Tesla’s top-of-the-range battery storage system is still one of the most expensive on the market. It has a huge 13.5kWh usable capacity and can even keep you up and running during a power cut. But how long does a Tesla Powerwall battery last? And does this mean it’s worth investing in one?

The Tesla Powerwall 2.0 comes with a 10-year warranty. But Tesla says that it should last way beyond this – at least 5 years longer. The standard warranty says that it should work at 70% capacity for the full 10 years – so if it loses more than 30% of its storage capacity within that time, it should still be covered.

While the Tesla Powerwall does last a long time, it has a large capacity that most average households won’t require, and it’s a costly option. After installation, the Powerwall 2.0 will set you back between £6,500 and £9,000, so ideally you want it to last past its 10-year warranty.

Before you splash out, consider the size of the solar panel system you want to install or you already have. Will it generate enough electricity to make it worth storing in the Powerwall? If not, are you expecting to upgrade your solar panels to a larger system in the future? If you are, then it might be worth investing in a Powerwall. It might also be better to wait until you come to upgrade your solar panels – the solar battery price trend is going the same way as solar panels, so they will probably continue to decrease in price as more people adopt the technology.

If you’re considering getting a solar thermal system, one of the first things that comes to mind is the possibility of the system functioning properly during the cold months. The short and simple answer to this question is yes, a solar thermal system works in the winter. However, the downside here is that it’ll be a lot less efficient when compared to how it operates during the warmer months or summer. As a result of this fact, you’ll likely need to rely more on your boiler, immersion heater or any other backup heating system during this period as your solar thermal system will fail to contribute as much as it does during the warmer months. So what exactly is the reason why solar thermal is less effective and less efficient in the winter period? Let’s have a look!

As you know, solar thermal system banks on the sun’s energy to heat the water for your home’s use. During the cold months or winter, the sunlight becomes a lot less available when compared to the warmer months, as a result, there’s less sunlight that’s available to be used for its solar energy. And even more so at the periods when the days are shorter or skies are clearly overcast.

Also having a great impact on a solar thermal system’s output is heavy snow. Flat plate collectors normally have the capacity to cope better during snowy conditions as the light that’s able to travel through the snow will heat up the absorber plate - thereby making the snow slide off more quickly. However, the case is contrary with evacuated tube collectors which possesses a form of vacuum insulation that’s crafted to minimize the loss of heat, meaning they can’t generate heat to melt and cause the snow to slide off in a similar way.

Solar thermal panels work by capturing heat directly from the sun and using it to heat water. This hot water is then passed through a coil to heat the water for your central heating system. Solar thermal systems are compatible with many existing conventional boilers with hot water tanks, and can be set up to feed in to your existing heating system.

If you’re thinking about getting a solar thermal system for your home, it’s normal to consider the possibility of using the system for central heating. So is this viable? In this article, you’ll learn how solar thermal panels can be incorporated for heating. Let’s have a closer look!

Heating and hot water systems, on the average, takes up a sizeable part ( up to 70 percent) of our energy bills. Now take a moment to imagine how cool it’ll be to generate your own hot water for free without having to depend on any supplier which in turn significantly reduces your energy bills. Well, this is exactly the work of central heating systems that are powered by solar. That’s super cool, right? Well, let’s have a look at how this works.

While solar panels generates electricity, solar thermal panels produces heat for hot water production. However, what’s important is the fact that they both make use of the sun’s natural energy to provide us with a free and renewable energy we can use in our homes. Here’s how it works.

Solar thermal panels directed at central heating incorporates the sun’s natural energy to heat water in a storage cylinder which is then available for use at home. These solar thermal panels are exposed to the sunlight by fitting them on the roof of the home. Generally, they’ll include tubes that contains liquid whose job is to collect the heat and then transfer it to a hot water cylinder that’s solar compatible in your home. The heat is generated for free and is also renewable. This is help you save lots of money on oil, gas and even electricity which you purchase to power the cylinder.

When it comes to electrical works, safety is always paramount. Although a complete house rewiring service may seem quite expensive, when compared to the safety it provides, you’d realize it’s well worth it. We know all too well that human nature tends to prevail to overlook small electrical issues until it’s too late or probably gets out of hands. When this happens, not only will you have to spend more to get the issue resolved, but it may also lead to some damages to your property. Hence, the need to identify and resolve electrical deficiencies as soon as possible. In this post, we’ve compiled a shortlist of some of the top signs that your house needs rewiring. Let’s take a look!

• Dimming or flickering lights. This is one of the most common signs that your house needs to be rewired. When a light brightens, it means there’s too much voltage and when it dims, it implies it’s receiving too little voltage. You may be tempted to think this is a lighbulb issue, but this type of decline in power is usually as a result of a loose wiring or faulty circuits which should not be ignored.
• Regularly blown fuses. With the steady development in technology as well as electrical appliances within our houses, older style fuses that are not designed to contain this amount of electricity will end up blowing. If your fuse blows on a more regular basis, then there may be a need to upgrade them to more modern circuit breakers.
• Lightbulbs burning out in their sockets. This is usually a sign of bigger issues in your wiring which is often caused by fluctuations in voltage.
• Sparking outlets. These can be perfectly normal, but at times they can also be a clear signal of a potentially dangerous problem which should not be ignored.

If you’re planning to get an electric vehicle, the next thing that naturally comes to mind is getting a good charger with it. As a result, this is one of the most common questions asked when it comes to electric vehicles. We’ve put together this list of some great home ev chargers to help you make the best informed decision possible moving forward. Let’s take a look!

• Charge Point Wi-Fi Enabled Level 2 EV Charger. If what you need is a faster charge for your car due to the high frequency of usage of the electric vehicle, then this charger might just be the best option for you. It’s claimed to charge electric vehicle batteries six times faster than a standard 120 volt home system. What’s more? The mobile application will inform you about the amount of charge your battery has regardless of your location. This feature can be of great benefit especially when you’re trying to determine whether to put in an additional hour at work or heat straight home.
• Juice Box Pro 40 Level 2 EV Charger. This is a level 2 charger which features a web based charging control so as to allow you control the charging parts of your vehicle from anywhere, be it in the comfort of your home or office without having to go to the garage or parking lot.
• Siemens VersiCharge VC30GRYU. This is an easy-to-use plug and play installation that comes with a mounting bracket if you happen to own a NEMA 50 receptacle. It boasts a charging time that’s 4 times faster than level 1 electric vehicle chargers and possess a charge delay feature or 2, 4, 6 or 8 hours.

How Does Electric Central Heating Work?

An electric central heating works to provide a number of benefits for you. These benefits include the following:

lSpace Heating

• The storage heaters work during the night to store electricity which would be used to heat up the heat retaining bricks. This, in turn, will release this energy throughout the day to warm up the room.

• There are also electric radiators which works to deliver on-demand heat and as a result, economy tariffs are totally avoided. It will generate heat by itself rather than storing it and with the controls, you can easily determine the amount of heat to be released when you require it.

• There is the wet electric system options as well which comes with water filled radiators. This operates in a similar way to normal radiators, however, it makes use of electricity to heat up the water.

lWater Heating

• An electric boiler operates in a very similar manner to other boiler types, just that it makes use of electricity as its fuel. Here, the water is warmed by a heating element and the water is later moved to several radiator throughout the house by a pump. These electric boiler types earns you tariff savings as you’ll be able to heat water at night.

• Heat pumps geothermal or air source, redistributes heat instead of creating it. Heat pumps are powered by electricity and it works by absorbing heat either from the air or ground which it then channels it through a pump. This can then be incorporated in heating either water or a room.

• A dedicated immersion heater is another water heating option. Here, the heating element is positioned inside a hot water cylinder. In a similar fashion to a kettle, the element heats the nearby water. Immersion heater can act either as a backup or your main heating element.

How Much Does Pat Testing Cost?

When it comes to Portable Appliance Testing (PAT) there’s no particular rule that determines how much such services can cost. However as a rule of thumb, you should take note that when calling in a professional PAT testing company they’re likely to charge within the range of £1 to £3 per appliance that’s going to be tested. However, if you have quite a number of appliances to be tested, then there’s a good chance that the price per appliance can be reduced to serve as a bulk discount. So the more the appliances to be tested, the better.

There are companies that actually offer a pricing that’s below £1 per item, however companies likely are most definitely going to have a fixed minimum number of appliances that are required to be tested or a fixed minimum fee like 60 portable appliances. It must, however, be noted that pricing can also go beyond PAT Testing as several professional companies will add some additional advantages which is more than just the test of each individual appliance. This kind of pricing can include other services such as a thorough visual inspection, plug rewiring as well as fuse replacements. They can also include stuffs like Pail and Fail labels in the pricing.

Generally, the average price of PAT testing will be based on various influencing factors such as the type of the appliance, setting, number of appliance to be tested as well as other related expenses. What’s more? Most PAT companies will offer a company with a PAT Testing Certificate so as to certify that the company is in total compliance and also remains a safe environment to work.
