You’re Guide to DIY Geothermal Heating and Cooling
The adoption of ground source heat pumps are not normally for the DIY-type of works, but if you must then you must keep in mind that there are a number of things to be considered for the installation to really work. For example, you have to take into consideration the area of the dwelling or the property. It would be best as well to survey the area, including land elevation and the land area including the type of basement used. This is important for the installation of some geothermal HVAC systems since holes may be excavated. Other than these things, it is important as well to have a rough idea of what DIY geothermal heating and cooling is. This is important, and you can liken this to the setting of objectives, and what not to do.
Here’s a short background on geothermal cooling and heating for homes. The system is actually made up of either the closed or the open loop system. For most applications, the choice is the closed loop where pipes are buried horizontally at least 4 feet. The pipes are filled with a water solution, and this acts as the heat exchanger. During winter, the fluid contained in the pipes gets the heat from the Earth and transfers this to the building. And during summer, the process is the reverse as excess heat is taken out of the building. This is one cost-effective solution in trying to cool and heat the building when it’s needed.

Now this can be yours too, and this can be installed with minimal supervision coming from the experts. Just make sure that you have the best geothermal DIY kit, the other tools and materials needed and the rules for installation which are listed below. Speaking of materials and tools that are needed, for this project you will need back hoe, hole digger, adjustable pipe wrench, wire cutters, electrical tape and wire caps. Assuming that you have already ordered your geothermal pipe kit, just follow the listed step-by-step guide:
1. Dig the holes where the pipes. The pipes can be installed vertically or horizontally. Use digging tools like a back hoe which can be rented.
2. Once the hole is ready, prepare the pipes that will be laid. Make sure that the laying of pipes and hoses is in accordance with the chosen system. Under the horizontal system, the pipes and hoses will be laid with a return connection to your home.
3. Cut off the main power before replacing the pump. If you have an existing pump, replace this with the new one. Just cut the new wires and connect the new ones from the GHP. Correctly match the ground and hot wires. The wires are usually color-coded- the green or copper for the ground and the black and the red for the hot wires.
4. Once wires are paired, create a connection from the loop to the pump, using the same connection rules.
5. Finish this by starting the pump and by opening the pump valve. The pipes should contain a mixture of water and anti-freeze for this to work.
Specific instructions may be needed depending on the provider of the DIY geothermal heat pump. But for the basic steps in the installation of geothermal, the provided steps below clearly explain it.
