What is Economy 7 Heating
Economy 7 heating is where electric night storage heaters are charged up every night with electric heat and then this heat is then released the next day very slowly.
Night Storage Heaters store thermal energy by heating up internal ceramic bricks (effectively, ‘charging’ like a very large rechargeable battery) during the night when electric is at its cheapest.
Storage heaters are primarily designed for customers to benefit from off peak energy which is used to charge up these heaters on a nightly basis.
Storage heaters are usually the best option for households not connected to the gas grid and need to use electricity as a heat source. You will need an economy 7 meter for best use of them
What Is Off Peak Energy & What Off Peak Tariffs Are Available ?
Many energy suppliers offer significant discounts on the use of electricity at night time as demand for power is significantly reduced.
This is called the ‘off-peak’ period and the companies reduce the cost of power between midnight and 7am.
The “Economy 7” tariff is the most well-known. Economy 10 is another one.
You get one meter which has two rates.
You pay normal prices during the day, but cheaper rates for seven hours during the night (usually 12pm-7am).

What Is An Economy 7 Meter ?
Economy 7 meters, are separate meters which have to be specially installed that track day and night use of electricity separately.Tjhis is the preffered method for night storage heaters.
Different kWh rate can be offered via an Economy 7 tariff – a bit like peak and off-peak phone calls. Night time electric is much cheaper and this is when your storage heaters should be charged up
This can be a good way of saving money for energy customers.
How does Economy 7 work?
Economy 7 allows you to get cheaper electricity for seven hours each night.
These tariffs use a different kind of electricity meter which, unlike a standard meter, can track the electricity you use during the day and at night separately.
You’re then charged those different rates for the electricity you use during the day and during the night. The day rate is omore expensive than day rates on a normal tariff, meaning that this doesn’t necessarily fit in with everyone’s lifestyle.
However, it could work for you if you tend to use more energy during the specified Economy 7 times.
