Sizing
Heat-loss Calculations & Sizing for Specification
How to size a heat pump correctly at design stage, and why oversizing costs performance and money.
The KronoHP difference
Specify heat pumps with confidence
Low-carbon heating is now central to Part L, the Future Homes Standard and BREEAM. Getting the specification right early - the right system, correctly sized and integrated - is what keeps a project on programme and compliant.
This is our library of specifier-focused advice: clear, practical articles written for the people who design and specify, backed by full technical data and dedicated support from our team.

At a glance
Key considerations when specifying
Specify Early
Involving heating strategy at concept stage avoids costly redesign and keeps the project compliant.
Size on Heat Loss
Accurate heat-loss calculations, not rules of thumb, deliver efficiency and low running costs.
Design for Acoustics
At 16 dB, unit placement can meet the strictest siting and planning noise limits.
Check Compliance
Align the specification with Part L, the Future Homes Standard and BREEAM from the outset.
Use NBS-ready Text
Drop our clauses straight into your specification to save time and reduce ambiguity.
Model with BIM
Accurate BIM objects and CAD details keep coordination clean across the design team.
