Unlike in houses built in the 1970s where a good majority of the houses will not need to be rewired, for houses built in the 1960s you’d probably need to rewire the entire house unless the wiring is the modern PVCu coated type. Generally, the homes built especially in the 1960s and 1970s brought about enormous changes. This is because over the years our way of living began to change and as a result, our need for electricity became even greater. In response to this, the electrical systems we incorporate needed to change in order to match the new set standards.

In the 1960s, the amperage normally used was increased to 100, which enables home and property owners to power their dishwasher, microwave as well as refrigerator all on one circuit. However, while this may be a remarkable improvement for our grand parents, this is just enough to cater for our modern day appliances. In recent times, new homes are constructed using a wide range of dedicated circuits due to the fact that each of our appliances makes use of much more electricity to function. Consequently because the 100 amp panels of the 1960s possessed restricted space for breakers, home and property owners who still had the units in their homes will inevitably require a sub panel or a new panel entirely - meaning a total rewiring of their property.

Furthermore in the 1960s, builders turned to aluminium from the previously used copper as it was a great conductor and also happens to be relatively cheap. However, after a couple of years a host of electrical fires cropped up in houses that are wired using aluminium. It was later discovered that when the switch to aluminium was made, the light switches or receptacles which were originally made for the previously used copper was overlooked. It was learned that there’s a corrosive chemical reaction that arises as a result of the two dissimilar metals when connected. Hence, the more reason why aluminium wired houses in the 1960s needs to be rewired.

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.

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.

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.

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.

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.

There’s a need to ensure that all the paperwork are in place,before putting your house up for sale on the property market. An very good example of such essential document is the Electrical Installation Certificate (EIC) which is used as a proof to attest to the fact that the electrical installation works carried out on the property in question was actually done and also whether or not it satisfies the building regulations. It’ll be a contravention of the law to put your house up for sale or actually sell it without producing this important document. Therefore, if you’re looking to sell your house you may wish to know the electrical documentations you need to complete the task. In this post, we aim to provide you an in depth insight into the electrical certificates needed to sell your house while also helping you make informed decisions along the process. Let’s take a look!

You’ll need to obtain two certificates in the event whereby the electrical work done was performed by a registered and qualified electrician. The two documents include:

• The Building Regulations Compliance Certificate - This is provided to confirm that the electrical works done complies with the Building regulations.
• The Electrical Installation Certificate (EIC), alternatively you can have a Minor Electrical Installation Works Certificate which is provided to confirm that the electrical works done satisfies the BS 7671.

In addition, the local building control body must be provided with a copy of these documents. In such an event whereby the electrical work was completed after 2013 and either it was done by yourself or by an individual who isn’t a registered professional, then there’s a need to make sure that work is inspected by a registered third party certifier within 5 days of completion. If the work is found to be satisfactory, you’ll be issued a copy of an Electrical Installation Condition Report.
