will night rate be worth it: any experiences

davgtrek

hi all. just trying to analyze elec costs to switch to night rate etc. standard house, oil heating with rads, 1 elec shower, tumble dryer / dishwasher/ wash mach. all lights in house are cfl. high grade 600l cylinder with 2.8kw emmersion. typical bill could be 150-200 euro. all appliances have up to 6hour delay button so getting them to switch on at night would be easily doable.

has anyone switched from standard to night rate and has there been a perceivable saving ?
have you got it to work for you.

no real risk as its free to get setup but its €190 to switch back.

thanks

Well I just checked the ESB rates and quoted as follows

Standard
2 months standing charge = €15.37
unit = 16.4 c

Night Saver
2 months standing = €21.11
day unit = 17.52c
Night unit = 8.67c

If that's the rate your on then €200-vat = €176.21-standing charge=€160.84 divided by the cost per unit gives 980 units.

As you can see, if you change over and use all power during the day it will actually cost you more.

To get the exact same bill on the night saver tariff using the exact same amount of power (just using some at night) you would need to use
791 units at daytime and 189 units at nighttime (same power consumption, same bill)

If you can transfer more than this amount to night then you are saving money, if you can't then its going to cost you money.

So tumble dryer / dishwasher/ wash mach can all be ran at night.
Shower, kettle, lights etc can't.

it's suitable where there's regular usage at nite (heat pumps,electric aga's,economy 7 water heating,storage heating) in addition to appliances.i don't know if the saving will be made otherwise

Surely it wouldn't be a good idea to run a tumble dryer while asleep in bed?

no i'm not advocating going to sleep with appliances running anyway .the conventional wisdom was always that there should be off-peak water heating or similar off-peak loads with nightsaver rather than trying to run appliances all-nite to make the saving

Why not? The noise?
If the noise doesn't bother you then yeah, do it. Maybe it's out in the shed.

No, not the noise.

I'm referring more the potential fire hazard. While extremely rare, they have been known to go on fire, where thermal cutouts fail or some such.

the drying would be better done first thing in the morning alrite
