Are you currently considering installing a ground source heat pump in your home? Well, a heat pump can be a great alternative when compared to gas or oil boiler, however, you may also be worried about the operating efficiency of this heating system if you live in a cold climate or during the winter months. However, in reality, there’s nothing to be worried about!

A ground source heat pump works by incorporating the natural heat that’s typically found in the ground or groundwater. In other words, this type of heat pump doesn’t make use of fossil fuels to heat your home while it can also minimize carbon emissions that may pose a huge risk to the environment. This makes a popular option especially amongst home and property owners who are very environment conscious and prefers to utilize more renewable sources of energy.

However in a place such as the UK where the temperature can drop to around -10℃ during the winter months, it may get you thinking whether there’ll be enough heat in the ground to warm up your home. Let’s have a look.

In the UK, the temperature of the ground doesn’t normally fall less than 10℃. This is still enough heat for the ground source heat pump to warm up your home. In other words, as long as you purchase the right one, your ground source heat pump will continue to work just fine during the cold months. Due to the fact that every heat pump varies, you will need the right equipments so as to ensure the heat pump works well throughout the winter. This is usually not an issue in the UK, but same can not be said of colder places like Canada and North America.

If you’re looking to install some new solar panels in your home or property, then you’d probably want to know how it works. This is one of the most frequent questions asked by homeowners when it comes to solar panels and in this article we aim to give you a good insight on the operations of solar panels. Let’s have a look!

Generally, solar panels work by absorbing the energy of the sun and then converting it into electricity. It functions by allowing photons from the rays of the sun release the electrons free from atoms within the photovoltaic or solar cells in order to produce a flow of electricity. There are several solar cells that are connected together ( usually 60 or 72 ) in each panel. Individual cells comprises both a negative layer and a positive one which combines perfectly to create an electrical field in which the energy is generated.

The boron that’s within the bottom layer generates the positive charge, while the phosphorous found in the silicon layer produces the negative charge. In order to convert the sun’s rays into the energy that’s going to be transported from the panels to the inverter, the two field will interact with one another.

In other words, solar panels work by turning photons from the sunlight into direct current which is transmitted to the inverter. Once it gets to the inverter, it’s then translated to alternating current and send this current to to your electric box which powers the entire home. If you do not wish to reduce the high bills that’s associated with renting power from the grid, the solar energy system is an efficient and affordable way to achieve this aim.

There are a few factors that will determine whether it’s worth getting a solar battery. They involve how much electricity you use, how often you’re at home and whether you receive any export payments.

To work out whether it’s worth getting a solar battery, you need to work out how much of the electricity you generate you’re using already. If you’re able to run all your appliances during the day while your solar panels generate electricity, then it sounds like you’re already using your electricity well. It might not be worth you getting a solar battery in this case.

However, if you’re not at home for a lot of the day, then you’ll be missing out on the electricity your panels are generating while the sun’s shining. If you install a solar battery system, you can store the electricity that your panels generate in the battery and use it when you get home. This will help you cut your electricity bills even further.

You’ll also need to consider whether you’re getting paid to export your electricity. If you’re on the Feed-in Tariff scheme (FITs) or receive payments from the Smart Export Guarantee (SEG), you’ll get paid for every unit of electricity you export to the National Grid. Before you decide whether it’s worth getting a solar battery, you’ll need to weigh up whether you’d be better off carrying on exporting your unused electricity rather than storing it to use yourself. If you’re unsure, visit the Energy Saving Trust’s website or speak to an MCS-registered installer who will be able to help you work out which is more cost-effective.

First and foremost let’s look at the meaning of a ground source heat pump. A ground source heat pump is simply a renewable heating system which happens to absorb the low temperature solar energy stored in the ground or in water with the help of a pipework that’s submerged and converts this energy into a higher temperature through compression. A ground source heating pump is capable of supplying the entire heating and hot water needs of a building throughout a whole year regardless of the season. So how exactly does a ground source heat pump work? Let’s have a look!

In principle, a ground source heating pump makes use of a refrigeration system but in a reverse form as it extracts low temperature heat from one point or location which is the source and transfer a higher temperature heat to another point or location - the sink. The pumps are powered by electricity and the operational principle can also be incorporated at generating both heating and cooling energy.

Knowing fully well heat naturally flows from warmer to cooler places, the ground source heat pump takes advantage of this physics by distributing a cold fluid via ground array pipework either in the ground or in water. It’s able to extract low grade energy from external sources of heat which includes soil, rock, lakes as well as streams.

Once the absorbed energy has been released to the heat pump from the ground or water, the fluid proceeds with its circuit back to the pipework to start its cycle all over again. Some of the benefits of the ground source heat pumps includes low carbon emission and improved air quality, efficient and affordable heating, the use of free heat from the ground and lots more.

When you’re about to transform from the standard electricity to solar energy, what determines your solar system’s size is the amount of solar that’s required. The amount of solar that you’ll need, on the other hand, requires considering the end goal, be it to increase money savings, reduce environmental contamination, maximize Returns On Investment ( ROI), or just to copy what the neighbour’s done.

In order the determine the number of solar panels that is needed, the first step would be to calculate the number of kWhs that’s currently being used. A kWh is what’s used to determine the amount of energy that has been incorporated over time which the utility uses to bill you. What’s strongly recommended to create a suitable range is a 6 to 12 months average of your household electricity bill. Other factors that can play a key role in the determination of the number of solar panel needed include the following:

✓ Sunlight exposure hours. In order to know just how much energy your solar panels will generate, there’s a need to know the number of direct sunlight hours you should expect on a daily basis. For example if you stay in a region that’s usually very sunny, then it’ll be reasonable to expect more energy production per panel than regions that are usually cloudy.

✓ Angle and size of the roof. Roofs with a lot of workable space may require to let go of some efficiency opting for larger and cost effective panels to achieve the targeted energy. However not all homeowners have sufficient roof space or shade coverage for the solar panel they actually want. Also, the degree at which the roof slants will also determine if the sunlight is hitting the panels well enough and the amount of energy that can be generated thereof.

Most domestic solar thermal panels do not need planning permission and are covered by permitted development rights. There are restrictions on the size and location of these systems. If you live in a conservation area or listed building, or want to install a very large solar thermal system, check with your local authority to see if you will need planning permission.

Unlike the photovoltaic (PV) power which works to turn a part of the electromagnetic radiation of the sun directly to electrons and electricity, a solar thermal can simply be referred to as the absorption of the sun’s heat for human use. As a result, the solar thermal has a wider range of uses than the PV does in several ways. This is due to the fact that the sun’s heat can be absorbed and transported via a medium and the stored energy incorporated for several great purposes such as to heat water, to heat and cool a home or living space, to prepare a meal as well as to generate electricity. All these functions are useful for both residential and commercial spaces.

There are generally three different ranges of solar thermal energy that are being used which includes the low temperature ( for heating, cooling as well as ventilation), the mid temperature ( used for preparing meals, heating hot water and the likes) as well as the high temperature ( used for generating electricity). To focus more on generating electricity, there are a wide array of ways through which the sun’s heat can be directed at creating electricity via a heat exchanger which operates to super heat water or inert gas to power an electricity- generating plant or to produce electricity via a Stirling engine.

In order to increase their output or make them more efficient, evacuated glass tubes are used to encircle the tubes which in turn helps them to collect more heat energy while also protecting them from re-radiating the heat energy absorbed. The trough are normal positioned north to south as well as to keep tabs on the travels of the sun throughout the day.
