Usually when you are having a problem at only one fixture, and not any others it is a sign that you have a faulty fixture. Hope this helps.

There are not many ways a do-it-yourselfer can fix a tankless.
In contrast with tankless, tank-type water heaters have generic troubleshoot steps that lead to a quick diagnosis, and same-day repair of almost any brand. Most times a tank-type heater repair can be DIY.

SOURCE: I installed a dhc tankless heater, but when I open

Hi and welcome to FixYa, I am Kelly.

What is happening is that your cold water flow is greater in volume (gals per min) than your hot water. So when you open the cold water it is mixing with the hot water inside the faucett or shower plumbing and actually reverse flowing back into the hot water heater plumbing. The reverse flow slows the water flow sensing turbine inside the heater and it is thinking that there is not any water flow. (There isn't actually due to the equalization of water pressure when you open the cold water faucett) Since this is a safety feature of the tankless heater to keep it from overheating, it shuts off.
Somewhere in the hot water plumbing there is a major restriction. It may very well be the internal plumbing of the tankless hot water heater or the flow detector design.

There are 2 ways to correct this. The easy way would be to restrict the available cold water flow. You can do this by installing another shut off valve inline with the cold water plumbing and just not open the valve all the way. You would have to adjust the setting so that the hot and cold water can be on at the same time and the hot water heater stays on. The hard way is to locate the hot water flow restriction and eliminate it.
It is possible.... if you have a flow restrictor in a shower head or a screen in a faucett areator that they are partially clogged. Clean any flow restrictors and screens then see how the hot water heater performs before you start modifying plumbing.

Thanks for choosing FixYa,
Kelly

SOURCE: my tempra20 plus will only deliver 90egree water

Hi,
Is this a new install? Or is it an existing heater that all of a sudden went cool?

If it is new, then the water flow is too much and you need to cutback on the amount of water that can flow through...
If it is an existing install then a heating element has gone bad...

Tempra 24 installation. No hot water. No power led on fron cover. Is the led supposed to be on all the time or just when water is ran?


First, check the circuit breaker. Also, did you upgrade to heavier wiring and a double 60 circuit breaker when you had this installed?

Should the red lights be flashing or be on steady


A solid light is what you actually want.
If you have a blinking light, the unit is unable to keep up with the flow of water.
Slowly turn on the hot water for your bathtub until the light starts to blink to find your limit. in other words your tankless heater is too small for your needs.
The 24 model is more for houses with showers or slower flow.
The 36 or higher model has 3 sets of heaters to be used with a bath, higher flow.

Which type Richmond water heater?
Is this a tankless water heater or tank-type?

Tankless are notorious for 'cold water sandwich' under exact conditions you describe. You might need tankless with larger BTU burner.
Don't install a tankless.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

If you have tank-type water heater, then I suspect a clog in the hot water line, or single-handle faucet cartridge in show is going bad.
Same problems can contribute to tankless problems.

Water turns cold very quickly


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 :)

Tankless on demand water heater.


Tankless water heaters normally take a little longer than a regular heater to provide hot water because they have to start and get warmed up. I'm guessing the heater uses a pilot light and that the short amount of hot water when you turn on the tap is hot because when the water is sitting still in the heater the heat from the pilot light is enough to get it hot. The tub faucet will get hot a lot faster than the shower because it lets a lot more water through and empties out the pipes faster than the shower. You could probably speed things up by letting the tub faucet run on completely hot for like 10-15 seconds and then turning on the shower.
