Air Source Heat Pumps

At 5 Star Heating & Renewable Energy Limited, we're Cornwall's renewable energy specialists, providing professional air source heat pump installation and servicing. With over 25 years of heating experience, we help homeowners across Cornwall transition to efficient, sustainable heating solutions.

‍

What Are Air Source Heat Pumps?

Air source heat pumps (ASHPs) are innovative renewable heating systems that extract heat from the outside air and transfer it into your home for heating and hot water. Even when outdoor temperatures are as low as -15°C, modern heat pumps can still extract useful heat energy.

These systems work like a refrigerator in reverse – using a refrigeration cycle to absorb heat from the outside air and concentrate it for use inside your home. They're one of the most efficient renewable heating technologies available today.

Benefits of Air Source Heat Pumps

Exceptional Efficiency
Modern air source heat pumps achieve efficiencies of 300-400%, meaning for every unit of electricity used, they produce 3-4 units of heat energy.

Renewable Energy
Heat pumps use renewable energy from the air, significantly reducing your carbon footprint compared to fossil fuel heating systems.

Lower Running Costs
Despite higher electricity prices, the exceptional efficiency often results in lower annual heating costs compared to oil, LPG, or electric heating.

Government Support
The Boiler Upgrade Scheme provides grants of up to £7,500 towards air source heat pump installation, making the transition more affordable.

Heating and Cooling
Many air source heat pumps can provide both heating in winter and cooling in summer, offering year-round comfort control.

Low Maintenance
With fewer moving parts than traditional boilers, heat pumps require less maintenance and have longer service intervals.

‍

Types of Air Source Heat Pumps

Air-to-Water Heat Pumps
The most common type for UK homes, these systems heat water that circulates through your existing radiator system or underfloor heating.

Air-to-Air Heat Pumps
These systems provide warm air directly into rooms and are ideal for single-room heating or as supplementary heating in larger properties.

Hybrid Heat Pump Systems
Combining heat pumps with existing boilers, hybrid systems use the most efficient fuel source depending on outdoor temperature and energy prices.

High Temperature Heat Pumps
Advanced units capable of producing higher water temperatures, suitable for existing radiator systems without requiring radiator upgrades.

‍

‍

Is Your Home Suitable?

Air source heat pumps work best in:

Well-Insulated Properties
Good insulation reduces heating demand, allowing heat pumps to operate more efficiently and cost-effectively.

Properties with Space for Outdoor Unit
The outdoor unit needs adequate space with good airflow and reasonable noise consideration for neighbours.

Existing Wet Heating Systems
Properties with radiators or underfloor heating are ideal, though electric heating can often be converted.

Properties Off Mains Gas
Heat pumps are particularly cost-effective replacements for oil, LPG, or electric heating systems.

‍

Government Grants Available

Boiler Upgrade Scheme
Grants of up to £7,500 are available for air source heat pump installation, significantly reducing upfront costs.

Energy Company Obligation (ECO4)
Additional support may be available for eligible households through the ECO4 scheme.

Local Authority Grants
Some Cornwall councils offer additional renewable energy grants – we can help you identify available support.

‍

Heat Pump Servicing

Annual servicing ensures optimal performance and maintains warranty validity:

• Refrigerant pressure and leak testing
• Electrical connection inspection and testing
• Heat exchanger cleaning and inspection
• Controls calibration and testing
• Performance efficiency assessment
• Filter cleaning and replacement
• Defrost cycle testing
• System pressure checks
• Safety device testing

‍

Common Heat Pump Issues We Resolve

Poor Heating Performance
Often caused by incorrect sizing, poor installation, or system imbalances. We diagnose and optimise system performance.

High Electricity Bills
Usually indicates inefficient operation or incorrect settings. Our expertise can significantly improve system efficiency.

Frequent Defrost Cycles
Normal in cold weather, but excessive defrosting may indicate airflow problems or refrigerant issues we can resolve.

Noise Problems
We can resolve noise issues through repositioning, vibration dampening, or component replacement where necessary.

System Not Starting
Electrical faults or control problems that our experienced engineers can quickly diagnose and repair.
