How to Install a Ground Source Heat Pump
A ground source heat pump is the new way of creating green heat which will save you a lot of money in a rather short period of time. The idea of the ground source heat pump is that the heat in your home is being generated by the heat of the earth. This makes a ground source heat pump a completely green way of supplying heat to your home. The problem with a ground source heat pump is that is a very technical addition to your home. A ground source heat pump is very hard to install and should only be done so by professionals in the field. The article that follows will provide you wish an understanding of what is needed to install a ground source heat pump and how it is installed.
Step 1 - Selecting a Location
In order for a ground source heat pump to work correctly it needs to be placed in the right area of your property. In some cases a ground survey team will come out to test the soil and the temperature of the ground. For the ground source heat pump to do its job it has to be placed perfectly. These tests will yield proper information in order to determine how deep the ground will have to be dug. The depth of the ground will also determine how you will layout the polyethylene pipe.
Step 2 - Digging the Hole
The hole being dug depends on the circumstances of your property. The hole can either be dug to a depth of 4 to 6 feet if the polyethylene pipe is to be placed horizontally. If the pipe will be placed vertically then it can be 100-feet deep to as much as 400-feet deep. The decision on depth will be made by the professional and the tests conducted.
Step 3 - Air Handler
A ground source heat pump is not much use without an air handler. This is installed into the home and is connected to the existed duct work. The purpose of this device is to blow the air from the polyethylene pipe into the home and also to remove it and to circulate it.
Step 4 - Polyethylene Pipe
This is the bread and butter of the ground source heat pump system. The pipe is coiled and placed in the ground in the manner that is decided by the professional. It is connected to the air handler box in the home and then filled with a non-hazardous blend of water and anti-freeze. The mixture is pushed through the polyethylene pipe by the air handler. As this mixture makes its way through the pipe it is either heated or cooled by the temperature of the ground. If it is summer, then the ground will cool the water and then produced cool air via radiators. The reverse is also true in the winter where there the hot air is circulated out and cooled by the ground then released back into the air.
