MCS Accreditation is an industry-led quality assurance scheme for ground source heat pumps.
The Microgeneration Certification Scheme (MCS) standards assure the ASHP installers are qualified and can demonstrate compliance with industry standards.
Being MCS certified demonstrates to customers that you are a reliable engineer with the ability to install approved ASHP products and specifications.
Air source heat pumps work by absorbing air from the outside and transferring the heat into an indoor space. It comprises the air source heat pump placed on the side of your property and a series of pipes installed inside the building.
It starts with the box placed outside your house or your building. This air source heat pump sucks in air from the outside and blows the air through a series of tubes and pipes filled with a refrigerant. This increases the temperature of the refrigerants, warming it up to turn the liquid refrigerant into gas.
The gas made from the liquid refrigerant then passes through a compressor that applies and increases pressure. This air compression further increases the temperature of the gas, making it even warmer.
After this, the compressed gas passes through a heat exchanger surrounded by either cool air or water. The heat exchanger warms up the surrounding air or water, which then circulates around your home as heated air or heated water.
When the gas refrigerant is cooled after the heat exchange, it condenses back into a liquid refrigerant. It circulates back to the beginning of the system to be reused again.
Some ASHPs can also convert hot air into cool air and are used in air conditioning.
During the winter and the colder months, ASHPs absorb heat from the ambient heat that is still available. Though the heat pump can still produce heat during the winter, it may take more electrical energy to produce the same amount of heat as during the warmer seasons.
The temperature in Merton stays above 10°C. Air source heat pumps can work well within this temperature. But if you live in much colder places than the UK, it may benefit you more to invest in a ground source heat pump because the ground temperature in these areas may be warmer than the air temperature.
Air source heat pumps can still function longer and more efficiently during the colder months when regularly cleaned and maintained by professionals like us. If we work together to make sure that your air source heat pump is serviced every 12 months, it can last for as long as seven years to up to 20 years.
Air Source Heat Pumps installation costs range from £3,000 to £18,000, depending on the type of air-source heat pump technology you want to be installed and the brand you choose.
Between the two types of ASHPs, air-to-air heat pumps are the more affordable option, averaging around £3,100 for the heat pump system and the installation costs.
Meanwhile, if you have the budget set aside for the heat pump installation, you can opt to go with air-to-water heat pumps that cost an average of £13,000 for both supply and the heating system installation.
One of the biggest challenges that prevent homeowners from installing an ASHP is the price. However, suppose you consider the long-term benefit of the heating system to the environment. In that case, it turns out to be the more cost-effective alternative when compared to conventional heating systems.
At Air Source Heat Pump, we can assist you with the best options available. Make sure you contact us today for a number of great ASHP services in Merton.
Installing an air source heat pump into your home can be a big commitment. When computing the total costs of installing an air source heat pump, take the following factors into consideration:
Usually, the running costs for an ASHP average at £560 per year. This estimate is computed from the average consumption of homes within the UK which is 12,000 kWh of heat per year.
Most air source heat pumps will use up to 4,000 kWh of electricity to produce 12,000 kWh of heat.
After installing the air source heat pump, the next things you should consider are the running costs. The running costs include how much money you have to spend monthly and yearly to keep the ASHP running.
Several factors can affect the running costs of your ASHP. These factors are heat demand, the ASHP efficiency, and the room’s insulation.
Compared to a traditional heating system, ASHP is still the most cost-effective alternative.
Air source heat pumps are easy to maintain. Unlike traditional heating systems that use corrosive and dangerous materials throughout the fuel deliveries to supply combustion-based heating, ASHP systems only use air.
Because the entire air source heat pump system is simple and effective, it only needs occasional servicing and maintenance checks from the owner and professional technicians.
After the ASHP has been serviced by our professionals, they should issue you a service certificate as proof.
Most ASHP brands offer a 5-10 year warranty on both the parts and the service labour. However, well taken care of, ASHP systems can last much longer than the services warranty.
An air-source heat pump manufacturer offers a warranty required to provide every year.
The Renewable Heat Incentive (RHI scheme) also requires that the ASHP unit operate effectively and maintain through annual servicing.
Here are the main air source heat pump manufacturers we purchase from:
As of December 1st, 2011, air-source heat pumps are considered permitted developments. You do not need to apply for a planning permit installed on domestic premises. However, you need to make sure that all of the following conditions are met:
If the Microgeneration Certification Scheme Planning Standards are met by the air source heat pump installation (MCS 020)
The ASHP outdoor compression unit volume must not exceed 0.6 cubic metres. Only the first ASHP installed is permitted development. Additional turbines or ASHP in the area need a separate permit. The ASHP, all of its parts, has to be at least one metre away from the property line boundary.
The heating pumps are not permitted to be installed on pitched roofs. If the pumps are installed on top of flat roofs, all parts of the air source heat pumps need to be at least one metre from the outer edge of the roof.
Installations inside the curtilage of a Listed Building or on a Scheduled Monument site are not subject to permitted development rights.
The air source heat pump cannot be put on a wall or roof that faces a roadway or be closer to any highway that borders the property than any other portion of the structure on territory inside a Conservation Area or World Heritage Site.
The air source heat pump cannot be built on a wall that faces a roadway, and any portion of that wall is above the ground floor level on land that is not inside a Conservation Area or World Heritage Site.
We offer a number of great Air Source Heat Pumps and are more than happy in assisting you on anything you need more information on.
Air source heat pumps offer many advantages. Unlike gas or electrical heating systems, the air source heating pump helps you reduce your energy consumption.
Air source heat pumps save space and are fully automated. Because they use air, there is no need to store and manage fuels, and there is no risk of stealing the fuel. There is also no combustion danger.
Heat pumps also save on carbon emissions by not having any carbon emissions. Heat pumps also come in handy all year round, producing heat energy through the colder months and cooling in the summer.
The biggest benefit of installing an air source heat pump is the Renewable Heat Incentive or the RHI scheme. The RHI scheme is a financial incentive for commercial building owners and administrators to shift to renewable energy and install air source heat pumps.
An air source heating pump can normally be installed within 2 business days. Installing an ASHP is more efficient than ground-source heating pumps and generally does not need planning permission, but it is still best to get in touch with local authorities to be sure.
Air source heating pumps are installed more efficiently than a ground source heat pump because no digging is required, making it easier to integrate the air source heat pump installation into the retrofitting or the construction of a new building. This integration can lower the costs of the installation.
The effectiveness of heat pump systems is measured with the power converter. The power converter determines the output of the ASHP. During both the winter and the summer, the air source heat pump work with high temperatures, and the air source heat pumps run at COP 3.2 in an air environment when the temperatures go above 70C.
This generates 320% of the consumed energy through the ventilation unit and the compressor. The COA figures are adjusted for seasonality, with greater percentages translating to a more efficient system.
The Renewable Energy Incentive may pay you for utilising heat generated from renewable sources, and green energy subsidies might help you save money on your power bills. The deadline for air-cooled heat pumps has been extended to March 2022.
Current RHI rates, the SCOP of your heat pump, and the energy consumed for your house are used to determine the Domestic RHI Payment. RHI incentives are available for some heating systems.
The cost of running a heat pump is determined by several factors, including efficiency, temperature, necessary heat, temperature, and power source. You will save money on your energy bill if you choose to use heat pumps heated using air.
Switching from electric to coal-fueled systems will save you much more money. However, if you pay the RHI beforehand, you might reap huge benefits. Up to £335 can be saved by using air source heating pumps.
Depending on the type of air-source heat pump you have, you could even be able to heat some water, allowing you to use it for space heating and hot water. This is determined by the heating system’s temperature or the velocity of flow.
The water must flow at around 55 degrees Celsius to hold heat, and it will have a maximum temperature of 35 degrees unless you employ a heat exchanger for space heating. The ASHP is a heating system that combines space and water heating and requires a flow rate of 55 degrees Celsius or greater.
Air-source heat pumps are quite handy in Merton when it comes to heating and cooling. Air source heating pumps are excellent for heating and cooling, with the model determining whether they can provide heat in the winter and cool in the summer.
According to the model, the air conditioning unit is heated in the winter and chilled in the summer. For a cooling fan, the COP needed is just approximately 0.75. A circulating air source heat pump may also be used to install underfloor heating; therefore, it’s a good idea to do so if you have the option.
It is recommended to have an air source heat pump that is circulating installed in your home for underfloor heating since it is a great option for floor heating.
Outside air is used to heat and cool the residence with air source heating pumps. Choosing a coal-fired heat source is an excellent strategy to lower your carbon footprint.
Electricity accounts for just 1% of the total energy consumed by an air source heating pump.
Technicians undertake maintenance every three to four years. Although air sources are low-maintenance, you can ensure that your heat pumps perform at their best.
Only an approved installer will be able to certify any technical work.
Air source heat pumps do not store any fuel. For example, when using oil-burning boilers, an empty container must take up more room.
You can’t afford a full petrol tank if you don’t use gasoline or wood pellet fuel.
Air Source Heat Pumps have a longer lifespan if properly maintained, lasting up to 20 years. A warranty period is included with almost all air source heat pumps.
For approximately 25 years, modern heat pump technology has been created.
There are two different types of air-source heat pumps: ‘air-to-air’ and ‘air-to-water’. The main difference is the end product that heats up your home.
Air-to-Air heat pumps warm your home through heated air distributed through a fan, while Air-to-Water heat pumps can provide hot water for heating, your radiator, or your underfloor heating system.
The majority of air source heat pumps installed in the UK are air-to-water types.
Air conditioning is a term used to describe air-to-air heat pumps. While most people associate air conditioning with cooling, it may also heat buildings.
Heat is transferred from the outside air to the air within your home via air-to-air heat pumps, raising the temperature in each room. This warm air enters your house through a succession of fan coil units.
Because an air-to-air heat pump does not heat water delivered to the taps, you’ll need to find another means to heat water for showers and baths.
With air-to-water heat pumps, heat is transferred from the outside air to water via an air-to-water heat pump, then heats your rooms via radiators or underfloor heating. Heat is absorbed into a fluid from the air. After that, the fluid goes via a heat exchanger into the heat pump, which raises the temperature and then transfers it to water.
It may also heat water that has been stored in a hot water cylinder for use in your heat radiators, hot taps, showers, and baths.
Air source heat pumps are great alternatives for heating up your home with minimal energy required. Though it seems like air source heat pumps are nothing but good, it still has a handful of disadvantages that you have to consider.
The disadvantages of air source heat pumps vary depending on the heat pump you want to work with. In general, here are some of the disadvantages you can expect to encounter with air source heat pumps.
When the temperature rises above freezing, an air source heat pump may cover all your heating and hot water needs. Decreased temperatures outside of your home, on the other hand, might mean lower heat output from the heating system, so having a backup heating system is a smart option.
As the outside temperature drops, the heating capability of the air source heat pump falls as well. The air source heat pump is designed to provide heat for 80-90%of your yearly load, and it should be able to meet 100% of your home’s heating needs while temperatures are above freezing.
This is why having a backup heating source ready for when the outside temperature lowers is suggested. When your air source heat pump starts to lose efficiency, it will be able to take up the slack.
If you take good care of your heat pump, it will last longer. Every 12 months, you should get your system serviced. Not only will this ensure that everything runs well, but you’ll also feel more at ease knowing that your heat pump will keep your home warm throughout the winter.
If you have an air source heat pump, you should clean any debris from the area to avoid clogging the airflow. The heat pump’s efficiency may suffer as a result of this. You should also check the filter regularly and replace it if necessary; any maintenance should be done by a skilled professional.
The UK government is giving various awards to encourage individuals to invest in low-emission heat pumps, including the Boiler Upgrade Scheme, which will give households up to £5,000 off the cost of heat pumps.
The household Renewable Heat Incentive (RHI) is another major award available in England, Wales, and Scotland, and it compensates for the energy your new system generates over seven years. Still, it will be replaced by the Boiler Upgrade Scheme by April 2022.
The Clean Heat Grant is a government-run program in the United Kingdom that aims to assist existing small household buildings in transitioning to low-carbon heating systems. The program will begin in April 2022 and will be expected to replace the Renewable Heat Incentive (RHI) when it expires in March 2022.
The major goal of this program is to minimise carbon emissions released by homeowners that still use fossil fuels to heat their houses, allowing fossil fuels to be phased out in the future years. This plan will help the government meet its ambitious goal of installing 600,000 heat pumps per year by 2028.
As a renewable heating specialist, we provide the following services in Merton:
We are a nationwide UK company that can also provide installations for water source heat pumps, ground-source heat pumps and a full range of air conditioning, gas boilers, installations of larger radiators, underfloor heating and fan coil services.
An air-source heat pump uses a small amount of power, although it is true that electricity is one of the most costly fuels, costing 14.4p/kWh compared to 4.17p/kWh for gas.
An ASHP can create 3 kWh of heat for every 1 kWh of power it consumes so the heat pump will need 4,000 kWh of electricity to provide 12,000 kWh for the average home, at £560 per year.
The length of time it takes to install a heat pump system is determined by the size and kind of heat pump.
On average, it takes between three to five days for two plumbers to complete the installation of the pipes, after which an electrician will spend up to three days installing the wirings.
The size of the heat pump is usually dictated by the size of the property. Normally, a 4kW ground source heat pump or a 5kW air source heat pump is needed for a 100 square meter home.
For 200 sq m properties, this increases to 8kW or 10kW.
Heat pumps have a very long lifespan. Their typical life expectancy used to be approximately 15 years, but because of several technical advancements, contemporary units now survive roughly 20-25 years before needing to be replaced.
It is always best to consider your current circumstances and the prospect of making improvements before buying and committing to an air source heat pump.
Your available space is always the biggest factor to take into consideration. The outdoor module of air source heat pumps, mounted on a wall or directly on the ground, requires some space.
It is important to remember that the system requires some room to maintain a decent airflow. As a result, installing an air source heat pump near a sunny wall is advisable.
You should also think about how well insulated your house is. When a home is effectively insulated, heat pumps perform better.
To get the best degree of efficiency for your air source heat pump, make sure your home is properly insulated and draught-proofed.
Consider the existing energy source and the fuel it consumes. If you now heat your house with electricity or coal, an air source heat pump will pay for itself considerably faster.
You should also consider the heating systems that are installed on your property. Because of the lower water temperatures required, purchasing an air-to-water heat pump might be more effective when combined with an underfloor heating system or warm air heating.
Using an air source heat pump in conjunction with other greener solutions may be beneficial.
A backup system or a system that boosts the heat pump’s performance will be available. You may use an air source heat pump with a condensing boiler, while it isn’t required.
The potential savings of around £2800 over the next 10 years makes an Air Source Heat pump an attractive option. This is especially true when there is a new Boiler Upgrade scheme in April 2022.
When selecting a heat pump, there are several aspects to consider. You must consider the prices and efficiency of each system and the ease of installation and the amount of space available on your site.
These two types of heat pumps have distinct configurations and needs, despite their similarity in functioning. Both include energy-saving features that might help you save money and heat your house more efficiently.
It may be easy to pick between an air source and a ground source heat pump if your budget or space is restricted, but others may need to spend more time to thoroughly assess their household’s demands.
It may be easy to pick between an air source and a ground source heat pump if your budget or space is restricted, but others may need to spend more time to thoroughly assess their household’s demands.
Solar Panels use the heat from the sun that warms a liquid in the collectors of these solar panels, which are mounted on a roof.
This liquid is then pumped through a wet central heating system or into an immersion heater within a hot water cylinder, where it heats the water in the residences.
ASHP systems, on the other hand, contain an outside fan that takes in air from the outside, and a heat exchanger then warms the air even further.
In the argument between heat pumps and gas boilers, you’re comparing two quite different technologies that offer the same result: hot water and central heating.
A boiler will create a large amount of heat with a large temperature differential in a short period. As a result, a boiler can function with radiators at a very high temperature.
On the other hand, a heat pump produces heat more slowly and with a smaller temperature differential. Because of the heat pump’s low temperature, the radiator (or emitter) must have a substantially greater surface area. In fact, it is now a ‘convector’ rather than a ‘radiator.’
Electric boilers are less expensive than air-source heat pumps (ASHPs), but they use three times as much energy.
Electric heaters and accompanying electric control components make up boilers, often known as furnaces. Electric heating with output steam, high-temperature water, or an organic heat carrier with specific heat energy is the most common.
A sort of HVAC equipment is the ASHP. With three functions in one unit, it can provide heating, cooling, and hot water for everyday usage, depending on the demands of consumers. The purpose of an electric boiler is pretty straightforward: it merely heats the water.
Users must, of course, pick their own heating items based on their own financial circumstances owing to investment cost limits. Because the safety coefficient of an electric boiler is quite low, we must select a major brand with assured after-sales service when purchasing.
A competent manufacturer with many years of expertise is preferred when selecting an air source heat pump.
Yes, air-source heat pumps work perfectly with radiators, providing very low flows of heat.
Existing radiators can often have sufficient capacity to lower the flow of air, especially when improvements have been made to the energy efficiency of buildings.
Heat pumps, on the whole, are not loud. On the other hand, heat pumps are generally quieter than fossil fuel boilers.
A ground source heat pump’s noise level can reach 42 decibels, whereas an air source heat pump’s noise level can range from 40 to 60 dB, depending on the brand and installation.
Ideally, no, you cannot install an air source heat pump inside the house since it will essentially convert the space into a refrigerator. It will continue to chill the same air until it cannot remove any heat.
Yes, air-source heat pumps are usually mounted on one of your home’s outside walls, and the exterior unit will be wall-mounted or set on a pedestal on the ground.
Ensure that there is good airflow and plenty of empty space wherever the air-source heat pump is installed.
It is vital that you get a registered MSC certified installer to fit your Air Source Pump.
Heat pumps are devices that move hot air from one place to another in order to heat the building in the winter, and for cooling in the summer.
The process works even at low temperatures since there is always heat to be sourced.
This system doesn’t require air pipes. It consists of some outdoor and indoor units called heads that allow air blowing, and are fixed on the wall as bathroom fans.
The splits are independent and can be turned on or off at need.
Depending on the complexity of the system, the price can range from £7,000 to £40,000.
It is not easy to forecast the exact price for it, as there are many different details to consider.
Yes, it is possible as most of the devices can be set to work only at defined times.
Below I have listed some of the important benefits of having loft insulation installed?
Energy Saving Trust provides leadership and expertise to deliver a zero-carbon society.
They work with individuals, businesses, communities and governments to save energy and reduce carbon emissions.
Below I have listed a few of the types of Government Grants and Schemes:
You are maybe eligible for grants to support energy efficiency home improvements under the energy company obligation (ECO) scheme.
If you are interested in moving to a greener heating system the boiler upgrade system (BUS) provides grants to cover your upfront costs.
Payments for producing electricity using renewable technologies under the smart export guarantee scheme.
If you’re 65 years old or more, you could get between £100 and £300 to help pay your heating bills.
If you get certain benefits you may qualify for a £140 discount on your electricity bill this winter.
If you get certain benefits you may qualify for payments when the weather is particularly cold.
Heat pumps are much cheaper than an oiler boiler because heat pumps generate energy organically and don’t use fossil fuels, they are a lot cheaper than oil.
An oil boiler is extremely energy efficient because they only heat water on demand rather than having a stored backlog. This means the energy output would be reduced and saves the amount of fuel required.
Running costs of an oil-fired boiler are usually lower than electric boilers. That is because oil is a much more efficient fuel than gas, so it gives a larger return on every unit of energy.
Oil boilers give the homeowner the opportunity to change supplier at any time as there are no contracts in place with a mains gas supplier, we suggest that you get your oil boiler checked as studies show a new oil-fired boiler with has an efficiency of 92-95%, compared to 60-70% in the case of older systems.
You can reduce your heating bills by switching to a heat pump, an air source heat pump works at around 300% efficiency and a ground source heat pump works at around 400% efficiency, so you will use less energy when heating your home, reducing your heating bills.
