat pumps (GSHPs) are used to transfer natural heat from the surrounding earth to the inside of a building, delivering energy efficient space and water heating. The same technology is used in reverse to cool by transferring the heat from the building into the shallow earth below.

A typical Geothermal system incorporates a heat pump, ground loop and a heat distribution network of forced air, or wall and under floor heating radiators.  A ground loop is a series of closed loop pipes submerged in a bore-hole or a horizontal trench through which water is passed.

In “Heating Mode” the water is forced through the ground loop to draw heat from the ground. The heat pump then draws heat into the structure through a custom air conditioning unit or into a water heating unit to deliver heat energy.

In “Cooling Mode” the heat pump serves to remove heat from the structure and transfers it to the earth. Globally, geothermal heat pumps play a key role in reducing carbon emissions and greenhouse gases normally associated with heating and cooling, water and air in residential buildings.

 

For Residential Use

Suitable for integration into new homes or incorporated into structures, geothermal energy can be used for a huge range of climate control systems. A good Geothermal Energy Solution can cut up to 78% off your total energy bill.

iWolf’s energy efficient geothermal energy solutions provide affordable residential heating and cooling solutions that subsidises against ever increasing electricity prices while significantly lowering energy bills, increasing property value, improve life style and reduce carbon emissions.

What are the benefits of Geothermal Heating and Cooling?

1)    Saves you money.

By tapping into the natural heat contained in the earth, geothermal heating and cooling solutions are an efficient low-energy technology that can save you up to 80% on energy bills. Regardless of where you live the underground temperature remains fairly constant all year round even though the outdoor temperature may change greatly. Geothermal systems exploit this constant renewable energy source for heating and cooling. The more domestic services your geothermal system drive in your home, the greater the return on investment.

 

2)    Reliability and Performance. Proven, tried and true.

Geothermal energy is a relentlessly available, emissions free, renewable energy source with huge benefits to our environmental while saving you money. Geothermal energy has endured the test of time and is considered one of the most reliable renewable energy supplies. Solar enhanced geothermal solutions can deliver efficiency up to 81% in heating and cooling, and up to 87% in water heating. Geothermal coefficients of performance (COP’s) rate from 3.5 up to 5.0 in space heating and cooling systems. These systems reduce costs by approximately 32% when cooling and heating costs by 78% as compared to electric climate control systems. Geothermal energy is the most efficient way to heat and cooling buildings in almost any area. Because of its direct and exclusive design, our systems offer amazing reliability, marginal maintenance and long life cycle.

 

3)    Suitable for both New home design, retrofit or as an add-on

Many homes are unique and require a tailored solution to meet your exact standards. With our geothermal systems a roof-mounted air conditioning system is no longer required add further cosmetic benefits when designing or renovating your home. Geothermal heating and cooling systems can be mounted almost anywhere, out of sight and out of mind.

 

iWolf’s Geothermal Energy specialists will provide you with all the expertise and guidance you need.

 

4)    Cleaner and quieter comfort

With an iWolf geothermal energy system you will enjoy cleaner air and a quieter home for you and your family. Our system’s offer an efficient technology that cools air and water in your home without generating carbon dioxide and greenhouse gas emissions.

It is also very quiet compared to the noise of typical air conditioners and heat pumps.

 

5)    One system has many uses

The same unit can be used for heating and cooling of living space, domestic water, swimming pools, spas, cool rooms and Cellars, all year around.

 

6)    Compact and convenient

iWolf geothermal solutions feature a small system footprint and uses up to 80% less physical space than other legacy systems and requires no ventilation what so ever.  They are easy to integrate into any building or yard.

 

7)    Can be used anywhere

iWolfs geothermal systems are designed to work anywhere perfectly regardless of the climate.

Generating Electricity from Geothermal Energy

Geothermal Heating and Cooling Systems for commercial sites and residential homes use an entirely different type of technology to that used when extracting geothermal energy for purpose of electricity generation.

There are several different main stream technologies used in geothermal plants i.e. Flash steam, Dry steam and Binary cycle. What they all have in common is that they use steam turbines to generate electricity. This method is widely used for generating electricity from other renewable energy sources.

The next step in the cycle is cooling the fluid and sending it back to the heat source. Heating boilers are not used in geothermal steam power plants and no heating fuel is required. Production wells are used to convert water into stream and hot water which flows from the reservoirs into the power plant. Injection wells are used to draw the water up from the production wells and returns it to the geothermal reservoir where it will absorb more thermal energy (heat) to generate more electricity. Most geothermal power plants extract water in its vapour or liquid form from the reservoirs where the temperature  ranges from 100-320°C.

 

Dry Steam Geothermal Power Plants

Referred to as “Dry Steam” because the water is extracted from the underground reservoirs, geothermal steam of more than 150°C is directed through the production wells and directly to the turbine.

Geothermal reservoirs such as geysers can be exploited by geothermal dry steam power plants but these are rare. Dry steam is the oldest type of geothermal power plant first constructed in Larderello, Italy, in 1904.

 

Flash Steam Geothermal Power Plants

The term “Flash Steam” refers a process where high-pressure hot water is vaporised into steam inside a tank by lowering the pressure. The steam is then used to drive turbines. Today, flash steam is most common type of power plant.

 

Geothermal Binary Cycle Power Plants

Binary cycle power plants have a huge advantage over flash steam and dry steam power plants because the water temperature can be as low as 57.5°C. Using a binary fluid mixture with a much lower boiling temperature than regular water, the thermal energy flashes the fluid mixture into steam which is in turn used to generate electricity via a turbine. Water from the geothermal reservoirs comes through the production wells but never in direct contact with the working fluid. After its heat energy is transferred to the working fluid via the heat exchanger the water is sent back to the reservoir through the injection wells where the cycle starts again. Geothermal Binary Cycle power plants have a low thermal efficiency rating of only 10-13%. Nonetheless, these power plants allow us to harness geothermal energy from reservoirs that dry or flash steam power plants can not.

 

Cogeneration Power Plants (Combined Heat and Power)

Depending on the type of geothermal power plant, its location and various other factors, cogeneration thermal efficiency rates 10-23%. However its low efficiency rating does not impact on the plants operational costs as it would with fuel powered plants. While electricity generation does suffer from low thermal efficiency rates, the by-products i.e. exhaust heat and warm water also has many useful purposes. By taking advantage of the thermal energy’s by-products, overall energy efficiency is increased.
