I fitted a Dimplex Quantum heater!

You still have to set the programme at least by midnight of the day before, so the heater knows how much charge to take. You can use it without doing so, but its likely that it will run out of charge (as it didn't know you were planning to use the heat the next day). There is an independent heating element 'boost' function on the heater but using this sort of defeats the object of the storage heater.

However, what you do is set the programme (up to 4 periods per day) and the room temperature you want to achieve. The heater will then take the appropriate charge depending on the amount used the day before and the ambient temp. So you really can set it and leave it and the heater will do the rest.

So if you set it for 21 degrees for a week and the temperature fluctuated markedly during that period, the heater would calculate how much charge to take / not take depending on your usage the day before and the temperature. So effectively like setting the thermostat on your gas central heating system, between x and y time, please maintain 21 degrees, the heater then does the rest. In theory if the ambient temp rises above 21 degrees then the heater will not take a charge (as it doesn't need to), however it might take a small amount, just in case the temp drops and you need it. Dimplex do however recommend that you turn them off at the switches during the summer to prevent this small charge being taken.

Hope that makes sense

you say that You still have to set the programme at least by midnight of the day before? I have Total Heating Total Control and it boost 3 times a day from (6.30am-8am, 11.00am-3.00pm and 8.00pm-8.30pm.) so do I need to change my meter so that it will ONLY boosts for a continues 8 HOURS.

I thought a quick update was in order.

So now 2 quantum heaters up and running (one QM100 and one QM150). Both are working well. The smaller one upstairs raises the temperature in the study to desired level in about an hour. There is some small vibration noise on the heater fan which comes and goes as the heater turns itself off and on. Not a big deal but might need to get it looked at if it continues.

The heater in the living room / kitchen took a little more tinkering with to get to work effectively. I was finding that it was not raising the room the desired temperature (at 6pm in the evening to 8.30pm) as quick as I would have liked. After some advice from Dimplex (who have been pretty helpful) they advised that the room at 25m squared is towards the large size for a single heater. So I have raised the thermostat on the heater to 23 degrees and this seems to have made quite a big difference. The heater now takes more charge and the room is much warmer (settles at about 20 degrees).

Also a point to note, there is lots of functionality in the heater that is not covered in the operting manual, things like extra charge manually, setting the temp defaults etc etc.

So in conclusion the heaters are doing what they were supposed to do. They provide my economy 7 system with a way to let out heat in the evenings when it would be expensive to run to underfloor heating. I can confirm that the heater stores the heat very well thorugh out the day. There is some 'leakage' from the heater but actually that works pretty well for me as it stops the temperture of the living room dropping too much even when the heater is off.

I was concerned at one point that the underfloor heating would interfere with the heater thermostats but it doesn't seem to be. I have the underfloor on from 04.30 to 06.30, run the quantum in the study during the day, and then run the quantum in the living room in the evenings. As the quantum is doing is calculation in the evening the underfloor seems to have no effect.

I haven't done any detailed comparisons on electricity costs as yet, but on a quick and dirty assessment I think I'm currenrly using upwards of 75% of my E7 electic on the night rate which is pretty good.

Will try and post some links to pictures soon.

I have had 3 quantum heaters installed in my house 1 QM125 in the living room , 1 QM100 in the kitchen and another QM125 in the lobby / stairs.

compared to the older Dimplex CXLS range which I had previous the quantum seem to give you more flexible control of the heating input and output.

I have had them fitted on the 3/11/13, took a meter reading so I can see what savings if any on electricity costs.

Cool, I'll be interested to hear the results.

5 weeks on with new heaters average usage is 39.4 units a day for heating and hot water. say that if I have the heating on for 180/365 days possible usage is estimated at 7092 units or if on for 210/365 days usage estimated at 8274 plus for the rest of the year say about another 600 for hot water my heating usage for last year was 12400 units so I am looking at about a saving of 3500 units.

Both my quantums seem to be running really well. The only slight issue is that in order to maintain 21degreesC in the lounge in the evening (17.00 to 20.30) I need to set to heater to 23degrees. This means it takes more of a charge, blow hotter, but with this slight alteration is working great.

The main advantage is that I'm now using 85% of my electricity on the E7 night rate :-). I don't have any comparisons with previous (as I only moved in in the summer). But I estimate from meter readings that I'm using about £70 a month in elec in the winter and about £25 in the summer, which is pretty good.

Still using the underfloor heating for a couple of hours in the early morning, before the night rate clicks off at 07.30.

Will look at getting this pictures sorted out asap.

I live in a 1 Bedroom flat,and I have had one installed for 3 months. Seems cheaper than the original storage heater, but time will tell. The best thing about them is heat all day and the evening.My old storage heater was to hot early morning and then by 4-00pm was virtually cold,I have mine set on an "all day setting" and never had the dial above 19degrees.So great to have a constant heat all day and evening, it was well worth the cost about £850-00, and only need the one it gives out enough heat to warm the whole flat. Worth every penny!!!
