Are Air Source Heat Pumps Noisy?

Tuesday 3rd May 2022

Devices which transfer available heat from the air surrounding a property are called heat pumps. An efficient pump will increase the temperature of this air to make it a useful source of energy for a home or property. All heating products make some sort of noise, but heat pumps are usually quieter than fossil fuel boilers.

Most Modern Heat Pumps Are Not Noisy
Heat pumps are issued in a wide range of sizes and shapes, which can ultimately have an impact on how noisy they are. Luckily, there are numerous government guidelines in place, which now mean that many modern air source heat pumps are much quieter than the older models.

What Might an Air Source Heat Pump Sound Like?
Depending on the type of installation, you can expect different sounds for different air source heat pumps. However, the most common sound is much like a very low whirring if they're working as they should be.

Your heat pump may make a louder, or more aggressive noise if there is a malfunction with the system. In this case, you should seek out advice from a professional heating engineer in your local area.

What is the life expectancy of an air source heat pump?

Thursday 17th February 2022

Firstly Air Source Heat Pumps are incredibly resilient and most manufactures offer up to 7 year warranty which is a huge plus. On average Air Source Heat Pumps last for between 10 - 15 years however many systems have far exceeded this time frame over the years.

Due to this long lifespan by the time you will require a replacement heat pump your system will have more than paid for itself and you will be in profit.

Heat pumps also last just as long, if not longer than a traditional gas boiler, they are efficient, and they ensure that your home is comfortable at all times.

With regular maintenance, you can ensure that your heat pump lasts for as long as possible and you don't have to worry about it failing on you.

It isn't hard to replace your heat pump and it is a a lot quicker than a full system installation as all of the other components are already installed. normally a heat pump only replacement can be completed within 1 day.

What is the difference between a boiler and a heat pump?

Friday 28th January 2022

Boilers have long been established as the conventional way in which the vast majority of homes are heated, and there is a very well-established industry providing boiler repair, in addition to vast numbers of heating engineers who are experienced in boiler service requirements, among other things.
In recent times, though, heat pumps have arrived on the scene as an alternative to gas and oil boilers, and they have been rapidly growing in popularity. So what are the real differences between boilers and heat pumps?

Heat pumps
The key benefit of heat pumps is that they are a source of renewable energy and have a significantly lower associated carbon footprint.
Heat pumps also have a significantly better COP (Coefficient of Performance) score than boilers, with each unit of energy put into the heat pump returning as much as three times the energy output as heat.
Heat pumps can also be installed under a new UK government grant scheme, where each household is entitled to £5,000 to install low-carbon heating systems.

Boilers are less energy-efficient when heat pumps are performing at their best.
Boilers run on gas or oil, and prices may be raised to meet the government's carbon targets.

Is a Heat Pump right for heating my house?

Thursday 15th December 2021

There is a lot of talk about heat pumps right now. Many people believe they are the best method to meet our climate change targets and get to net-zero by 2050. The government intends to install 600,000 of them into UK homes every year.
Heat pumps are undoubtedly efficient and will contribute to reducing carbon emissions.

How do heat pumps work?

An air-source heat pump resembles an air conditioning unit installed outside the residence; however, it works similarly to a refrigerator in reverse and functions as a boiler, in that it produces hot water. However, unlike boilers, heat pumps do not generate heat; instead, they transfer it from one location to another.

A fan unit is included with air source heat pumps, which draw heat from the outside air. After that, the heat is concentrated and used to make hot water. The hot water must be stored inside the residence in a hot water cylinder to feed radiators, taps, and showers. The system is powered by electricity, and copper plumbing connects the two units.

Is a heat pump suitable for your house?

A well-insulated dwelling with a garden is ideal for a heat pump. The correct heat delivery system and hot water cylinder can be easily included if the heat pump is integrated into the build from the start. Heat pumps and other renewable heating systems are set to become the default heating system from 2025 when connecting a new build home to the gas grid is no longer an option. Of course, not all existing properties are well-insulated, but it is advised to get this sorted ASAP as the benefits of a heat pump are plain for everyone to see.

Everything You Need To Know About The Government's Upcoming £5,000 Heat Pump Grant

Friday 19th November 2021

Following the closure of the Green Homes Grant earlier in 2021, the latest Government scheme to help build carbon-neutral homes has been revealed. But what exactly is the £5,000 Air Heat Pump Grant?

Our simple guide will answer all the key questions, including:

• What is the Heat Pump Grant?
• Who is eligible for the Heat Pump Grant?
• When does the Heat Pump Grant come into effect?
• What happens when the heat pump costs more than the limit?
• How do I apply for the Heat Pump Grant?

What is the Heat Pump Grant?
In essence, the Heat Pump Grant is a scheme that allows UK homeowners to apply for a one-off £5,000 voucher for replacing less efficient gas boilers with air-source heat pumps. The scheme is ready to launch in April 2022.

However, homes that need to source heat from the ground can have this increased to £6,000 so they can save even more.

What happens when the heat pump costs more than the limit?
The grant isn't designed to cover the full costs of an installation. In fact, the average household can expect to pay between £10,000 and £12,000. However, this should bring the costs down to the same level as replacing a gas boiler.

So, you get an eco-friendly and efficient upgrade at the cost of a standard upgrade package. In turn, this lets you save the environment as well as money.

Who is eligible for the Heat Pump Grant?
Most homeowners and landlords (public and private) can apply for the £5,000 one-off Government grant. The only notable exceptions are new build properties and social housing while the scheme is also limited to England and Wales.

How do I apply for the Heat Pump Grant?
With the scheme limited to 30,000 homes per year, it's advised that you apply early. However, it is not a grant that you can apply for directly through the Government. You will need a heat pump installer to act on your behalf to liaise with energy regulator Ofgem.

How does an Air Source Heat Pump work?

Saving money on your energy bills might seem like a real challenge. It can be without the right knowledge of what energy systems to use in your home. However, this post will assist you in an alternative way to heat your home, which can help you save money and live more sustainably.

You might wonder how exactly to achieve sustainability and money-savings when heating your home. The answer is an air source heat pump.
What is an air source heat pump?
An air-source heat pump takes in external air and uses a compressor to heat it up before releasing it into the home. They are a way to reuse natural sources and heat your home for less.
How does an air source heat pump work?
Air source heat pumps work by using a compressor to heat up natural air. Instead of using gas, they use natural air to heat the home.

The following steps will help you understand its process.

1.The air pump absorbs the outside air and turns it into liquid. The liquid is stored at a low temperature.

2.The air is then turned into hot air through compressing it, which is performed using electricity.

3.This heat is then sent to radiators and can be stored in a water heating cylinder. This stored heat can be used for showers, baths, and taps.

Although an air source heat pump uses electricity to work, it uses a lot less energy to heat the home than a gas boiler. It is a renewable and less expensive way to heat your home.

At home with a heat pump: 'It makes hot water when it's freezing outside'

Tuesday 17th August 2021 - AOS were featured in an article which appeared online in the Guardian newspaper.
Click here to read the full article

John and Carol Deed, Thriplow, Cambs

"We had an air source heat pump fitted in January 2020 and it has proven to be a really good decision," says John Deed, a former marketing executive in the car industry.

Deed and his wife Carol began considering home heating options for their detached four-bedroom 1970s house when it became clear their 25-year-old oil boiler was "on its last legs".

"We considered cost as well as environmental impact and this ruled out going with oil again - [it's] volatile in price, a pain for delivery and of course not good for the environment," he says. They settled on an electric heat pump to make the most of their green electricity tariff and planned solar panels, which they fitted over the summer. The house already benefited from cavity wall insulation, loft insulation and double glazing.

"The first pleasant surprise was how nice it was to have the whole house, which is about 1,700 sq ft, at 20 degrees all day, especially when Covid has confined us to our home for much longer than normal," says Deed. "The second pleasant surprise was the running cost."

After a hefty initial outlay, the couple's solar panels now generate more than enough electricity to run the Mitsubishi heat pump, compared with paying £900 a year for oil. The heat pump cost £14,000; the government grant of £8,400, to be paid over a seven-year period, leaves a net cost of £5,600.

"It's no more noisy than the boiler and quite how it makes piping hot water when the air temperature outside is freezing is a mystery, but we'll take that!"

How to save money of your energy bills

One of the biggest questions we have during adult life is how to save money on our gas, electric, and water bills at home. Being more eco-friendly is an important feat for us these days, but also saving money on our bills is an important thing to consider.
Today we are going to take a look at some of the ways you can save money on your energy this year.
Use an air source heat pump
If you have never heard of a heat pump before - this can be a useful tool to install on the side of your home. An air source heat pump will absorb heat from the outside and use this to heat up your home naturally. They can also be used to heat up hot water and this can make a massive impact on your heating bills.
Use less water
Using less water is one of the most important ways that you can save energy at home. It takes a lot of energy for water to be brought to your home, heated up, and then taken back to the plant where it is sterilised. By using less water each day, you can save a pretty penny and also do some good to the environment.
Choose an eco-boiler
These boilers are engineered to protect the environment while also providing you with the hot water you need to heat up your home. Choosing an eco-boiler is a great way to save money on your energy bills and they are incredibly efficient.

How An Air Source Heat Pump Works?

Using an air source heat pump to heat your home is more eco-friendly, more energy efficient, and can be highly cost-effective. Essentially, when using an air source heat pump, you can make your own - renewable - energy, thus saving money.
When you use an air source heat pump, the heat will be delivered to your home at a lower temperature than using an oil or gas boiler. Although this means such a pump will have to be run for a longer time to get up to the right temperature, it is still cheaper than using other kinds of heating. If you need to replace your boiler, a great way to make it more affordable to run would be to ensure the new boiler can use an air source heat pump. Of course, you'll still need to ensure your home is adequately insulated, otherwise you'll lose more heat than usual, however.
The air source heat pump uses a compressor that takes heat from the air and raises its temperature. Once it reaches the right temperature, the energy will be transferred to your heating system; this is essentially the opposite of how a fridge works. To get to the right temperature, the warm air is first turned into a cool liquid refrigerant, compressed, heated up, and turned back into liquid once it reaches a specific temperature. This liquid is your fuel which runs through your boiler and allows you to heat your home and hot water. You can safely store anything you don't use.

You will need to use energy to make the pump work since it requires power, but when you offset this energy cost against the savings you can make using the air source heat pump, you should still save money using this eco-friendly method of heating a property.

How hard water can affect my heating system?

Soft water has a low content of calcium carbonate, magnesium, and other minerals. Hard water contains a high amount of these substances. The large majority of homes in England have a hard water system. It's fine to drink water with a high mineral content, but it's not the best water for a heating system.

How might hard water affect my heating?

Calcium and magnesium turn into hard deposits of limescale. These cause damage to the water system because they cause blockages. When your heating system is full of limescale your system has to work harder to heat your property. The result is often that the system overheats and eventually breaks down. At first, you might notice that your water doesn't get very hot, or that the pressure is low.

Hard water causes various problems including:

• Your home will be less energy efficient.
• Your bills will be more expensive.
• Your property may be too cold.
• The water pressure may be too low.

How can I improve my heating system?

To improve your heating system, use a limescale remover to descale your boiler. If you're still having issues it's best to call in the experts. Heating engineers can provide many different solutions, to remove hard water from your heating system. To remove limescale from your radiators and pipes, you may require a 'power flush'. The solution works by flushing a mixture of water and chemicals through your heating system.

What are Heat Pumps?

An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. the system extracts heat from the air even when the temperature is as low as -15° C. Heat pumps require electricity to run, but the heat they extract from the air is constantly being renewed naturally.
Heat pumps come with multiple advantages for your home. Pumping the heat uses less electricity as compared to when electricity is solely used to convert it. During the summers, the cycle can be reversed and the unit acts like an air conditioner.
Heat pumps are rising in popularity in the UK, and the government recently started to implement a number of new schemes, incentivising the transition to green living and alternative energy usage smoother and more affordable.
By combining heat pumps with solar panels, you can make your home self-sufficient and eco-friendly. Properly designed and installed heat pumps can be worth it, by regularly attain more than 300 per cent efficiency.

The difference between hard and soft water

We all use the terms "hard" and "soft" to describe the water that comes out of our taps, but the truth is that many of us don't actually know what that means. Plenty of people wonder what the difference is between the two is and whether or not there are any issues associated with these different types of water. The difference between the two is actually very straightforward. The hardness or softness of water is measured by the levels of certain minerals contained within it.

Hard Water

Hard water is water that contains high levels of calcium and magnesium. This might sound concerning but it isn't going to cause any real problems for your health. That said, you may notice minor things like slightly drier skin or an itchy scalp after washing your hair with hard water. You may also find that the hardness of the water can cause your clothes to wear out more quickly and leave calcium carbonate deposits on glasses and dishes after you've washed them. Water softening systems are designed to filter out these minerals.

Soft Water

Soft water is water with higher concentrations of sodium, or salt. This means that using soft water is often slightly better for your skin. Your clothes will often last longer using soft water and you won't find any mineral stains on them. You may also find that the water pressure in your home is more consistent because soft water doesn't leave mineral deposits in the pipes in the same way that hard water does.

Mitsubishi Electric Case Study

Nigel Furr from Buckinghamshire has become the latest homeowner to move his property
away from oil-based heating to a renewable air source heat pump

Undertaking a property wide conversion, taking his two-bed bungalow to a four-bed chalet bungalow, Nigel decided to make the move to a renewable heating solution after the positive feedback he had received from other local homeowners who had already made the transition from oil to a heat pump.

"After talking to our neighbours, many of whom had been using oil previously, we researched air source heat pumps as a solution that was better for the environment and would also help us cut our energy costs." said Nigel.

Following a conversation with Mitsubishi Electric, Nigel was put in contact with their Business Solutions Partner, AOS Energy Efficient Heating Systems Ltd, who suggested an Ecodan
Heat Pump as a viable alternative to oil.

"As a Mitsubishi Electric Business Solutions Partner, we are confident that their products,
aftercare and back-up services are the best in the market," said Lee Wildego, technical surveyor
and contracts manager, AOS Energy Efficient Heating Systems Ltd.

"We have installed nearly 600 heat pumps over the last seven or eight years and each year the number we install is increasing. Homeowners are really starting to see the benefit of air source heat pumps and the calls we receive from new leads shows the understanding of the technology and benefit behind it."

With no access to the gas grid, Nigel decided not to install an unsightly and potentially dangerous oil tank on his property. The Mitsubishi Electric Ecodan 11.2kW was therefore the perfect alternative, with low maintenance and quiet running as recognised by the Noise Abatement Society.

Despite it being unlikely that Milton Keynes will be affected by significantly cold weather, Nigel is comforted in the knowledge that the Ecodan will be able to operate in outside temperatures as low
as -20°C. As a self-contained unit, only requiring water and electric connections, the Ecodan installation ensured that the renovation project was not delayed. Adopting the ultra-quiet version also means the heat pump doesn't emit noise levels above 53 dB(A).

Why your home might not stay as warm as it used to

If your home no longer stays as warm as it used to, then things can get pretty uncomfortable pretty fast. And that's before you even consider that this could be the prelude to a total boiler breakdown!

Where lost heat is concerned, you obviously want to think about external factors first. After all, gaps, single-glazed windows and faulty draught excluders are all some of the worst culprits for lost heat. If you're sure these issues aren't to blame, though, you'll want to look a little closer to your central heating itself by considering potential issues including -

Boiler malfunctions

Boilers themselves aren't bombproof, and issues here are guaranteed to trickle into your heating capabilities. Some of the primary problems with boilers include -
• Inefficiency due to excessive wear
• Faulty parts (mainly pumps and valves)
• Performance problems due to overuse

Each of these can result in an unsafe boiler setup, and a significant risk of breakdown if you don't turn to the professionals for repair sooner rather than later.

Radiator problems

Radiators can also be prime no-heat culprits, with everything from clogging to leaks preventing heat from spreading. It may be that you notice your radiator is only hot in certain areas, or perhaps it fails to heat up at all.

Again, experts are your best bet for overcoming this problem, as they'll be able to inspect not only the issue but also its source. And that's the best chance you have at enjoying heat again in no time.

What to Do If Your Water Pipes Freeze

The ideal approach to dealing with freezing pipes is to anticipate the issue when winter approaches. However, when the unthinkable occurs, you will need to act quickly to limit the extent of damages and reduce the cost of fixing. Although it's safer to refer to a professional, you can keep these tips in mind to thaw your frozen water pipes and avoid extensive damage. Here is what to do.
1. The first step is to keep your tap open to allow the melting water to pass. When you begin the thawing process, the water and steam generated will require an opening to allow discharge. Doing this would prevent a leak from occurring.

2. Apply heat to the frozen pipe by wrapping an electronic heating pad around it. You can also use towels soaked in hot water. When you are using an electronic heating pad, never leave it unattended to avoid any fire outbreak.

3. Keep applying the heat until the water starts flowing like normal. After effectively defrosting your pipe, turn on the faucets in your home to check for any other frozen water pipes.

4. Frozen pipes behind the walls can be difficult to melt and may require expert help to repair. However, to offer an immediate solution, you can increase the temperature in your home to make it warmer for pipes to thaw till help arrives eventually.

5. Avoid using kerosene or propane heaters or a blowtorch to defrost your pipes. Avoiding these will save you from any unwarranted fire hazards.

How to save money on your gas bill

If you're trying to cut costs at home, then your gas bill is a good place to start. The gas bill is often one of the highest home costs, but there are some things you can do to lower your gas bill, without having to make big or expensive changes to your home.

1. Turn down the thermostat. Dropping the temperature by only one degree can save energy and money, without feeling any difference.
2. Don't dry clothes on your radiators. Covering the radiators lowers the amount of heat that the radiator can release, meaning the boiler has to run for longer to get the room to the same temperature, using more fuel.
3. Use a hot water bottle at night. It's much cheaper than leaving the heating on.
4. Switch to a different supplier. You might be able to find a better deal, especially if you've been the same supplier for three or more years. You could also use a lower quote to negotiate with your current supplier.
5. Move your furniture away from your radiators. The foam that is in upholstered furniture works an insulator, preventing the heat from getting into the room.
6. Use the sun. This is the most readily available source of heat, and the cheapest. When the sun's out, make the most of it by opening internal doors and letting the warm air move through the house.
7. Draw the curtains at night to keep warmth in and cold out. Tuck your curtains behind your radiators so you don't lose heat out of the window.
