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.

If you’re thinking about installing a solar thermal system in your house, it’s always important to put into consideration numerous factors before you proceed. While some solar thermal systems are suitable for use at home, there are also some that are suitable for businesses or organizations which normally requires a big amount of hot water like hotels, restaurants, schools, hospitals and many more. You’ll also find some types available in the market that are suitable for communities to satisfy communal hot water demands.

It should, however, be noted that solar thermal systems do not have the capacity to produce all the hot water demand of a house. In the UK, an average household will need an annual water heating of between 3000kWh to 5000kWh. Whereas, a solar thermal system is only able to meet about 40 percent to 60 percent of this demand.

With that in mind, it’s also worth noting that during the summer months when the solar radiation is at its peak and hot water demand is relatively lower when compared to other seasons, a solar thermal system may be able to provide all of your household’s hot water needs. This implies that during this period you may not find the need to operate your boiler at all. However, during winter or colder months, when you have a higher hot water demands in contrary to a lower solar radiation, a solar thermal system will only be able to take care of about 20 percent of your household’s hot water needs. And that ultimately implies that during this period, you’ll need to rely more on a alternative or backup source of heat like gas, coal, electricity, oil or LPG.

Home electrics can be extremely dangerous and it’s very unwise to try and carry out repair work or maintenance yourself without the necessary knowledge and skill. Therefore we would always recommend using a Part P registered electrician at all times.

Also commonly referred to as a consumer unit in recent times, a fuse box is responsible for controlling and allocating of the electricity in your home. They hold the power any time there’s an overload in one of the circuits which in turn, prevents fire as well as electrical damage. Fuse boxes are often incorporated in homes but consumer units are very rapidly replacing them. Therefore, when your fuse box breaks down, it’s always a smart decision to replace them with consumer units due to the fact that they’re safer and also comply with building regulations while also being a lot easier to use. If you’re extending your home, upgrading to a larger capacity model enables you to make use of more power with the power overloading. In this post, we’re going to cover the amount you’re expected to pay to replace or install a new fuse box or consumer unit as well as the factors that may affect the cost.

For a 10 way dual RCD consumer unit, the typical cost range will be between £250 to £600, meanwhile 15 way dual RCD consumer unit should cost within the range of £300 to £700. Overall, the smaller the house, the fewer the circuits that’ll be needed, hence the difference in the aforementioned prices.

There a number of factors that can affect the cost of replacing a fuse box. These factors includes the the size of the house in question ( the bigger the house , the more the circuits there are and the bigger the fuse box needed), the location ( for instance, places like London where there are higher demands are likely to be more expensive than other regions ).

Periodic testing and inspections should be completed: Every 10 years for your home, Every five years for rented accommodation, Every three years for a caravan, Every year for a swimming pool.Electrical inspections are also carried out when buying, selling or renting a property.

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.

It might be possible to fit electrics in your shed, depending on where it is and what it’s made of. You should get in touch with a qualified electrician to find out whether it’s possible. Never attempt to run electrical cable from your house to an outbuilding!

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.
