At Green Squirrel Energy, underfloor heating isn’t an add-on – it’s our core engineering discipline. We design every system using the latest heat pump science, modern building physics and cutting-edge digital modelling tools, ensuring that every client receives a solution that performs exactly as promised.
Where some installers reuse outdated radiator methods or “rule of thumb” layouts, we engineer from first principles. Every project benefits from:
The Latest Design Knowledge
We apply current heat pump design standards, manufacturer guidance and real-world performance data to create systems that deliver maximum efficiency, superior comfort and long-term reliability.
Precision Modelling Using H2X Engineering & Spruce Software
Our systems are engineered using professional-grade tools such as H2X Engineering and Spruce heat pump design software, enabling room-by-room heat loss analysis, exact pipe layout optimisation, and accurate predictions of flow temperature and running cost.
This ensures your system is:
- Mathematically accurate
- Balanced and efficient
- Designed to heat every room correctly
- Fully optimised for heat pump operation
Floor Covering Expertise for Perfect Real-World Performance
Our design ensures your chosen flooring performs flawlessly with underfloor heating, preventing underheating and protecting delicate materials.
Floor coverings dramatically affect heat output. We account for:
- Tiles
- Engineered wood
- LVT / Vinyl
- Carpet & underlay (true Tog values)
Designed Around How You Actually Live
Every home is different. We tailor your system to:
- Your heat source (Mitsubishi Ecodan, Octopus Cosy, Vaillant, Samsung etc.)
- Zoning requirements for comfort and compliance
- Setback strategy for efficiency
- Room usage patterns
- Fast-response vs thermal storage needs
No guesswork. No generic kits. Only true engineering precision.
Intelligent, Modern Part L Compliance
Part L Building Regulations were written around high-temperature radiator systems – not today’s low-temperature heat pumps and advanced underfloor heating. Green Squirrel Energy ensures full compliance, but we don’t blindly follow outdated examples. Instead, we apply:
- Common sense
- Modern heating engineering
- Real-world understanding of heat pumps
- The latest emitter and zoning best practices
This approach produces systems that are:
- Fully compliant
- Highly efficient
- Perfectly zoned
- Matched to your home’s thermal performance
- Optimised for low running costs
We bridge the gap between regulations and reality.
The Result: A System That’s Simply Better
Every Green Squirrel Energy design is:
- 100% technically accurate
- Optimised specifically for heat pumps
- Perfectly matched to your floor construction and coverings
- Guaranteed to deliver the comfort and savings you expect
- More efficient than traditional radiator-based designs
- Engineered using the industry's most advanced tools
You don’t just get a UFH system. You get a precision-engineered heating solution built for the next 25+ years.
In Summary
Green Squirrel Energy offers more than installation. We deliver industry-leading heating design, built on:
- Advanced software (H2X & Spruce)
- Modern heat pump design principles
- Mastery of underfloor heating physics
- Intelligent interpretation of Building Regulation
- Deep understanding of floor coverings and home usage
This combination makes our systems more efficient, more accurate and more reliable than anything produced using traditional methods.
Green Squirrel Energy doesn’t just meet the standard – we set it.
