We are starting our self-build shortly and have decided to buy a second-hand compressor and concrete mixer and sell them afterwards. What should we allow in our budget for fuel costs? And what will the plant be worth when we are finished?
It depends on how long you use the plant for but here are some approximate figures showing the number of litres per hour for mixers and compressors:
Item Litres per hour
Concrete mixer compressor 5
40kW 8
75kW 16
100kW 20
It would be prudent to write off the resale value of the plant in your budget at this stage.
