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.

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.

• The power of your solar panel system – there's no point buying a higher capacity battery if your system will never generate enough electricity to charge it
• How often you think you will need to charge your battery
• Your budget
• Whether you care about having the latest technology and a recognisable brand name

For most homeowners, rewiring a house is always a sore subject they’d prefer to avoid especially when they think of the expenses they’d have to incur or the mess and complexity that the project involves. However, this is a subject we’d all have to face sooner or later as an old wiring poses a lot of drawbacks, while an improper wiring can also prove to be more expensive and even cause more damage as it can lead to not only electrical shorts but also electrical fires. When a wire triggers a spark or a current overload, this can cause fire and the entire house may be down in ashes within a couple of minutes. Hence, one of the several reasons why house rewiring is just too important to ignore.

In this FAQ, we’re going to take you through the house rewiring process so as to ensure that your project is done to perfection. However, if you do not feel confident enough to pull this off, we’d strongly recommend you get in touch with a reliable electrical professional who can guarantee that a safe and effective work is done.

• Firstly, you’d have to upgrade the main service panel to a minimum of 100 amps
• Fit dedicated circuits in the service panel for all the home’s major appliances.
• Allow for a space of about 6 to 8 feet between electrical outlets throughout the house in order to cut out the need to run extension cords which could be a fire hazard.
• Install only three-prong type to avoid electrical shocks when fitting new outlets.
• Using ground fault circuit interrupters, fit outlets in the bathrooms, kitchen as well as outdoors. These outlets will shut themselves out so as to prevent electrical shock when wet.

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.

The importance of selecting the right size battery for your home simply cannot be overemphasized. A lot of home and property owners are facing this challenge and understandably so. Selecting the right battery size for your needs depend on a number of factors which includes your motive for adding a battery, your electricity usage, your budget as well as your panel array size, be it new or existing. In this post, we’re going to take you through some of these factors to help you determine the right battery size for your home or property. Let’s take a look!

• Your motive for getting a battery. While most people purchase a battery to wipe out their need to purchase electricity from the grid with the hope of making some savings, others add a battery so as to enjoy backup power. There are also some who just needs it to power their home with solar energy. It’ll not be economical to size a battery to effectively take you off the grid, but if your motive is to make savings, then you’ll should expect to purchase some electricity from the grid during the year.
• Electricity usage. The average household uses about 16kWh of electricity on a daily basis. During the daylight hours, most of these household will use a third of their electricity when the solar panels are still generating electricity, while the remaining two third are purchased from the grid. In other words, you’ll require a minimum of 10kWh battery capacity if you were to use a battery to power the electricity you purchase from the grid.

For a typical British household, you’ll most likely need a 5kWh solar power system which normally generates about 17 to 21 kWh on a daily basis depending on your location in the UK.

There are a range of variables that will determine which heating system is best for your home, such as the level of insulation and size of rooms. However, electric heating is suitable for many homes. Electric boilers are very compact and do not need a flue. Underfloor heating is effective at heating rooms of any size.
