Smart Cylinder

[hard-work]

A new cylinder that heats top down with a smart computer control. You decide how much of the cylinder you want heated. Also with a Smart app. Nation Grid are using them to dump surplus electricity into when they produce too much, or to balance the grid. It appears they are using one immersion element at the top of the cylinder and a shunt pump to heat the lot or as much as you want.

I am interested to know what their special temperature sensor is. He implied a few sensors. I assume a number down the length of the cylinder.

Quite neat. One immersion element with a shunt pump with a clever computer control board. Quite an advance in that alone. But the grid will periodically charge it up for a little charge to dissipate surplus electricity.

This must be cheaper than using gas for DHW as it now stands. But I see no reason why gas cannot be used with a high efficient coil at the top of the cylinder, or probably a plate heat exchanger using the shunt pump in dual mode. The savings are heating the cylinder top down and as far as you want the hot water down the cylinder. They must also have a pancake spreader for the cold inlet to the cylinder to disperse the cold inlet water to only the bottom of the cylinder. So stratification is not disturbed. That is applicable to any fuel used.

Interesting , smart meters will like it when the day comes when we all are charged by the half hour via the smart meter.
