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.

Geothermal Systems

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.

As you plan to invest in solar PV systems, you are likely to come across different terms that you are not familiar with and feel confused about them. Frankly, you are never alone in this race. The same happens to others who are all set to use solar power in their homes or offices.  

Dreaming of using the solar energy and minimizing the fat utility bill requires you to decide on a few crucial things. One of them is whether to keep without or with power from the grid? Since there are lots of advantages to installing solar on grid systems, you will have to make a choice from the battery less grid-tie systems or battery based grid-tie systems.

What are the Solar on Grid Systems?

On Grid Solar PV Systems are also referred to as ‘grid-direct systems’, ‘solar grid tie systems’ or ‘grid connect systems’. These are ready to install kits that will be connected to the grid or energy power supply in order to continue with the supply even when the solar system fails to produce adequate energy for your home. It means that grid power will be available for use at the time when your solar panels don’t generate the exact amount of electricity you need, i.e. at night or in cloudy and frosty conditions. As a result, the pressure on a solar grid tie system will be minimal. If ever it ends up generating more power than required, it will divert it to the grid for future use.

In the absence of sunshine, solar PV panels cannot perform at peak levels; still, you can conveniently get electricity from the solar on grid systems to meet your needs. You can also join a net metering program which will enable you to receive rewards from your electricity supplier for sending excess energy to the grid in your area.

Just stay refreshed, energized even when the grid is down and protect yourself from power outages. Know your solar on-grid system.

Key Components of Solar on-grid Systems:

  • Solar PV panels of different size
  • An inverter to mobilize and control the conversion of Solar

Top Reasons Why You Should Consider Using Geothermal Systems

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 summer to collect heat from the house and send it back to the earth surface. Hence, the geothermal systems are far more energy efficient than conventional heating and cooling systems. They use much less energy than what they remove or supply. It results in a 4-5 times higher Coefficient of Performance (COP). Each ground source heat pump has an energy rating defining this factor. Modern day geothermal heat pumps are seen to be operating at 4 times more efficiency. So the biggest benefit of using them is that for every 1 Kw of energy you spent to run the compressor, you get 4 Kw of Free Energy from the geothermal systems. With a Coefficient of Performance of 4, you can enjoy as much as 66% cut down on heating and cooling cost. Similarly, a COP of 5 will bring you 75% savings on heating and cooling bills.

There are four basic options available in geothermal systems. Your choice depends on the local topography and water or ground available nearby. Both the horizontal ground loop and the well loop are the simplest ones to install at any time. Water loops can be opted only when there is a lake nearby to support the geothermal system. 

Let’s know about the best reasons to consider installing a geothermal system in your home or office:

Geothermal Systems

1.    Reduced operating costs: A geothermal system shows -5 times higher Coefficient of Performance (COP) cutting down the energy bills by 66-75 % when compared to conventional heating and cooling systems.

2.    No harmful effect on the environment: Geothermal system produces free green energy which is renewable and eco-friendly.

3.    Lower repair and maintenance costs: By ruling out the higher temperature discrepancy, geothermal parts are less likely to undergo more stress and pressure, lowering the necessity of repair and maintenance annually.

Solar Water Heating(SWH) System

Each time you feel the warmth of the sunrays on the rooftop or courtyard, it reminds you of a natural energy source is always there for the hot water and space heating needs at your home. It is available in an unlimited amount and at free of cost!


You may be aware that it is possible to convert sunlight into electricity using the solar panels, but it may feel shocking & interesting for you that the same can generate heat energy for solar water heating and space heating. Solar water heating is a cost efficient technology in use to produce heat energy in abundance for your domestic or commercial needs. It will save money on utility bills which will ultimately pay for the SWH installation cost.


Selecting the best solar water heating system may not be easy without proper knowledge; it is recommended to seek for a specialist’s help, who has experience of installing the SWHs and providing quick consultation on them. There are two widely used varieties of solar water heating systems available for your choice.  A Passive solar water heating system does not require any pump induced energy but, the natural gravitation force to help the water circulate from collectors to the tank. It has less number of mechanical parts, reduced maintenance/servicing cost and low expenses for initial setup. Whereas an Active solar water heater is a more expensive, yet energy efficient type having pumps and controls to aid in the process of water circulation.

Both of these solar water heating systems include two key components – a solar collector and a water storage tank. The solar collectors capture the sunrays before converting them into heat energy. They can be of the following types:

  • Flat plate collector:  well insulated and glazed collectors following a flat-plate assembly method
  • Evacuated-tube collector: the transparent and energy efficient glass tubes arranged in rows with little scope for heat loss from them.
  • Integral collector or Batch collector: a system made of single or multiple tanks or tubes kept in an insulated box for long term water storage. It does not fit cold climates due to the risk of freezing pipes in heavy cold condition.

While looking to pick up the best SWH for your home, you need to review the solar water heating systems from all angles. It is the geographical region, climate condition and your home’s position that will be crucial in deciding which solar heating system will be perfect for you.

The active solar heating systems can make up for your extra expenses with lowered utility bills per month. They can be of the following types:

  • An indirect circulation system uses a heat exchanger to transfer heat into the water storage tank from a nonfreezing fluid circulating in it. This kind of system suits the very cold regions where the temperature may fall drastically to cause the pipes freeze at any time.
  • A direct circulation system uses pumps to let the water circulate through the collectors and then flow back into the storage tank. They function well in mild climates where there is no risk of temperature going below the freezing point.

Passive solar heating systems are normally more reliable, durable, less costly to install, but they are not as efficient as the active ones.  They can again be of two types:

  • A thermo-syphon passive system makes the hot water rise from the collector to the crest of a tank without the use of a pump. In this case the collector is fitted underneath the storage tank to make use of the natural gravitational force.
  • An Integral collector-storage passive system assembles hot water in storage tanks or tubes that are placed inside an insulated box and fits the best in mild weather conditions.

An apparent problem in using solar energy is the lack of control on the weather. If you reside in a dark and cold area with only a few sunny days experienced in a year or there is no south facing roof in your residence then the solar water heating may not prove to be as effective as it should.

If all these details can’t eliminate your doubts or confusion, don’t feel worried at all! Solar water heating systems have been in use for a long time but are not extensively used everywhere, therefore asking for advice and guidance from 123 Zero Energy would be a worthy step to take before looking to invest in one.
