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’re thinking about the possibility of installing a ground source heat pump in your home, then it’s normal to consider how efficient they’re in heating up a house before going ahead to make a purchase decision. In this article, we are going to address this question to help you make an informed purchase decision.

We know you’d prefer a single, accurate answer to this question, but the fact is, there are several influencing factors that can play a key role in the efficiency of a ground source heat pump installation. These factors include whether or not the property is well insulated, the fitting of a well designed system and the quality of its installation, the heat source that’s being used as well as the heating distribution system and its size ( under floor heating or radiators ).

The Coefficient of Performance ( CoP) measurement is used to imply the efficiency of a heat pump. This is basically the ratio between the amount of heat energy generated by the ground source heat pump and the amount of electrical energy or fuel it consumes. Therefore, the Seasonal Coefficient of Performance ( SCoP) is usually taken as a realistic measurement to cover throughout the year as its based on CoP at varying conditions as well as a standardized climate.

You must, however, note that there is no established Coefficient of Performance for ground source heat pumps as they can be influenced by a lot of factors as well as testing conditions. When they’re properly fitted, ground source heat pumps can achieve a quite high Coefficient of Performance.

Generally, a ground source heat pump can generate about 3 to 4 kilowatts (kW) of heat for every 1 kilowatt to electricity or fuel it consumes. It’s able to achieve a higher efficiency when compared to its counterparts by using the freely available heat energy from the ground.

The more you’re at home during the day, the more you can save on your electricity bill, since solar panels generate electricity during the day. The Feed-in Tariff scheme (FITs) ended in March 2019, but the new Smart Export Guarantee (SEG) pays you, via your energy supplier, for the electricity you export back to the grid. With the savings involved in generating your own electricity and SEG payments, you can expect to save up to £390 per year on your electricity bill.

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.

When people think about heat pumps, they’ll automatically have the believe that a swimming pool will require a big heat pump. Since the swimming pool has a large volume of water, then warming such a volume will require a large ground source heat pump because that volume is much larger than the normal domestic hot water tank, right? Well, that point of reasoning does seem logical especially with the information almost everywhere that ground source heat pumps are usually less efficient when it comes to heating hot water for home’s use. However, the fact is there are also some things to put into consideration that also works in favour of the ground source heat pump.

First and foremost, you should know your domestic hot water will typically be heated to a much higher temperature when compared to your swimming pool. Since you wouldn’t be using the water to disinfect your bathroom or doing your dishes in your swimming pool, then the temperature can be much lower. In fact, it’s much more comfortable and enjoyable to heat to a typical “swimming pool temperature than having it at a hot bath temperature. If you’ve ever wandered into a really hot swimming pool, you wouldn’t need any introduction to the painful discomfort that comes next.

As a result of this low temperature, your “tiny heat pump can operate a in a more efficient way which makes the use of ground source heat pumps a viable swimming pool heating option. What’s more? The ground source heat pump works for a swimming pool just like any any other application - moving the heat from the region of a warmer temperature to the cooler temperature region.

Air source heat pumps are a type of heating system that you can use to warm the air in your property. They’re a semi-renewable energy generator as, although they use electricity, they extract and use renewable heat from the air.

There are two main types of air source heat pump – air-to-water, and air-to-air. Air-to-water heat pumps are the most popular, and are best used to heat water that supplies underfloor heating systems or large radiators. Air-to-air pumps heat air, which is then dispersed round your property using fans.

Do you want a low carbon way of heating your home? Then, getting an air source heat pump is the way to go! What they do is pretty simple - they absorb the potential thermal energy present in the outside air and transmit it directly to the home or property where it’s going to be compressed and the heat transferred with the help of a number of coils. In other words, it functions by extracting heat from a cooler place and then uses it to raise the temperature inside a home or property. Being very similar to air conditioning units, the amount of heat they’re going to produce for your home or property will be dependent on the size you install. Therefore, the bigger the heat pump, the more the heat that’ll be generated.

Air source heat pumps have two main types which includes air to air and air to water. Air-to-water heat pumps works by absorbing heat from the outside air, then relays it directly into your home or property through the help of fans. In order to move the heat around your home, you’ll need a warm air circulation system. This type of air source heat pump are not eligible for the government’s Renewable Heat Incentive Payment as they can’t generate hot water. What’s more? They can function in reverse during the hot summer months.

Air-to-water heat pumps, on the other hand, operates by extracting heat from the outside air and transmitting it into the wet central heating system. Due to the fact that they’re able to generate heat that’s cooler than the one generated by a conventional gas or oil boiler, they happen to be a better fit for larger radiators or water underfloor heating.

Not only will you reduce your electricity bill by generating your own electricity with solar panels, but you can also earn money through the SEG which is offered by large energy suppliers. They’ll pay you for the electricity you export back to the grid. You’ll also reduce your carbon footprint, lessening your impact on the environment.

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.
