What is a Heat Pump?

A heat pump is an energy-efficient, renewable heating system that extracts heat from the air, ground or water outside your home. It uses this heat to warm your radiators, underfloor heating or air systems.

Unlike traditional boilers that burn fuel, heat pumps use electricity to transfer heat, making them up to 300% more efficient than conventional heating systems-saving you money on energy bills and reducing your carbon footprint.

Efficient Heating

For every 1kW of electricity used, heat pumps generate 3-4kW of heat

Eco-Friendly

Significantly reduces carbon emissions compared to gas boilers

Future-Proof

Aligned with UK's 2035 gas boiler phase-out plans

How Heat Pumps Work

  • 1

    Extract - Heat is absorbed from the outside air, ground, or water (depending on the type of heat pump)

  • 2

    Compress - The refrigerant is compressed to increase its temperature, making it suitable for heating your home

  • 3

    Transfer - The heated refrigerant is transferred to your heating system, whether it's radiators or underfloor heating

  • 4

    Circulate - Warm water flows through radiators or underfloor heating systems, warming your home efficiently

Different Types of Heat Pumps

Compare air source, ground source, and hybrid heat pumps to find the best match for your home, needs, and budget.

GSHP

Ground Source Heat Pump

Ground Source Heat Pumps extract heat from the ground through underground pipes. They offer higher efficiency and are ideal for homes with more space, as they require a garden area for installation.

  • Higher efficiency
  • Quieter operation
  • Lower running costs
  • Ideal for larger homes with garden space
Hybrid

Hybrid Heat Pump

Hybrid Heat Pumps combine the efficiency of a heat pump with the reliability of a traditional boiler. Ideal for homes that need consistent heating in all weather, this option provides reliable backup heating while offering optimal energy efficiency.

  • Best of both systems
  • Ideal for older homes
  • Reliable backup heating for all weather
  • Increased energy savings and comfort

Why Homeowners Choose Heat Pumps

Discover why heat pumps are one of the most efficient, eco-friendly, and cost-effective heating solutions for modern homes.

Energy Efficient

Heat pumps use renewable energy from air or ground, delivering up to 4x more heat than the electricity they consume, lowering energy bills significantly.

Lower Heating Costs

By reducing reliance on gas and traditional boilers, heat pumps can cut your annual heating costs while protecting you from rising fuel prices.

Eco-Friendly Heating

Heat pumps produce far fewer carbon emissions, helping reduce your home's environmental impact and support a greener future.

Quiet & Comfortable

Modern heat pumps operate silently and provide consistent, even heat throughout your home without sudden temperature drops.

All-Year Comfort

Heat pumps can provide heating in winter and cooling in summer, making them a versatile, year-round solution.

Long Lifespan & Warranty

Designed to last 20+ years, heat pumps come with strong manufacturer warranties for long-term peace of mind.

Got Questions?

Get answers to the most common questions about heat pumps and installation.

Do heat pumps work in cold weather?
Yes! Modern air source heat pumps work efficiently in temperatures as low as -15°C to -25°C. Ground source heat pumps are even more consistent as underground temperatures remain stable year-round.
How long does a heat pump last?
Heat pumps typically last 20-25 years with proper maintenance - significantly longer than traditional gas boilers which last 10-15 years. Ground source systems can last even longer.
Will I need new radiators?
Not always. Heat pumps work best with larger radiators or underfloor heating as they produce lower temperature heat. Your installer will assess whether upgrades are needed during the survey.
How much can I save on energy bills?
Typical savings are £300-£500 per year compared to a gas boiler, and up to £1,000+ if replacing oil or LPG heating. Savings depend on your home's insulation and electricity tariff.
What is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme (BUS) provides £7,500 grants for air source and ground source heat pumps in England and Wales. Your MCS certified installer applies for the grant on your behalf.
How noisy are heat pumps?
Modern air source heat pumps operate at around 40-50 decibels - similar to a refrigerator or quiet conversation. Ground source heat pumps are virtually silent as the outdoor components are underground.
Do I need planning permission?
Most air source heat pumps fall under permitted development and don't need planning permission. However, listed buildings, conservation areas, and ground source systems may require approval.
