At Southern Carpentry Group (SCG), we take pride in delivering complete, high-quality installations that blend technical precision with visual craftsmanship, and this recent heating system installation is a perfect example of that.
Collaboration sits at the heart of every great project.
For this award-winning heating installation, Nu-Heat Underfloor Heating & Renewables provided the technical design and supply; MPK Plumbing & Gas Services Limited executed the installation to an incredible standard; and Southern Carpentry Group managed and coordinated every stage of the build, ensuring that all elements, from structure to system, came together seamlessly.
Itâs a project that reflects the power of partnership, where each specialist brings their best to achieve one outstanding result. designed NIBE air source heat pump system, integrating both heating and domestic hot water functionality with an electric backup.
The installation was designed to maximise efficiency, reliability, and serviceability, and the finished result went on to win recognition from Nu-Heat for excellence in design ex*****on and overall presentation.
System Design & Components
The system follows Nu-Heatâs C21 configuration, featuring:
A NIBE F2040 air source heat pump, providing primary heating and domestic hot water.
A 100-litre buffer tank and a high-performance EnergyPro HP unvented cylinder.
A combination of underfloor heating manifolds and a radiator circuit, each independently controlled via smart zoning.
Full weather-compensated controls through the NIBE SMO20 controller, optimising efficiency across varying ambient conditions.
Correctly installed flow and return temperature sensors, outdoor temperature sensors, and electrical controls, as detailed in the Nu-Heat docking schematics.
All pipework and wiring followed the manufacturerâs guidance for Part G3 discharge safety, Part L insulation standards, and MCS-020 compliance, ensuring the system can be fully certified under renewable energy standards
Installation Details
Our SCG team handled every stage of the install internally, from first fix to commissioning. Key details include:
All primary and secondary pipework installed in 28mm copper, fully insulated with Armaflex Class 0 laggingto prevent heat loss and condensation.
Flow balancing and hydraulic separation achieved through the Nu-Heat buffer and dedicated circulators for underfloor and radiator circuits.
MagnaClean HP filtration integrated for system protection and long-term efficiency.
Full electrical integration carried out to Nu-Heatâs schematic standard, including individual fused spurs, DIN-rail mounted meters, and isolators for each component.
Optional secondary domestic hot water loop capability pre-piped for future expansion.
Finishing Touches
· Beyond the technical build, the plant room was finished with Altro Whiterock hygienic wall cladding, giving a clean, clinical aesthetic while ensuring compliance with hygiene and durability standards.
· Lighting was designed to highlight the precision of the installation, with geometric LED panels enhancing visibility and presentation for maintenance and client handover.
· The result is not only a high-performance heating and hot water system but a visually striking installation that represents the SCG standard, neat, organised, and engineered for longevity.
Recognition
· Weâre proud that this installation received award recognition from Nu-Heat, who designed and supplied the system, for the exceptional standard of delivery and presentation.
· This project demonstrates whatâs possible when detailed design, skilled workmanship, and pride in presentation come together
