Storage Heaters E7 ( me again)
I cant follow this, maybe someone with a qualification can do the maths and
tell me if its right? I put on one of the storage heaters last night ( not the new one, it hasnt been fitted yet). I have checked the meter daily so I know my electric usage each night is between 15 and 17 units WITHOUT the storage heater(s) on. I am charged at 5 p a unit ( kw?) I put one 3.25 kw capacity storage heater on last night. The electric meter read 82 units used overnight. Now if I take away the 17 I would normally use during the night for my essentials and drabs , that means the heater used 65 units over night. That means the heater cost me nearly a fiver to have it on for one night. Is my maths correct? Is that right, should a 3.5 kw heater running for 7 hours on economy be using that much electric? Does that sound right to you? Just need to know. I am clueless and confused totally. |

Correct, 1 Unit = 1 kWh So, 3.5 kw x 7h = 24.5 kWh /units Assuming the storage heater was on constantly (i.e. not cycling on a thermostat, which I'm guessing is an invalid assumption). |

I have chest problems and I was struggling without the heat. I had thought I had found the source of the problems in another heater but it looks like they have all been using the same - 65 units per heater per night. No wonder I had that high bill!

Well..... it should have been cycling on a thermostat and should only have charged up 2/3 but it seems to have used 3times what it should have doesnt it? Thats why I am asking. I thought I might have not understood it right. |

But I just cannot see how it can do this. I set the heater input control at 4. I set the output at 3. The heater has warmed across the top and the bottom is cold. So its not heated up the storage capacity. Anyone offer anyexplanation? Anyone experienced this? |

First, your meter is crap. But it was possible it was happening on the last meter too ( no way of knowing because the meter never got read properly even my the meter reader). I am supposing by deduction its not the meter since it seems accurate enough for all other appliances . After all it wasnt hiking up high readings for my night rate before I put the heater on. Second, something, somewhere *is* taking that electricity. Is it possible that immersion heater, neighbour's heating, the local street lighting or something else is connected? (LOL - if I didnt I would cry) . The immersion heater has always been on. It was part of the 17 overnight figure I quoted as the base rate for my supply. I live in a detached house ( bungalow) and I cannot believe my neighbours heating would rush me that much when they have coal for their heating anyway. I dont think thats posible ;-) There is no street lighting. If the heater is taking that much in, it must be getting very hot - so no, I don't think it is the heater itself. (Again, assuming the rating is correctly reported.) But its not getting hot. I am not under reporting I promise you. There is something up with the storage heating obviously but I cant see what and its driving me mad. I asked for help as some will recall a bout a month / six weeks ago when I got a meter reading and a 240 quid a month bill ( with just one heater on - not this one another heater.) I switched everything off and I had to put the heater on last night because I cannot cope with the cold/ damp any longer. I am asthmatic ( result of lung problems after having pneumonia) But I cant afford this bill either. If its going to take 65 units a night, I cannot keep affording it. And what about the rest of the house? I have three of these heaters, one 2kw heater and tow 1.7kw heaters ( so called) are they all consuming the same? I dare not even put them on to find out quite honestly! |

Are you certain that nothing else inside the dwelling is getting hotter? I am absolutely certain nothing else is getting hot or seems to be switched on. I have a fridge, freezer and one low energy light bulb ( 60 equivelent in normal lights) running all night. The dishwasher is programmed to come on at 4,00 am and wash up for an hour and the immersion heater is time switched for two hours each night. All of these (and a washing machine twice a week) have used no more than 17 units overnight every night for the last six weeks. The day usage ( when I am out anyway) stands steady at about 5 units ( unless I cook a lot in which case it goes up to 10 units) . When I put the heater on last night it went up to 82 units used in off peak time. Nothing different on. "Do you have any circuits feeding outside buildings? When the "normal" consumption was taking place where were the off peak heaters switched off - at each individual unit adjacent switch or at the off-peak consumer unit main switch?" Whatever it is is not heating anything because the house is bloody cold! Thats why I was forced to put heating on. There are no outbuilding with anything on. Even if there were, it would be no more than a 60 watt bulb since my only outbuilding is a toilet ( outside) and the only electric supply in there is a 60 watt bulb. All the heaters are switched off individually at their own socket ( whatever its called - the box which connects them to the electric supply situated at the side of each heater. When I put the neater on last night I switched that one heater on. All the others were off ( and one is missing all together because I had it taken out when it seemed faulty and haven't put a new one in). None of the other heaters are getting anything other than stone cold. There is nothing apparent on. There is nothing else to be on. Thats what I cannot understand. I cant even see an electrician picking this one up ( not to mention the cost and worse finding one!!! Despite everything when you want an electrician all they want to do is small simple jobs , not hunt down my problems. Even asking one to come and look at a storage heater which wasn't working was too much! A result of Maggie and her privatization of utilities. No electric board , no electricians who will do the work! - sorry about the rant) I don't know where to look for something that could use that amount of electric . I only live in a two bedroom bungalow. Hardly a mansion and no fancy appliances or anything. |

The meter measures Kwh. If it's going into the heater those Kwh have to represent energy dissipated in the heater one way or another. As heat stored or released would be typical.

It sounds to me like your meter might be faulty. What I would do is: First, turn everything off - turn the main switch off if that's easiest. Check the meter. If it's mechanical, the wheel in the middle should be stationary, if it's digital the red LED should not flash at all. If this isn't the case your meter is feeding something else (or is seriously broken). Next, find something with a constant load - an electric heater (not a storage heater) is probably good, but make sure it doesn't have a thermostat. Note the meter reading, then turn on just that one device. On a mechanical meter you will have a "tenths" dial, which makes things easier - a digital meter might not. Run the load for a fixed time - say an hour, or half an hour, then switch it off. Work out how much power you should have used - the power in kW times the time in hours - and check that the meter has gone up by that much and no more. If the meter has gone up by more than it should, and you're sure you didn't put anything else on, the meter is over-reading. Call the electricity company and get them to check - and if they find it is wrong, don't forget to ask for a refund back to when they installed it. Mike |

I have checked the meter daily so I know my electric usage each night is
between 15 and 17 units WITHOUT the storage heater(s) on. I am charged at 5 p a unit ( kw?) I put one 3.25 kw capacity storage heater on last night. The electric meter read 82 units used overnight. This might be a daft question, then again... I don't think this applies to you unfortuately :-/ Are you on a pre-payment meter ? - if so, it might be that the rate it clocks up costs is higher than your true usage (it's a programmable rate). AFAIK the dial / display will read the true number of units, but the maths behind it are skewed for prepayment meters, so you may have (for the sake of ease of numbers) used 100 units at 5p/unit, but you can be charged a variable rate over and above the true usage, i.e. you might be getting charged at a collection rate of 7p/unit - this is often done for people who have a debt on their account. |

When I put the heater on last night it went up to 82 units used in off peak time. Nothing different on. The 17 units figure seems suspiciously high. Without storage heating or an immersion heater, we average less than 4 units per night - and this includes two freezers, a fridge, and dishwasher and washing machine (both elderly) each run, say, 4 times/week. Add in your 2 hours of immersion heater, 6 kWh if the thermostat doesn't kick in, and it would still only come to less than 10 units. Our daytime use pattern is sufficiently different to yours that comparison is much harder, but we average 9.5 units/day in summer, which includes the freezers, PC all day, power tools, electric oven, etc. As others have suggested - time to check the meter with a known simple load and _everything_ else turned off - even the fridge and freezer for an hour. -- Kevin Poole ****Use current date to reply (e.g. )**** |

If you are unable to identify something which is doing this then I strongly suggest you engage the services of someone with the knowledge, equipment and ability to track it down. Are you certain that nothing else inside the dwelling is getting hotter? I am absolutely certain nothing else is getting hot or seems to be switched on. *I have a fridge, freezer *and * one low energy light bulb ( 60 equivelent in normal lights) *running all night. *The dishwasher is programmed to come on at 4,00 am and wash up for an hour and the immersion heater is time switched *for two hours each night. All of these (and a washing machine twice a week) * *have used no more than 17 units overnight every night for the last six weeks. The day usage ( when I am out anyway) stands steady at about 5 units ( unless I cook a lot in which case it goes up to 10 units) . When I put the heater on last night it went up to 82 units used in off peak time. Nothing different on. "Do you have any circuits feeding outside buildings? When the "normal" consumption was taking place where were the off peak heaters switched off - at each individual unit adjacent switch or at the off-peak consumer unit main switch?" Whatever it is is not heating anything because the house is bloody cold! Thats why I was forced to put heating on. *There are no outbuilding with anything on. Even if there were, it would be no more than a 60 watt bulb since my only outbuilding is a toilet ( outside) and the only electric supply in there is a 60 watt bulb. All the heaters are switched off individually at their own socket ( whatever its called - the box which connects them to the electric supply situated at the side of each heater. When I put the neater on last night I switched that one heater on. *All the others were off ( and one is missing all together because I had it taken out when it seemed faulty and haven't put a new one in). *None of the other heaters are *getting anything other than stone cold. There is nothing apparent on. *There is nothing *else to be on. *Thats what I cannot understand. *I cant even see an electrician picking this one up ( not to mention the cost and worse finding one!!!

I only live in a two bedroom bungalow. Hardly a mansion and *no fancy appliances or anything.- Hide quoted text - - Show quoted text - Where are you that electricians are so hard to come by? Can you get your hands on a clip-on amp-meter from ebay if nothing else. This would enable you to check the current drawn by the heater. It will require access to one of the individual Line or Neutral wires inside the cable or local isolating switch (beware of the little men running up your arm). A 3.4kW heater should be drawing around 14.2 Amps but if the supply voltage is nearer 230v than 240v which would be the basis for an older model it will be lower around 13.6 If the heater is the culprit a higher current would be passing. The type of fuse or circuit breaker at the supply will influence how much current can actually pass without operating (blowing) the fuse or tripping the circuit breaker. An old rewirable fuse rated at 15Amps will pass close on 30Amps for hours without operating so you cannot rely on the fuse recognising a defect. I'm still suspicious of a branch off the circuit which you do not know about. Checking the current passing out of the fusebox to the heater and comparing it with the current arriving at the heater would prove this one way or another. You could also monitor the current in the meter tails as you switch loads on or off although for off peak this will involve going to bed late or getting up earlyg |

The electric co (private or public) have only ever supplied houses with an electric supply. What you do with that supply is up to you. I don't know where to look for something that could use that amount of electric . I only live in a two bedroom bungalow. Hardly a mansion and no fancy appliances or anything. Turn everything off (I mean everything), and then turn on one known load, ie your heater. The meter will show how many units per hour the heater is using if this is the only appliance turned on. It should take you one hour at an inconvinient time of the day and you will need a torch. Adam |

Don't fret, now the government has started a recession there will be plenty of out of work plumbers, brickies, electricians and every other trade looking for jobs to prop up their benefits. Anyway all your problem needs is a bit of common sense and some test kit. Think about buying one of these http://www.ethicalsuperstore.com/pro...FRqH1Qod821FWg Its a simplified clamp on meter that works out how much power you are using. Then you can just turn stuff on and off until you find the problem. You don't have to put the sensor around the meter tails, you can fit it around any circuit if you want. |

Apparently it will wack three times the electric if it stops working. So we think its the heater still. Some misunderstanding here, I think. A fault in the heater causing it to draw three times the rated current is conceivable (short-circuit across part of an element) but very unlikely in practice. If such a fault did occur then your 24 kWh (3.4 kW) rated heater would be taking over 10 kW and over 40 amps. If it's properly wired a fuse would soon blow or a circuit breaker trip. If the fuse has been replaced with the proverbial 6 inch nail then one of two things will happen next: either the fault will clear itself as the remaining segment of element burns out, or the fault will turn into a short-circuit. In the first case the heater would then either be completely dead or would work at reduced power. In the second case the fuse or MCB would then finally blow or trip, or else the wiring would catch fire. A sustained fault whereby the heater draws over 10 kW night after night really is inconceivable. If your overnight consumption really is 65 units - an average of over 9 kW over 7 hours - then a lot of heat must be going /somewhere/. Are you sure you're reading the meter correctly? -- Andy |

I suppose it depends where you live to an extent but I know there are electricians but they simply dont want the kind of work we are talking here.

They tend to be expensive and often no show or " terminators" - all be back - b ut they never do come back. High costs and high taxes make it impossible to make a living travelling out to do small jobs. A tradesman can bill out about 1,000 hours per year the average salary is over £25k, the tradesman has overheads, hence I have to pay about £220 a day or part thereof for a joiner. What we seem to have a lot of ( and dont need in my area) is IT and web designers and salesmen for double glazing etc ( and no workmen once they get the orders!) and graduates in naff subjects are ten a penny and working in Tesco and co op stacking shelves.

I have a feeling they might have got the wrong end of the stick in a short telephone call. Apparently it will wack three times the electric if it stops working. If the input thermostat sticks closed it would draw current the whole time it was energised that might in some circumstances equate to 3x the energy consumption, but the heater would be getting very hot. So we think its the heater still. I think you have some more observations to make. But I shall let you know when we have done all the working out. Derek |

No, for storage heaters the rated input power (3.4 kW in this case) is equal to one seventh of the rated heat charge (24 kWh). For a full charge from cold the thermostat will remain closed for the whole 7 hr period. The consumption in 7 hours will not exceed the rated 24 kWh, give or take small tolerances on the element resistance and supply voltage. -- Andy |

Although to be fair by 3x the energy consumption I did mean 3 x the steady state consumption IE a heater with some residual heat and the thermostat set low (bit of an unlikely combination). A shorted input thermostat was the fault condition I thought the manufacturers helpline guy could have been on about. I can't think what else, can you ? Derek |

As I said earlier you can imagine a partly shorted element causing an increase in input power, but any such fault is likely be quite transient for the reasons I gave. Also all storage heaters I've ever had anything to do with have a second overheat protection 'stat (with a non-self-resetting cut-out action) in series with the mains input. Anything causing a ~3 kW heater to draw 9-10 kW is going to cause that to trip if none of the other outcomes I mentioned apply. -- Andy |

I cant follow this, maybe someone with a qualification can do the maths and tell me if its right? I put on one of the storage heaters last night ( not the new one, it hasnt been fitted yet). I have checked the meter daily so I know my electric usage each night is between 15 and 17 units WITHOUT the storage heater(s) on. I am charged at 5 p a unit ( kw?) I put one 3.25 kw capacity storage heater on last night. The electric meter read 82 units used overnight. Now if I take away the 17 I would normally use during the night for my essentials and drabs , that means the heater used 65 units over night. That means the heater cost me nearly a fiver to have it on for one night. Is my maths correct? Is that right, should a 3.5 kw heater running for 7 hours on economy be using that much electric? Does that sound right to you? Just need to know. I am clueless and confused totally. Just a thought: Everyone's replies have assumed that you are reading the meter correctly. Is it possible that you may have misunderstood how to read it? Perhaps you could tell us more about the meter, its display and how you are reading it? Remember that it will probably display tenths of a unit so it's quite possible you have only used 1/10th of what you think. Now 6.5 units is 6.5kWh which could well be consistent with a 3.25kW storage heater on a 2/3 setting. It will use 1 unit every 20 minutes - but only while the internal thermostat is calling for heat which will only be intermittent. So that would mean it was calling for heat for a *total* of about 2 hours. Sounds about right. Whatever is going on don't panic, there must be a fault in your logic rather than the meter or the heater. If you really were consuming that much power you'd know - the house would be roasty-toasty-plus- plus. -- Calvin |
