Air source heat pump grants are low-carbon technologies that provide effective heating and cooling alternatives for houses in any climate. They are an excellent solution for your home as they can transport heat from the outside without creating it by burning fossil fuels.

Compared to conventional heating technologies, ASHPs installation will immediately result in lower utility bills and increased energy efficiency. 

To save annual heating costs by £340 compared to an outdated G-rated gas boiler, the UK government has launched free air source heat pump grants under the ECO4 Scheme.

The program’s goal is to assist and motivate UK households to be able to pay for the upfront installation of low-carbon heating systems, like air source heat pumps. People who meet the eligibility requirements can get grants of up to £7,500 for air-source heat pumps under this scheme.

When it comes to keeping your house warm, reducing heating expenses, and protecting the environment by decreasing carbon emissions, ECO4 air-source heat pumps are a great option. 

How does the air source heat pump grant work?

How does the air source heat pump grant work?

In order to heat your home air source heat pumps convert heat from the outside air into water. Air source heat pumps use refrigerant fluid to collect heat from the ambient air. After that, a heat exchanger compresses the heat and sends it to your heating system. The procedure is reversed to produce cooling in cooling mode. These pumps are ideal for cold climates because of their excellent efficiency and ability to remove heat even at below-freezing temperatures.

Air-source heat pumps grants are a good option for homes in colder climates as they efficiently capture heat from the surrounding air.

Types of Air Source Heat Pump Grant: 

Air source heat pumps come in two different types. Their primary difference is their heat distribution process through water or air.

Air-to-air heat pumps

An air-to-air heat pump transports heat from the outside air straight into your home, usually using a ventilation fan system. 

An air-to-air heat pump might break even in 6–12 years at an average cost of £1,500–8,000. An annual budget of £650–£800 will cover the operational expenditures of a household with two to four members.

Air source heat pumps may transition from heating to cooling depending on the season, functioning as an air conditioner in the day’s heat and a heating source in the winter. They also consume a lot less energy than a standard system. This kind of heat pump is among the least expensive on the market and is efficient and sustainable.

Air-to-water heat pumps

Air-to-water heat pumps transport heat from the outside air to a wet central heating system, usually via radiators or underfloor heating. They can generate enough heat to meet home hot water requirements and central heating.

An air-to-water heat pump usually runs between £7,000 and £18,000, with operating costs for a three-bedroom home estimated to be between £750 and £950. Air-to-water heat pumps often pay for themselves in eight to twelve years.

The service life of air-to-water heat pumps varies from 10 to 15 years, depending on the model, location, and maintenance. 

Air-to-water pumps provide hot water at low temperatures and underfloor heating, central heating, and hot water without needing an additional system. The decision between air-to-air and air-to-water heat bumps comes from personal preference and the building’s heating and cooling needs.

Air-Source Heat Pump Efficiency

Let’s Know About the Benefits of Air Source Heat Pump Grant:

Air source heat pumps have several advantages, including lower energy costs, less carbon footprint, and more home comfort. The top features that will continue to make this system appealing are outlined below…

Save Money

Saving hundreds of pounds annually on energy expenses is one of the main benefits of air-source heat pumps for houses. Homes could potentially save up to £1,500 on expenses annually by using air-source heat pumps, which are far more energy efficient than more conventional heating and cooling systems like air conditioners or boilers. Furthermore, this is the best time to invest because green energy solutions are VAT-free! We’ll explore the exact sum of money you could save by upgrading to an air-source heat pump later in this post.

Reduce Carbon Footprint:

Compared to conventional heating and cooling systems, air source heat pump grants generate substantially fewer emissions and are a low-carbon heating technology. They can assist in lowering your carbon footprint and improve your house’s sustainability because they emit fewer emissions. An air source heat pump requires one unit of electricity for every three to four units of energy produced, making it an excellent option for families looking to reduce emissions.

Ability to be used as a Cooling or Heating Source:

The power of an air source heat pump to heat and cool a building is one of its main benefits. As you can use the same device to transition between heating and cooling at different times of the year, they are incredibly versatile. Furthermore, hot water up to 60 Celsius can be produced throughout the year with air-source heat pumps. Further increasing their efficiency, underfloor heating is a common application for these heat pumps.

Effective throughout the year:

A particular benefit of air source heat pumps is their seasonal coefficient of performance (SCOP), making them exceptionally efficient. Because of their unique design, these devices can supply up to four times as much energy as they need to operate. The standard UK home uses more than 12,000 kWh of heating each year. An air source heat pump might produce the same energy using merely 4,000 kWh of electricity. This makes them an excellent option for heating and cooling your house every season!

Prolong Lifespan:

The long lifespan of air-source heat pumps is one of their key benefits. In fact, with the right care, air-source heat pumps can last up to 20 years. Further, they typically have a five-year warranty included. They are an excellent long-term investment because you can profit from them without worrying about replacing them too frequently.

Easy Maintenance:

Moreover, it’s important to note that air-source heat pumps require very little maintenance while discussing them. Because air source heat pumps don’t require fuel, such as gas or oil, they can be installed without a tank, compared to conventional heating and cooling systems. Additionally, their components rarely need to be replaced because they have few moving parts and a long lifespan.

Good for Space Heating and Hot Water:

Air source heat pump grants are an excellent all-in-one solution for your house as they can be used for both space heating and hot water, thus increasing their range of uses.

Simple Installation

The fact that air source heat pumps are so easy to install is another fantastic advantage. As all you need is some plumbing and an exterior wall or flat roof, installing a boiler is comparable to installing a regular boiler. Additionally, as all of the equipment usually resides inside your home, the installation procedure can typically be completed with the slightest disturbance. You may also get your system up and running quickly with an easy-to-install and manage solution!

Less Noisy than Traditional Heating Systems and Boilers:

The low noise level of air source heat pumps is the final advantage on our list. They make almost less noise when operating, unlike traditional boilers and heating systems. Therefore, they are highly beneficial to people who wish to live in peaceful neighbourhoods or densely populated places. Furthermore, unlike conventional boilers, air-source heat pumps don’t need big ventilation holes, making installation easy and quick. While they are not entirely silent, their noise level is far lower than that of an outdated heating system or boiler

Maintenance and Care for Outstanding Performance:

Maintaining and taking care of the system properly will guarantee that it is working to its maximum capacity. It’s advised to have a professional evaluate your heat pump once a year to make sure the air filters are clean, perform small repairs, and offer suggestions for upgrades.

For the outside unit to last longer, it must also be maintained clear of dirt. Ensure that:

  1. To ensure that the system uses clean water and prevents damage, the filter in the external component needs to be cleaned regularly.
  2. To guarantee appropriate air intake and outflow, the unit needs to be kept dry and the surrounding area clean.
  3. Depending on the quality of the local water, cleaning the tank in the event of scale development is recommended. Additionally, leaks in the system should be routinely monitored.
