You have a point. However, I was able to compare the two side by side briefly while the kitchen was being remodelled. Without a comparison, I can't see how one could say whether there is a drying effect or not. I have foudn that agas dry food LESS than fan ovens.

You can't say that something is or isn't the best for other people, because their criteria are almost certainly different. If you want it for "lifestyle" reasons then of course logic and cost is irrelevant. If you want to buy a cooker then both price and performance are usually important factors. Of course. An even more important factor than price is value. If somebody perceives enough value in something and has the means to pay, then the price is irrelevant. If they don't perceive value or don't have the means to pay for it then they don't buy it - simple as that. Performance is also a very subjective term and completely dependent on the factors that are important to the buyer/user of a product. Again, you can't assume that everyone's criteria are the same as yours. -- ..andy |

On Sun, 15 Jan 2006 20:39:20 +0000, Andy Hall material, your nose has been scoured by the sand to bare bone. I see no reason for the risk to be any greater with an Aga than any other form of cooker, if one is stupid enough to do that. You may see no reason for it but it is. Firstly because it is much easier for things to catch fire, This is completelt untrue. I have had serious fires regularly with gas, a couple of fat fires with electric, never had a single fire with an aga. The plate temeperature is below the flash point of anything bar possibly alcohol or gasoline. There is no way that anythung combustible can get to the burner - unlike gas hobs, ahich are bloody dangerious, and its easy enough to catch a sleeve alight with them I suspect that when your stupid girlfriend/ex wife who had an aga, dumped you for being a stuck up prig, you took against her wellington boots as well? |

But Peter Parry in the vicinity of an aga blows so much hot air - mainly out of his aree - and is always opening the doors to show how crap they are at cooking, and to ensure hat teh food isn;t cooked yert, that he manages to dry the food to a leathery wasteland. |

Where does the moisture from the food in the oven go? It certainly doesn't condense on the hot surfaces of the device :-). I can only tell you what I observed. In terms of mechanisms, the two that seem obvious are a) that the fan oven is not a closed system and b) that there is an effect from blowing hot air over the contents. Air at higher temperatures has considerably more water carrying capacity than it does at lower temperatures. These are only suggestions of possibilities. The observations were from side by side comparisons of doing the same things. Its why meringues can cook nicely in a fan blown oven. Although they are best done in the aga bottom oven over a period of several hours..drying is what you want in this case. It takes a LONG time to dry stuff in an aga. Mind you, the lack of whirring noises and red lights all over it may allow you to forget food is actually IN there. I do admit to scraping out mummified baked potaties several days after they had been installed. Even an aga won't keepo things moist for EVER, |

wrote: Come on Andy, The flue of an Aga has a draught break which entrains lots of cool air so any temperature after such flu break is NOT an indicator of efficiency I used to laugh when I came across test point holes drilled after flue breaks, usually with service record cards dutifully filled in with combustion analyser results taken straight out of the manual but quite obviously not the readings from the point :-( I see your point, but was not trying to suggest a scientific measurement. In fact, the cast iron vertical flue after the flue break is relatively hot (I may measure it later if I have time and can find the IR meter or thermocouple probe); however at the point where the flue enters the loft (some metres away), it is considerably cooler. This represents heat released within the fabric of the house. If the cooker were a balanced or power flue type, I agree that that would be a different matter. -- ..andy |

Don't think I've ever heard of a quality restaurant (or a crap one, even) using Agas or Rayburns to cook for their customers.. presumably they use inferior cookers to cook their superior food.. LOL. No, they cook food fast in restaurants, and they require massive volumes of cookers. They can have the luxury of a cooker for every dish they do more or less. Agas are not space efficient either - eye level ovens and gas hobs are the way to go in a busy commercial kitchen. Its is not customary to present the customer with fresh baked lasagne either - like as not is is prepacked and microwaved up for the plate..or was made yesterday. Agas are about good HOME cooking, not good commercial cooking. One aga can priduce a superb nmeal for 6-8 people. It can't produce an endless stream of fast food for 10-0 cutsomers. It's not designed to either. You won't find many homes with planer thicknessers either, or many joinery shops without one... |

That plate will just about sustain as simmer indefinitely..but if it doesn't then use the hot one again for the last hour or so.

Because most people have to buy things and both cost and performance are factors. What actually matters is value to the buyer and ability to pay rather than cost, and performance is a subjective thing in the context of a cooker. When the performance is mediocre and both the purchase cost and running cost astronomic there is no sense in buying one unless it is for other intangible reasons. You are describing the performance as mediochre based on your experiences of an old model and whatever criteria you subjectively apply. I completely disagree, based on my criteria and experience of a more recent product. It is not legitimate to make a blanket statement suggesting mediochre performance as you have done, since that is limited to your criteria only. Running costs are not astronomic. I already gave you the figures that I get, and do not regard those as astronomic. Again, this depends on your scale of values. I could gather firewood for free and cook on that, and argue that anything where I have to pay for the energy is astronomic. It's a relative term. GBP 9,600 for a cooker which then costs a further GBP500 a year to run simply isn't worthwhile when set against its mediocre performance. 1) At the measured rate of 700W, at a gas price of 2p a unit, that adds up to around £120. Yours appears to be the only Aga in the world to achieve this though. Every other Aga manages more like 1000W standing load and this increases up to 5,000W when cooking. How many modern gas models have you measured at 1000W? I can only tell you what I measured on mine, 700W quiescent. Given that situation, it would be rather difficult fo ryou to assert that mine is the only one that achieves those figures. "The running costs of these cookers is about £400-500 per annum" (Aga salesman). From the figures Aga quote a 4 oven gas Aga uses 527kw/hr a week or 27.4 Megawatt/hrs per year. At present gas prices that is an annual bill of GBP 540 - GBP 600 per year depending upon supplier. If you read *all* of the data sheet you would see that the word "typical" is used. They don't say what "typical" means or how they measure it. -- ..andy |

But where you are p*ing into the wind is in suggesting that they are in any way economical or practical. Don't let that spoil your enjoyment. Steam traction engines attract enthusiasts who spend many harmless hours having innocent fun with them but nobody suggests that they are a practical alternative to a modern vehicle. I don't see it in that way. Essentially, it's an energy store that I can heat cheaply and which adds to the space heating. The cooking is effectively free. In terms of practicality, again no real problems by any way of measuring that I can think of. For example, if anything, I need to spend less time standing at the Aga than I did at the hob. Could be wrong here though - any minute now some bearded old chaps in boiler suits could be angrily stabbing at their laptops with oily fingers! :-) cheers Jacob PS Come to think when I had a solid fuel Rayburn a boiler suit was an essential accessory - do they come with the kit if you buy a new one? Interesting point. You do get a pack of cleaning materials and a brush though :-) Solid fuel is almost impossible to use and a hugely dirty and labour intensive affair. I hpope I never see a coal fired anything ever again. I've cooked on two coal fired agas, and had to manage a coal ffred central heating system. and they are voracious consumer of filthy coal, and require twice daily servicing to get the new stuff in and the old stuff out. Woer betide you if you get it wrong - they are impssoble to control temperature wise, and if they go out, require at least an hour to get going, and about 3-4 to be up to whatever temperature they decide to be at. If the temp drops because te coal is running low, you have two choces. Let them get cold, or add caol, when they cool down even faster. To actually get a coal fired appliance working properly, requires a full time fireman. One of the major reasons, apart from the high maintenance, that steam engines vanished so rapidly. In the 50's when coal was cheap and husewives were HOUSE wives, and oil was something you saw other pople putting on the axles of steam locmotives, the daily round of lighting the coal fired appliances after de -ashing and de clinkering was, simply, as good as it got. Hby got up and befoire dersssing would put te kettle on take out the ash and clinker and add a shot of coal...then go to work... Once the aga was up to tempreature, you could make a cup of tea before boilig up the solied nappies in a coffer on it, and spending a merry afternoon with a hand mangle and clothes line. Another quick shot of coal and then down the shops for todays vegetables and bread and milk...walking carrying your string bag, or on a bicycle...then a quick tea and cakes to replace the lost calories before lighting the open fire for the evening, revving up the back boiler so that one bath might be feasible (who's having a bath tonight?) and cooking from todays fresh ingredients everyones dinner... This was before womens lib dears, when women actually WORKED HARD. And so did men, because if you didn't, you ended up cold, miserable and hungry pretty damned quick. No even I will not sing the praises of coal fired Agas. Better than nothing in the days when central heating was a rarity, but a last resort only these days. |

As a consequence, the CH boiler is running at a lower output than it otherwise would. In terms of the efficiency of use for space heating, I doubt whether there is much of a difference in terms of what goes out of the flue for either heat source. Hi, True, but if the Aga isn't room sealed then the ventilation requirements will be fairly genereous. Not really. Only in summer do you need to cool the place down, and I turn mine off. The air required for the burner is actually less than that specified for a gas hob, and the ventilation requirements to extract the combustion products are far more onerous. Agas end most of the cooking smells up the chimney too. No need for extractor fans. And the efflux temperature on an aga pipe is well below that of my newish oil CH boiler. So its apaprent its a better cinverter to low garde heat than that is. Condensing boilers would be similar I suspect,. however. If you were to encase teh aga in a small room and allow it to get insufferably hot, it most likely would use less fuel as well. cheers, Pete. |

They can be left on all year round, consuming 1/2 a bucket of coal a day and you don't need another cooker at all unless you can't handle the coal or don't make the Holy Ritual of the Riddle every day.

I completely disagree, based on my criteria and experience of a more recent product. More recent? The damn thing was last updated about twenty years ago. It still uses the same mechanical thermostat control it did in 1970. Running costs are not astronomic. I already gave you the figures that I get, and do not regard those as astronomic. You might not, even on your figures others might feel differently. However you have singularly failed to explain why your figures are so much at variance with the manufacturers ones.

How many modern gas models have you measured at 1000W? I haven't - I've used the figures issued by the manufacturer who told me they were derived from many test measurements on many ovens and accurate in respect of all models including the "modern" gas one. Given that situation, it would be rather difficult fo ryou to assert that mine is the only one that achieves those figures. True, if I was to believe that all the manufacturers data is wrong and your single example is the only one that is right. "The running costs of these cookers is about £400-500 per annum" (Aga salesman). From the figures Aga quote a 4 oven gas Aga uses 527kw/hr a week or 27.4 Megawatt/hrs per year. At present gas prices that is an annual bill of GBP 540 - GBP 600 per year depending upon supplier. If you read *all* of the data sheet you would see that the word "typical" is used. They don't say what "typical" means or how they measure it. Are you seriously suggesting that they would deliberately chose an atypical pattern of use to worsen their stated figures? Don't you think there is at least a slight possibility that the manufacturer knows a bit more about the subject than you do? Quite possibly the way you do (or don't) use your cooker achieves better results, if so isn't it more likely that it is your usage that is unusual? -- Peter Parry. http://www.wpp.ltd.uk/ |

You are describing the performance as mediochre based on your experiences of an old model No I am not, they are all mediocre. Only by your definition. Some users may have found their mediocrity to be acceptable and that their style statement or social cachet is more important; it doesn't alter the fact that they are not very good all round cookers. Based only on your definition. I completely disagree, based on my criteria and experience of a more recent product. More recent? The damn thing was last updated about twenty years ago. It still uses the same mechanical thermostat control it did in 1970. So what? It works perfectly effectively. Running costs are not astronomic. I already gave you the figures that I get, and do not regard those as astronomic. You might not, even on your figures others might feel differently. However you have singularly failed to explain why your figures are so much at variance with the manufacturers ones. The "well they are nice people and don't want to upset people" excuse really is pretty lame. As I have repeatedly said; I can only explain my measurements. Aga quote "typical" figures. They don't say how they arrived at them. I could gather firewood for free and cook on that, and argue that anything where I have to pay for the energy is astronomic. It's a relative term. If you want to cook using pound notes as fuel that's entirely up to you. Don't expect to be believed when you claim its really economical though. I really don't care. For the umpteenth time, I know what I have measured and I know the costings that I get that result from it. Yours appears to be the only Aga in the world to achieve this though. Every other Aga manages more like 1000W standing load and this increases up to 5,000W when cooking. How many modern gas models have you measured at 1000W? I haven't - I've used the figures issued by the manufacturer who told me they were derived from many test measurements on many ovens and accurate in respect of all models including the "modern" gas one. Given that situation, it would be rather difficult fo ryou to assert that mine is the only one that achieves those figures. True, if I was to believe that all the manufacturers data is wrong and your single example is the only one that is right. All that I have said is what I measured. I have no idea how the manufacturer arrived at their "typical" figures, and neither have you. "The running costs of these cookers is about £400-500 per annum" (Aga salesman).

I have no idea what they do to make their "typical" measurements and I don't really care. Don't you think there is at least a slight possibility that the manufacturer knows a bit more about the subject than you do? I'm sure they do, but it isn't relevant and doesn't negate the figures that I measured. Quite possibly the way you do (or don't) use your cooker achieves better results, if so isn't it more likely that it is your usage that is unusual? Cooking between 1 and 3 meals per day from basic ingredients does not strike me as unusual. -- ..andy |

If you want lightly seared tuna steaks on a bed of couscous with roquette salad and a balsamic drizzled garnish, an aga is of very little use to you. I disagree. I can sear oily fish very well on the griddle. I don't bother with the couscous and limit the balsamico. The biggest danger of te aga - and its reputatin for gghahstly food - comes from stupid housewives who have discocvered that the warming oven means never having to time your meals properly..meat that gest cooked too early, and just about anything else, goes in there to wait for te veg to be ready. Result is soggy and disgusting. Unnecessary as well. Timing is pretty easy. Its far too complex for most people. More good food is riuined by lack of having a schedule, than good food is concocted by createive use of ingredients. Runs a restaurant in Bray which isn't bad, although he does specialise in scrambled egg flavoured ice cream. Nouveau ****** then. |

Excuse me, who mentioned water heating? I am talking about calories (fuel) in and heat (out) to the room. Less heat goes up the stack on an aga than on an average boiler - thats all. You will be telling me next that an electriceater is 0% efficient because it doesn't heat water at all. Your other aname isn't Drivel is it? But if at all possible, hedge yor bets. If you are on gas, get a gas hob as well - the gas aga companion is actually nice - electric ovens, gas hob, and a gas aga is the best of all worls..and on oil with no gas the electric companion is also advantageous. Something else which needs to be factored in is price. A new four oven gas Aga today costs over GBP 7,000. If you want the companion module - a simple double oven and hob it adds a staggering GBP 2,600. On top of that you need to add the cost of reinforcing the floor. Get the two oven aga then. You don't need 6 ovens... GBP 9,600 for a cooker which then costs a further GBP500 a year to run simply isn't worthwhile when set against its mediocre performance. Neither are most things people fill their houses with. |

If you want to buy a cooker then both price and performance are usually important factors. Thats a bit like saying that if all you want is a splash of color on the wall,£80,0000 for a Tissot is a waste of money. Agas are not JUST cookers. They are heaters of a certain character as well. It is simply ridiculous to compare running costs with a gas cooker. Lets say that its cheaper to heast your house with an aga than a wet radiotor ans see what you think about that... 6500 is a fair price for an installed CH sytem let alone adding a cooker on teh price :-) |

That's your assertion based on criteria that you deem to be valid for you. You can't say that something is or isn't the best for other people, because their criteria are almost certainly different. Of course, I once used to visit a shirt maker in Belfast, at the end of their line identical shirts got put into one of three baskets at random. One went to have a well known designers label sewn in, one had a well known clothing stores label sewn in and one had a generic label sewn in. These identical shirts sold for GBP120, GBP40 and GBP10 respectively (the manufacture got GBP4 for each no matter what the label. I'm sure each of the purchasers felt they got value for their money because their criteria were different no matter that the product was identical. So you think that e.g a baby belling is exactly the same product as an Aga? Hmm. Again, you can't assume that everyone's criteria are the same as yours. I'm not, I have never underestimated human irrationality. |

"The running costs of these cookers is about £400-500 per annum" (Aga salesman). Indeed, that is consistent with my experience..BUT my heating costs with a wet central heating system are about 50% more than that just for the winter...in spring and autumn the aga does that job. From the figures Aga quote a 4 oven gas Aga uses 527kw/hr a week or 27.4 Megawatt/hrs per year. At present gas prices that is an annual bill of GBP 540 - GBP 600 per year depending upon supplier. That is significantly more than I spend on heating the whole house, the hot water and all the cooking fuel for a complete year. well we don't all live in pokey little hovels with the doors shut up tight so we can smell our own farts. |

The Natural Philosopher wrote: But what energy costs? Agas are MORE efficient than CH boilers. That's complete nonsense, surely? How can an open-flued non-condensing appliance possibly compete with a modern condensing gas boiler? Quite easily. It uses a long flue path to extract the heat down to an effkux temperature up the flue of about 35C. With CH water running at higher than that, even in a codensinng boiler, more heat has to go out of the boiler flue than the aga flue. The ONLY thing that marks boiler efficiency is how hot the exhaust gases are when they leave the house and go through the insulation. That and the initial combustion temperatures, which are fairly similar in both cases. |

I only have experience of one fan oven and it certainly does not discharge hot air into the surroundings. If it did why wouldn't the surroundings (kitchen) temperature tend to rise to the temperature of the oven and the kitchen be filled with oven fumes? What is wrong with this equation? |
