Home & energy
Make energy costs and electrification choices easier to understand. Every live tool includes a reviewed method, example and limitations.
Heat pump cost Estimate heat-pump electricity use and compare running cost with gas, oil or another fuel. EV charging cost Calculate energy drawn from the grid and the cost of charging an electric car between two charge levels. Electricity cost Calculate the daily and annual electricity use and running cost of an appliance, machine or group of devices. Battery payback Estimate annual bill savings and simple payback for a home battery using your usable capacity, cycling, tariffs and efficiency. Radiator output Estimate a radiator’s output at heat-pump flow and return temperatures, then compare it with a room heat-loss requirement. Solar after saldering Estimate how ending the Dutch salderingsregeling changes the annual value of your solar electricity using your own consumption and contract rates.
