Energy Calculators
Explore energy use, running costs and capacity with stated assumptions. These planning tools do not replace a site assessment or detailed design.
Explore energy use, running costs and capacity with stated assumptions. These planning tools do not replace a site assessment or detailed design.
Compare running costs across boiler types and heat-pump SCOP, then explore a whole-building heat-loss screening estimate.
Open calculatorExplore roof orientation, shade and solar yield. For daily grid shifting and outage demand, use the battery capacity planner.
Open calculatorCompare daily cheap-rate grid shifting with 1–14 days of outage demand, including heating and storage losses.
Open plannerCompare cash with a loan using the deposit, fees and repayments, with an optional savings-return adjustment.
Open calculatorEstimate participating water volume from minimum heat-pump output, active heating load and runtime.
Open calculatorUnderstand what goes into an energy payback estimate.
