What is the Best Heat Pumps, Brands & Pricing?

There are two different types of heat pumps:

• Ground Source Heat Pumps
• Air Source Heat Pumps

What’s the difference?

Air Source Heat Pumps: The most prevalent type of heat pump is the air source heat pump, which transfers heat between your home and the outdoor air. Similar to how a fridge extracts heat from its interior, an air source heat pump extracts heat from the air outside your property.

Operational in Cold Conditions:

Air source heat pumps may become less efficient as the outside temperature drops, but they can still function adequately in temperatures as low as -15°C, which covers the vast majority of the year in the UK.

High Energy Efficiency:

These pumps boast impressive energy efficiency ratings. While they do require electricity to operate, they do not directly combust fuels, thereby offering an effective means of reducing your carbon footprint.

Ground Source Heat Pumps:

Ground source heat pumps operate similarly to air source heat pumps but draw residual warmth from the soil or a nearby water body, transferring it into your property.

Lower Operating Costs:

Although installation costs may be higher, ground source heat pumps generally have lower operating costs due to their ability to rely on more consistent source temperatures. Like air source heat pumps, they possess excellent energy efficiency ratings and contribute to lowering carbon footprints by utilizing electricity rather than directly combusting fuels.

As per some recent Boiler Guide Articles please find the best heat pumps from each type:

What is the Best air source heat pumps and prices?

Typically, air source heat pumps for an average property range from £4,000 to £11,000*. However, it’s worth noting that in the UK, you can currently receive a £5,000 contribution towards the cost.

Efficiency: While this initial cost may seem significant, it’s important to consider that over approximately 20 years, it can efficiently heat your home while reducing heating bills. In the long run, the investment can pay for itself.

To provide a quick overview of the available options, refer to the table below before we delve into more detailed information about each model individually:

Comparing air source heat pumps:

When trying to choose the best air source heat pump for your home, there are several key features to consider apart from the price.

What Types of air source heat pumps?

There are two types of air source heat pumps to choose from air to water or air to air.

• Air to water heat pumps are the most popular as they pride heating and hot water.
• Air to air heat pumps are less popular, as they only provide space heating and not hot water production.

What is the difference between monobloc or split heat pumps which refers to how the system is set up in your home?

• A monobloc has all of its components (apart from the hot water cylinder in your home) in one compact unit outside the home.
• A split heat pump includes an outdoor with the heat exchanger and refrigerant as well an internal unit inside.

Most homes in the UK are ideal for a monobloc air to water heat pump, but a split system may be suitable for more complicated installations as it can be installed up to 30m away from the home offering a more flexible installation.

Energy Efficiency:

Air source heat pumps are exceptionally efficient, as for every kW of energy they use, they generate three times as much usable heat.

While some heat pumps may be labelled with better efficiency ratings than others, it is important to remember that the actual efficiency you achieve will be greatly influenced by other factors like the level of insulation, the outside temperature, and your demand for hot water.

Power:

Air source heat pumps are available in a range of different outputs to suit different sizes of homes.

It is important to install the right output, but a professional heat pump installer will be able to advise you on this topic.

Is an air source heat pump the right choice for your home?

While there are numerous advantages and disadvantages to consider when installing an air source heat pump, if you’re drawn to the potential benefits it offers your home, such as:

Reduced Energy Bills: Air source heat pumps are highly efficient heating systems that have the potential to lower your energy bills significantly.

RHI Payments: Air to water heat pumps qualify for quarterly payments over a period of 7 years through the Renewable Heat Incentive scheme.

Environmentally Friendly: Heat pumps require only minimal electricity to operate and generate considerably less carbon emissions compared to fossil fuel heating systems.

Year-Round Heating: Utilize your air source heat pump throughout the year, even during the coldest UK winters.

Low Maintenance: With minimal maintenance required aside from annual servicing, heat pumps can effectively heat your home with little intervention.

Long Lifespan: Many air source heat pumps can last for up to 20-25 years, approximately twice as long as a modern boiler.

It’s important to acknowledge that air source heat pumps may not be suitable for every type of home.

• A high level of insulation
• Outside space for the fan unit
• Large radiators or underfloor heating for maximum heat delivery as heat pumps deliver heat at a lower temperature than boilers
• Small amount of electricity to operate
• A hot water cylinder

To get the best price on an air source heat pump for your home, it is important to compare multiple quotes from different companies. This can take time but we can help make your research a lot easier.

Different Types of Boiler Installations explained:

There are three main types of boiler installation and each has a different level of complexity which can impact the boiler installation times:

1. Straight Swap
2. Boiler Relocation
3. System Upgrade

Please find more details about each type of installation as well as an estimate of the time each type of installation will take:

Type of installation: Straight swap (same location):

Details: A straight swap installation, also known as a like-for-like swap, is a type of boiler installation that involves replacing your current system with a boiler of the same type, in the same place.

Time: This is generally the quickest type of boiler installation as it requires very little change and can often be completed in just one day.

See boiler prices for the costs of your new boiler and boiler installation.

Type of installation: Boiler relocation

Details: A boiler relocation installation requires moving your new boiler to a different location within your property and this could slightly prolong the installation process. Your boiler engineer may have to make changes to the existing pipework or they may have to cap the current pipework and install new elements to the new location. Time: This adjustment could add another day on to the standard one day installation making it up to 2 days of installation*.

*It’s worth noting that the further away you choose to install your new boiler, the longer the installation is likely to take which will also have an impact on your price.

See boiler prices for the costs of your new boiler and boiler installation.

Type of installation- System upgrade:

System upgrade installations are where homeowners choose to change the type of boiler they have installed in the property. For example, switching from a heat only boiler to a combi boiler would be considered a system upgrade. Combi boilers have become the most popular boiler type in the UK, so many people choose to upgrade to this type of system from the older heat only boiler variety.

Time: A system upgrade could make your installation take up to 3 days* or more depending on the complexity of the job.

This may seem like a long process, but the benefits of upgrading to a more efficient system can often make it worthwhile.

Why choosing the right boiler is important?

Choosing a suitable boiler for your home can provide you with all the heating and hot water that your family or property require. You could also save money on your annual energy bills and reduce your carbon footprint by using a more efficient system for your requirements.

MagnaCleanse Vs Power Flush Vs Chemical Flush: Which Is Best and Why?

Welcome to the “MagnaCleanse Vs Power Flush Vs Chemical Flush” section.

Keeping your boiler healthy is important for the continued energy efficiency of your system. Having a regular boiler maintenance service is crucial to a smooth and efficient running of your heating system.

Just like an engine, your boiler and heating system is something that needs to be looked after and regularly maintained in order to keep it running to its peak operating performance.

The best way to do this is by using a full flush process for your central heating system:

System Flushes / Full Flushes:

There are three different types of full heating system flushes:

• PowerFlush
• Chemical Flush
• And the New MagnaCleanse Flush

So the big question is, which type of system flush should you use and why?

Until recently when the newer MagnaCleanse flush arrived, it was very much a powerflush vs chemical flush debate and deciding which was less harmful to your system was one of the main decisions. 

More to think about now!

However now that there is a third option the choice is even more difficult to make.

In this quick inline system flush guide, we will help you to identify the different types of system flush processes available to you.  

We’ll also help you to decide which one is best for you and why!

Why do you need a system flush?

If a system flush isn’t carried out as and when it needs to be, the water in your boiler will eventually be contaminated with rust and other unwanted elements.

Prevents inefficiency over time:

Over time, the rust, debris, and dirt turns into a ‘sludge’ like substance which will prevent your system from functioning as efficiently as it should. Without the right type of flush, your system could become inefficient or even not working.

This would result in the need for a new boiler installation or a boiler repair service to your property to fix the issue.

How regular is a system flush required?

Depending on your current boiler type and brand, you may only need a flush once every 5 years or so. A copper heat exchanger will be much more durable and resistant, as opposed to stainless steel one.

Depending on the boiler type, a flush may be necessary more often again…

If you’re unsure or would like some further advice on when your boiler’s next flush is due, or which flush is best*, please chat with one of our expert engineers by contacting us via the contact details!

*However we will always recommend a MagnaCleanse over any other type of flush.

MagnaCleanse Flush

Approved by our manufacturer partners, a MagnaCleanse is a highly effective way of keeping your system protected. So if the experts say to use it, it’s probably best to use it. 

So, What is a MagnaCleanse Flush?

The MagnaCleanse system flush is the process of clearing your system of those harsh, unwanted materials it has contained within it. It thoroughly cleans your entire heating system.  This provides consistent protection to your pipes and boiler.

Easy Disposal:

The added benefit of a MagnaCleanse filter helps to collect sludgy residue away from your system for easy disposal.

Do i get Free MagnaCleanse Flush with a new boiler install?

We carry out a MagnaCleanse system flush free with every boiler installation or replacement. This will ensure your heating system will stay as new as possible for as long a time period as possible.

What is a power flush?

A central heating power flush is one of the older cleaning processes for a central heating system. As it sounds, this process uses a solution of chemical that travel through your system and pipes. This chemical solution removes debris, dirt, and rust as well as any other unwanted waste material.

What is a chemical flush?

A chemical flush is similar to a power flush but does differs from a power flush.

Why is the chemical flush different?

The chemical flush is different because it uses gravity to empty the system and refill it. During this process, the cleaning chemicals are dispersed around the system to remove unwanted materials and residue. The system is then flushed with clean water and boiler inhibitor to ensure that the system is left fully protected.

How to flush a central heating system:

There are three main ways to flush a central heating system:

1. MagnaCleanse
2. PowerFlush
3. Chemical Flush

How to MagnaCleanse a central heating system?

Firstly, before you MagnaCleanse a system, it’s important to drain it completely. Then, connect the MagnaClease RapidFlush filter to your system valves using the provided hoses.

Quality Cleaning Solution:

The MagnaCleanse cleaning solution can then be added to the system. By combining the flush components with quality cleaning chemicals you’ll have a special formula ready to intensely clean your system at a high strength.

The sludge will be collected in the filter which can be easily disposed of.  

How to power flush a central heating system:

To carry out a power flush, it should always be an engineer’s job. They will connect a pump to your central heating system from either the pump head or the circulation pump (depending on boiler type).  Your engineer will then pump a chemical solution through the system removing any debris and rust, helping to replenishing your boiler. The solution will include a descaling agent as well as other chemicals that will prevent rust from forming.

The waste materials will then be collected and disposed of safely by an engineer.

How long does a power flush take?

A power flush cleaning process can be a lengthy process, but the results will be more than worth the wait.

The power flush process could take from 5 hours to 10 hours, depending on a number of factors like:

•        Number of radiators that you have.
•        How old your current boiler system is.
•        Amount of ‘sludge’ in your pipes/system.

Throughout the process, an engineer will look for other problems.

These include any current or potential new blockages that could occur in the future.

Some boiler components may need replacing or cleaning to ensure it doesn’t run into any further issues so that you don’t need a future boiler repair.

Haven’t had your boiler flushed for some time?

Your boiler isn’t in the best condition?

Then this procedure will require more time in order to complete the process.

How to chemical flush a central heating system?

A chemical flush is a more basic version of the powerflush but can be just as effective. With this process chemicals are flushed through the system using gravity instead of a pump. As the cleaner is flushed around the system from the boiler, any debris will be caught by a magnetic filter.

Proof of improvement:

When the work is complete, an engineer will be able to show how much your system has improved after the flush. This is done by measuring radiator temperature and comparing it to what it was previously.

The engineer will test your boiler and heating system to ensure that everything is working o optimal performance. By doing this they’ll be able to identify the areas in which there is a build-up of ‘sludge’ and if there are any leak risks. They’ll also be able to give you aftercare advice and ways you can get the most out of your heating system.

How to spot the signs that you need a boiler or heating system flush?

Please find the top 10 reasons why your heating system needs a flush!

• Is your boiler breaking down?
• Does your boiler need to be restarted regularly?
• Do your radiators have cold patches while turned on, especially at the bottom?
• Is your tap water discoloured or cloudy?
• Do your radiators take a long while to heat up
• Do your radiators not get warm at all?
• Are your radiators quite noisy?
• Is your boiler sounding quite noisy?
• When bleeding radiators – is the water cloudy
• Or is there is no water at all when you bleed the radiators.

If you answered ‘yes’ to any of these questions, your system may need a flush.

It’s also a good idea to schedule in a system flush if you have a new boiler installed to ensure it’s in top working condition.

The advantages of a professional MagnaCleanse system flush?

Looking after your central heating system is advantageous for so many reasons like:

• From a deep clean of your system and pipes, you’ll ensure your boiler is more energy efficient and much more reliable than it would be without a flush.
• Because the system will be clear of debris, it will run much smoother increasing the lifespan of your heating system.

What the main benefits of a MagnaCleanse flush is the fact that it can be completed within as little as two hour?

Looking after your central heating system is advantageous for so many reasons like:

• A deep clean of your system and pipes means a more reliable and energy efficient boiler.  This will give you the extra confidence that you need.
• With a fully cleaned system, the chance of a breakdown will be very slim.
• Within two hours of application your boiler will be smoother, cleaner, and more reliable. Not to mention your boilers increased lifespan.
• You will also have hotter radiators which heat up more quickly.
• The cost of regularly replacing parts from a poor functioning boiler will be eliminated and you’ll have the peace of mind that you can trust your heating system to deliver to a high standard each day, as you’d expect it to.
• With a fully cleaned system, the chance of a breakdown will be very slim.
• You will have hotter radiators as they heat up quicker – great for those cold winter nights.
• You will no longer have to worry about replacing parts as you’ll have a dependable heating system you can trust.

MagnaCleanse Vs Power Flush Vs Chemical Flush – Cost Differences:

The cost of a flush will entirely depend on a number of factors like:

• The complexity of your system.
• The size of the system.
• Number of Boilers.
• Number of Radiators.
• Type of Flush.

Engineers will also need to consider the possibility of running into a problem, which could hold the job up further. Total flush costs can vary between engineers – ranging from around the £300-£700 mark for any of the flush cleaning processes. There may also be additional costs dependent on additional work required or any part needing replacement for a fully efficient working system.
