[Small but perfectley formed]

Hi Richard you use PF high viz hose with hot is your system gas or diesel and what temp do you have your water.

[Richard ham]

Hi its diesel, only the best for me:-).

My water hits the windows from the brush head approx 39-46 degrees.  60 degrees is maximum for upvc, to be covered by your public liability. I dont ever turn it down or run cold.

The water heats to nearly 80 degrees from my heater, happy days.

In my experience of hot systems, this system runs perfectly for us. 

I run 2 operators from the same heater. Both with 100m hivis hose:-).

Hope this helps.
