Heating that’s cool
for the planet

With Quantum in your home, you can reduce your carbon emissions.

How? It’s all thanks to the intelligent charging tech inside every heater. When there’s high demand for electricity on the grid, Quantum can pause charging, preventing the need for carbon-heavy gas-powered generators to be switched on.

Did you know that when there is a high demand for electricity on the grid, Quantum can pause charging? This prevents the need for those carbon-heavy, gas-powered generators to be switched on when you want to heat up your home.

By charging your Quantum later on in the day (when the grid is more likely to be powered by renewables) your heaters are a step forward towards fighting global warming whilst also contributing towards the goal of a more flexible grid.
