Saving economy 7 electric with batteries.

kwikbreaks

As an aside...

The economy seven tariffs were first introduced along with storage heaters (concrete blocks that are heated up overnight and you hope in vain will still be hot enough to warm the house throughout the following evening).

Given the extra service charge and considerably higher daytime rate on most tariffs they are not economical at all for most people unless they still use storage heaters.

I would recommend anybody on an economy 7 tariff who doesn't have storage heaters to do some simple calculations as they are almost certainly wasting money and should get their meter changed back to standard.

I have, and have had, E7 storage ] both water & heat ] for the last 35 or so years in three different houses. Accepting the standing charge con I pay Night = 4.619p per unit for leccy on my price plan, that's less than five pence per unit. I have no idea on other energy costs but 25p per unit [ 5 times higher ] would be a guesstimate I'm happy with. Most people including my own close family members go a sickly kind of yellow green colour when these costs are mentioned.

My energy is so cheap I'd rather overheat [ can't turn them on daytime ] and open a window or two to cool the house, than set them low and turn on any ancillary [ boost heat during the day ] form of warmth.

- nowt wrong with E7 radiators / water heating.

To calculate that I would need to know

1) The size of the hosepipe in mm
2) The volume of water ejected per minute
3) The distance the water will "fall" before hitting the turbine

Actually its an interesting thought. But such a waste of treated water.

"" change their meter changed back if you don't have storage & water heaters "" I agree 100%, but for balance see #13

So far we have not had a water meter imposed on us, could the experts above work out how much electricity we could generate if we used cold water piped through a hose out through the upstairs bathroom window to turn a water wheel or turbine generator?
Perhaps this small but constant source of energy could be used to charge batteries to cope with bursts in demand like boiling a kettle etc...
Yours hopefully

Someone please tell me that this guy is taking the P.

it doesn't matter you are using electricity to pump water to produce less electricity, to charge some batteries that will give out less electricity than it took to charge them

if there was anyway to produce electricity for free then everyone would be doing it.

the losses come from any noise, heat or general efficiency losses throughout the proposed system.
