Home Charge appoint - Future Prep

Gumbo

Guys, I am doing some works on the house in the coming months.
The works will involve new build walls etc in the area of the existing ESB meter box.

I don't have an EV now, but I know I will have in the future.

What can I do not while my sparks is on site that will make it easy to charge later?

Is there a cable or similar that can be wired up or am I missing the point here completely?

Get a 32A capable cable run from the distribution board to where the charge point would be.

Put that cable in some small ducting if possible. Irish electricians have this horrible habit of wiring whole houses without using cable ducts which means you have to rip up the walls to replace, upgrade or run new cabling.

My ESB meter is on the gable wall in my side entrance. So in reality it's only a foot or 2 run to where the charger would be in theory and all external work so maybe no need to do anything just yet?

Probably just make sure there is enough room in the box for the MCB

Not permissible under ETCI regs to my recollection (to mount anything in the meter box). The only exception was a single MCB feeding the consumer unit,,.
The cable would need to go to your consumer unit
WHat about lighting in the area where to plug in the charger?

I remember Cros saying you can take a feed direct from the meter ?

can you tell us again cros ? I'll need this soon because we're moving and the Meter is only a few meters where I need the charge point V having to take it from the consumer unit which would be a complete pain in the arse.

Accurate, I thought the OP was just a few meters from the consumer unit...reading fail..

When I got this particular house switched over to the nightsaver I requested one of the models of meter with a built-in isolation switch on the consumer side of the meter. Then fitted an intermediate IP68-rated panel between the existing consumer unit at the meter. All my high load stuff is coming off that panel and it has enough room to add three-phase if I decide to go that route. The three-phase would be kept within that intermediate panel and I have enough loads to it to balance things out a good bit.

I just want to be able to take the EVSE direct to the meter can I do this via this isolation switch ? put RCBO at what end ?

Can you post a pic of your meter please ?

Did you have a thread on this topic a few months ago? Something about PV being fed in also?

If so, sounds like you went for the install we were discussing - how'd it work out for you? Any hassle with intercepting the feed to the consumer unit?

Is there any cost or downside to going to nightsaver?

Obviously the night time electricity rates go down, but is there an increase in day time rates? (I'll have domestic appliances, like washing machine, dryer, dishwasher still going at daytime). Any difference in rates at weekends?

Is it ESB Networks I would need to ask or my electricty provider?

Roughly speaking..... day rate goes up 1c/kWh, night rate goes down by 8c/kWh and standing charge goes up €50/year.

If you have an EV it will pay to move to night rate pretty quickly (weeks, not months).


You ask your provider and they organise it with ESB Networks to give you a day/night meter. Costs nothing to get them to do that.

All the prices for day/night/standing charge is on your provider website but what I have detailed above will be relatively close to it.

MY day rate went down 1 cent.

Was that directed at me ?

I rang my provider (Panda) on Friday afternoon. They took my number, said they'd make an appointment with ESB Networks and they'd ring me back

Rang me back a few minutes later saying the appointment was for Monday (yesterday) between 9AM and 5PM, but that the ESB Networks engineer would ring up front to say when he was coming

ESB man never rang me, just rang the doorbell Monday morning and did the install in about 15 minutes

As you say, no charge. Will look up the impact on my rates this evening and report back here.

I pay 8 C Kwh night and 17 day on Bord Gais Level Pay.

unkel

Discounted rate 8.08c night / 16.65c day and standing charge per year €191.84 (15.47c and €157.76 on 24h meter). All amounts incl. VAT.

This means with an annual consumption of 5,300 kWh, you need to average 3 units per 24h on night rate to break even. I can easily enough do that without even having an EV, but there wouldn't be much in it

Looking forward to driving 1000 km on about a tenner of electricity though

KCross

Im with Airtricity.... 15.17c/7.51c inc Vat

unkel

Standing charge cheaper than mine too?

Up for renewal in a few months time. I always switch every year. Looks like my current provider is no longer the cheapest.

Depends on whether you have an urban or rural location..... i think your urban?

Standing Charge inc Vat
Urban Nightmeter: €194
Rural Nightmeter: €236

Indeed. Pretty much the same costs I have then. I think my renewal is coming up in June. Will do my yearly quick switch then.

Just checked my dual meter and I'm surprised to see I've used 6kWh on night and 15kWh on day since I got it installed 48h ago. The only thing I switched on late on purpose was the dishwasher (16 years old) once.

Oooh... thats probably a really bad dishwasher before the A rated ones came in.

That thing could be costing you a fortune!
But at least its down to half a fortune now!

A few years back I bought one of these things (not this exact one):
http://www.ebay.ie/itm/UK-Plug-in-Electricity-Energy-Meter-Watt-Voltage-Moniter-Analyzer-Power-Meter-/221857508844

Its good to figure out which appliances are the culprits. You sound like you like facts and figures you might find that it would "pay" you to buy a new dishwasher.

Did you by any chance have the immersion on during that time?

Anyone use an electric shower?

Do you leave any lights on overnight?

Your fridge would account for some of the consumption.

My average consumption for the house was 6.6 Kwh per day before the Leaf and 18.3 now after Two years of leafing.

So the Leaf is consuming a lot more energy and that's even with 50% of my commute being free, still, compared to even the most efficient , slowest , smallest manual dirt box diesel, it's a massive saving !

A good deal more of my leccy is used at night even working shift even when having to charge for half my work month on day rate when working nights. Speaking of, must go get some kip for tonight, I hate starting nights again !!!

No, no and no (only some 1W nightlights)

Fridge is very efficient and new, but it is very big (biggest kind of non-US fridge I could get)

There probably would have been half a dozen mobile devices charging, and all my a/v equipment would have been on stand by. Also one or more TVs would have been on between 11PM and midnight

Also I tend to go to bed late, so have powerful PC on, massive monitor, AV receiver, and lights

@KCross - yeah have one of those - bought it in Aldi years ago. Quite shocking the differences of some applicances in stand by mode consumption. Haven't tried it on the old Bosch dishwasher yet. Forgot to say I did run it in the very long cycle because it was very full with some greasy stuff in there. I guess that would account for 2kWh consumed or something like that

I'd say it will be a good bit more than 2kWh on the basis that its a 16yr old machine.

I think I calculated my 5yr old one at <1.5kWh on a non-eco wash cycle. Yours is likely to be much more than that. The older ones tended to have more water and hence more heating required. Check it and then do the math. It might be cheaper to change.

If a new one saves me 1kWh per cycle (at night rates) and I run it 4 times a week, it will take me well over 30 years to make back the €500 a new one costs

Thats assuming its only 1kWh!
It all depends on the figures.... how about if it is using 3-4kWh's and the new one only costs €300.. Im sure you can get a better deal than €500!

This one is only €289 and uses exactly 1kWh per cycle.

Payback is now about 6yrs. Thats a bit too long to be fair but it will still pay for itself and the new one will use less water too.... which might matter in the not too distant future!

I dont think we could be any further off topic so I'll stop!

Quick update: measured it last night and the normal cycle (65C) uses 1.47kWh in my 16 year old dishwasher, so it would take almost 40 years for a new "eco" Bosch €289 dishwasher to pay for itself

So that begs the question.... what used the 6kWh's?... you have something else hungry in the house as a few pilot lights shouldnt add much and a fridge will also be minimal.... are you growing plants in the attic?!

unkel

6kWh was for 48 hours. Also that time I ran the dishwasher on intensive cycle, so that might have been 2-3kWh. And my PC, with AV receiver and massive monitor would have been on for several hours per day on night rate, also one or more tvs, kettle might have been boiled for hot water bottles, night lights, lights in the morning for an hour in most of the house and chargers / appliances in stand-by mode. And a huge fridge / freezer. And Alexa and all the smart sockets

But yes, I must do some more checking to see are there any leccy munching culprits!
