    Hi lads,

    I want to get a device which will allow me to monitor and help me to reduce my electricity consumption. I've a house of kids who seem to be forever consuming electricity via xBox, TV's and computers etc as well as lights left on etc.

    Is this the best/most appropriate device to get so I can track usage over time and perhaps set and compare usage targets etc? http://www.amazon.co.uk/Owl-Connectivity-CM160-Wireless-Electricity/dp/B0041H6VXI/ref=cm_cr_pr_product_top

    Cheers,

    Ben

    Guys,

    I got the Owl + USB and am ready to install it but I'm not much of a DIY'er, especially when it comes to electricity :o

    Would someone mind telling me which cable I'm supposed to clip the sensor to in the photo below?

    Thanks for your help.

    The red one


  • Moderators, Home & Garden Moderators, Technology & Internet Moderators, Regional East Moderators Posts: 12,650 Mod ✭✭✭✭2011


    The red cable, or the black or either of the 2 grey cables (the singles) would do fine. Personally I would go for one of the grey singles as they have plenty of slack.

    I tried it on both grey cables and it seems to work. I'm confused that it cab work on more than one wire. Are several wires bringing power into the metre or is that a stupid question? I just don't understand how up to 4 wires can track my usage.

    The current drawn by the house is supplied by one of the grey single cables, this connects to the red core of the T & E downstream of the ESB meter. The same current then returns on the black core of the same T & E which connects to the other grey single cable. At any given time a current of the same magnitude can be measured at any of these 4 points. I hope this makes sense :)

    Didn't understand a single word of that but I appreciate the fact you tried. I'm a total cretin when it comes to electrical and plumbing :o

    :D:D

    Not to worry, install it on either of the grey single cables and if it provides a reading you are sorted.

    Basically current in = current out, and any of the 4 cables metioned above are either bringing current in or out.

    So,

    I've had the Owl installed around 24 hours. The minimum hourly cost I've observed at 7am this morning before anyone got up so no kettles, ovens, TV's etc on was 14c per hour and the max I observed was also this morning when breakfast was underway so grill on, lights on, TV on etc was 70c per hour. It's just under 15c now. I'm the only one home so no TV's, no washing machine, tumble dryer, oven etc.

    My Airtricity bill from Oct 23 to Dec 22 was €608 which implies an average hourly rate (€608 / 61 days / 24) of 41.5c per hour. I've a 2,000 square foot house with 3 adults and 2 kids living in it. Our central heating, hot water and (non oven) cooking are supplied by natural gas which for the period Oct 17 to Dec 10 was €250. That's €850 for two months which seems mad expensive to me. Last year we used a total of 13,800 kWh electricity. Don't know how much gas we used.

    Some things I would appreciate your help with:-

    1. Any special tips for reducing the amount of electric units we use? (Already turning off all electricals like TV's, computers etc rather than just letting them "sleep")

    2. My 12 month deals with Airtricity and Flogas ended in mid December. Airtricity moved me from Home Elec Saver 24hr where the unit cost was 14.25c to SmartSaver Std 24hr with a unit cost of 16.46c. My next Flogas bill will probably show them changing me from my 12 month deal which is 4.5c per kWh + carbon tax of 0.37c per kWh to something higher also. IS Bonkers.ie the best place to find out where I should be moving to next to take advantge of new customer discount etc?

    3. What average cost per hour should I be aiming for with my electricity consumption given current rates and my circumstances i.e. house size, using gas for heating and cooking etc?

    4. Is there an option to get a more modern meter which would allow me to take advantage of "NightSaver" rates and if so is it worth getting?

    BTW, here's a shot of how I ended up fitting the sensor

    za1y.jpg

    And here's one of the display unit.

    j0kc.jpg

    If anyone spots anything wrong with my set up please let me know!!

    Regards,

    Ben

    Ben,

    Its easier it you talk in kWh. people pay different prices. kWh is the denominator.

    your bill does indeed appear high. However your with Airtricty and I take any bill from them with a pinch of salt as from my professional opinion they are pretty hopeless. Have they used actual meter readings or estimates to generate your bill?

    Lighting accounts for 40% of domestic bills, you should look at changing out all your lamps/bulbs. the initial cost is high but the payback is in months not years.

    Bonkers.ie is a good price comparison site to use to find the best supplier.

    Unless you have storage heaters or use over 3kwh during the night period then the night period doesn't offer any saving ( these figures may have changed in the last year)

    That is very high.
    I would not accept that in my home.
    My Airtricity bill from Oct 23 to Dec 22 was €608

    That is crazy! Was the bill estimated or did you submit readings?
    1. Any special tips for reducing the amount of electric units we use? (Already turning off all electricals like TV's, computers etc rather than just letting them "sleep")

    Big consumers of electricity include:
    Immersion
    Oven(s)
    Tumble dryer

    Modern computers and TVs consume very little power.

    A few things to look at:
    1) In terms of energy efficiency how are your appliances (AA or AAA) ?
    2) As already suggested what type of lighting are you using? Multiple 50W down lighters will add up quite quickly. Have you considered / do you have LED lighting?
    3) I found that it is much more cost effective to have lots of clothes and not use a tumble dryer.
    4) Don’t use an immersion! It is cheaper to heat water with gas.
    5) Avoid using electric heaters.
    6) Try to identify why your home is consuming a minimum of 14c per hour. This seems very high to me.
    7) How many fridges & freezers do you have?
    IS Bonkers.ie the best place to find out where I should be moving to next to take advantge of new customer discount etc?

    Yes.
    To get the best deal you need to change supplier regularly.
    3. What average cost per hour should I be aiming for with my electricity consumption given current rates and my circumstances i.e. house size, using gas for heating and cooking etc?

    Hard to say.
    My combined energy bill (gas & electricity) is about €140.
    This is for a 4 bed house with 2 people living in it.

    4. Is there an option to get a more modern meter which would allow me to take advantage of "NightSaver" rates and if so is it worth getting?

    Only if you can change your usage around to suit. For example use the washing machine, dishwasher, tumble dryer etc. at off peak times.
    BTW, here's a shot of how I ended up fitting the sensor
    Looks good.

    Getting the Owl is my first step towards diagnosing what's costing so much and dealing with it so I concur, I DO NOT accept that my usage should be this high!!

    The bill was estimated but having checked the meter shortly after the bill arrived the estimate was pretty close to being correct so for the purposes of this discussion we can take it that the bill was accurate to within 3% or so by my calculation.

    - Don't use the emersion except in an emergency
    - The oven gets used a good bit, every second day or so for about an hour e.g. roast chicken, fish pie etc.
    - The tumble dryer is probably a major contributor. It gets used every day. I need to address that somehow.

Have you considered / do you have LED lighting? - The house is almost totally lit by 50w downlighters installed in 2005. See the photo below. Can these be replaced by energy efficient long life bulbs or LED's or something which eats less electricity but still gives good light? I don't want to go back to the days of those horrible white flourescent tubes though!!!

    5) Avoid using electric heaters. - Don't have any.
    6) Try to identify why your home is consuming a minimum of 14c per hour. This seems very high to me. - The big thing I can think of is I have a 500 Litre tropical fish tank which maintains a constant 26C temperature, has an air pump working 24/7, two internal filters sucking in and blowing out water 24/7 and two flourescent tubes lit up 6 hours a day or so. Apart from that there's 3 TV's, 3 UPC boxes, a PC, two broadband routers two laptops, a tablet, two games consoles, and 5 phones many of which are charging 6-8 hours a day. I guess all that's going to consume 14c an hour??
    7) How many fridges & freezers do you have?
    - One US style fridge freezer and one old fashioned cabinet freezer in the shed.

    I don't think I'd get much benefit from having a night meter unless the fish tank is eating up that much?? What time do the NightSaver rates kick in and how much of a discount do they typically offer? Are they only available from Electric Ireland?

    Here's a photo of one of the 57 (I'm not joking, I just counted them!!!)) downlighters in my house

    A conservative estimate of say using just half of those lights for 6 hours a day will account for €100 of your bill. If more of those are on for longer...you can scale that up to maybe €300 very quickly.

    It's definitely a huge culprit I would reckon.

    Using clothes horses etc for drying clothes can help on the dryer front.
    Not much you can do on the oven - you have to cook, and your use isn't too bad anyway.
    Not much you can do about the fish cost either.
    Nightsaver not much use as you are not heating water etc at night.

    That's the figure used by seai and others. It may be sightly out dated as based on older incandescent lamps and halogen down lighters. A 100w bulb may be on for 8 hours a day where as a 2kw kettle may only be on for 9 minutes. Then there is other lamps.

    As above the OP has 57 down lighters changing these out will reduce his bill.


    Ben, do these bulbs have spikey pins (MR16 fitting )in the end or do they have round chunky ends. (GU 10 fitting)?
    If they are the latter then its a very easy job to swap them out for LED lamps. If they are MR16 you may need to get a sparks to swap them for you.

    My misses was slow cooking a pork over three days. The grief I was giving her over the oven being on ;) nearly swapped over to night rates then ;)

    3 days:eek:! Hope it tasted good! If you swap over to nightsaver, the day rate becomes more expensive. So unless you have a decent percentage of usage at night (eg. water heating), then it's not worth changing for. The standing charge is also higher for nightsaver.

    Good.

    We all have to eat, not much you can do to reduce oven use.
    If you have a double oven perhaps you can use the smaller oven more often (if possible).
    - The tumble dryer is probably a major contributor. It gets used every day. I need to address that somehow.

    This would represent significant portion of your bill.
    Turn on the tumble dryer and watch the price on the Owl change.
    A quick calculation based on the Owl increase and you will be able to estimate how much this is costing you per bill. Remember to double whatever number of hours you are told it is on for ;)

    What about a clothes line, clothes horse, hot press?
    I can understand occasional use of a tumble dryer (once every week at most) but every day is crazy.
    I don't think I'd get much benefit from having a night meter unless the fish tank is eating up that much??
    The fish tank will be on 24/7 so dual tariff is of little advantage for this load.
    What time do the NightSaver rates kick in and how much of a discount do they typically offer? Are they only available from Electric Ireland?
    Have a look at typical rates here.

    1) More energy efficiency appliances cost more to buy, but they can be significantly cheaper to run. With a bit of help from Google you should be able to find out which of your appliances are least efficient. The appliances to look at includes, tumble dryers, washing machines and fridges. If any of these are particularly inefficient perhaps you should consider changing them.

    Have a read of this.
    2) The house is almost totally lit by 50w downlighters installed in 2005. See the photo below.
    :eek: :eek: :eek: :eek:
    Can these be replaced by energy efficient long life bulbs or LED's or something which eats less electricity but still gives good light?
    Absolutely, check out the sticky above.
    This is a quick non messy job.

    I changed my 50W halogen down lighters for 3W LED lamps.
    Now the cost of running each of these lights is reduced by 94%

    Have you any outdoor 500W halogen sensor lights or similar?
    I don't want to go back to the days of those horrible white flourescent tubes though!!!
    You won't have to.
    3) Not if you had my wife and kids you wouldn't!!!

    No comment :)
    4) Immersion is rarely if ever used. It's purely there as a back up in case the gas doesn't work.
    5) Don't have any.

    Good
    6) The big thing I can think of is I have a 500 Litre tropical fish tank which maintains a constant 26C temperature, has an air pump working 24/7, two internal filters sucking in and blowing out water 24/7 and two flourescent tubes lit up 6 hours a day or so.
    Unplug it for a minute and calculate how much (in terms of €) the Owl drops by. I would not expect this to cost much.
    Apart from that there's 3 TV's, 3 UPC boxes, PC, two broadband routers two laptops, a tablet, two games consoles, and 5 phones many of which are charging 6-8 hours a day.

    All very small loads, but together they add up.
    7) - One US style fridge freezer and one old fashioned cabinet freezer in the shed.

    First of all remember fridges and freezers run 24/7 (although the compressor inside them switches on and off). Ensure that the doors on these units remain open for as short a time as possible.

    I imagine that the US style fridge freezer is large. If this is a "G" rated device it may be costing a lot more than necessary to run. Is it located close to a heat source such as the oven or hob? If so it will be even less efficient.
    Is the fridge running at a cooler temperature than necessary? Perhaps you can turn the temperature up?

    What about the cabinet freezer? Do you need it on all year round? Is the shed cold? How efficient is it?

    Agree with the others, swapping out the lights for led's and drastically reducing the dryer usage and will slash your bill. Show the missus how much you'll save and she'll soon agree with you, especially when you agree to spend some of it on her ;) . Buy some clothes horses and do it the old fashioned way.


  • Registered Users, Registered Users 2 Posts: 4,539 ✭✭✭BenEadir


    Thanks guys,

    I've been away for the last few days so will get focused on changing the 60 (I found 3 more!!) down lighters in the house over to LED's ASAP.

    Any particular suggestions as to what replacement bulbs I should get and from where? Is AMazon/eBay the best place to buy or just the local electrical/lighting shop? I think there is an LED dedicated business in Stillorgan called "Dublin LED" I could try.

    Do you have an electric shower ? They use a heap of electricity. We limited the shower to 5 minutes each, before kids were quite happy to have up to half hour showers, bill reduced dramatically.

    Hi Alf,

    Thankfully I don't have any electric showers so that's one problem I haven't got!

    So, I now know that my downlighters are MR16, 50W, 12 Volt bulbs. A quick search on Amazon identified these as potentially good replacement LED's - http://www.amazon.co.uk/Himanjie-White-Light-Power-Bulbs/dp/B00BEX3B5S/ref=cm_cr_pr_product_top. 10 for £30 delivered sounds very good and the reviews for them are also very good. Any reason I shouldn't go ahead and try 10 of them?

    One more question. I've read that if I'm going to switch to LED's in my downlighters I may have to change my transformer. Is that correct?

    That is one option.
    Most people agree that a better option would be to go for the GU10 (mains voltage type). That way a transformer or LED driver is not required.

    There is an excellent post on the subject from Stoner here:

    Thanks 2011. I just read the post and he says GU10's are "in my opinion a very poor quality and potentially dangerous lamp" :eek:

    I already have 60 MR16 fittings etc so I won't be replacing them in order to accommodate poorer performing (if easier to run) GU10 bulbs.

    It looks like I have to go for the more expensive 7W bulbs if I want like for like replacement in terms of brightness and the ability to dim etc. They're just three times more expensive per bulb :rolleyes: http://www.amazon.co.uk/Lighting-EVER-Dimmable-Halogen-Equivalent/dp/B00EC4R92W/ref=cm_cr_pr_product_top

    My mistake, thanks for correcting me.

    So, with 60 downlighters should I be getting my electrician back to change the transformers and sticking with the WR16 bulbs or have him remove the transformers all together and go with GU10 bulbs?

    My (likely incorrect) reading of Stoners post is that the GU10 bulbs don't produce as much light as the MR16's and if I switch I'd have to replace all 60 of my light fittings also as the GU10 bulbs won't fit into my current MR16 downlighters. That's why I'm thinking of sticking with MR16 bulbs but I'm happy to be corrected - again!

    There are differnet schools of thought on this.
    Like Stoner I feel that it is best to use mains volatge LED lamps that have a GU10 type base.
    My (likely incorrect) reading of Stoners post is that the GU10 bulbs don't produce as much light as the MR16's

    Stoner's point is that halogen type GU10's do not produce as much light as halogen type MR16's. He is correct, the difference in light output is in the region of 40% (for the same energy consumption).


    Very simply put:

    GU10 halogen lamps = Bad :mad: -Power consumption generally 50W

    GU10 LED lamps = Good :) -Power consumption generally in the region of 3W. I suggest that you use "warm white".
    if I switch I'd have to replace all 60 of my light fittings also as the GU10 bulbs won't fit into my current MR16 downlighters.

    In general the light fittings will be fine (if they are flush downlighters such as the one in your earlier photo). Howvere the lamp holders will have to be changed for GU10 types so that LED type GU10 lamps can be installed.

    These lamp holders only cost in the region of €3 each.
    That's why I'm thinking of sticking with MR16 bulbs

    This would mean that you will require an LED driver per light fitting over €10 each I would guess.

    Thanks 2011, you are a fountain of knowledge and very helpful. Much appreciated.

    So from a purely LED perspective the output of MR16 and GU10 bulbs is the same/similar and the cost of the bulbs is the same/similar. The main difference is that the GU10 bulb has a built in transformer which enables it to take a direct power supply whereas the MR16 requires a transformer to be fitted to each lamp.

    If my understanding above is correct my choice is:-

    1. Fit 60 new transformers to facilitate MR16 LED's
    2. take out the existing transformers and fit GU10's.

    #1 requires buying and fitting new transformers which will be expensive whereas #2 requires removing the existing transformers and fitting an inexpensive new bulb fitting.

    Sounds like #2 GU10's is a no brainer.

    Pretty much, yes.

    The main difference is that the LED GU10 bulb can be connected directly to the mains. Whereas the MR16 requires a transformer LED driver to be fitted to each lamp.

    Your choice is:-

    1. Fit 60 new transformer LED drivers to facilitate MR16 LED's
    2. take out the existing transformers and fit GU10's lamp holders for GU10 LED lamps.

    #1 requires buying and fitting new transformer LED drivers which will be expensive whereas #2 requires removing the existing transformers and fitting a inexpensive GU10 lamp holders and GU10 LED lamps.

    Moving VERY swiftly along :D

    Turns out my electrician has been experimenting at home with various LED downlighters (all GU10's) over the last 18 months or so. He has some sort of under shelf lighting in a kitchen and broke it into three sections, one for traditional 50W halogen bulbs, and two for various brand LED's i.e. one brand per section. He'd swap them in and out as new products came available or if he had left over bulbs from a job. He was never that happy with them. Said they look ok but don't throw enough light all the way to the ground.

    He recently (last 4 months) finished a house renovation where the architect had specified Philips downlighters and he said the difference between them and the other (mostly cheaper) brands he had been trying himself was amazing. They really did a fantastic job almost equivalent to traditional 50W Halogen but the bulbs were €25 a pop :eek: I think these are the ones he spoke about http://www.amazon.co.uk/gp/product/B008A25WTE/ref=s9_simh_se_p201_d0_i4?pf_rd_m=A3P5ROKL5A1OLE&pf_rd_s=auto-no-results-center-1&pf_rd_r=0KFRXBA8DWYAW014C1GF&pf_rd_t=301&pf_rd_p=240112507&pf_rd_i=871829112761100

    Since then Philips have introduced a slightly lower watt (5.5 Vs 6) bulb which has better performance and a lower cost of circa €18 http://www.amazon.co.uk/gp/product/B0088YVZP4/ref=s9_simh_se_p201_d0_i1?pf_rd_m=A3P5ROKL5A1OLE&pf_rd_s=auto-no-results-center-1&pf_rd_r=0KFRXBA8DWYAW014C1GF&pf_rd_t=301&pf_rd_p=240112507&pf_rd_i=871829112761100

    As he's the guy who originally fitted my 60 downlighters and I know him socially and through sport he's offering to fit however many of the new GU10 Philips LED bulbs I want, including a new bulb fitting for €20 a downlight all in i.e. including the bulb, fitting and labour on the basis that he keeps all the transformers he takes out which he can then use in small repair jobs he does etc.

    Can anyone comment on the offer? Good or bad? the price of those Philips bulbs seems REAL expensive but then there's no point paying less for cheap bulbs and ending up with not enough light.

    One option I was thinking of was fitting the Philips bulbs in one room and these http://www.amazon.co.uk/Long-Life-Lamp-Company-replacements/dp/B006UR5IUY/ref=cm_cr_pr_product_top which are 1/3 the price in a different room and see what the outcome is. Would there be a noticeable difference? I'm sure if I supplied the bulbs he'd fit them including the new bulb fitting for a €5 a downlight.

    Who would have thought this would be so complex???

    Well then he was using low quality LED lamps. I was not happy with the older LED lamps either, but now I can see that there are excellent LED lamps available at reasnoble prices.

    He recently (last 4 months) finished a house renovation where the architect had specified Philips downlighters and he said the difference between them and the other (mostly cheaper) brands he had been trying himself was amazing.

    I am not suprised. They are vastly superior to many of the low quality LED lamps (frequently from China).

    They really did a fantastic job almost equivalent to traditional 50W Halogen but the bulbs were €25 a pop :eek: I think these are the ones he spoke about

    You get what you pay for. However I am sure that they can be purchased for less, check the LED sticky. You could always install cheaper LED lamps in not so important areas, such as Greenlamp @ about €7 each. Reserve the expensive Philips lamps for the kitchen and sitting room.

    As he's the guy who originally fitted my 60 downlighters

    That was at a time when electricity cost far less per unit and LED lamps were not anything like as good as they are now.
    he's offering to fit however many of the new GU10 Philips LED bulbs I want, including a new bulb fitting for €20 a downlight all in i.e. including the bulb, fitting and labour on the basis that he keeps all the transformers he takes out which he can then use in small repair jobs he does etc.

    Sounds very fair to me.

    They look like cheap muck to me. No make stated is a bad sign. You might get lucky, read the LED sticky.

    I have Philips master led non dimmable and they produce great light,very similar to the expensive ones your sparks is suggesting,main difference are mine are 2700K and 4w whereas those are 6w 3000K. I have them in the kitchen,6 in total.They were €9 each a couple of years ago in Eurosales.They have a 15 year lifespan so the economics of switching to LED soon makes perfect sense. The box off them says equivalent to 35w halogen lamp but in reality I find them no different to the 50w's they replaced once you get used to the slightly different colour they are compared to a normal halogen.

    I would suggest getting a small number and trying them out in a room before you switch the whole house.

    Good advice.

    As above I got 4W dimmable Philips master for 8.65 euro from eurosales in oct 2012. Try giving them a call.

    You could change between 6 -10 in an hour so all in the price isn't to supply and fit isn't to bad.

    As you have so many it might be easier focussing on the most used ones first. The phase 2 could be the rest.

    Also the cluster LEDs don't look great.

    Thanks everyone,

    Going to go with the new 5.5W Philips 50W equivalents I linked to earlier in the main living area (combined kitchen, dining and lounge with a total of 22 downlighters in it) and try some of the highest reviewed generic/cheaper options in the halls /bathrooms etc where the quality of the light isn't so important.

    That's the current plan anyway.

    You've been very helpful. This is why i love using Boards, fantastic people.

    Cheers,

    Ben

    Your situation is almost identical to mine except I only had 15 downlights to swap out. I got the 8W dimmable Philips Master Leds from Eurosales at around €25 each to replace 50W low voltage downlights. Glad I didn't go for anything with less lumens. I did the swap out myself and the electrician who originally installed the 50W downlights bought back the 15 sets (transformers, bulbs and holders) from me at €5 a set. There's a big heatsink on the 8W, I don't know about the others, and new holders were needed.
