Fischer Storage Heaters

A question about : Fischer Storage Heaters

Fischer Future Heat has an adjudication against it for a previous promotional campaign. See the ASA Adjudication

Does anyone have any experience of Fischer Storage Heaters? (website is fischer-futureheat.co.uk/fischer-storage-heaters.php They claim these heaters are 40-50% cheaper to run than old night storage systems.

Best answers:

• any electric heater is 100% efficient [text deleted by MSE Forum Team].
  they seem to be ` modern` storage heaters with thermostats and timers - shut the damper down on minimum boost when not needed and open when it is BUT they also seem (because of mentioning solar pv) also be useable with day rate electric as well.
• Heat propagates in only three ways: convection, conduction and radiation. This material is an insulator [ pumice is one kind of fireclay called Chamotte ] often used in kiln's, for me I don't believe in the assertion that it is an insulator. I certainly don't go with the equal assertion that it saves 50-60% more spend than the conventional clay type heat banks used in standard E7 heaters.
  It's fair to say that if the characteristics of chamotte were those of an ' megga ' insulator then one very big saving could be made with E7, that of leakage.. .. .. Cheap night time input not leaked. Daytime while people were at work not leaked. Oh but hang on if they don't leak and are so efficient the room would be cold - wouldn't it ?
  Look .. .. the design of the heating element buried within the actual chamotte core means it reaches temp quicker, but well you .. .. know, you are in bed asleep at the time so what difference if it heats up quicker. I haven't looked at this since last xmas maybe the tech has moved - I'll do a gooooogly job tomorrow in case its improved.
• I'm reserving judgement until the OP returns with the price. AFAIAA, not readily available anywhere online, but I speculate that the OP might know, or know a man who does.
  On a specific technical issue the output of a modern "UK traditional" storage radiator is "dampered" when charging and when hot, as a mitigation against early heat loss, a feature which cannot be present in the "Fischer" as it is designed to be 50% energised during day-rate times and specifically makes a feature of "radiant" output.
  Nevertheless I welcome "imaginative" design approaches to improving off-peak heating as a method. The brochure is certainly "creative", but not technically informative. Perhaps that is the "imaginative" feature.
• I have used the Fischer heaters for the past year. When they refer to 40% reduction in energy input it is because the heat distributed from the heater into the room is more efficient. To prove that point, their thermostatic control is wall mounted in the room away from the radiator and it controls the room temperature very well. Unlike my old radiator which had a control on the heater, the Fischer heater is proving a better source of heat in my living room, keeping me warm especially in the evenings, at no extra cost. It also makes use of Economy 7 at night thereby making it cheaper to run. As I'm using less units now, even though some of them are at a higher rate in the day, it still is cheaper to run than my old storage heaters. As far as heating the room more efficently, I can say they work out more economical and better comfort than my old night storage heaters. I am very satisfied with them. So I am totally convinced that the distribution of the heat from the heater into the room is more important than simply the amount of heat you generate at the radiator. It makes complete sense
• Hi, Sorry to hijack this thread but I felt some clarification is needed.
  The heaters are in fact Radiators in that they radiate heat.
  If you hold your hand 10 cm from the front of the heater surely you can feel the heat being radiated?
  The ROOM though is being heated through CONVECTION as the air being drawn up is heated by RADIATION and then rises to circulate in the room.
  Most modern radiators also use this system.
  With Solar panels the heaters can store the heat during the day cheaply and release at night when most people are less active.

  Our low input storage heaters can reduce the energy intake by 50%, compared to the old night storage heaters

  Your defence of their product as a user is fine with me, but its based on the same drivel they post - you read - you then reassert with no supporting evidence whatsoever. BTW I assume from the figure [s] of 45/50% split you are retired and at home all day with a room whole house temp of 20C. If your not in the house on an all day basis there is something wrong with your E7 usage.
