customer of mine has a 12kw instant heat water heater in a small cabin for kitchen sink and shower. It needs a flow of at least 3l/min to turn on. We have set the stop cock to get this flow rate and it turns on ok and gives adequate water of around 40oC. Trouble is if it's left over night etc it needs the stop cock turning up a bit to more like 5l/min to get it to operate and then you can turn it down again to 3l/min. Trouble is at 5l it's not hot enough.
Any better ways to control the flow and make sure it operates every time?
This is in a holiday let they rent out so it needs to work every time.
