Most domestic solar thermal panels do not need planning permission and are covered by permitted development rights. There are restrictions on the size and location of these systems. If you live in a conservation area or listed building, or want to install a very large solar thermal system, check with your local authority to see if you will need planning permission.

Solar panels provide an alternative to paying expensive National Grid energy rates, so primarily their first major benefit is helping to reduce bills. Solar PV panels will produce free electricity, whilst solar thermal panels generate heat for hot water and space heating. There are also payment incentives known as the Feed-in Tariff scheme (FITs) (for solar PV) and the Renewable Heat Incentive (for solar thermal) which guarantee a tax-free income for 20 years.

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.

If you’re looking to install a solar thermal system in your home, this is usually one of the first concerns several homeowners have. Being fully aware that solar water heating systems are usually more expensive than their counterparts - the conventional water heating systems, the question arises whether or not you’ll be able to save some money from your solar water heating system in the long run. In this article, we aim provide an answer to this important question. Let’s take a closer look!

When it comes to solar thermal systems, the money you’ll be able to save in the long run depends on a wide range of factors. These factor includes:

✓ Your system’s performance.

✓ Your geographical location and solar resource

✓ Your household’s hot water demand

✓ Financing and incentive options that are available.

✓ The cost of fuel that’s being used for your alternative or backup water heating system, if you own one.

✓ The cost of conventional fuels such as oil, electricity or natural gas.

There are several benefits, however, that comes with the installation of a solar water heating system. Since the sun is absolutely free, future fuel shortages and price hikes will have little impact on you. Also, on the average if you decide to fit a solar thermal system your water heating bills is expected to drop about 50 percent to 80 percent. What’s more? The economics are even a lot more attractive when you’re just about to build a new home or refinancing. When you include the price of a solar water system in a 30 year mortgage, it’ll normally amount to very low price per month. Therefore, on a monthly basis you’ll be saving more and paying less.

Asides from the fact that solar energy can be converted into electricity with the help of solar panels, there’s also another pretty cool way the sun’s power can be harnessed - solar thermal technologies. These technologies are able to convert sunlight into heat rather than power and these are in fact the very first solar energy products that were commercialized in the United Kingdom. Solar thermal panels, in a similar way to solar PVs, can help in minimizing your carbon footprint while also assisting you to save good money on your energy bills by providing the much needed coverage for your heating needs with the help of a renewable energy source that’s totally free.

Solar thermal panels provides some great benefits which is capable of making all homeowners in the UK consider installing one in their respective homes. Let’s take a closer look at these benefits.

✓ When compared to solar PV panels, they’re a more affordable heating option and also have a shorter payback period.

✓ Solar thermal panels are more efficient than PV panels due to the fact that the heat waves are able to hold more energy than sunlight and also because there’s no electricity transformation process.

✓ Solar thermal panels are able to operate in cold climates, strong wind as well as overcast weather, and make use of an energy storage system.

✓ They can help you save about 600kg of carbon dioxide emissions on an annual basis.

✓ Although most of the solar thermal panel systems come with a warranty usually within the range of 5 to 10 years, they’re able to last up to 25 years. What’s more? The require just a little maintenance, meaning the main cost you’d have to worry about is the cost of installation.

Air source heat pumps can be a really efficient way to generate heat. Although they require electricity to run, they generate much more heat than an electric heater that uses the same amount.

Air source heat pumps provide heat at a lower temperature than most other types of space heating. This means they’re most efficient when they’re left on for longer periods of time, and distribute heat through wet heating systems with large surface areas, like underfloor heating or big radiators.

Air source heat pumps can be much more efficient than oil and LPG boilers, and older electric heating systems. However, they’re only usually the most efficient option if your property is very well insulated.

If you’re considering installing ground source heat pump, it’s likely you’re also wondering just how deep it’ll go into the ground to be efficient. Well, the initial step to take while determining the ground source heat pump’s design is to research the different options available to reduce the space heating as well as hot water demand. To achieve this, there must be an accurate measurement of energy efficiency which is usually done by getting an Energy Performance Certificate ( EPC) . This is helpful as such that it helps to identify the most suitable or the right size of heat pumps which will help reduce the consumption of energy, heat loss as well as hot water needs of the house.

Generally, ground source heat pumps are usually more compatible with new builds against retrofits. What’s more? The heat pump has two different types of loop systems :

✓ The open loop system and;

✓ The closed loop system.

The open loop system absorbs water from the ground and transfers this ground water via a heat pump to where it carries out the extraction of heat. Meanwhile the closed loop system extracts heat from the ground and incorporates a continuous loop of piping that’s linked to the indoor heat pump. There are a few types of closed loop system, these includes:

✓ The Horizontal Ground Source Heat Pump. This is installed in horizontal trenches of about 1 to 2 metres deep. This is more common in areas where land is readily available.

✓ The Vertical Ground Source Heat Pump. These boreholes are a more costly option but it’s also the best option when land is not readily available for horizontal installation. The insulation hole is dug at a minimum of 6 metres into the ground, while the entire piping will be at a depth of about 50 to 150 metres based on your home’s heat requirements as well as the ground’s composition.

If you happen to live in a quiet, serene environment ( or just cherish being in one) and wish to have an air source heat pump installed on your property, then you’d probably want to know just how noisy these renewable energy source are. In this post, we aim to provide answers to this question and more. Let’s take a look!

There is no short and direct answer to this question as air source heat pumps are available in varying shapes and sizes which makes the sound as well as volume of their noise different between models and manufacturers. However, as a result of government regulations, most of the contemporary air source heat pumps are able to function a lot quieter when compared to the older models. As you would have expected, modern air source heat pumps shouldn’t produce more than a low whirring sound provided they’re functioning as they should with no faults. On the other hand, the volume of the sound generated is largely dependent on the amount of work the air source heat pump is doing. This implies that a greater work load will generate a louder noise. This is due to the fan’s speed which works to absorb warm air into the compressor.

In order not to disturb the neighbours, noise pollution is normally determined at the design stage of the air source heat pump installation. The unit to be placed outdoor will typically be positioned as far from the neighbours property as possible and it’s also a great idea not to put the box directly under any windows. Overall, it’s always advisable to go for the newer models which tend to be better designed with thicker chassis and quieter fans.
