Question about Eemax EX280T2T Series 3 Whole House Electric Tankless Water Heater

Open Question

Carry out setup and get hot water. 30 mins later freezing cold. Immediately after carrying out the setup, as per the manual all is fine, nice hot water. 30 minutes later water freezing cold. I've checked inside the box and all lights lit up and cannot see anything wrong. This happens everytime I reset the box. Checked the two thermostat dials and both set to max. Inlet set fully opened, and outlet set open only enough to get desired flow rate. Any help would be much appreciated. Eemax EX280T2T

What size fresh air vent do I need in a boiler room with a gas boiler and gas hot water heater with about 220,000 btu combined


I suggest that you run a duct that is 3 inches larger than the furnace duct . and you should run it down close to the floor and aim it in the direction of the furnace. this will trap warm air above the vent and supply an adequate supply of air for combustion. also make sure you have insulated any pipes in the furnace room that carry water or steam you want heat where you live, not going up the chimney.

Hot water recover time


No.
Fold-back elements are low-watt-density, so element does not burn out as easily since heating is spread across more surface area. But recovery remains 16 gallon per hour.
20 amp breaker and 12 gauge wire: max 3800 watts
30 amp breaker and 10 gauge wire: max 5800 watt.
4500 watt element heats 20 gallons per hour.

Instead of changing elements: Set thermostats higher so more cold is added to hot water, and then you have more hot water available inside tank.

Fix problem immediately same day, yourself, for $385, by replacing whole thing:
http://waterheatertimer.org/How-to-install-gas-water-heater.html
Bosch posts some service manuals: or contact Bosch. Lack of error code indicates failed PC board? or bad single-handle faucet cartridge?
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html
Check for crossover where bad faucet cartridge allows cold water to enter hot pipe, so hot water is not drawn through tankless and burner does not activate... but this might not be problem since you hear the tankless clicking

Call local service technician to catch up on required yearly maintenance.

Water takes 30 sec to cover 10m from heater to tap


body { background: #FFFFFF; margin: 0px; padding: 4px; font-family: arial, verdana, sans-serif; font-size: 10pt; } p { margin:0px; padding:0px; } .spwrap { background: transparent url(/wysiwyg_rte/misspell.gif) repeat-x scroll center bottom; } You are talking about length of time to get hot water from water heater.What diameter pipe are you talking about? What type of faucet do you have?
1/2" pipe has inside diameter of .54" and holds 1.2 gallons per 100 feet
10 meters is 32 feet and holds .4 gallons
Average faucet puts out 2 gallons per minute, so 30 seconds you should get 1 gallon of water.
Put a bucket under faucet and check amount of water flow.

Assuming you draw just hot water from the faucet, then 30 seconds is slow for receiving hot water.
If you have single-handle faucet and raise handle straight up in middle, then you are drawing half hot and half cold, so it would take 30 seconds for hot to arrive.

If hot water is slow, the problem might be crossover.
http://waterheatertimer.org/Crossover.html
or low water pressure due to clog in water line
http://waterheatertimer.org/Low-hot-water-pressure.html
Other problems could include clogged water filter, clogged water softener, defective pressure valve, and low water pressure.

I have a rheem hot water tank when you turn on the hot water it comes out nice an hot but not even 30 secounds after that the water cools off and it stays as just warm water. I hear the gas kick in to heat...


Could be your thermostat but it might be your inlet dip tube. Your water heater has a plastic pipe that carries the cold water to the bottom of the tank. When you open your tap, it takes the hot water from the top of the tank, the cold goes to the bottem and gets heated. If this tube breaks, or comes loose, it will short circuit the cycle. The tank is hot but as soon as you start using water, cold water comes in at the top and mixes with your hot water, giving you just warm water. If you have room above your tank, you can remove the union on the cold side , screw out the pipe nipple, and look inside and see if there is a tube. If not you can buy one from home depot or lowes for just a few dollars. Also a water heater should be partially drained annually to remove any solids from the bottom, which will allow better heat transfer.If you find bits of plastic when you do, then you know where your dip tube went. Also if you've had a hot water faucet stop up and it looked like plastic there it is.

Our water keeps fluctuating between hot and cold. The hot water will not stay on. It lasts about 1 minute and then turns to cold. After about 2-3 minutes it will get hot again?


The inlet line to the water heater goes to the bottom of the water heater to prevent the cold incoming water from mixing with the heated water at the top. The tube going to the bottom can come loose.

Turn the water off and relieve the pressure by opening a faucet and remove the fitting where the water enters the heater. You can see if the pipe is still connected.

Heater stops heating water


you have to much volume of water going thru the unit, did you size it properly by haow many baths and showers you have or did you just by the cheapest one,, there is a scale to go by run just one shower and see if it changes temp, with nothing else running,, a shower has 2.5 to 4.5 gal per min,, then you can also check to make sure it has the right size gas line 3/4 from the meter to the unit is required at a min of 2lbs of gas

Vaillant turbomax 28 constant hot water problem.


got your fix, its a calcium buildup in the heat exchanger, and more than likely the rest of the unit, you will need to flush the unit with about 4 gallons of vinegar, you will need to recirculate it for about 20 mins through the unit, then flush with clean water, hook it back up, it might take a couple of mins for it to run properly, but it will, I have had the same problem with Rinnai on demand hot water systems, and it worked like a charm, check the filter thats inline as well, make sure it isnt plugged, clean if needed, also if you dont have a soft water system inplace, you might want to think about buying one and having it installed, that will reduce this from happening again for alot longer period of time, hope that helps
