Replacing an old Economy 7 heater with a modern one, will I save much on electric bills?

Yep, just bought some carpet slippers this morning. Half the price they were just 2 months ago.

I've a feeling you may regret that overnight charge this afternoon 

from 21c down to 16c then 18c
Quite reasonable though above my new SVR £.3.90 daily limit...
18:19 £4.79 -last test to find idea if overnight storage can last until 21:00 approx.
Today and Tomorrow I'll use some 9-15c settings.

thanks

Some DQ fun points.
.
I reverted to Heater System Resat as it has been quite varied heating results.
Last night into this morning provides genuine 21c from 05:10 util 08:15 before Setting Back to 9c until 15:15-19:00 21c

What I did Manage during Reset- I actually could set my Eco 7 times aka WM -This has never been programmed from 2 Electricians though It was 2nd Electrician that reccommended I check pre programmed Times after Wiring was checked and found to be correct.

Some essential Tips from Dimplex Hub+Mob App.

I'm using VM Fibre Internet -I Must connect Ethernet Cable from VM to DQ Hub, as DQ Hub only uses 2.4ghz Wifi and VM Extenders auto Switch between 2.4/5ghz resulting in Zero Usage Charts on DQ Control mob app.
Ethernet connection has 100% restored DQ Usage Charts.
That DQ 'Control' mob App- If and when altering Heating Schedule Times -Make sure the TimeZone is reselected and 'Switched' before new times can work.

I'm finding this confusing.  Your meter determines the E7 times which are set by your Distribution Network Operator.

You have both 24h and E7 switched supply circuits so you don't need to program the Quantum to shadow the E7 times, you only have to tell it when and how warm you want the room to be.

What's WM?

WM White Meter Tariff often confused by many as Eco 7.
I found re programming  times helpful from factory times only adjusted an hour or two.

But as Gerry1 says, the White Meter supply is itself switched at the meter; when it's live, you have cheap rate, when it's dead, you don't.

By directly programming the heater with your assumed cheap rate times, don't you run the risk of the heater charging on peak rate electricity when the WM supply is dead?

Excellent points 
The Factory reset preprogrammed times which DQ calls Eco 7 (My SP tariff are WM units -same idea)
I have slightly adjusted these Eco 7 times which shouldn't effect Day Rates once 08:30 stops Eco 7  Low Rates socket working.


@Gerry1
There was some doubt as to wether my Electricity is actually switching over as expected as I've had very few overnight heating for next morning, though my Mob App is 100% setup as are 'Home' Heating Zones.
I missed the 're select' Zone as I had been trying various times+temps via mob.

Hopefully it's setup now.

Sounds like you may have ended up with something that's neither fish nor fowl.

As the Quantum has both a 24h and a White Meter switched supply it simply doesn't need to be programmed with the cheap rate times, it should be ignoring them completely.

It's like setting up a Direct Debit to pay your council tax and then popping in to the council offices every month and paying cash over the counter.

Similarly, you'd be in no doubt whether and when the Quantum's switched supply was live if (as previously suggested) its fused spur had included a neon indicator.

Overnight stats continue to make me believe that my Eco 7 low rate Circuit is using GMT times as chart stops from 4 a.m. after I had chosen 5 a.m. end times.
Maybe I need to re check DQ DST daylight savings which I had chosen on power up and after recent reset.

As a rule traditional dumb meters (analogue or digital) have fixed clocks and don't adjust for BST (or for anything else).

I don't know if RTS switched meters do, or not; maybe Gerry1 has info on this?
