how long would 100 litres of oil last just for heating ina three bedroom house on 4 hours a day?

Question

100 hundred litres of oil would last for how long in a three bedroom house used 4 hours a day just for heating

Answer 1

I always use a rule of thumb: 1litre = 10kWhrs

So you have 1000kWhrs

A medium house runs at about 20kWatts
so you have about 50 hours of oil or about 10 days.

This is all very much rule of thumb but you can see how to get an approximate time with the number of radiators * their power that you will use. (2 to 3 kW per habitable room)
