Most heating systems are capable of having a Power Flush carried out. If you have an old gun barrel heating system with GB or steel pipes, we will run the Power Flush at a lower speed to reduce the pressure on the steel pipes.
Usually a 1/2 day for a standard house. If you have radiators with cold spots, we may need to insert a cleansing chemical the week before we call. This will help to soften the debris in these cold spots. This makes flushing more successful.
A Power Flush is not required on all heating systems, though it can be beneficial for solving lots of heating system problems.
