Rayburn efficiency?

Mine has suspension -- whacking great leaf springs -- but no shocks, which I suspect is what Peter meant. It does make tackling "traffic calming" an interesting enterprise.

They *are* taxed, but at a rate of £0.00. You can drive them on a normal licence and my insurance is around £40 (TPO, but allows for 7 passengers and 3 drivers).

All they have is a set of leaf springs (no dampers) which move about an inch when 3 ton is put on the back.

They go very slowly :-)

They do if you try anything over walking pace.

Not when you compare the cost.

They have a tax disc - but it is issued free, much to the confusion of many post office staff.

Car licence and fully comprehensive insurance is about GBP70 per year. The combination of a need for short and infrequent journeys, the type of load and the very low standing cost make it ideal.

I actually did some tests on the aga with an oven thermometer. Wih all hobs closed it was about 210C.

After an hours cooking on both hobs, it was 195C.

7% drop.

Its an oil fired aga with thermosat controlled burner.

What this shows is that

- yes, flat out it cannot maintain oven temp with both lids up but

- since it takes 4 hours to heat up, even with no burner on, it probably takes 4 hrs to cool down..and an hours hob cookng with a modulating burner is not really going to affect cooking temps enough to be noticeable.

I THINK the oil flow rate on 'full' is about 3x what it is on 'low' which implies that its probably only about 1.5KW into the ovens, max. As I would assume that 'low' oil flow is less than what it does at 'idle'

I've measured the gas one and it's able to regulate even more tightly than the 7% that you got..
