Need some advice on a Tank less LPG water heater installation?

I installed a tank less LPG (Propane) water heater and am having issue with it. While taking a shower after the water is adjusted to the level I want it, while taking a shower the temp level will change to completely cold water!! Without me even adjusting the hot water handle to regulate it myself..why is that problem occuring? Is there an easy fix for it?Need some advice on a Tank less LPG water heater installation?
It all deals with water flow. You must have at least 1/2 gpm flowing through the heater for it to heat the water. Less than that and it will shut off and cold water flows through. This isn't a large volume.


Solutions:


Set the temperature at 120 degrees instead of a higher temperature. This way you will have more water flowing through the system, because you will use more hot water and less cold.





Make sure the holes in the shower head are not clogged. This will restrict flow.





Pressure in the lines. If the pressure is below 40 psi, you may have problems maintaining the water flow. If you are on a public water system, this should not be a problem. If you are on a well, you may notice this as an increase in water flow when the pump kicks on. If so, increase the pressure in the pressure tank.





We have encountered all of these at one time or another with our system. Once you get it figured out, you'll wonder why you didn't switch sooner.Need some advice on a Tank less LPG water heater installation?
I am having the same problem. This is excellent advice. How do I turn up the pressure to my well??

There is a limit to how many gallons per minute the heater can heat,usually about 4 gallons. Try a low flow shower head.
turn the temp to 120.





make sure gas and water valves are fully open. there could be air in the gas line. double check your work.
