4 Things to Consider When Building a Ground Source Heat Pump
It is no wonder that you are interested in a ground source heat pump in this new world of green energy and heat efficiency and the preservation of natural resources. The purpose of a ground source heat pump is to use the heat generated by the earth to heat and cool your home. The article that follows will provide you with several things you need to know about a ground source heat pump before building one.
1. Independence from Non-renewable Resources
A ground source heat pump is used to heat and cool your home by using the constant temperature of the Earth. The ground source heat pump can cool your home, heat it and also heat your water. It is attached to the electrical system, but frees you from having to use gasoline or oil in your home. Coils placed in the ground trap the heat of the ground and use it to provide heat in the winter and lower temperatures in the summer.
2. Know the Expense
You need to understand the costs associated with installing a ground source heat pump on your property. You can install an air conditioner yourself, for a few hundred dollars, and even a central heat and air system for under a thousand (depending on the size of your home). A ground source heat pump can cost anywhere from $7,500 to over $20,000, depending on your location. The price is due to the fact that a professional has to be used, proper permits need to be applied for and excavation has to be done. There is a lot of work involved with building a ground source heat pump system. The investment in this type of system is paid over its life in the savings you will see. It will also increase the value of your home.
3. Space and Size Restrictions
Prior to considering a ground source heat pump, check with the zoning office that services your neighborhood. You need to know where gas and water lines are, as well as any underground phone lines or fiber optics. You also need to know how deep a borehole is allowed to be, as a ground source heat pump may have to be installed deep underground. This depends on your location, as the ground needs to maintain a constant temperature. If you live in a suburban neighborhood, you may be prohibited from installing a ground source heat pump, due to the proximity of the homes. If you are permitted to have one, the size of the unit may be restricted, which can hinder or completely negate the purpose of the device.
4. Maintenance and Repair
A ground source heat pump is made to be worry-free and requires very little maintenance, but they can still malfunction. If this happens, you will need to excavate the entire area and troubleshoot the device. Repair and troubleshooting a ground source heat pump can cost hundreds of dollars. This cost can also rise considerably, depending on the problem with the unit. The coils that conduct the heat are rather inexpensive but the main power unit has a big price tag.
