cost - to buy they are around 7k for the basic machine or £375 + vat plus pallet delivery each way you get the machine for a week but the majority of cleans for brick restoration are a day, maybe 2 so we hire either nilfisk or ipc steamers which produce around 120 degrees and cost £65 per day hire.
the next brick restoration job i might hire the thermo for a week just to see if its better on the initial clean and stubborn parts where at present we need to re apply the cleaning solution
