how do,es economy7 work

its cheaper to heat ur water or use ur washing machine from the hours of 7pm til 1am

l have economy 7 at home. They charge a lower rate for electricity used after a certain time. My storage heaters are set on economy 7 as is my emmersion so they heat up over night an costs me less.

There is less damand on electricity at night so it can be sold at a lower price than during the day. Economy 7 utilises this by storing energy at night and giving it out during the day.

For 7 hours at night u get cheaper electricity because this is the time that there is least demand. Its best to do washing or cleaning at this time!!!
