I just arrived in Ireland, so storage heaters are new to me. I found a user guide online, but I still have some questions.
For example, in summer I only need hot water for doing the dishes, not for the heating (the electric shower heats water by itself). Isn't is a massive waste of (off-peak) electricity to heat almost the whole night for at most 7 litres of hot water for the dishes?
Second, if I heat (off-peak) anyway, why not switch on the heater in the living room to use the heat at least, even if it's only a bit chilly inside? I mean, I've paid for the electricity already, and there's no way I can spend all that heat doing the dishes. The heat surplus will otherwise simply disappear, right?
Does anyone know what exactly the 1 Hour Boost means? Does it produce the same amount of heat in less time, or simply less heat? Can I use it at off-peak hours too?
Finally, what if the heat runs out during a very cold day? Does it then heat during the day? I'm asking because there is just OFF-PEAK and OFF on the control panel.
Immersion, not your storage heating for this.
It just switches your system back on for another hour, this is when you don't use your timer to set times for on and off, you just hit the boost button and it turns on.
Storage heating is the worst ever!! Sorry.
Thanks. So how should I activate this "immersion". All I have is the control panel as shown in the online manual. I don't see any "immersion" switch anywhere...
I need to pull a cord to get hot water for the shower, but I guess it's not connected to the kitchen.
First of all do you know what an immersion is?
Well it is a heating element in your hot water cylinder, basically like the heating element in your kettle but on a much larger scale.
Your storage heating are thermal blocks, you could say like building blocks!! inside what looks like a large radiator. These are also heated up with heating elements like your kettle but they are not connected in anyway to your water supply.
Standard storage heating control panels only control your storage heating which includes the boost button.
Usually beside them is the immersion switch or else it could be in you hot press were your hot water cylinder is.
Have a look in your hot press and see if you can find anything.
Sorry, also immersion is new for me.
I looked at the hot water cylinder, but no switch.
There is a small black tank on top. It refills whenever I use water (even when flushing the toilet). I guess it contains cold water only.
Small black tank for water sitting above your hot water cylinder, have a look at the top of the cylinder and see if there is any small cylindrical device, usually white plastic, with an electrical cable coming out.
If not there is no more I can do for you.
The control panel you have linked to is your immersion switch. It has nothing to do with the storage heaters. Here is a thread which might help you out with the actual heaters. You should have two elements on your cylinder. One is on the bottom and is controlled with the timer (off and timed switch) side of the control panel and another on the top of which is controlled with the boost switch. The idea is that the bottom element or immersion will come on during off peak hours to heat the entire tank and the top element can be switched on at any time to heat the top of the tank for a small amount of water. You will notice that the boost switch is also a timer with a max setting of 60 minutes. So basically if you just wanna wash dishes you might as well stick to the boost function every day. Trial and error will tell you how long to turn it on for.
I am a “newbie “ to storage heaters and have found all postings very helpful. I have the basic Creda heaters with 2 dials .
Still puzzled with this Devireg 710-2 Thingy in the fuse box. What exactly is the dial next to the red flashing light for with
+4 +2 0 -2 -4 next to it .Even on the Devireg web site this is not clearly explained.
Quick guide to them:
Storage heaters get hot during the night. There is a sealed clock near your electricity meter that controls the supply to the heaters. Most of the time it's 12pm to 8am summer time and 11pm to 7am winter time.
If you're on a "heat only" tariff, the clock controls your heating and doesn't interfere with other appliances. More likely you're on a Nightsaver tariff, where the clock turns on your heaters and changes your electricity supply over to the night tariff.
Start off with the Input or Charge control about half way, and turn on the switch on the wall. You should see the neon light on the switch turn on at around midnight, and switch off after 7am in the morning.
The Output or Boost control will let you control how fast the heat gets out. Start with it very low to make sure the stored heat lasts the whole day, and turn it up in the evening when you get home if you need more heat.
Your storage heaters may also have a separate fan or convector heater that uses normal electricity. It's best to avoid using this if possible. Your heater may be a fan-assisted storage heater which is a bit different, but there are very few of them in Ireland.
The water heater is totally separate. The tank will be heated automatically if the timer is set, and is cheaper than using the boost control.

The Devireg units are fitted in some installations, I've never used one personally though.
Instead of having to adjust the Input control to suit the weather, the Devireg box varies the amount of time that the heating is on. When the storage heating clock turns on (between 11pm/12am), the Devireg will calculate the number of hours that the storage heaters need to be charged for to suit the outdoor temperature. On warmer days it'll charge them for fewer hours, on colder days they will charge for longer. The charging is delayed, so the Devireg will turn the heaters on at the correct time during the night.
It's generally best to set the Input controls on the individual heaters to max if you've a Devireg. In Ireland the "Day" dial (if there is one) is not normally used. If it's too cold the next day turn the dial on the devireg to higher numbers, if it's too warm turn it to the lower numbers. Once you've that set, it will auto-adjust to the changing weather conditions.
The Devireg can be a bit hard understand, but if set up correctly I hear they work very well. Hope that helps.
Very much appreciated.Thank you.
I used to get an email if a new reply was posted to this thread, so when I got nothing I thought the topic was dead. Therefore I missed some of the replies, sorry.
Some white cables come out of the big tank, but no small cylindrical device. The upper half of the small black tank is out of sight/reach, so I doubt there's a switch up there.
Maybe this pictures will clear things up... (I haven't thrown away the previous tenant's stuff yet)
Thanks! That makes perfect sense. Just wondering if, after having done the dishes, I can use the "remainder" of the heat (stored in the small black tank) for heating the living room?
With regard to controls, I have this control panel close to the tanks
Then this in the corridor
and this in the living room
I have a devireg 710-2 installed on the Night Storage Heaters. The kit consists of small sensor box is fitted to a north wall. This senses the outside temperature which is fed through a signal wire to a controller on your Consumer Unit. This regulates the almount of electricity fed to your storage heaters according to external temperature. Set the thermostat input on each individual heater at High/Max.
The unit automatically senses when your Night Tariff switches on and off (say 11pm to 8am).
On mild nights your storage heating may not switch on until 7am and the heaters do not become very hot, but your house is comfortable because it's not cold outside. On Bitter cold nights the Storage heating charge will begin at 11pm and charge all night to ensure your Heaters are at full strength. There are tweaking buttons on the controller to adjust the level of charge to your requirements (depending on your wiring set up, to also provide a small boost to the heaters mid day, although I think this is not available in ROI, only in the UK)
It is very useful, as the system is "set and forget" and it adjusts your electricity heating inputs according to weather conditions, so you don't have to be fiddling every day with your heating controls. I reckon It saved Me about €100 per year. It cost €100 to buy in 2005, so it has paid for itself.
The Day control will do nothing here I've since found out. The controller will figure out the night period. In the UK there are a few tariffs where you're given a "top up" during the day time, typically in the late afternoon. The controller will watch for a shorter time like that and let you adjust the charge time with the Day knob.
