And where is the heating element of a water heater?
In an electric water heater, the bottom heating element is the workhorse as cold water is supplied to the bottom of the tank. The upper resistance is used only when there is a strong demand for hot water and is only used to heat the water in the upper part of the storage.
Why is my gas boiler not heating up?
A broken immersion pipe can then cause cold water to enter your home’s hot water pipe before it has warmed up sufficiently. Another reason hot water is not hot enough is buildup in the water heater. Since the water is inside the water heater and is heated by it, these deposits settle to the bottom of the tank.
How do you know if you have a bad thermocouple?
If the flame is not burning at all and you are sure that the gas is burning, there is probably an obstacle in the ignition tube. If the flame goes on and off when you release the gas control knob after holding it for the recommended 20-30 seconds, there is an indication of a thermocouple fault.

How big is the socket of a boiler element?
Guide x 11/2 inches. Hot water outlet. The 6-point opening is designed for the most common size of the electric boiler resistor and fits snugly over the hex end of the resistor so you can use maximum torque without slipping.
Which element of a water heater comes first?
The top one heats the water at the top of the water tank first. When it reaches the set temperature, it will turn off and send electricity to the lower element. So let the upper one warm up before checking the lower one.
