See this is my point , although its controlled however how , for 4.5k I would want a dial I could turn to get the temp I wanted at brush head , but from what I have just read its still down to so many variables .
Im no worse of with my L5 really , to get 35 at the head on a 5*c day with most of my hose out Im on the lowest gas setting , if its between 5*c and lower I just pick a spot no further than the first increment of the 3 only the boiler .
Its been the same for the last 8 years , and not failed or blown my eyebrows off yet , touch wood
I had been hoping to get away from the gas this year but funds and time will not allow !
