Take these questions to the installer.
For 3–4 people, using electric storage.
- Have the installer assess outdoor space before including a heat pump in the shortlist.
- Compare electric storage and heat pump options using the full installation scope.
- Ask which heating schedule and electricity tariff assumptions the quote uses.
- Explain your busiest hot-water period so capacity and recovery can be checked.
- Ask for the proposed model, installation work and any incentive to be itemised separately.
Why this isn’t a litre calculator
Household size alone can’t establish the right tank or continuous-flow capacity. Peak demand, recovery rate, temperature rise, heating times and the specific model all need to be considered by the installer.
This tool captures the questions behind that decision. It doesn’t produce a technical design, energy-saving promise or incentive estimate. Ask the provider to explain the model recommendation in the context of your actual property.
