Currently, DIY geothermal heating and cooling systems are gaining popularity throughout Canada and the USA. Now ground source heat pumps are able to deliver incredible level of COP (Coefficient of Performance) of 5 times or more.
This means, you will receive higher return on your investment much faster. However, geothermal heating systems are considered as the popular green energy option available on the market for both northern and southern climates. These systems are properly engineered to deliver both heating and cooling benefits while offering a greater level of flexibility to homeowners.
Likewise all available solar systems, geothermal heating kits take complete advantage of the solar energy. Generally, these systems do it indirectly by harvesting solar energy which has been absorbed by the earth throughout the year.
The topmost surface of the earth freezes in cold climate conditions. Just below the earth’s top surface, there’s huge availability of heat energy which needs to be pulled out and transferred into a home or business.
In fact, a geothermal heat pump works like an air conditioner and it works in both ways. This heat pump helps in eliminating heat from the earth during the winter and transfers heat energy to the house. Again, the heat pump pulls out the heat energy from the house and transfers it back to the earth during summer.
This DIY geothermal heating and cooling system utilizes much less energy than it supplies and eliminates. It’s known as the Coefficient of Performance or COP. Every heat pump comes with energy rating that explains this ratio.
Most advanced heat pumps can produce around four times of the energy than they use. If the compressor uses 1 Kw energy for its operation, it can create 4 Kw free energy. In this case, the COP will be 4 which results in 66% less energy usage for heating and cooling. For a COP of 5 or more, you will receive energy savings of 75%.
Generally, a geothermal system collects heat from the ground through interconnected piping series and the heat transfer liquid flowing throughout the piping. If there’s an increase in piping and diameter, the system will get more contact with the soil and will be able to transfer more amount of energy.
The piping required for a geothermal system depends on the size of the heat pump and the condition of the soil. Moreover, the heat pump size is based on the furnace size. To calculate the amount of heat, it’s necessary to know the maximum amount of heating and cooling needed during the average coldest and hottest days. It’s otherwise known as the heat energy and is rated in KW or BTU or as Tons. However, a 4 ton heat pump produces 48,000 BTU or 14 Kw energy.
You will find residential heat pumps ranging from 2-5 tons on the market. It will depend on the square footage of the home, location, the insulation capability, window and many other important things. Nowadays homes are built to the exact standards and you need to choose the right size heat pump as per the square footage and geographic location.
