Are you saying put some cold in with the hot? This would use more water not less surely?I'm on my 2nd heater (not l5). I binned my first heater due to flow/heat issues, and was struggng with my 2nd (not l5) although it was marginally better.then I fitte a thermostatic mixer valve and the problem disappeared!It seems to "ask" the heater for hot water all at once to mix with the cold to provide a constant temperature. you can set your heater on full if you like, and it just fires up and supplies hot water as required. and i've not had a heat/flow problem for 4 months nowI'm not really up to speed on this so don't shoot me, but I believe this would be more use on the old fashioned diesel heating systems , the newer on demand gas systems use too much water- that's what we are saying-. Nathaneal has hot wired his to disable the manu's settings.

I've the 1ltr/min one and it fires up at 1/2ltr per min or less!To bypass the flow switch all together you need a 6V relay. The coil side of the relay goes to the pump wires, and you run the wires that used to go to the flow switch to the normally open contacts on the other side of the relay. Your pump starts, activates the relay, which switches on the heater regardless of flow rate,... pump stops, the relay contacts open and the heater stops.The L5 has an overheat sensor,.. so if your flow rate is low enough that this kicks in you may have problems with intermittent heating,.. but set to minimum power I'd expect it'd be rare that this would be a problem.

I just noticed you have now got a new HOT section on your forum GR8
I was under the impression you could not fit a gas heater to a van?

They do a diy fit kit, thats good. I was just being nosey, i already had a new hot system fitted at waterfed pole systems in grantahm. I know they do a bolt on as well, either from van tank or with a seperate tank. Mine is from the vans tank, alot less messing about!

You can have a seperate marine tank or something but i don`t want smelly deisel every where in the van,just turn it on and that`s it no need to keep filling it up and running out of juice.

The 1 i`m getting is better aswell because it`s since been reduced in size in overall footprint so it takes up hardly any space in the back unlike the omnipole 1.
