Heaters in, fitted and now pumping hot water

Very easy to fit, fired up first time - takes about a minute for the water to make its way through the reel, and about 2 minutes to reach the desired temp.
The only thing I have noticed with mine is that it will only fire up, with the water regulator set at its lowest setting.
I'm still getting a good flow rate , so I'm not too concerned.
Alan, does yours do this?
I need to get some longer hosing to make a neat job of it, a piece of chequer plate behind the heater would look more professional, and find a tidy solution to secure the gas bottle.
But its up and running.... so looking forward to next weeks work.
