energy monitors - advice

Are you sure some of you posters aren't confusing your fridge with your electric fire? A £109/yr saving running a new fridge? How long did you have the energy monitor connected to the old fridge and the new one? A fridge is one of those appliances that probably needs to be plugged into a monitor continuously for at least a week to get even a chance of an accurate reading. Just a thought...

^ The last time I checked mine I could theoretically save £12 per year.

No confusion. Old inefficient 20 year old fridge freezer out, and shiny new A+ rated one in. Average household usage before was 85kwh per week, average after was, and still is, 70kwh per week. Estimated payback for me was in just under 3 years. Meter readings taken constantly over time (3 years), and the only change to supply usage was replacement of fridge freezer. (I even have a little graph to show it, sad I know, but a 'money saving saddo').

Incidentally, studies have been carried out using your own methodology comparing old fridges with A+ EST recommended models, which show savings of £101 per year, so the £109 figure is in the right area.

May not apply in all cases but those sort of savings should not be sneered at.

Now I'm definitely confused. Now we seem to have progressed to a fridge/freezer and not a fridge?

Yes I see you are. Istar referred to a fridge freezer as did I. He claims savings of £109, and I claim similar savings. You referred to 'posters' meaning, I presume, me and Istar. I think the 3 of us would accept that a fridge would not produce those sort of savings.

I had my old fridge freezer connected to a plug in monitor for 2 weeks, it averaged 2kWh/day over that period. I would save that much, but my electric is also expensive due to Pre-pay/Std Tarrif etc.

The new fridge freezer is bigger, and uses about 400W/day.

I did rush my figures earlier in the thread (more like £80 saving), but I full expect it to pay for itself in 2/2.5 years.

Anyway, just because it works for me and Dave Save doesn't mean it will for everybody. We both probably had very inefficient appliances.

This is why I said before that if your fridge/freezer is taking a lot of power, its probably knackered because these devices generally don't use much.

Sorry Millicent, I expect that is my fault.

It's an old family habit of just calling a fridge freezer 'the fridge' that I have failed to drop.

I can't comment on a fridge alone, all my information is based on replacing and old (no idea age as it was in the flat when I took it over) Hotpoint fridge freezer, with a brand new Indesit A+ rated model.

Anybody thinking of replacing this type of appliance is advised to do as I did. Connect the device to a plug monitor for at least two weeks, and compare to the consumption of the model you are looking at. See how long it will take to pay itself off, and decide if you are happy to proceed.

I don't want people to think that just replacing old for new will make them a massive saving.;)
