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.

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.

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.

How Do Electric Boilers Work?

Electric boiler are installed in residential, commercial and industrial properties to serve as a reliable source of heat. Unlike other types of boilers that depends on fossil fuel burning to be able to operate, electric boilers are fuelled by electrical energy which ultimately makes it more reliable and powerful compared to its counterparts. This heating option was basically provided for home or property owners who don’t have an access to the main gas supply.

So how does an electric boiler work? Basically, an electric boiler work by heating water. Once heated, the hot water supply is then distributed to various areas across the house or property. In order to achieve the best possible efficiency at the lowest possible costs, new model electric boilers are installed by licensed and professional boiler fitters with the help of a microchip control system. Meanwhile, the microchip control system functions to oversee the management of both temperature level as well as output.

Unlike other types of boilers such as a gas boiler, electric boilers only require minimal service. If you own a gas boiler, it’s crucial to ensure that it’s serviced every single year by a licensed and reliable professional that’s into boiler repair services. During the checks and maintenance services, the gas boilers would need to be checked for possible gas leaks, as well as ventilation poisoning and other problems.

Overall, electric boilers are considered to be one of the most environment-friendly heating system which is more affordable to install in your property than a gas boiler. It represents the most ideal option for homes with gas boiler issues as well as those that are not connected to the main gas supply. What’s more? Electric boilers are also one of the best options for wet central heating and under floor heating.

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.

If you are thinking of buying an electric vehicle, then one of the first things you’d have to put into consideration is charging. When it comes to charging of your electric vehicle, doing it at home is one of the most convenient things that comes with it. Not only do you get to avoid the fuel stations, but you’d also get to drive a car in a much cheaper way. Fitting an EV charger or wallbox at your residential space gives you the option to add miles to your battery in a lot faster manner than making use of a three pin plug. In fact, there are also some chargers that offers a lot more than just being a fast way to charge your vehicle.

So which home ev charger should you use? There are a wide range of options available in the market today, however you can get the perfect match for your vehicle by answering these few questions:

• Can you park two cars side by side? If yes, then a tethered charger might just be your most suitable option. A tethered cable is one that’s always connected to your home’s charger. One of the major benefits of using this is that you can get home and plug the charger straight it without having to fetch the cable or carry it around.
• Is size and design crucial? If yes, then you can consider wallbox chargers or untethered wallboxes which are smaller in size and minimalist in design.
• What if your WiFi isn’t accessible? If your WiFi signal is poor in the spot where the charger is to installed but your mobile phone signal is good, then Ohme is a good option to consider.

Are Electric Radiators Expensive To Run?

Just like many home additions, the running costs of electric radiators varies largely on a number of factors. Great number of electric radiators typically comes with an in built thermostat which is designed to turn itself off automatically when not in use in order to save energy.

However the energy provider’s set electricity charge tariff will also have a great influence on an electric radiator’s running cost. Let’s take a look at the running costs of an electric radiator!

A 600 Watt electric radiator ( on a standard electricity tariff) will usually have a running cost ranging between 4 to 6 pence each hour. However you should also take note that this scenario might change in situations whereby the electric radiator is not calling for heat the full 60 minutes of each hour. And this is more likely to be the situation as the thermostat is programmed in such a way that enables it to turn itself off immediately there’s an achievement of your required room temperature level - usually within 10 minutes from the time it was switched on. As a result of this, the running cost per hour of electric radiators will be greatly reduced to just about 1 to 2 pence.

It’s also important to note that enhancing the insulation of your home can go a long way to add to the heat retention value of each room. Consequently, the duration at which the electric radiator calls more heating will be significantly reduced, which in turn, implies a lower electricity bill.

Another key factor that can play a huge role in saving on your heating bills is the programming as well as usage of your electric radiators. Every radiator comes with an independent digital thermostat with a number of 24/7 programming options to help achieve maximum efficiency. When the radiator is properly set according to your lifestyle, you can save as much as 50 percent on your heating bills.

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.
