HeatNet Designer brings the whole heat-network workflow into one tool, so engineers spend less time juggling spreadsheets and separate applications. Take a scheme from buildings on a map through to a compliance-checked, reportable design, with figures and diagrams ready to drop into internal reviews and client presentations.
For local authorities, energy consultants and developers designing UK district heating.
Figures from the built-in Stratford DH worked example.
Every result is computed from the network you draw and checked against the standards UK heat networks are assessed against, so the design, the cost and the compliance stay consistent.
Pipe sizing, pressure drop and heat loss computed from first principles to CIBSE CP1, BS EN 253 and EN 13941.
Design on a real Ordnance Survey or OpenStreetMap basemap, auto-route the network along the streets, and take trench lengths from real geometry instead of measuring by hand.
An 8,760-hour, full-year energy balance with thermal storage and part-load behaviour, plus one-click optimisation of the source mix for lowest cost or carbon.
Operational carbon over the UK grid decarbonisation trajectory, plus embodied carbon of pipework and plant from cited literature and the EN 253 build-up.
CIBSE CP1, draft TS1:2025 and HNTAS checks computed from the live model as you design, evaluating the relevant value for each requirement.
EPC and TM46 demand lookups, PVGIS weather data, and UK grant and tariff modelling, built in.
Conventional flow / return district heating.
Modern low-loss distribution design.
Ambient shared loops with local heat pumps.
Hydraulics, analysis and standards checks computed against a single model and reused across every scheme.
CAPEX, OPEX and REPEX, payback, tariff and grant modelling with tornado sensitivity, all derived from the same design.
Automated compliance checks and EPC / TM46 demand estimates for the buildings where metered data isn't available.
Open the designer and take a scheme from buildings on a map to a standards-checked design in one workspace, or take the full product tour first.
