Of course, the price of oil has since increased (latest price I have

1 litre of 28 sec. Kerosene = 10 kWH = 43p
10 kWH electricity = 115p

That's an impressive saving you're making there, bub, paying about three
times more to heat your home using electricity than the cost of using CH
oil.

But with oil I would be heating parts of my home that I don't reach!
Therefore you are not comparing like with like. With CH you cannot
'dose' the heat like you can with a fan heater, whose heat is
instantaneous (no pipes to heat up, etc). With CH you don't feel any
benefit for at least 20 minutes, whereas with the fan heater you feel
the benefit within about 10 seconds. Meanwhile I would be paying for
the oil needed for those 20 minutes during which no benefit is
perceived.

You have a cr@p system if it takes that long to have an effect.
Mine is 50,000 BTU into a copper heat exchanger into low water content
radiators.
It takes no more than a few minutes to warm up.

It doesn't hold the heat much either so it doesn't overshoot the programmed
temp.
