We have just moved into a new house where its all electric heating. We switched one of the electric heaters on in the living room around 7am this morning and switched off about 9am but the heater as still been quite warm all day even though its been fully switched off. Its as if the heater is still on without any power.

anyone know what could be wrong with it apart from broken.

That's what storage heaters do....store heat. Normally, they heat up overnight (on cheaper electricity) and give it out during the day.
If it's a storage heater, then it will still give out heat when switched off. Storage heaters should be left on all the time in the cold weather. You should be able to adjust the temperature you want them to work at, then they store the heat overnight and release it in the day time.
Ruddy 'ell!

You've just created energy from nothing, disproving the First Law of Thermodynamics and instantly putting all of the energy companies out of business!

Alternatively, it could simply be because it's been a very mild day, so the rate of transfer of heat from your storage heater to the surrounding air has been far slower than it would have been with a lower ambient temperature.
Sometimes they have a boost facility to add extra heat during the day at full price electricity. That is probably what you switched on and off.

However the main heat is stored overnight at cut price electricity, and it is probably that heat that you are now feeling.

The only odd thing with this explanation is why you felt the need to turn it on at 7am. Was the heater cold at the time?
...Chris, I think that somebody who switches a storage heater on at 7am and off at 9am, doesn't fully understand how they should normally be used.

No I dont understand how they work as ive only ever used gas heating in the past. Its all new to me.
Did you get an instruction manual for the heaters?

If not try googling for one.

You really do need to understand them to get the best out of them.

Switching on the daytime boost 9if it has one) is a very expensive way to heat.
fabemmy....have a read of this, it explains how to use them.

Fabemmy, I have storage heaters and am happy to explain.

You will have a seperate meter for them through which they draw power at certain times, mostly at night. That heats up the stones inside them and they keep warm, storing the heat for you to beneift from during the day. Economy 7 gives you 7 hours, economy 10, 10 hours.

Most likely the power was on to them over night and they have kept warm all day. They will power up again at 10pm unless you switch them off at the wall.

I'll just check the actual timings for yiu and come back.

Maydup, the times vary in different areas, to avoid too much of a surge hitting the power stations.
I see the timings vary from power company to power company and across the country. Who are you with?
The 'Economy 7' and 'Economy 10' times vary between electricity suppliers, Maydup.

Quote 1:
"Economy 10 times differ depending on where you live and which energy supplier you’re with. For example, there could be:
Three off-peak hours in the afternoon (e.g. 1pm – 4pm)
Two in the evening (e.g. 8pm – 10pm)
Five overnight (e.g. midnight – 5am)

Scottish customers are more likely to get:
Three hours in the afternoon (e.g. 1pm – 4pm)
Four in the evening (e.g. 8pm – midnight)
Three in the early morning.(e.g. 4am – 7am)

Some areas and Economy 10 electricity suppliers change these times when the clocks go back or forward – so your afternoon hours could be 2pm to 5pm during British Summer Time and 1pm to 4pm in the winter during Greenwich Mean Time. Other suppliers may not change the hours. Either way it could mean that for six months of the year the off-peak hours are less suitable for you"

Quote 2:
"Economy 7 times differ depending on where you live and which energy supplier you’re with. For example, the seven off-peak hours might be 11pm to 6am, 12 midnight to 7am, 1am to 8am or even 1.30am until 8.30am. You would need to check with your supplier.

The hours usually change when the clocks go back or forward – so your Economy 7 times could be 1.30am to 8.30am during British Summer Time and 12.30am to 7.30am in the winter during Greenwich Mean Time.

Occasionally a company will divide the seven hours into two or more periods, so that your electricity cost would alternate between the two rates during the night. Once again, it’s important to check with your supplier exactly when their off-peak hours are, to make sure you don’t use appliances during peak times by mistake"

As others have indicated, Fabemmy, storage heaters are designed to run from a separate electricity meter, so that you only have them taking power at the cheap times of day or night. Rather than giving out all their heat straight away, they store it up and gradually release it throughout the day. In practice, they're extremely useful for people who are at home most of the day (such as many pensioners) but possibly less so for people who are out at work all day (as they're not at home when their heaters, that have stored up heat overnight, are then ready to heat their rooms).

We are with SSE.
From the SSE website:
"The ‘off peak’ hours for Economy 7 vary depending on where you live, but generally they run between 11:30pm and 6:30am during the winter, and 12:30am to 7:30am during the summer"

and
"The ‘off peak’ hours for Economy 10 vary depending on where you live, but as a guide the low rate runs for five hours overnight, three hours in the early afternoon and two further hours in the late evening"

Contact SSE to find out which tariff you're on (and to check the 'off-peak' times):

Great, well done Buenchico.

So fabemmy, your heaters will heat up during those times. You will get used to it, but you do have to decide now whether you want any heat tomorrow. If not switch them off at the wall.

Remember that all of your electricity is much cheaper during those hours. So get a timer on your washing machine and run it at night. charge up your gadets overnight too.
Wish that were the case in my home Maydup - my heaters are on their own circuit and meter.


My large Heater in the lounge can take 36 hours to cool after a full heat up.

Thank you for the help. I understand them a lot more now
Last Economy 7 house I lived in had a meter which was fitted with a radio-controlled switch, which made a loud 'tok' noise at switchover time. One time, I heard this go off at 3am, because I had insomnia at the time. When I made enquiries (Southern Electric, at the time) the reaction was a sort of "yes, that was us doing that; sorry", like I'd caught them in the act.

I would encourage all those with indoor CCTV and Economy 7 to check their night recordings for the sound of the switch operating or, if they are mounted close enough together to fit in shot, have it monitor both meter readings overnight and then we'd have proof of any unorthodox practices.


Our heaters are on a seperate meter too Mamya, but both meters are charged at the low rate during the night. if you're on economy 7 or 10 yours will be too.

Make the most of the night rates as the day rates are higher than the standard tariffs.

I'm not but agree many can make use of it, though the chap upstairs doing his laundry at 3am does keep me awake.
