I was originally going to put in the fischer heater, but after reading through all the posts on here decided to leave it.

Oh my god I'm so glad to hear that thread is doing some good!

Getting the Fischer heaters would have been a big mistake for you.

I take it the quantum will pay for itself over time compared with the Duo

-

I should just keep it the way and not bother with another element in the top bit?

- a pointless exercise in futility, you have no water controller setup
- if you paid the £80 & fitting & new stats and lements, its unlikely you would benefit because its unlikely you would ever use or benefit from this facility Hortsmann & fitting costs]

should I put more on it (one of those red covers I see in Wickes etc

- always a good idea, get at least 4 or preferably a 5 petal jacket
- make sure you get the correct size for your cylinder, preferably with a bit of overlap
- make sure you can fit it inside an airing cupboard all around the back of the cylinder
- do not cover the stats or the electric cabling

My suggestion on installing 2-DUO's ~v~ 1-Quantum was made to indicate to you [MSE rule] that for the same money spend you could have 30% more total storage of cheaper night rate heat and 2 radiative directions into a room, its a comfort thing. There's nothing wrong with choosing to go with the Quantum, even as a 'stand alone' unit.

Thanks. Great advice about the water tank. I'l insulate and leave as is (bottom element only-heating on Q7).
I'll go for the big Dimplex Quantum heater also. Whilst 2 duos may give more heat for same price the installation costs would be too high to justify this and as the old storage heater heated the place fine for the last 25 years Im sure the new Quantum replacement will do a better job than before at a (hopefully) cheaper cost per annum.
thanks for all your help.

I will - however after phoning several places they said the 1.5 might be too big for the room size! I presume the 1.5 will cost more to run also (even if the temp is set the same)?
Now confused even more!

I would still get the biggest. It will not cost more to run (It'll take whatever charge is required, just as a smaller one would), it'll just have more capacity when it might be needed.

Always best to store as much of the cheap heat as you can, so you can avoid topping up with the expensive heat.

- twice the size would not be too big, its a bank account [of cheap stored heat], you can half fill - quarter fill or right to the brim
- even with a properly estimated size you are always going to have a dozen or so days per annum where supplementary heat is needed
- the trick I remind you, is to have enough stored cheap heat without the need for the damper to be opened in a cold snap - ever !

Hi. Reading this thread has been really helpful as I too want to replace old storage heaters in my living room and have been contemplating Dimplex XLS, Duo or Quantum plus an additional panel heater. The room is about 16sqm with 2.6m ceiling, cold sash windows and currently has one (broken) storage heater under the window and space for a second heater on an internal wall but with no existing wiring for E7 there. I was thinking of getting XLS24n (3.4kw) under the window plus a small panel heater in the other spot. OR I could get 2x Duo's but don't know how hard/pricey it is to add a new E7 connection. Then I saw the Quantums but am confused why they appear to a) only have max 1.5kw output (see table below from Dimplex website) and b) why my room would need 2.55-3.4kw for an XLS heater but only 2kw for a Quantum (see table poste earlier in thread). What do you think would be the best solution to get heat day and evening at the best price?

Quick update on my Quantum 150 for anyone interested....

Managed to replace it myself. The old one's bricks disintegrated when taken out! The new bricks in the Quantum look better quality though. Had to get an electrician to fit the 13amp connection though, which involved taking a cable from a nearby power socket, which caused a hole in wall, so make sure you have a socket which can be reached from your heater without too much hassle (wire goes behind wall). But it was easy enough to connect to the old E7 wiring (you need your own wire as its not supplied) and attach to wall (fixings provided-you need a drill depending on wall) and then put the bricks in yourself. This would save getting an 'expert' in to do it (apart from the 13amp connection which needs someone who knows what they're doing) and save a few £.

As for the heater itself- it looks smart (it covers the existing feet holes/marks from your old heater) when installed and the controls are very good also. Heat wise I cant say I notice any difference from my old one and despite setting the temp on the heater it never matches (or comes close to) the thermometer I sit next to it. The built in fan heater is ok I suppose but defeats the purpose of having a storage heater as it goes on all the time and is costing a small fortune! In hindsight I would've been better getting a cheaper storage heater and a separate panel or fan heater for heating up during the day or in evenings.
Not really impressed with the heat- I have it at the highest setting (26 degrees) and room never really heats up unless you run the fan heater for a few hours, which defeats the purpose.

All in all a well designed heater but does not justify the extra costs IMO and I dont see it saving me any money on electricity- quite the opposite in fact !

Thanks to brotherjackson for the thought through 'hands on' update ...................

Assuming an existing E7 setup anyone can do a DIY install of Quantum or the preferably the DUO with a non-fan assisted 13a microwire radiant element. A fan in my opinion should be on a ceiling and used in the summer to keep cool - I have no use for a fan heater - any fan heater. The actual install is a simple like for like swap of wiring, so don't let a sparky baffle you with science. Any radiator of any kind should never be on an outside wall and never under a window.

TeacupFairy, the DUO already has what you call """an additional panel heater""" built into it, so you do not need to buy an extra panel heater or make wall space available to hang it on. What you call """new E7 connection""" is not needed the old connection can be reused, you will however need a new 13a connection close to the new DUO heater. BTW if you have a fireplace block it with a chimney balloon - its a massive source of heat loss.

NOTE : I have long defended the excellent Quantum as a whole, but not as a part system. You might install just two storage heaters this year, two more next, then in the third year put in the 16a water part and the multi-zone controller. If its not your intention to go all the whole hog Quantum then just go DUO.
