However, I do record our electricity consumption twice a day, around 8am and 5pm in Winter and about 7-8pm in summer. We have oiled-fired central heating, which is on most evenings now. There are two of us at home all day and we have a 4 bed bungalow.

Average daily (24hr) consumption of electricity:

Summer (May-Sept 2011) 8.6kwh
Winter (Oct-Mar 2011/2) 11.6kwh (3.84kw PV installed 4/10/2011)
Summer (Apr-Sept 2012) 4.6kwh (note the drop in consumption from previous summer. The PV is doing something)
Winter (Oct- to date) 9.2kwh

I did start to get worried with a few frosty nights and his bathroom being built on the back - he has no central heating. But the house does not feel cold. I assume his neighbours houses are keeping it warm with the two great hunking party walls acting as low temperature emmitters. I wonder how much heat he "benefits" from if his room temperature is a few degrees lower than his neighbours :bigsmile:

The solution, oddly enough, was calibrating the thermostat down a couple of degrees so what showed as 21 was really 19 (although I have no idea of accuracy, it could have been 20 in reality) . this was a digital stat and it actually had a calibration menu :)

The point being the need to set the stat to 21 was behavioral rather than based upon need for that temperature...]]> Neighbours Energy Usage http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9794&Focus=161028#Comment_161028 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9794&Focus=161028#Comment_161028 Fri, 09 Nov 2012 14:32:44 +0000 SteamyTea Neighbours Energy Usage http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9794&Focus=161045#Comment_161045 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9794&Focus=161045#Comment_161045 Fri, 09 Nov 2012 18:40:53 +0000 skyewright Posted By: SteamyTeaTrouble is now it is getting towards the technological fixes as I have done the easy stuff, but have saved around 50% in total.
I thought we'd probably just about run out of savings at around 7.5kWh/day but with the latest change (1 big and fast but efficient computer using virtual machines doing the jobs of 3 older slower & less efficient ones) we managed to average a usage (not import) of less than 6kWh per day for the first time last month.
That's down from 12-13kWh/day back in 2008-9.
2 adults, at home most of the time.
N.B. excluding heating, of course...

PS. The downside of the computer change is that without the saved watts I'm definitely going to need a heater on more often in my office this winter...

Cooking requires a change from using the oven to the hob or the slow cooker as it is getting too cold for salads.

We have changed about about 40 50w halogens for 4w LEDs but we are still left with the living room lit by 33 10/20w G4 bulbs. I haven't seen any decent living room LED lighting, at least, not down here in Cornwall.

We are also exploring changing our heating system from oil but that will be expensive.

I manage it, but usually in to go out and get it when it rains. Raining now.

Posted By: MikelWe have changed about about 40 50w halogens for 4w LEDs
I decided not to go down this route, but have changed from 20W, to 11W and now to 8W CFL and really do not have a problem, and I have very strange eyesight since my cataracts were drilled out and replaced with shiny bits of plastic without any UV filtering. I actually find the blueness of some LED quite painful. I changed the lodgers 11W to an 8W last week and she has not said anything, 2 quid each from MacSalvers.

Think that is where I am now, could save a tiny bit on the fridge, not sure about the washing machine, 30 kg of water heated to 40°C is the same with any machine. ST is my best option for water heating, that would save quite a bit, but not really worth the expense on this house at the moment as I want to move.]]> Neighbours Energy Usage http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9794&Focus=161070#Comment_161070 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9794&Focus=161070#Comment_161070 Fri, 09 Nov 2012 22:00:02 +0000 Triassic Posted By: SteamyTeaI still struggle with my lodgers behaviour, but she is a special case (only a third of her brain works).

The word 'ration' makes you think of wartime, hardship, disaster. If they had said 'manage' it would not have been much of a headline. And I think that's all they are really saying.

In my humble opinion most households still don't manage their energy use nearly as well as they should.

And what about the 1 household in 10 which, we can only assume, makes no attempt to manage energy consumption at all?]]> Neighbours Energy Usage http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9794&Focus=162058#Comment_162058 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9794&Focus=162058#Comment_162058 Fri, 23 Nov 2012 09:37:53 +0000 SteamyTea
So

House A 452 (end terrace, 2 adults, 1 small child)
House B 192 (mid terrace, 2 adults)
House C 276 (mid terrace, 2 adults)

The day/night breakdowns is:

House A 149(day) 303(night)
House B 58 (day) 134(night)
House C 108 (day) 169 (night)

So our average usage is 306.6 or 21.9 kWh.day^-1
Average day usage is 105 or 7.5 kWh.day^-1
Average night usage 202 or 14.4 kWh.day^-1

So looks like House C does not have their heating on, or they have an electric shower as we are similar on the night rate.
House A has heating on and I have never seen them use a washing line, so probably using a tumble dryer a lot.

As an aside, my Current Cost meter (with a couple of estimates in there) says I have used 177 kWh over the same period, so about 8% down on my real usage. May check my voltage over the next few days and see if it is high or low compared to the set point of 230V.]]> Neighbours Energy Usage http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9794&Focus=163358#Comment_163358 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9794&Focus=163358#Comment_163358 Sun, 16 Dec 2012 19:58:34 +0000 SteamyTea Seems mine is creeping up a bit.

If you do then the heater is "filled up" one night and used the next day. If you have a cold day, then that night maybe a full charge is required. On a warmer day if you only use half the stored heat on that night you would only need to store half the amount of energy/heat. So overall the electricity used would approximately follow the outside temperature variations.

I have very detailed usage data that I will unpick sometime soon, but is could be that we have been using more hot water and the header tank is in the loft, so that will be colder than in the autumn.

Partly because the heater is set on a thermostat (though not sure how effective it is),
I think it's pretty effective at limiting the temperature inside the casing, which is what its job is.


partly because it has been 'de-rated', I took two elements out

Fair enough. That will make it more likely that it needs to be on throughout the charge cycle (as it's trying to warm 3 times the intended mass (I'm assuming there were 3 element to start with).

and mainly I think because when it is warmer outside my house just gets warmer inside.

4, 750W elements, now two in the middle. In the past the air used to exit at over 85°C (fried an iButton checking it), seems closer to 70°C now, but not actually checked it. Something to do.
