What to do if Thermann TIHP300 Water Heater has no hot water even with power?
If your Thermann Water Heater has power but still isn't producing hot water, check whether the air inlet or outlet is blocked.
Why Thermann TIHP300 has no hot water?
If your Thermann Water Heater isn't producing hot water, it might be due to the thermoswitch tripping or the high limit safety pressure limiter switching the compressor off. This can happen if the compressor is overloaded due to high ambient or air temperature (above 42°C), or if there's a refrigerant circuit fault. If this occurs repeatedly, consult a local tradesperson to fix the problem.
