Ovo Partners With Glen Dimplex To Deliver Smart Heating

The title of this post is the same as that of this article on Utility Week.

If you read the article, you will find out how the humble electric storage heater could be joining the smart electricity grid.

This is a paragraph.

It says the facility to store excess energy can lower the cost of electrification by reducing the need for backup generation and investment in the power grid to increase its peak capacity. Analysis by Imperial College London has indicated that deploying smart flexible heating could cut decarbonisation costs by £3.9 billion per year.

This is going to be technology to watch.

Especially, if your heating needs are best met by some form of electric storage heaters.

  1. Storage of energy in heat form is an excellent way to hold energy that is going to end up heating water or living spaces. Heat stores using water are now quite common and avoid the need to store water that is going to be used by the consumer. A highly insulated tank contains water that is heated by a immersion element powered by PVs and/or cheap rate electricity, or by solar thermal panels on the roof via a heat exchanger. They provide heat to water for taps and showers via another heat exchanger fed directly from the water mains. A third heat exchanger can also provide water for heating. This is a very simple scheme and requires no expansion tanks, pressure relief valves or tundish. Also this scheme eliminates the risk of legionella, as no potable water is stored. A more interesting heat store is the phase change unit. This uses a medium that changes state from a solid to a liquid when heated, so it utilises the latent heat of the medium during phase change to hold more heat than its simple thermal capacity. This significantly reduces the size of the heat store, and requires no stored water. Being much smaller, this type of heat store can also be located close to the point of use giving rapid hot water at the point of use, and avoid cold water runoff and unwanted heat loss from pipework during delivery and afterwards.
    Heat stores can also feed an underfloor heating system, avoiding the unnecessary heating of ceilings before floors from convection heaters such as radiators (that don’t radiate), and electrical storage heaters.

    • It’s all good stuff! The only problem with storing heat, is that it is difficult to sell it back as electricity!
