The Benefits of Geothermal Systems in Winter

Heat pumps are the most common ways to get warmth for homes – but they do come with a caution. As a heat pump should draw off heat from the outdoor air to provide heat to the indoors, the deep cold temperature will cut into the energy efficiency of the heat pump.
 
However, this is where geothermal systems can help you. Usually, geothermal heat pumps or the ground source heat pumps are one of the most reliable heating systems to be utilized year round. Regardless of the frigid temperature in the outdoor, they can offer a level of savings that can surpass the standard heat pumps and furnaces both electric and gas.

Though geothermal heat pumps make up a very certain niche in the HVAC industry, there are still a plenty of choices to choose from. Therefore, you should make a decision according to your property.

There are three major types of geothermal systems that are discussed below:

1. Closed Loop Systems –

Closed loop systems use a length of tubing like plastic that is circulated with coiled and antifreeze deep underground. A special device known as a heat ex-changer conducts heat derived from the loop to the refrigerant in the above-ground unit – which again controls the temperature of your home. In fact, the closed loop systems can be installed in different configurations like vertical, horizontal, in pond or lake.

2. Open Loop Systems –

Open loop systems use surface body or well water to control temperature instead of antifreeze. Then, the water is circulated throughout the system; and run through a heat exchanger like the same way in a closed loop system. After that, it is discharged in a different well.

3. Hybrid Systems –

Hybrid systems utilize a combination of geothermal resources available. Though these systems vary from one installation to other, there is no standardized description.

These are all about three types of geothermal systems available for use. Now take a look at how geothermal pumps work well in winter:

How geothermal systems work in winter?

A geothermal heat pump draws heat from the outside, like the same way as a standard heat pump. The key difference is where exactly the outside of the house the pumps pull the heat.

A geothermal system uses underground loop filled with a solution of water and antifreeze to draw heat – again passes through a heat exchanger to send the heat to the refrigerant and circulates throughout the indoor parts.

Generally, the loops are located deep enough so that the frost on the ground in winter doesn’t reach there. Nevertheless the amount of cold on the ground during the winter, the pump maintains an almost constant temperature between 45°F and 50°F. This is only possible for the heat radiation from the earth’s core.
The resultant amount is more than enough to allow the geothermal heat pump work without additional hassle. In summer, it’s cool enough to ensure the easy deposition of heat energy when the geothermal systems are in cooling mode. This way, you can enjoy efficient home comfort year round.

Top Reasons Why You Should Consider Using Geothermal Systems

Image
Geothermal systems are not as popular as solar thermal systems but they are an effective green energy option widely used in the USA and Canada these days. These ground source heat pumps tap into the free solar energy just like their solar counterparts, but indirectly by drawing what has already been absorbed in the earth’s surface over time. The performance of the geothermal systems will never be a problem as they are powered by underground temperatures which keep stable and don’t fall drastically even in the colder climate conditions as temperatures above the ground often do.    Geothermal systems function as a 2-way air conditioner, serving your heating and cooling needs in a single system. The smart design of these systems allows them to pull heat from the earth through a series of interconnected pipes underground filled with a heat transfer fluid (an antifreeze solution) in the winter directing it to the house. However, they work opposite in the summe...

Buying 2.0 Ton GeoCool Geothermal Heat Pump Kit

Geothermal systems extract heat from the earth’s surface. This clean, renewable energy source depends more on the consistency of underground temperature instead of the fickle weather above the ground. If you’ve visited a cave or mine, you may be aware of this phenomenon.   Used for both cooling and heating purposes, the geothermal systems can be found almost anywhere. As more countries and cities around the world work to reduce their dependence on fossil fuels, more areas consider this clean source of power. Conventional geothermal kits work by using pumps to heat or cool fluid and bring above ground to control temperature inside home. Though it may sound like a relatively new type of technology, the heat energy has been used successfully. Currently, the U.S. Department of Energy estimates that the geothermal heating systems are installed in 50,000 American homes every year.

How Do You Buy the Best Inverter for Solar PV Systems

Do you want to ensure your solar panel operating efficiently and no interruptions? Probably, you should consider either microinverters or power optimizers. SolarEdge is the premier power optimizer in the United States, whereas Enphase leads for microinverters.   Making a decision of which inverter to choose for solar PV systems can be difficult. The product warranties make a great difference. Are you standing on a fence of choosing between SolarEdge and Enphase? Let us help you out: SolarEdge vs. Enphase – Both Enphase and SolarEdge come with a strong 25-year warranty. Enphase doesn’t cover labor costs if you want to replace the products under the warranty. The warranty for their monitoring system is much lower than SolarEdge. SolarEdge can offer you the option for an extended warranty for their inverters. When you buy SolarEdge power optimizer, the extended warranty may be worthwhile. It’s due to the reason that string inverters don’t last long li...
