What is Off-Peak Storage Heating?
Use your cheap times to heat your home. Just like a battery, off-peak storage heating banks the cheapest, cleanest electricity overnight for you to use the next day.
Which as a result saves money and cuts carbon emissions.

How is it different?
Most heating systems work in real time – as soon as you switch on, it’ll burn through its power supply there and then.
When we all switch on electric heating at the same time, we create a ‘peak’ in energy demand, and during winter this needs to be satisfied using fossil-fuels at the Vale power station, which cost millions of pounds to replace.
Off-peak heating stores energy overnight for you to use the next day. That’s a heating system and a battery, all in one.
As less people use electricity overnight, this is when we can rely on 100% low-carbon electricity imported from the European grid via a subsea cable.
So why not heat with sunshine, wind and water instead.
What’s the catch?
Off-Peak storage heating can be expensive to install.
But for some, expensive once beats expensive forever. So if you'd like to go electric, heat cleaner and cheaper, why not ask your installer about off-peak storage heating.
