Why is there no hot water from my STIEBEL ELTRON Boiler?
- A
  Amanda YangAug 2, 2025
  If your STIEBEL ELTRON Boiler isn't producing hot water, it could be due to a few reasons. First, check if the utility is controlling the load. If the safety thermal cut-off has tripped, reset it. Insufficient flow rate can also be the culprit, requiring the correct size pump. Lastly, a plugged flow sensor can prevent hot water; in this case, activate the thermostat and clean the flow sensor.

Why is the water not hot enough in my STIEBEL ELTRON Boiler?

  If the water from your STIEBEL ELTRON Boiler isn't hot enough, several factors could be responsible. It might be due to water flow that's too high, so try reducing the water flow rate. Low voltage can also cause this issue, ensure the unit is supplied with the correct voltage. If the glycol/water ratio is too high (more than 20%, less than 50%), adjust it. Finally, check if any manifold or ball valves are closed, and if so, open them.
