Hello,
Could someone tell me if we can know how many liters of fuel is 1 kWh?
Obviously this depends on the efficiency of the boiler, so let's say an efficiency of 70%
Thank you in advance
cordially

1kwh = how much liter of fuel?

No, it's just ...
1L of fuel oil = 10 kWh approximately ...
at 70% efficiency, this will make you 10 * 0.7 = 7 kWh useful per L
To make 1kWh useful you need 1/7 of a liter = 0.143 L ... = 0.1 / 0.7
Your reasoning to add 30% to correct the yield is wrong.

To have an order of magnitude we can remember that
10kWh = 1L of fuel oil = 1 m3 of gas
To be more precise, you must already know if we are talking about PCS or PCI (Higher or Lower Calorific Power) knowing that PCS = PCI + latent heat of condensation of water.
The PCS is therefore when we manage to recover the heat contained in the water vapor that results from combustion.
In fact, a condensing boiler is needed (properly regulated: with the water return cold enough to allow the condensation of steam). And again, we never recover all the energy.
Here are the values:
............. gas ..................... fuel oil ............. wood dry
PCI ..... 9kWh / m3 ............ 10kWh / L ........ 5kWh / kg
PCS .... 10kWh / m3 ........... 11kWh / L ....... I don't know
10kWh = 1L of fuel oil = 1 m3 of gas
