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.

The cost to charge an electric car in the UK varies between home, work and public charging.

For a typical electric car with a 60kWh battery and ~200 mile range:

• Charging at home: Costs about £9.20 for a full charge. *
• Charging at work: Many employers will install workplace charging points and typically offer free access throughout the day.
• Charging at public locations: Public chargepoints at supermarkets or car parks are often free to use for the duration of your stay.
• Rapid charging: Rapid charging points are normally found at motorway service stations and typically cost £6.50 for a 30 min, ~100 mile charge.

Charging an electric car at home costs about £9.20 for a full charge* and is the most convenient and cost-effective way to keep your car fully charged. Most drivers will charge their electric car overnight, waking up to a full battery every morning.

Average domestic electricity rate in the whole of the UK is about 17p per kWh.

Fully charging a 60kWh electric car will cost between £9.00 and £9.90 (depending on where you live) and give you about 200 miles of range.

* Costs calculated at 17p/kWh based on usable battery is ~54kWh (90%).

Obviously the performance of a solar thermal system will vary depending on the location of the home, the insulation of the property, and your own hot water requirements. Solar thermal panels are capable of providing all of your hot water requirements from April to September. They will still make a contribution to your hot water needs for the rest of the year, but in general you will need a backup system to further heat the water in the colder months.

What Are The Best Electric Radiators?

Being afforded options in life is what we all seek. However, when the options are obviously too much, it can have a negative impact - exactly the case with electric radiators. With so many electric radiators in the market today, identifying the best and most suitable one for your home can be less helpful and extremely confusing, and even more so when you don’t know what you want. In a world filled with a huge selection of electric radiators, some designed for general heating while others are designed for more specific purposes, where would you get started? Here we’ve put together some of best electric radiators which you can put into consideration when making a decision. Let’s have a look!

• The Rointe D Series

The D series is one of the most popular electric radiators you’ll in the market today and deservedly so.with an advanced controllability via the Rointe Connect App and TFT control panel, these series have been rightly marked out as the most sophisticated electric radiator till date. What’s more? It’s suitable for both small, medium and large rooms, as it heats from 3m2 to about 16m2. The installation and programming of the Rointe D Series is very easy as it also enables a full access to every functions included as well as consumption costs.

• The Dimplex Q-Rad

As a high end heater, the Dimplex Q-Rad is one of the most popular brands. It is designed for a large room as it can heat up an area of about 20m2. The electric radiator features simple controls, sleek and good looks and works automatically all day.

• The Haverland RCTTi

This is conveniently one of the most efficient and reliable electric radiators you’ll find around. It stands out with the possession of its Dry Stone technology which works to ensure the room is kept at the right temperature.

• The Stiebel Eltron CND

Featuring a combined radiant and convection heating, this dual heat source is a very good option for homeowners with a tight budget. It works excellently to store heat which it later releases. The electric radiator also sense when the windows are open and react intelligently to the environment.

When it comes to the electric vehicles world, one of the most common questions that’s usually asked is - how to charge my electric car? If you’ve carried out some research, you’d would have seen terms like level 1, level 2 or level 3 being thrown around. In this post, we’re going to consider the meaning of an ev fast charger to give you more insight into the electric vehicles world. Let’s take a look!

As the name suggests, fast charger is an electric vehicle charger that’s a lot faster than the average ev charger. These incredibly powerful units can have your vehicle charged to 80 percent within an hour depending on the model and capacity of your car while also being highly convenient for those who are always on the go. So what’s the difference between rapid and fast car chargers?

Generally, fast car chargers are available in two varieties which includes - the 7kW which is the most popular option used in homes, or 22kW which is commonly used in supermarkets as well as shopping centres. While 7kW takes up within 4 - 6 hours to charge an ev battery to 100 percent, 22kW will take about 1 - 2 hours to do the same. Most fast devices will be AC, there are also some DC ones available as well. What’s more? A large majority of fast car chargers are untethered. This implies that the cable isn’t connected to the device allowing you to make use of your own. This can, at times, make it a lot more convenient than rapid chargers which makes use of tethered cables.

Electric heating has several benefits. It can be paired with renewable electricity generation, so the electricity used to heat your home will be sustainable. Underfloor heating is very efficient and can be cheaper than comparable gas or oil fired systems.

Like every other systems in your home, solar hot water systems will require periodic inspections as well as a regular maintenance in order to keep it running as efficiently as it should. Not only that, the various components will also require either repair or replacement from time to time. It’ll also be proactive to take the necessary precautions so as to prevent worrying issues like corrosion, scaling or freezing.

Is it a task you can handle on your own? Well, there are some inspections and maintenance activities you should be able to handle on your own, however, you’ll also require a qualified technician to carry out the more technical or complicated tasks. You should also take note that it may actually be more cost effective to have some systems replaced, shut off or removed completely than having it repaired. Here are some of the essential inspections that should be carried out on solar system components. They include:

✓ Collector soiling. Periodic cleaning of your collectors is important especially in dry and dusty climates.

✓ Plumbing, ductwork and wire connections. Check the pipe connections for fluid leaks. Examine duct connections and seals. Also make sure that all wire connections are tight.

✓ Roof penetrations. Flashing and sealant around the roof penetration should be checked to see that it’s in a good shape.

✓ Collector shading. Check for shading of the collectors on annual basis as this may greatly affect their performance.

✓ Support structures. Examine all bolts and nuts which connects the support structures to the collectors for tightness.

✓ Heat transfer fluids. Anti freeze solutions in liquid solar heating collectors will have to be replaced periodically. And this right here is a task that’s best handled by a licensed technician.

Can You Replace A Gas Boiler With An Electric Boiler?

In the UK, there are about 22 million households that are heated with the use of a gas boiler. However, do not assume that they’re the best type of boiler to install. The fact is, if your house isn’t connected to the main gas supply, the best option is for you to install an electric boiler rather than a gas boiler. So is it possible to replace a gas boiler with an electric boiler? The simple answer is yes. Both heating system options work in varying ways and also with a different impact on the environment.

The gas boiler is able to generate heat with the help of a gas burner. A heat exchanger is linked to the burner and heats the water available in its chamber. The hot water is then supplied to the heating circuit.

However, the thing is that natural gas can actually be more affordable when compared to using electricity to operate your boiler, but they have a negative impact on the environment. This is because gas boilers make use of an odourless, colourless and poisonous gas - carbon monoxide.

Meanwhile electric boilers are powered by electrical energy, hence, no carbon monoxide leak risks. Instead of using gas to heat up water, electric boilers distribute energy to heating elements which, in turn, heats up the water. So thinking about what’s best for the environment, you’d go for electric boilers. However, they’re more costly and are not as efficient as oil boilers.

If you reside in a smaller house that’s not connected to the main gas supply, then you might want to consider installing an electric boiler. However, if you live in a larger house, an electric boiler may not be the best option as they’re mostly designed to generate little quantity of hot water.
