What is an Air Source Heat Pump (ASHP)?

 

An air source heat pump (ASHP) is a heating and cooling system that transfers heat between the inside of a building and the outside air. It works by extracting heat from the outside air, even in cold temperatures, and using it to heat a home or provide hot water. In warmer months, the process can be reversed to provide cooling by removing heat from indoors and releasing it outside.

How It Works:

 

1. Heat Absorption: The pump extracts heat from the outside air using a refrigerant.
2. Compression: The refrigerant is compressed, increasing its temperature.
3. Heat Transfer: The heated refrigerant transfers warmth to the home’s heating system (radiators, underfloor heating, or hot water tank).
4. Cooling (Reversible Function): In summer, it works in reverse, acting like an air conditioner.

Benefits of an Air Source Heat Pump:

 

• Energy Efficient:Uses less electricity compared to traditional heating systems.
• Eco-Friendly: Reduces carbon footprint by using renewable energy.
• Lower Running Costs: Can be cheaper than gas or oil heating in the long run.
• Dual Functionality: Provides both heating and cooling.
• Government Incentives: Under the MCS Boiler Upgrade Scheme there are financial incentives for installing heat pumps.

ASHPs are commonly used in residential and commercial buildings and are a popular alternative to gas and oil boilers. They work best in well-insulated homes to maximize efficiency.

What is a Ground Source Heat Pump (GSHP)?

 

 

A Ground Source Heat Pump (GSHP) is a highly efficient heating and cooling system that extracts heat from the ground to warm your home and provide hot water. In summer, it can reverse the process to provide cooling.

How It Works:

 

1. Heat Absorption: A network of pipes, called a ground loop, is buried underground. A mixture of water and antifreeze circulates through these pipes, absorbing heat from the ground.
2. Compression: The heat is transferred to a refrigerant, which is compressed to increase its temperature.
3. Heat Distribution: The heat is used to warm your home through radiators, underfloor heating, or a hot water system.
4. Cooling Mode (Optional): In warm weather, the system can work in reverse, removing heat from your home and storing it in the ground.

Types of Ground Source Heat Pumps:

 

• Closed-Loop System: Most common; pipes are buried in horizontal trenches or vertical boreholes.
• Open-Loop System: Uses groundwater from a well or lake to extract heat.

Benefits of a Ground Source Heat Pump:

 

• Extremely Energy Efficient – Can use 3-4 times less electricity than traditional heating
• Low Running Costs – Can significantly reduce heating bills
• Environmentally Friendly – Uses renewable energy, reducing carbon emissions
• Long Lifespan – Systems can last 20-25 years, with ground loops lasting over 50 years
• Works Year-Round – The ground maintains a stable temperature, ensuring reliable performance.

GSHPs are commonly used in residential and commercial buildings and are a popular alternative to gas and oil boilers. They work best in well-insulated homes to maximize efficiency.

What is the Boiler Upgrade Scheme (BUS)?

 

The Boiler Upgrade Scheme (BUS) is a UK government initiative designed to encourage homeowners and businesses in England and Wales to switch from fossil fuel heating systems (like gas or oil boilers) to low-carbon heating technologies, such as air source heat pumps (ASHPs), ground source heat pumps (GSHPs), and biomass boilers (in some cases).

How Does the BUS Work?

 

• Provides upfront grants to help cover the cost of installing heat pumps.
• Reduces the financial barrier for switching to eco-friendly heating.
• Encourages carbon reduction in homes and businesses.

Grant Amounts (as of 2024):

 

• £7,500 for air source heat pumps (ASHPs)
• £7,500 for ground source heat pumps (GSHPs)

Eligibility Criteria:

 

1. Property Location: Must be in England or Wales.
2. Replacing a Fossil Fuel System: Must replace an oil, gas, LPG, or direct electric system (not an existing heat pump).
3. Energy Performance Certificate (EPC): The home needs a valid EPC without outstanding insulation recommendations.
4. Grant Application: The installer applies on behalf of the homeowner.

How to Apply?

 

1. Find an MCS-certified installer who is registered with the scheme.
2. The installer applies for the grant on your behalf.
3. The grant is deducted from the upfront cost of installation.
4. The grant is subject to meeting all the criteria and approval.

Why Consider the BUS?

 

• Huge Savings: Makes heat pumps much more affordable.
• Lower Energy Bills: Heat pumps are more efficient than fossil fuel boilers.
• Future-Proof Your Home: Government plans suggest a long-term phase-out of gas boilers.
