Why is my ThermoFlow Kompakte Water Heater heating, but the water is not hot enough?

  There are several reasons why your ThermoFlow Water Heater might not be producing hot enough water: * The user temperature setting may be too low - try increasing it. * The flow rate might be too high; consider installing a flow regulator to reduce it. * If it’s a new installation, the wiring could be incorrect; have your electrician double-check it. * The voltage may be less than 380 volts for 3-Phase models or less than 220 volts for Single-Phase models. In this case, you may need to upgrade to a larger input heater. * You might be mixing too much cold water; adjust your faucet's anti-scald feature to reduce cold water mixing.

  If your ThermoFlow Water Heater's display lights up but shows no temperature and isn't heating, it could be due to several reasons: * The flow rate might be too low. Your water heater needs a flow rate of approximately 2.2L/min / 2.5L/min to activate. Increase the flow rate or check the filter mat inside the inlet connector. * Air bubbles might be trapped. Turn on the unit and open the hot water tap for about 20 seconds to purge them. * The flow sensor might be blocked. Try uninstalling and cleaning it. * The connector between the flow sensor and the main board might be loose. Unplug and replug it.

Why is the water temperature at the faucet different from my ThermoFlow Water Heater setting?
- M
  Melanie HerreraAug 30, 2025
  The water temperature at the faucet differing from your ThermoFlow Water Heater setting can be due to a few reasons: * Your faucet might have an anti-scald feature or tempering valve that mixes cold water, even on full hot. Adjust the valve to reduce cold water mixing. You can compensate for this by increasing the setting on your water heater if you need/want hotter water. * Heat loss can occur due to long pipe runs, especially if the pipes are cold. You can compensate for this by increasing the setting on your water heater if you need/want hotter water. * If the water temperature at the faucet is too hot, check if the flow is too little or the set point temperature is too high.

  If you're experiencing a low flow rate with your ThermoFlow Water Heater, the filter mat inside the inlet connector or the pipe might be blocked. Check and clean the filter mat inside the inlet connector to resolve this issue.
