Weird gas consumption OVO SM
On a Smart Gas meter and able to look on line at the consumption for
year, month, week and individual days... We are away from home this week, boiler is off, we have no pilot lights so their should be no gas used. The weekly shows the consumption for the day we left, then 0.05kw 0.29p each day since. The graphs for the individual days, logged every 30 minutes show a bar, but zero actual consumption. I do a regular drop test and the SM installer did his own test when fitting the meter, so I'm pretty sure we don't have any leakage, but.... Is there a fault with OVO's online calculation or display I wonder? |

I have assumed it is the boiler function to keep a small reserve of ready heated water so it occasionally fires up to do this. Not tried fiddling ith the settings to confirm that - .5p a day is not a large part of the bill... Chris K |

What happens if you actually turn off the gas supply at the main tap? Turning the valve off at the meter will be my next thing to try, but not until next year. To answer the other question - The boiler, timer and water valve have all of their power isolated. The timer is battery backed, so its an easy way to not waste gas heating water up twice a day, when we are away, without changing the timer. |

If I've done me sums right (admittedly an "if" that probably deserves to be in 36pt Arial Black) that's a loss of about 4 litres of gas per day. IIRC that in turn is about what you'd typically have in your pipes. So unless you do your tightness test for a *lot* more than the usual 2 minutes I'd be surprised if it'd pick up that rate of loss. -- Robin reply-to address is (intended to be) valid |

Ovo charge 28.77p per day standing charge for the meter, this is why you are seeing zero consumption. |

No, the standing charge is 27.4p per day. According to their website, there's only two different standing charges for gas, one is 28.77p per day, this covers a few different tarrifs. The other is over 35p per day for a different tarrif |

Although you say it was turned off, was that completely or just the thermostat cause if not it would fire up ocassionally for the reservoir tank to pre heat warm water for the taps. |

ss brought next idea :
I am also on 27.4 per day with OVO. Although you say it was turned off, was that completely or just the thermostat cause if not it would fire up ocassionally for the reservoir tank to pre heat warm water for the taps. The entire heating system was completely isolated from all power, no doubt about that. |

It happens that Roger Mills formulated :

It seems a bit of a coincidence that 27.4 + 5% = 28.77 which is the figure quoted by others for the standing charge, and pretty close to your 29p per day "consumption". It took some digging to find out, but yes the 27.4 is ex-VAT. Nowhere I could find, suggested that the consumption figures included the charge for the meter. |

Having said that, I was assuming that 0.29p meant zero pounds and 29 pence. If it actually means a fraction of a penny, that would make slightly more - though far from exact - sense in terms of the alleged "consumption". [0.05 kWh @ 2.43p/kWh would be around 0.12 pence, not 0.29 pence. I'm now more confused than you are!] -- Cheers, Roger ____________ Please reply to Newsgroup.

I don't think a rounding error would account for a factor of nearly two and a half! And I'm still not sure whether your 0.29p is £0.29 or £0.0029 Which is it? -- Cheers, Roger ____________ Please reply to Newsgroup. Whilst email address is valid, it is seldom checked. |

As an aside, I use OVO and I have a spreadsheet I use to compare my estimate with their bill each month, I got the formulas from OVO and I can get within a couple of pence per month accuracy. Due to my lack of excel knowledge when I put in at the start of the month my readings, the way it calculates is it gives me the months standing charges plus whatever gas I have used so my bill appears high at the month start but catches up as the month progresses and the accuracy at the month end is spot on. Totally different to what you are saying with a smart meter but I was also caught out initially with the daily charge the way I have formulated it. |

Sorry, it is 29p or £0.29 OK, so the bulk of that is the standing charge, even if that's not clear from the information it provides. Whether or not it is *also* showing some consumption, I'm not sure. If it's 0.05 kWh per day, that would only account for about 0.12 pence - so your standing charge of 28.77 pence would round up to 29p regardless of whether or not the 0.12 pence were added. -- Cheers, Roger ____________ Please reply to Newsgroup.

Prior to the SM's I used an Excel spreadsheet which I found and adapted to weekly readings. It was excellent. |
