One of the donations, of £1million, came from an unnamed woman,’ says Maggie mysteriously. The elements will have two wires connected to each one and will either have a big hex nut where they screw into the tank or will be fastened to the tank with a bracket and usually 4 bolts. 2 pick) delivers hot water at up to 4 gallons per minute with 18 KW of heating energy, yet because it only heats the water on demand, uses far less energy overall than a storage tank water heater of similar output capacity. Knowing what I knew, I decided to clean out the water storage tank, even though there wasn’t anything wrong with the water heater. The Thermoflow is larger in capacity than the Bosch electric mini tank, but offers less maximum water pressure range, 115 psi vs 150 psi. At this point you might get lucky and find the easiest way to fix an electric water heater. You are smart enough to realize at this point that all the houses in the neighborhood were built at the same time.
This is the lowest point in the water system. The emergency drain pan that was supposed to catch all the water from the leaking water heater was plugged up with insulation that had fallen into the pan over the years. You will need to shut off the water and drain the water heater to replace the elements. In a future article we will discuss how to replace your valve. If you are sure you have gas, and replacing the thermocouple doesn’t fix the problem, the gas control valve is about the only thing left to check. The pilot decided that this would not be a problem, and so he gave the heater another pull, to push us up further. This looks like a copper wire coming from the control box on front of the water heater and going down to where the pilot light should be. Many electric water heaters also have a separate disconnect box at the water heater, check this too. After confirming that the power is indeed off to the water heater, remove the 2 wires from the element and check for continuity. In order to check or replace a water heater element you will have to turn off the breaker serving the water heater circuit and remove the access cover on the water heater.
Just remove the wires, connect the new one the same as the old one, put the access plate back on and turn the power back on. If you think it was tripped, put everything back together, turn the power on and check for hot water in about an hour. In general, provided you’re comfortable with water lines and basic electrical work, an electric tankless water heater can be a DIY job, while gas water heaters are somewhat more involved to put in. I purchased another water heater and installed it, but I needed to know how bad the old waters heater was damaged. If there is not an intact circuit between the two terminals on the element, it is bad. Many thermostats have a reset button which can sometimes be pushed to reset the circuit and get the water heater working again. There’s not room in one article to cover electrical diagnostics but you can perform a simple continuity check on the elements to make sure they make a complete circuit.
If the leak has stopped, make sure the area is as dry as possible and if you would like to investigate the actual cause, you can turn the water inlet on to see if you can find the water dripping out. Turn the water pump on and pressurize the system. Turn the water temperature down at the water heater. The water lines are often flexible lines that have a nut that you can turn counter clockwise to remove. If the water still runs cloudy for an extended period of time, turn on the supply valve for the cold water to flush out any remaining sediment. This heat from the pilot flame causes a tiny electrical signal to be sent to the control valve, telling the control valve that there is a flame present so it’s OK to let the gas through to the main burner when the thermostat calls for heat.
