How much in litres per hour is this boiler likely to consume?

The documentation should have that information or it might be on the
rating plate. Our big cast iron lump has a spec that around 7l/hour
but it is big, 38kW output. Oil has about 10kW/l of energy

Watts aren't energy, they're power. Joules are energy.

He meant kWhr (or electricity units if you prefer). 28sec oil, or
kerosene, is 10.35kWhr/l. So 85% efficient boiler and 24.68p/l the
equivalent unit price is 2.80p.

BTW in case anyone is interested the figures for LPG are about 600
units in 47kg (the large bottle). So at 26.50 per bottle that 4.4p
per unit. Add in the boiler efficiency and full rate electricity is
cheaper than LPG!
