I don't use mine as on demand, rather I circulate it to warm the tank of water.
I have just been showing a mate the difference between the L5 and the Kampa Geyser and it seems that the L5 would only ignite when the pump was on speed 7 whereas the Kampa Geyser worked down to speed 3?
For those who use the L5 on demand what will yours work down to and do you modify it?
