Something else which needs to be factored in is price.


Why?


Because most people have to buy things and both cost and performance
are factors. 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.

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.

"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.
