How would you measure efficiency anyway? On my gas one, the steady
state burn rate is about 700W. We have a conventional flue exiting
through a special ridge tile. By the time the flue enters the roof
space it is almost cold so almost all of the heat is released either
by the appliance itself or the flue within the envelope of the house.
In that sense there is very little waste of heat during the 9 months
of the year when heating is required. In effect this amounts to heat
that the CH does not need to provide.
One can argue, therefore, that from an energy efficiency perspective,
this is a better scenario than the typical, poorly insulated oven and
hob arrangements that require the user to open the windows and waste
the heat because of overheating of the kitchen.
I would expect the oil fired unit to be similar from the perspective
of what is released into the room, but possibly slightly more through
the flue since AIUI oil flues run hotter.

The way I see it there are two efficiencies involved:
 The efficiency with which the Aga converts the fuel's energy
 The efficiency of the way in which this heat is released
into the house.
I suspect (but have no numbers) that on , an Aga will come a
little, but not by much, lower than a high pressure oil boiler.
As for , it'll depend a lot on the time of year, as you point
out. In the colder months, the heat output into the room is a
useful contribution to the CH. In the summer, it's a PITA.
I would guess that overall, Agas would come in as being a bit
less efficient than a cooker/CH setup, but not by so much that
it would cause anyone to worry too much.
What I object to is that they're high maintenance, difficult to
clean, extremely expensive, and take up an inordinately large
amount of space for the functionality they provide. I'll stick
to my oil boiler and fan oven ;-)
I don't see why, particularly, but OK.
That depends on the size and design of the house. It never causes us
I disagree on most of those points.
Maintenance on a gas burner is once a year and is an easy DIY job for
the competent. On an oil one every six months, but AIUI many oil
burning appliances need that interval as well so it comes with the
Cleaning is really easy. The majority of things cooked in the ovens
are done so either covered or at a low temperature where there is not
splashing. In the roasting and baking ovens, splashes are carbonised
relatively quickly and can be swept out. The enamelled top can
easily be wiped or better, cleaned with a steam cleaner very quickly
and effectively. There is no messing around with caustic soda and
There's loads of functionality. Apart from the flexible and excellent
cooking there is the ability to warm crockery (I believe that serving
hot food onto cold plates should be a capital offence), warming
ingredients, drying herbs, warming clothes, airing clothes and caring
for sick animals. My cats, who spend 23 hours a day in front of the
Aga in the winter would also suggest that it's a pussy magnet.
I went on a cruise once in 1963, it was vile beyond belief.
You would enjoy it pronably. I bet you go to Butlins every year.
For teh cost of the Aga I could have gone on Safari. Never mind. I'll go
I can do both. However I wouldn't choose a cruise or any other form
of vacation where somebody else does the organisation. From bitter
experience I only trust two people to make my travel arrangements -
one is me and the other is an excellent person at a business travel
agent that I have used for 20 years.

Yes the oilways and the burner pot are blocked with carbon from a slow build
up as the hot oil degades.
No 6 months is the proper service interval.
If you have your Aga serviced professionally new wicks are usually fitted
each time. This is overkill , a set of wicks can last for several years.
They are only really necessary to light the burner and get it to vapourising
If you have not got a manual I suggest you get a copy.
Bottom warming oven is also a pussy magnet! If you let them. And the
hand(guard) rail along the front is great for leaning your butt on.. But
don't mention it to a friends wife who came out of the bath and went to
lean on the Rayburn to dry off, as you do. Only problem my friend had
removed the rail to repair some blemish.... you can imagine the rest, burnt
butt and one seriously unhappy missus :-)
Yea they have lots of uses. My mother had even used the warming oven as a
surrogate mum chicken. The plate rack is a great place for drying things in
a hurry. Paint brushes etc.. if you can get away with it!
