Tool index
Calculator · ventilation / heat loss
Ventilation heat loss
Estimate extra heat needed when extract fans, open doors or air changes are dragging warm air out of a workspace.
For warehouses, workshops, drying rooms and spaces with high air movement.
Calculator · destratification / warehouse
Destratification savings
Estimate whether destratification fans could reduce heat stacking and improve heater effectiveness in high spaces.
For warehouses, workshops, gyms and industrial units.
Calculator · connector / commando plug
Heater supply selector
Pick the likely connection class for an electric heater: 13A plug, 16A, 32A, 63A or three-phase.
Useful where heater kW is known but the supply type is not obvious.
Calculator · three-phase / phase balance
Three-phase load balancer
Allocate single-phase heaters, dehumidifiers, fans and portable AC units across L1/L2/L3 to reduce imbalance and nuisance trips.
For 32A, 63A and 125A temporary distribution boards with mixed 230V loads.
