Geothermal with a heat pump and solar could get you off the grid or nearly off. More San Francisco Bay Area residents are opting for geothermal with Earthlinked because of the smaller lots in the more populated areas and those with some room around their property love the refrigerant component of the heat pump where the installation costs can be significantly less than the water based heat pump.
For our unique South Bay climate, heat pumps offer an energy-efficient alternative to furnaces and air conditioners. During the summer heat pumps operate like a normal air conditioner. They transfer heat from the home to the atmosphere.
During the heating season, this process is reversed and the heat pump moves heat from the cool outdoors into your warm house. Because they transfer heat rather than generate heat, heat pumps can provide significant savings over other forms of heat.
The most common type of heat pump is the air-source heat pump, which transfers heat between your house and the outside air. If you heat with electricity, a heat pump can trim the amount of electricity you use for heating by as much as 50%-75%. High-efficiency heat pumps also dehumidify better than standard central air conditioners, resulting in less energy usage and more cooling comfort in summer months.
Ground Source Heat Pumps and Geothermal
Much like the heat pump mentioned above the ground source heat pump uses the ground instead of the atmosphere to transfer heat.
In the western US as with many other areas in the world, the heat is held in the ground nearer to the surface, which may make geothermal heating more desirable. It is important to note that just about wherever you are located ground sourced heat pump coupled with a geothermal system and solar energy can dramatically reduce or even eliminate dependence on other energy sources.
The process requires drilling into the earth's surface to tap into the earth's heat for the ground sourced heat pump to do its intended job. To have this installed at your home or place of business it may mean that the surrounding landscaping or even paved areas may need to be dug up to get the geothermal system installed. This is all able to be reconstructed after the installation.
For a limited time the Federal Government is offering a 30% tax credit (without any cap) on geothermal heat pump cooling and heating systems. With the current government and economy it is unclear how long rebates and tax credits will remain available to the public. The 30% credit with no cap is very desirable, and this is why people are choosing to have this installed this year.
Geothermal heating is a fairly involved process, it is an investment and it also that requires a site visit and planning. For more information about the process, please give us a call to learn more at
