SOURCE: hot water is cutting out after 2 - 3 minutes whilst showering

check the screen on the cold water intake on the cold side,, you might have to flush the system out, and do you have the shower head water restricter in, if not you may be using to much hot water,,, how many other hot water fixtures are running at the same time? try running just the shower,,,if this is a tank water heater the dip tube could be bad that is on the cold side it takes the cold water to the bottom of the tank and forces the hot water out,, if you ar only getting a couple of min of hot water and the dip tube is bad it is not going to the bottom but just at the top and not getting all the hot water you will need a plumber

SOURCE: Not heating water hot enough or as much water.

You probably have a bad heating element. Probably the upper element.

SOURCE: atwood rv water heater model G6A-8E heats water to

Normal causes for that would be by-pass valve not in proper position, or defective, allowing cold to mix with hot, or thermostat not touching up against tank properly, or defective. Do you know where that thermostat is?
Look where the black foam cover is, with white letters, below pressure relief valve. One is lettered ECO, other THERM. If you note where the wires go, so as not to mix them up , and pull them off, then peel back the foam cover, you'll see 2 little round discs, that are held against the tank by a small spring. They need to be checked that they are in there properly and are up against the aluminum tank.

Rennai hot water heater very slow to heat up!


I would check the gas pressure at the burner. It should be 3.5 inches water column on the manifold. Hope this helps.

What can i do to get my water heater heating the water hot enough for a hot shower, water is just warm these days?. Any suggestion?


There's an, "Aquastat " on the water heater, turn it up one increment and see if that helps. The water heater should turn on in under a minute if it's functioning properly.

Hot water varies


I do not know how old this unit is or what model but many water heaters are not sophisticated enough to measure the temperature, but heat based on water flow and temperature rise. To start, tankless water heaters turn off every time you turn the hot water off. Lets use an example. You use the facilities, wash your hands then turned off the water and take a shower. You will bring the already heated water (from washing your hands) from the pipe up to the shower. Then the cold water that comes into the pipe from the reactivation of the water heater comes up the hot water pipe with warm then hot water just behind.

If this is not your problem, keep reading. Every unit I have been called to see were installed wrong. Check your installation manual to see if the problem with the system started with the contractor.

First, check the temperature of the water from the heater. If it is too hot and you are mixing too much cold water in, the unit will turn off because there is not enough water flow to keep it running.

Second, turn off the valve at the water heater and turn on the hot water at a faucet. If the water does not stop running, there is a "plumbing cross over" usually caused by a failing pressure balance valve in a shower.

Third, if the unit has not been serviced, go to bosch-climate.us to find a tankless water heating professional in your area. Totally Tankless LLC

How do I troubleshoot a 6kw 240 volt circulation heater. This heater is on a baptistry; they fill it up before service starts and use it 90 to 120 minutes later and water is still cold.


Hi,
It is very possible that you just are not giving it near enough time...
I have worked on them before and they do not heat the water very fast....
you will need to give it at least 12-24 hours to heat the baptistry properly...
That heater will only heat about 30-35 gal./hour....on a 50F rise in water temp. ....figure how many gallons you have there and then do the math...

HEATER WARMS UP AND THEN GOES OUT.THEN IT HAS TO BE RELIT TWO OR THREE TIMES A DAY


Relighting the pilot of any water heater is a pain. The first thing to do is call the water heaters manufacturer for information on your specific make and model. If your water heater is under warranty, they will provide technical advice and free parts.
1. Replace the water heater's thermocouple. Make sure the pilot flame is centered on the shiny end of the thermocouple; it requires a certain amount of heat to produce enough electricity to open the main gas control valve.
2. Replace the main gas valve control.
3. Replace the water heater; I know this not what anyone wants hear.

The temperature indicator changes as soon as I begin to take a shower. How can you help me.


try unplugging the controller to see if it's a glitch in the contoller. If not you probably do not have enough gas running to it so it can't heat the water fast enough due to lack of gas
