Renewable Heating Solutions

Heat Pumps & Low-Carbon Heating

Efficient heating and hot water from air-source and ground-source heat pumps. Cut gas reliance, reduce carbon emissions by up to 75%, and future-proof your home's heating system.

What are Heat Pumps?

Heat pumps work like refrigerators in reverse – they extract heat from the air or ground outside and concentrate it to provide space heating and hot water for your home. For every 1kW of electricity consumed, a heat pump can deliver 3–4kW of heat, making them far more efficient than traditional boilers.

With the UK phasing out gas boilers from 2025 and offering grants for heat pump installation, now is the ideal time to upgrade to this proven, efficient heating technology.

Types of Heat Pumps

Air-to-Air

💨 Air-to-Air Heat Pumps

Extract heat from outdoor air and distribute it directly via indoor fan units. Ideal for homes without radiators or underfloor heating. Can also provide cooling in summer.

Heating & coolingQuick installationNo radiators needed
Air-to-Water

💧 Air-to-Water Heat Pumps

Extract heat from outdoor air and transfer it to your home's water-based heating system (radiators or underfloor heating). Most popular retrofit option for UK homes.

Ground Source (GSHP)

🌍 Ground-Source Heat Pumps

Extract stable heat from the ground via buried pipes or boreholes. Higher efficiency and lower running costs, ideal for properties with garden space and long-term planning.

Key Features

⚡ 300–400% Efficiency

Coefficient of Performance (CoP) of 3–4 means you get 3–4kW of heat for every 1kW of electricity, far exceeding gas boilers at ~90% efficiency.

♻️ Low Carbon Heating

Reduce carbon emissions by 50–75% compared to gas heating, increasing as the UK grid decarbonises. Fully compatible with renewable electricity.

🌡️ Year-Round Operation

Modern heat pumps operate effectively down to -20°C, providing consistent heating throughout UK winters and reversible cooling in summer.

💧 Hot Water Integration

Provide both space heating and domestic hot water (DHW) from a single system, replacing boilers and reducing maintenance complexity.

🔇 Quiet Operation

Modern units run at <45dB, quieter than typical HVAC systems, with acoustic enclosures available for noise-sensitive locations.

📊 Smart Controls

Intelligent weather compensation, zone control, and remote monitoring optimise performance and integrate with building management systems.

Ideal Applications

� Detached Homes

Replace aging gas or oil boilers with efficient heat pumps, cutting energy costs and future-proofing your heating system.

🏘️ New Builds

Modern well-insulated new homes are perfect for heat pumps, with underfloor heating providing optimal efficiency and comfort.

♻️ Renovation Projects

Combine heat pump installation with home insulation upgrades for maximum efficiency and long-term energy savings.

Pros & Cons

✅ Advantages

  • Exceptional efficiency: 300–400% efficient vs 90% for gas boilers.
  • Carbon reduction: Cut heating emissions by 50–75% immediately.
  • Lower running costs: Cheaper to run than oil or LPG, competitive with gas.
  • Future-proof: Aligned with UK net-zero targets and gas boiler phase-out.
  • Renewable-ready: Pair with solar PV for near-zero-carbon heating.
  • Dual purpose: Provides heating in winter and cooling in summer (reversible units).
  • Low maintenance: Fewer moving parts than combustion boilers, longer lifespan (20+ years).
  • Grants available: Eligible for government incentives like the Boiler Upgrade Scheme.

⚠️ Considerations

  • Higher upfront cost: £8k–£18k depending on system size (£5k–£7.5k BUS grant available).
  • Lower flow temperatures: Work best with underfloor heating or oversized radiators.
  • Space requirements: Outdoor units need adequate clearance; ground-source needs land/boreholes.
  • Building fabric: Best performance in well-insulated buildings; retrofits may need upgrades.
  • Electricity dependency: Running costs linked to electricity prices (mitigated by solar).
  • Installation complexity: Requires skilled installers and careful system design.
