LOW-CARBON HEATING SOLUTIONS

Renewable Heating Systems

DESIGNED FOR REAL HOMES

Low-Carbon Heating for Housing Providers

Heating remains one of the largest contributors to energy use and carbon emissions in residential buildings. For housing providers and local authorities, transitioning away from fossil fuel heating is essential to meeting decarbonisation targets, improving EPC performance and protecting residents from long-term energy cost volatility. Renewable heating technologies, when specified and installed correctly, provide a proven route to lower-carbon, more efficient heating. WarmPro delivers renewable heating systems carefully matched to the building, the resident and the wider retrofit strategy, ensuring systems perform as intended in day-to-day use.

RENEWABLE HEATING

Air Source Heat Pumps (ASHPs)

Air Source Heat Pumps are one of the most widely deployed low-carbon heating technologies in the UK. They work by extracting heat from outside air and upgrading it to provide space heating and hot water.

When correctly designed and installed, ASHPs:

Deliver high efficiency, typically producing three or more units of heat for every unit of electricity used
Significantly reduce carbon emissions compared to gas, oil or electric resistance heating
Provide consistent, low-temperature heat well suited to insulated homes
Support long-term energy affordability when paired with fabric improvements and smart controls

WarmPro supports delivery of ASHP systems across a range of property types, from individual dwellings to larger programmes, ensuring systems are properly sized, correctly integrated, and set up for real-world occupancy, not theoretical performance.

ALTERNATIVE HEATING TECHNOLOGIES

Ground Source Heat Pumps (GSHPs)

Ground Source Heat Pumps operate on similar principles to ASHPs but extract heat from the ground via buried pipework. While more capital-intensive, they offer very high efficiencies and long system lifespans, making them suitable for certain housing typologies and communal applications.

GSHP systems are typically considered where:

There is sufficient external space or shared ground infrastructure
Long-term performance and lifecycle efficiency are priorities
Whole-block or estate-wide solutions are being explored

WarmPro supports feasibility, design coordination and integration of GSHP systems as part of broader retrofit and decarbonisation programmes.

PRACTICAL TRANSITION PATHWAYS

Hybrid Heating Systems

In some settings, a hybrid approach combining renewable heating with retained or supplementary systems can provide a practical transition pathway. These solutions are particularly relevant where fabric upgrades are phased or where immediate full electrification is not yet viable.

Hybrid systems are assessed on a case-by-case basis, with focus on:

Reducing overall carbon intensity
Maintaining resident comfort and reliability
Supporting future transition to fully renewable heating

WHOLE-HOUSE APPROACH

Integrated, Fabric-First Delivery

Renewable heating does not work in isolation. Heat pumps perform best when heat demand is reduced first through insulation and airtightness improvements.

WarmPro delivers renewable heating as part of a fabric-first, PAS-aligned retrofit approach, ensuring:

Heat pumps are correctly sized to the improved building fabric
Oversizing and inefficiency are avoided
Running costs are minimised
Long-term performance is protected

This joined-up approach reduces risk for housing providers and improves outcomes for residents.

PERFORMANCE IN PRACTICE

Controls, Commissioning and Optimisation

Controls play a critical role in how renewable heating systems perform. Poorly configured systems can lead to resident dissatisfaction and higher-than-expected running costs.

WarmPro places strong emphasis on:

Correct commissioning and balancing
Intuitive controls that residents can understand and use
Settings aligned to building heat demand and occupancy patterns
Clear handover information and support

This ensures systems operate efficiently and residents feel confident using them.

OCCUPIED HOMES, REAL RESIDENTS

Why WarmPro

WarmPro delivers renewable heating as part of a coordinated retrofit strategy, not a standalone technology install. Our strength lies in understanding how heating systems interact with fabric, ventilation, controls and resident behaviour, and designing delivery accordingly.
