What causes REMEHA Quinta Pro 45 temperature of heat exchanger to be too low?
D
Duane FisherAug 28, 2025
If the temperature of the heat exchanger in your REMEHA boiler is too low, it could be due to a bad connection, the sensor not being connected correctly, or no circulation. Check that the sensors are operating correctly, and that the sensor has been fitted properly. If necessary, replace the sensor. Vent the air from the CH system, check the circulation (direction, pump, valves), the water pressure, and the cleanliness of the heat exchanger. If present, check the boiler type parameter setting.

Why does REMEHA Boiler have maximum difference between the flow and return temperature exceeded?
J
Joshua SharpAug 30, 2025
If the maximum difference between the flow and return temperature is exceeded in your REMEHA boiler, it could be due to no flow or insufficient flow, or a sensor error. Check the flow (direction, pump, valves), the water pressure, that the sensors are operating correctly, that the sensor has been fitted properly, and the cleanliness of the heat exchanger.
