check to see if setiment has settled on the pilot....blow it out with air if it has. This issue comes up often with water heaters and rv refers. If that is not the problem and the pilot remains lit, but never increases when the thermostat is turned up, you probably need a new gas valve/thermostat.
when he soldered the connections on these pipes.. he may have partially blocked the flow with solder inside..if its restricted up to 50% then its a hell of a pressure loss..hot water is always lower in pressure anyway..also take the shower head and dunk in a clr solution it may have calcium deposits inside the small plastic orafices in it..
Ok i intall tankless water heaters and sell them and repair them . The trouble your are hving is more than likely ,the mixing valve on your shower has a ajustment on it to prevent you from burning your self . that is the number one reason in showers when water never get to temp . What it is doing is addng cold water to your shower for you bummer . Take handle off and adjust water temp to your hottest setting . Some times you have to remove the low flow washer in shower head to get the right flow . also every time you start up your hot water it shouldbe set all the way ot other wise withe the battery 2 D models the unit will not sence flow and shut off the unit ,with some units it is a fine balancing act to get them adjusted right. If your buying a tankless water heater always buy a blower type unit that has a computer that runs it . You will be happy . If the Battery operated unit is for a cottage or a smallcabin then your just going to have to fix the pumbing to make it work right many of the safety features of the newer showers are not made to work well with tankless water heaters .
you should be able to look online and copy manuel....but most systems have a temp limiter under handle...plumber probably did not set far enough to left for hotter temps...after you pull handle you should see a limiter pull and turn all the way left and reset....you should now be ok...good luck..
the problem is the hot/cold mix is set wrong ---
remove the water control handle to expose the mix valve -- you should see a small set screw that will either increase or decrease the travel of the hot water valve. --- sometimes instead of a set screw there is a little pop off plastic set ring,, pop off and set to a more advanced travel.
this will increase the amount of hot water that flows to the shower head and the bath tap.
u need to adjust the scald protector all single handle units are shipped in cold position for safety reasons if have paper work for handle it explains how to adjust if not unscrew handle and remove on handle / valve stem will see a red and a blue plastic clips pull back clips and turn slightly and push back do this till desired hot and cold setting are to your liking replace handle and your done
I had the EXACT same problem (installed my tankless last winter and worked fine, now this summer it fluctuates, have to turn the shower completely off and then on again to get any hot water and then it only lasts for a couple of minutes!) Argh - it is frustrating!
Here's what I found: the demand for hot water is lower during the summer (hot) months because the "cold" water coming in is already quite warm. You don't need as much hot water to make the shower temp comfortable. SO, my tankless was shutting off due to low flow demand. I've removed the flow restrictor from my shower head and it helped alot but didn't completely solve the prob. Next step is what has been recommended to me by several people but is much more expensive - change the pressure valve on your shower to a temperature valve. Or just wait til winter and it should work ok again :)
Problem new or old? How long you have unit? Sounds like not enough flow to keep burner on. Tankless need at least .6 gpm to keep hot water flowing or else the burner fires then shuts fires then shuts and you get a sandwich effect...hot cold hot cold. If you have new diverter valve in shower -vs- old two handle type try turning hot water ALL the way ON and see if hot stays hot. If it does stay hot then slowly adjust to cool and see if you maintain a good MIX for proper temp. If it goes cold again try this......LOWER control pad setting to a comfortable 105 degrees (ladies) 100 degrees(men) and turn shower valve all the way to HOT. See if your temp remains consistant now and if it does then problem solved. Tankless mindset...set temp on control pad and stop trying to MIX at shower valve. Thats how these things work. Thats why I install a control pad in each bath and one in the kitchen for adjusting ash temp during dishwasher on time. ditto for wash machine. You should never need to turn on cold water if your unit is set to proper temp at controller. Hope this helps
